Determination of parents' sense of security after spontaneous vaginal delivery and cesarean section.

Stress urinary incontinence (SUI) in young women is usually the result of pelvic floor injury during vaginal delivery. Whether cesarean section delivery may prevent such injury is questionable. We undertook a prospective study to compare the prevalence of SUI among primiparae 1 year after spontaneous vaginal delivery versus elective cesarean section, or cesarean section performed for obstructed labor. Three hundred and sixty-three consecutive primiparae were recruited immediately after delivery and were followed for 1 year. Women were asked upon recruitment whether they had ever experienced SUI before pregnancy. Those who had SUI before pregnancy were excluded. Thus, only cases of de novo childbirth-associated SUI were analyzed. Patients were divided into three subgroups according to the mode of delivery: spontaneous vaginal delivery (n = 145), elective cesarean section (n = 118), and cesarean section performed for obstructed labor (n = 100). Patients who underwent elective cesarean section were not given a trial of labor. Cesarean sections for obstructed labor were performed at a mean cervical dilatation of 8.7 +/- 1.6 cm and arrest of 184 +/- 24 min. Prevalence, frequency, and severity of postpartum SUI, as well as demographic and obstetric parameters, were analyzed in each subgroup. The three subgroups were comparable with respect to maternal age, weight, and height. Prevalence of postpartum SUI was similar after spontaneous vaginal delivery (10.3%) and cesarean section performed for obstructed labor (12%). However, SUI was significantly less common following elective cesarean section with no trial of labor (3.4%, P < 0.05). Approximately half of the symptomatic patients in each subgroup reported either moderate or severe symptoms, however, only 15-18% expressed their desire for further evaluation. Prevalence of postpartum SUI is similar following spontaneous vaginal delivery and cesarean section performed for obstructed labor. It is quite possible that pelvic floor injury in such cases is already too extensive to be prevented by surgical intervention. Conversely, elective cesarean section, with no trial of labor, was found to be associated with a significantly lower prevalence of postpartum SUI. Whether the prevention of pelvic floor injury should be an indication for elective cesarean section is yet to be established.

ObjectiveWe compared birth injuries for spontaneous vaginal (VD) and caesarean section (CS) deliveries in preterm and term pregnancies.MethodsA retrospective cohort study was conducted in a single tertiary center, between January 1st, 2007, and December 31st, 2017. The study included 62330 singleton pregnancies delivered after 24 0/7 weeks gestation. Multivariable analyses compared trauma at birth, birth hypoxia and birth asphyxia in term and preterm deliveries, stratified by mode of birth, VD versus CS. Main outcome measure was trauma at birth including intracranial laceration and haemorrhage, injuries to scalp, injuries to central and peripheral nervous system, fractures to skeleton, facial and eye injury.ResultsThe incidence of preterm deliveries was 10.9%. Delivery of preterm babies by CS increased from 37.0% in 2007 to 60.0% in 2017. The overall incidence of all birth trauma was 16.2%. When stratified by mode of delivery, birth trauma was recorded in 23.4% of spontaneous vaginal deliveries and 7.5% of CS deliveries (aOR 3.3, 95%CI 3.1–3.5). When considered all types of birth trauma, incidence of trauma at birth was higher after 28 weeks gestation in VD compared to CS (28–31 weeks, aOR 1.7, 95% CI 1.3–2.3; 32–36 weeks, aOR 4.2, 95% CI 3.6–4.9; >37 weeks, aOR 3.3, 95% CI 3.1–3.5). There was no difference in the incidence of birth trauma before 28 weeks gestation between VD and CS (aOR 0.8, 95% CI 0.5–1.2). Regarding overall life-threