Local infiltration anesthesia in tenolysis surgery

Ropivacaine is a long-acting amide local anaesthetic agent and first produced as a pure enantiomer. It produces effects similar to other local anaesthetics via reversible inhibition of sodium ion influx in nerve fibres. Ropivacaine is less lipophilic than bupivacaine and is less likely to penetrate large myelinated motor fibres, resulting in a relatively reduced motor blockade. Thus, ropivacaine has a greater degree of motor sensory differentiation, which could be useful when motor blockade is undesirable. The reduced lipophilicity is also associated with decreased potential for central nervous system toxicity and cardiotoxicity. The drug displays linear and dose proportional pharmacokinetics (up to 80 mg administered intravenously). It is metabolised extensively in the liver and excreted in urine. The present article details the clinical applications of ropivacaine and its current place as a local anaesthetic in the group.

Delivery by caesarean section (CS) is becoming more frequent. Childbirth is an emotion-filled event, and the mother needs to bond with her baby as early as possible. Any intervention that leads to improvement in pain relief is worthy of investigation. Local anaesthetics have been employed as an adjunct to other methods of postoperative pain relief, but reports on the effectiveness of this strategy are conflicting. This review attempted to assess the effects of local anaesthetic agent wound infiltration and/or abdominal nerve blocks on pain after CS and the mother's well-being and interaction with her baby. Methods. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (April 2009).The selection criteria were randomised controlled trials of local analgesia during CS to reduce pain afterwards. Twenty studies (1 150 women) were included. Results. Women who had wound infiltration after CS performed under regional analgesia had a decrease in morphine consumption at 24 hours compared with placebo (morphine dose -1.70 mg; 95% confidence interval (CI) -2.75 to -0.94). Women who had wound infiltration and peritoneal spraying with local anaesthetic after CS under general anaesthesia (1 study, 100 participants) had a reduced need for opioid rescue (risk ratio (RR) 0.51; 95% CI 0.38 to 0.69). The numerical pain score (0 -10) within the first hour was also reduced (mean difference (MD) -1.46; 95% CI -2.60 to -0.32). Women with regional analgesia who had local anaesthetic and non-steroidal anti-inflammatory cocktail wound infiltration consumed less morphine (1 study, 60 participants; MD -7.40 mg; 95% CI -9.58 to -5.22) compared with those who had local anaesthetic control. Women who had regional analgesia with abdominal nerve blocks had decreased opioid consumption (4 studies, 175 participants; MD -25.80 mg; 95% CI -50.39 to -5.37). For outcome in terms of the visual analogue pain score (0 - 10) over 24 hours, no advantage was demonstrated in the single study of 50 participants who had wound infiltration with a mixture of local analgesia and narcotics versus local analgesia. Conclusions. Local anaesthetic infiltration and abdominal nerve blocks as adjuncts to regional analgesia and general anaesthesia are of benefit in CS by reducing opioid consumption. Non-steroidal anti-inflammatory drugs may provide additional pain relief.

Inguinal hernia repair is one of the most common operations performed in General Surgery accounting for about 10-15% of all surgeries. Inguinal hernia repair can be done under local, spinal or general anaesthesia. Although specialized hernia centres routinely use local anaesthesia for uncomplicated open inguinal hernia repair, very few surgeons adopt this technique, and prefer performing surgery under spinal or general anaesthesia. We compared the short-term outcomes following open inguinal hernia mesh repair under local, spinal and general anaesthesia in our hospital. (1) To compare the post-operative pain scores among the three groups. (2) To compare the duration of surgery in minutes, the duration of analgesia, analgesic requirement, the time of return to normal activity such as walking, the time of initiation of diet, and the time of voiding after the surgery. Also to compare any complications, such as urinary retention, need for catheterization, nausea and/or emesis, and the length of hospital stay. (3) To observe the impact on health-related quality of life according to EuroQol and patient satisfaction and acceptance of the type of anaesthesia for the procedure. A single centre non-randomised, prospective, observational study was performed in 135 patients undergoing inguinal hernia repair under local (LA), spinal (SA) or general anaesthesia (GA), with 45 patients in each arm, over the span of one year. After approval from the Ethical Committee, and proper informed consent, patients above 18years of age who were to undergo uncomplicated open inguinal hernioplasty were recruited for the study. Lichtensteins tension-free hernioplasty was performed in all cases. The duration of the procedure was calculated from the time of induction or infiltration of local or spinal anaesthesia, till the end of dressing, or extubation in case of general anaesthesia. The duration of analgesia was calculated from the end of the procedure to the feeling of first pain as recorded in the questionnaire. A standard postoperative protocol was employed to determine the pain scores for the first 7days and also to compare the short-term outcomes i.e., duration of analgesia, return to normal activity, complications, post-operative nausea and emesis, analgesic requirement, urinary retention, length of hospital stay, health-related quality of life and patient satisfaction and acceptance were recorded according to standard proforma and EuroQol questionnaire. All the statistical analysis was carried out by SPSS version 16.0. The mean pain scores were lower in the LA group as compared to SA and GA groups from POD-1 to POD-6 (p < 0.001). However, the values from the 7th post-operative days were similar in all three groups and statistically insignificant (p = 0.09). The outcomes such as duration of analgesia, return to activity such as walking, time of first meal and time of discharge from the hospital were all better in the LA group (p < 0.001). The results concerning nausea, vomiting, analgesic use and urinary retention all favour LA. No difference was found among the three groups concerning overall satisfaction and quality of life. In a general surgical setting, we found that local anaesthesia is well tolerated and associated with significantly lower pain scores in the immediate post-operative period and also requires less analgesic use when compared with general and spinal anaesthesia. Patients in the LA group can resume basic activities such as walking, voiding, and initiating diet almost immediately after the procedure and there were no incidences of retention of urine, which was a significant advantage over the other two types of anaesthesia. Patients who were graded as ASA 4 and 5, who were unfit for general anaesthesia, were able to undergo the surgery under local anaesthesia with no postoperative complications. Moreover, the complications and risks of spinal and general anaesthesia are avoided without compromising the quality of surgery and its outcomes. The duration of the surgery as well as hospital stay is significantly less in patients undergoing surgery under local anaesthesia and most cases can be done as a daycare procedure, which is significantly advantageous, especially in low-income settings, with no difference in the health-related quality of life or patient satisfaction and acceptance.

Ultrasound-guided regional anesthesia can be an effective way to achieve analgesia during implantation of permanent intravenous port systems.The aim of the study was to improve the quality of perioperative analgesia during placement of permanent intravenous port systems.Material and methods. The prospective randomized study included 93 patients with malignant neoplasms. Patients were randomized into 3 groups, 31 people each, who were implanted with a permanent intravenous port system in 2019–2022. Group 1 patients were implanted under local infiltration anesthesia (LIA). Ultrasound-guided pectoral nerves block (PECS1) in group 2 was supplemented by LIA. In group 3 ultrasoundguided selective supraclavicular (SC) nerve block was supplemented with LIA. Pain intensity was assessed on a 100 mm visual analog scale (VAS) at rest and while moving at 8, 16, 32 and 72 hours after implantation. The inflammatory postoperative stress response was assessed by the dynamics of C-reactive protein (CRP), interleukin 1-β (IL 1-β), interleukin-6 (IL-6). We also analyzed the correlation of proinflammatory cytokines levels with VAS-measured pain intensity at the stages of the study taking into account a potential relationship between IL-6 and IL-1β fluctuations and the severity of inflammatory and neuropathic pain.Results. In groups 2 (PECS1) and 3 (SC nerve block), pain intensity measured by VAS at rest and while conducting daily activities was significantly lower than in group 1 (LIA). CRP levels were also significantly lower in group 2 and 3 patients as compared to group 1. The lowest IL-6 and IL-1β concentrations after port implantation were revealed in a group 3 in 24 hours after the procedure, persisting through day 3. There was a correlationbetween proinflammatory cytokines levels and pain intensity.Conclusion. Implantation of an intravenous port system under local infiltration anesthesia causes a significant inflammatory response in cancer patients, which can be balanced by regional techniques. Selective supraclavicular nerve block in combination with a local anesthesia for intravenous port implantation demonstrated the greatest analgesic potential and requires significantly reduced amounts of local anesthetic compared to pectoral nerves block in combination with LIA, or only local infiltration anesthesia.

A new method of administering local anesthesia for calf disbudding: Findings from a comparative on-farm study in New Zealand

Local infiltration anaesthesia (LIA) was introduced as an innovative analgesic procedure for enhanced recovery after primary total knee arthroplasty (TKA). However, LIA has never been compared with analgesia based on an adductor canal catheter and a single-shot sciatic nerve block. To evaluate two analgesic regimens for TKA comparing mobility, postoperative pain and patient satisfaction. Two-group randomised, controlled clinical trial. Charité-Universitätsmedizin Berlin, Campus Charité Mitte, Germany between April and August 2017. Adults undergoing primary TKA under general anaesthesia were eligible for study participation. Exclusion criteria were heart insufficiency (New York Heart Association class >2), liver insufficiency (Child Pugh Score >B), evidence of diabetic polyneuropathy, severe obesity (BMI > 40 kg m), chronic opioid therapy for more than 3 months before scheduled surgery and allergy to local anaesthetics. Nerve block patients group (n=20) underwent surgery with two ultrasound-guided regional anaesthesia blocks: a single-shot sciatic nerve block with 20 ml of ropivacaine 0.75% combined with an adductor canal block with a catheter placed for less than 4 days with an infusion of ropivacaine 0.2% at a rate of 6 ml h. LIA patients (LIA group, n=20) received LIA of the knee capsule at the end of surgery with 150 ml of ropivacaine 0.2%. The primary endpoint was postoperative time to patient mobilisation (ability to walk) on the ward. Baseline characteristics were similar in each study group. Patients in both groups were mobilised to walk after TKA in similar time frames (LIA 24.0 h versus nerve block 27.1 h, 95% CI of difference -9.6 to 3.3 h). Maximum postoperative pain scores on exertion were higher in LIA patients with a mean 1.3 of 10 numerical rating scale points (95% CI 0.3 to 2.3, P = 0.010) as were intra-operative opioid requirements (LIA median 107 [IQR 100 to 268] mg versus nerve block median 78 [60 to 98] mg, P < 0.001). Patient satisfaction, postoperative oral morphine-equivalents and resting pain levels were comparable between groups. Anaesthesia induction time was reduced in LIA patients (LIA 10 min versus nerve block 35 min, 95% CI of difference 13 to 38 min, P < 0.001). Both analgesic regimens allow early mobilisation after TKA with high patient satisfaction. LIA shortened peri-operative time. Further research is required to optimise especially pain control during the later postoperative period with LIA. Clinicaltrials.gov identifier NCT03114306.

Regional and Local Anesthesia in Pediatric Orthopaedic Surgery

Objective To compare the safety and efficacy of percutaneous nephrolithotomy (PCNL) performed under local anesthesia (LA). Methods From June 2017 to September 2018, 120 patients with renal stones who underwent percutaneous nephrolithotomy were randomly enrolled into general anesthesia group(n=60) and local anesthesia group (n=60) .The residual stone rate, length of surgery, preoperative anxiety, postoperative hospital stay, hospital costs, postoperative pain and complications in both groups were compared. Results There were statistically significant in preoperative anxiety, postoperative hospital stay, hospital costs, postoperative activity time, postoperative feeding time between the two groups(P<0.05). Conclusions Local anesthesia is feasible and safe in PCNL operations, it has the advantages of quick recovery and low cost. It is worth to be applied. Key words: Urinary Calculi; Nephrostomy, Percutaneous

Background:Bone marrow aspiration and biopsy (BMAB) is a painful procedure, and the commonly adopted local infiltration anesthesia (LIA) with lidocaine is unable to relieve the pain during the most uncomfortable phases, or the anticipatory anxiety related to pain recalling thereafter. As there are no formal guidelines for adding a sedoanalgesic premedication before beginning the BMAB, many combinations have been adopted by several authors.Aims:Our randomized and patient blinded trial aimed to evaluate, as primary end point, the efficacy and safety of opioid and benzodiazepine agent combination plus LIA in patients who underwent BMAB for hematological malignancies. Two secondary end points were: 1) to define if patients who already underwent to BMAB without LIA prefer sedoanalgesia; 2) to demonstrate if sedoanalgesia can influence the quality of the biological specimen harvested.Methods:Patients were randomly assigned into two arms for receiving either placebo plus LIA (standard group, 48,6%) or oral fentanyl citrate 200 mcg + oral midazolam 5 mg in addition to LIA (combo‐group, 51,4%) during BMAB. Pre‐procedural anxiety and procedural pain were assessed according to the Numered Rating Scale (NRS: 0–10), dividing the time of the procedure into five intervals (T0, T1, T2a, T2b, and T3) and evaluating discomfort grade during each moment of procedure in both groups. Cognitive function was measured before and 30 minutes after the procedure. Possible side effects were recorded, as well as the adequacy of tissue samples harvested. A total number 116 patients were enrolled in the study. 9 patients did not meet inclusion criteria and were excluded. 52 patients were randomized and assigned to standard group and 55 to combo group.Results:At T2b and T3 (corresponding to the biopsy time and time after the biopsy, respectively) there was a significantly lower (p &lt; 0.05) perception of pain in the patients who received sedoanalgesia (combo‐group) compared to those who did not (standard group). Moreover, 100 % of the patients in combo group who had previously undergone this procedure without premedication reported that they would prefer sedoanalgesia for the subsequent procedures.Summary/Conclusion:Administration of oral analgesia and anxiolysis is a safe and feasible option to be used in outpatient setting; sedoanalgesia is very effective in reducing pain during the biopsy and it diminishes the anticipatory anxiety related to a painful procedure. Patients should have the possibility to choose between local anesthesia alone or sedoanalgesia plus local anesthesia.

Combined Oral Administration of Analgesia and Anxiolysis for Pain Associated with Bone Marrow Aspiration and Biopsy

ObjectivesTo compare data on transperineal template biopsy (TPTB) under general anesthesia (GA) compared with local anesthesia (LA) procedures using the PrecisionPoint™ Transperineal Access System (PPTAS) in relation to tolerability, cancer detection rate, complications, and cost.MethodsA prospective pilot cohort study of patients undergoing transperineal biopsy was performed. Patients were excluded if they had concurrent flexible cystoscopy or language barriers. Patients had a choice of GA or LA. A prospective questionnaire on Days 0, 1, 7, and 30 was applied. The primary outcome was patient tolerability. Secondary outcomes were cancer detection rate, complication rate, and theater utilization.ResultsThis study included 80 patients (40 GA TPTB and 40 LA PPTAS). Baseline characteristics including age, prostate‐specific antigen (PSA), digital rectal examination (DRE), findings, and prostate volume were comparable between the groups (p = 0.3790, p = 0.9832, p = 0.444, p = 0.3939, respectively). Higher median prostate imaging‐reporting and data system (PI‐RADS) score of 4 (interquartile range [IQR] 2) versus 3 (IQR 1) was noted in the LA group (p = 0.0326). Pain was higher leaving recovery in the GA group however not significantly (p = 0.0555). Median pain score at LA infiltration was 5/10 (IQR 3), with no difference in pain at Days 1, 7, or 30 (p = 0.2722, 0.6465, and 0.8184, respectively). For GA versus LA, the overall cancer detection rate was 55% versus 55% (p = 1.000) with clinically significant cancer in 22.5% versus 35% (p = 0.217). Acute urinary retention (AUR) occurred in 5% of GA and 2.5% of LA patients (p = 1.000). The GA cohort spent longer in theater and in recovery with a median of 93.5 min versus 57 min for the LA group (p = <0.0001).ConclusionThis study demonstrates that transperineal biopsy is safely performed under LA with no difference between the cohorts in relation cancer detection or AUR. LA biopsy also consumed less theater and recovery resources. A further larger prospective randomized controlled trial is required to confirm the findings of this study.

Category: Trauma; Other Introduction/Purpose: Regional anesthesia has been increasingly used within orthopaedic surgery. It has been found to decrease opioid use and consumption and has been associated with decreased blood loss and clot formation in some lower extremity surgeries – specifically hip and knee arthroplasty surgery. General anesthesia is not without risks including malignant hyperthermia, laryngeal edema, vocal cord trauma, and delirium. This has led to increased utilization of regional anesthesia in foot and ankle surgery. However, there is a paucity of research that compares the postoperative outcomes in patients treated with regional compared to general anesthesia in these surgeries. We hypothesize the use of regional anesthesia in foot and ankle surgery leads to fewer short-term postoperative complications compared to general anesthesia. Methods: The American College of Surgeons-National Surgical Quality Improvement Program (ACS-NSQIP) database was queried from 2006-2018 to identify patients undergoing foot and ankle surgery. Current Procedural Terminology (CPT) codes for all foot and ankle surgery were utilized to determine which participants to include in the analysis. The cohort was divided into patients who received regional anesthesia versus those who received general anesthesia, and comparisons were made on demographic characteristics, and comorbidities, using chi-squared and t-test analyses. Multivariate logistic regressions were performed to identify whether lack of regional anesthesia was an independent risk factor for infection, minor postoperative complications, and major postoperative complications. Major postoperative complications included any complication that had a long-term effect on someone’s life or led to reoperation, while minor postoperative complications included any event that needed medical intervention but did not impact a person’s health long-term. Results: Using the ACS-NSQIP database and CPT codes, there were 12,764 participants for regional anesthesia and 73,481 participants who had general anesthesia. Utilizing logistic regression, this study found that the absence of regional anesthesia was independently associated with an increased risk for minor complications in foot and ankle surgery (Odds Ratio (OR) 1.34, 95% Confidence Interval (CI) [1.25-1.44], p=0.00). The absence of regional anesthesia was not associated with increased risk of major complications in foot and ankle surgery (OR 1.04, CI [0.96-1.12], p=0.32). Patients who received regional anesthesia were older and had more comorbidities than those without regional anesthesia used which may be a reason for the findings for major complications. Conclusion: Regional anesthesia independently reduced the risk of minor postoperative complications up to 30-days following foot and ankle surgery in this study. Patients undergoing foot and ankle surgery may benefit from augmenting their anesthetic plan with regional anesthesia.

Nerve blocks have been used for decades at head and neck region interventions and recently introduced as an alternative option for subcutaneous port implantation. This study aimed to compare two different local anesthesia techniques used during subcutaneous port implantation. This retrospective study was conducted with 107 patients who were categorized into two groups according to the local anesthesia techniques used during port implantations. Group 1 underwent local infiltration anesthesia and Group 2 received an ultrasound-guided supraclavicular nerve block. In both groups, prilocaine 2% was used for skin anesthesia and no other systemic anesthetic drugs or additional local anesthetics were administered during port implantation. Local anesthetic doses were 400 mg in Group 1 and 200 mg in Group 2. The time required for adequate cutaneous anesthesia, procedure time, complication rate and visual analog scale (VAS) score were recorded for each patient. Groups 1 and 2 contained 58 and 49 patients respectively. Both groups showed similar demographic distributions of patients (p > 0.05). Mean procedure times and the time required for adequate cutaneous anesthesia were longer in Group 2 (p < 0.05). Group 2 also showed 12 immediate complications, although they were temporary and recovered without any intervention under surveillance. Mean VAS scores during port implantation were similar in both groups [Group 1: 1.17(±0.60), Group 2: 1.1(±0.62)] (p > 0.05). The VAS scores did not differ significantly between groups. Although a supraclavicular nerve block may require lower local anesthetic doses for similar cutaneous anesthesia, it is associated with higher immediate complication rates due to unintended blockade of the peripheral nerves. Thus, if the nerve block is preferred over local infiltration anesthesia during port implantation, to prevent life-threatening complications, caution needed especially for the patients with contralateral vocal cord or diaphragm paralysis.

<h3></h3> The number of spine surgeries being performed has exponentially increased in the last two decades. This rapid growth is mainly attributed to the epidemic of chronic low back pain in developed countries, as well as the introduction of minimally invasive surgical technique that allows more complex spine procedures to be performed safely. Many institutes have protocolized their perioperative management of patients undergoing spine surgery. However, a widely accepted enhanced recovery after surgery (ERAS) pathway for spine surgery has yet to be developed. Early studies suggested ERAS spine protocol enables faster recovery, increase patient satisfaction, reduction of hospital length of stay and healthcare expenditure. There are three major anesthetic considerations for adult patients undergoing complex spine surgery, namely: blood loss, pain management, and position-related complications Complex spine surgery was ranked among the top six most painful procedures. Poor pain control has been shown to be associated with increased risks of wound healing, hospital-acquired infections, length of stay, and delayed mobilization. Pain following spine surgery can result from mechanical irritation, nerve compression, or postoperative inflammatory processes. It can be generated from different structures such as vertebrae, discs, ligaments, muscles, dural sleeves, and capsules of the facet joint. Innervation of these pain generators is from the dorsal rami of spinal nerves. Opioids are commonly used as effective analgesics for the management of severe pain disorders. However, their widespread use is restricted because of their side effects such as nausea, vomiting, and respiratory distress, and acquired tolerance. Preemptive multimodal analgesic regimens that rely on the synergistic action of nonopioid agents given in lower doses have been used to improve postoperative pain management and reduce opioid consumption. Protocols for reducing pain after lumbar surgery recommend the use of regional anesthesia techniques to reduce opioid analgesic use to the minimum. Interfascial plane blocks have the potential to provide extended postoperative analgesia and to reduce opioid consumption and neuraxial-related motor block to a minimum. In order to reduce opioid use, loco-regional and local anesthesia were introduced. In spine surgery, loco-regional techniques were limited to epidural catheters and spinal and epidural morphine. Neuraxial analgesia through spinal opioids or continuous epidural infusion can provide excellent pain control, but these techniques have drawbacks. They can lead to rare but serious complications, such as infection, hematoma, or nerve injury, often cause severe pruritus, nausea, vomiting, and urinary retention, and may cause hypotension in the postoperative period. In addition, the use of central blocks could interfere with neurophysiological monitoring and delay postoperative evaluation of possible neurological complications. Local anesthetic wound infiltration is often performed with unfortunately short-lived effect. With the intention of prolonging the analgesic effect of wound infiltration, the possibility of infiltrating a mixture of local anesthetic, opioid, NSAIDs, and epinephrine in the lumbar region has been postulated. Although the evidence for this practice is limited. In 2020, Jeff L. Xu described a novel regional anesthetic technique in which local anesthetic is deposited around the thoracolumbar dorsal ramus nerve (TDRN) via 4 multiorifice pain catheters placed intraoperatively under direct visualization by the surgeon, Patients who received TDRN block catheters required minimal opiates in the postoperative period and avoided affecting the blockage distribution of ventral ramus nerve and sympathetic chain. This allowed patients to participate in physical therapy as early as on postoperative day 0. This bypassed the potential untoward side effects of epidural analgesia (hypotension, lower extremity weakness, respiratory depression, and urinary retention). In addition, the TDRN block catheters can be used in the upper thoracic spine without fear of respiratory depression and may be used in cases of wide laminectomy or large vertebrectomy. Given the results, the authors believe that a larger study comparing TDRN block catheters with the standard thoracic or lumbar epidural or other regional approaches should be performed in the setting of a multimodal analgesic regimen. The loco-regional technique used in this type of surgery should aim to anaesthetize the dorsal root of the spinal nerves at the appropriate operative level. Dorsal ramus blocks have been shown to be feasible in the treatment of chronic pain. In a recent series of case reports, a bilateral block of the lumbar dorsal ramus nerve showed improved pain scores and reduced morphine consumption after spine surgery A loco-regional technique suitable for back surgery should cover the innervation of the relevant vertebrae and paravertebral muscles and include the dorsal roots of the spinal nerves at this level. The Toracolumbar interfascia plane (TLIP) block was first described by Hand et al. In the TLIP block, local anesthetic agents are injected into the fascial plane lying between the multifidus and longissimus muscles at the level of the third lumbar vertebra, targeting the posterior rami of the thoracolumbar spinal nerves, thus achieving a reproducible area of anesthesia with a predictable spread. The TLIP block can provide effective postoperative analgesia for lumbar spine surgery, decrease postoperative VAS scores, and reduce opioid consumtion after lumbar spine surgery. In addition, the TLIP block significantly reduces the side effects of nausea. However, further studies are needed to testify these benefits, and more high-quality RCTs are still necessary and urgently required for further research. Ultrasound-guided erector spinae plane blockade (ESP) was first developed by Forero in 2016 as an easy, safe way of managing thoracic neuropathic pain.Since that time, this block has gained in popularity and has been used to effectively provide analgesia for a variety of surgeries, including spine surgery. Theoretically, an infiltration between the erector spinae muscle and the transverse process provides anesthesia of the dorsal ramus at the same vertebral level. Since the local anesthetic is injected into a plane, the solution can spread both caudally and cranially via the toracolumbar fascia, resulting in anesthesia of the dorsal ramus of the spinal nerves above and below the injected level. Potential benefits of the lumbar ESP include the ease of performance with clear landmarks for ultrasound anatomy. The technique is inherently safe, as the target site for injection is a muscular plane and there is practically no risk for mechanical nerve contact. Other benefits include the possible reduction in perioperative opioid consumption. The ESP is performed in patients under anticoagulant therapy or with coagulopathies. Furthermore, hemodynamic instability due to sympathetic blockade, as with epidural and spinal anesthesia, occurs rarely. Possible risks consist primarily of local anesthetic systemic toxicity. Since substantial doses are considered necessary, there is a clinically significant risk for local anesthetic systemic toxicity, as with any high-volume fascial block. For this reason, patients need to be monitored according to American Society of Regional Anesthesia guidelines with Intralipid available at all times. Some meta-analysis demonstrates that ESP is effective in reducing postoperative pain intensity and postoperative opioid consumption in spine surgery. Furthermore, ESP is easy to perform and has few complications. Therefore, for the management of postoperative pain following spine surgery, preoperative ESP is a good choice. More studies are still needed in order to explore doce. Both the ESPB and TLIP blocks have shown to provide adequate analgesia after lumbar spinal surgery. Clinicians can choose either the TLIP block or the ESPB for pain control after lumbar spinal surgery based on their clinical experience and choice. Currently there is no consensus as to the superiority of one over the other. Retrolaminar block (RLB) was first reported in 2006 as an alternative approach to PVB. RLB is performed with US imaging or the landmark technique. The needle is inserted at a puncture site 1–1.5 cm lateral to the target spinous process and advanced caudally or cranially until it contacts the lamina. Local anesthetics are injected on the lamina at doses of 20–30 ml. RLB can be performed with the US-guided, in-plane insertion technique. The sagital plane with a linear US probe allows for visualization of the laminae or transversus process, and the needleis advanced using the in-plane technique. The retrolaminar block has been successfully used in spinal surgery, although the large number of publications that we have on the ESP block have left this approach relegated. Although everything indicates that regional techniques will be a fundamental pillar in ERAS protocols for spinal surgery, there is no consensus regarding which is the best technique to control postoperative pain in these patients. More studies are needed to reach definitive conclusions in this regard. <h3>References</h3> Abdulrahman Alboog , Sandy Bae, Jason Chui.

Previous studies have shown that regional anesthesia (RA) use versus placebo control is associated with less postsurgical opioid requirements and improved pain scores. This trial compared a novel combination of bilateral pecto-intercostal fascial plane and unilateral rectus sheath blocks to an active comparator of surgeon-administered local anesthetic wound infiltration in children undergoing septal defect repair. The study tested the hypothesis that RA use would result in less opioid use and lower pain intensity compared to wound infiltration. This double-blind, randomized, parallel group, single-center trial included children (<18 years) undergoing primary atrial septal defect (ASD) or ventricular septal defect (VSD) repair. Participants were randomized to RA consisting of ultrasound-guided pecto-intercostal fascial plane and rectus sheath blocks or no-block, consisting of local anesthetic wound infiltration. Both groups received 1.5 mL/kg of ropivacaine 0.2% for the intervention. The primary outcome was opioid use (oral morphine milligram equivalents [MME]/kg) 0-12 hours after surgery. Secondary outcomes were opioid use at additional time points, pain (0-10 scale) between 0 and 48 hours (area under the curve [AUC]), and hospital length of stay (LOS). Data analysis included 42 children (24 RA, 18 infiltration), age 3.3 ± 2.7 years (mean ± standard deviation [SD]; median, 3; range, 4 months-10 years). Opioid use (MME/kg mean ± SD) 0-12 hours after surgery was 0.44 ± 0.19 in the RA group compared to 0.83 ± 0.39 in the infiltration group (mean difference -0.39; 95% confidence interval [CI], -0.59 to -0.18; P = .001). Total postoperative opioid use from 0 to 48 hours after surgery was 0.95 ± 0.40 in the RA group compared to 1.57 ± 0.75 in the infiltration group (mean difference -0.64; 95% CI, -1.02 to -0.22, P = .004). Pain intensity AUC (0-48 hours) was 45.0 ± 26.8 in the RA group compared to 94.5 ± 55.7 in the infiltration group (mean difference -49.5 [-78.9 to -20.1]; P = .002). Opioid use between 12 and 48 hours and hospital LOS was not different between groups. This single-center study showed that the combined pecto-intercostal fascial plane and rectus sheath blocks were opioid-sparing and provided superior pain control compared to contemporary practice of local anesthetic infiltration in children following septal defect repair. This investigation strengthens the evidence to support RA use to improve postoperative pain in this population.
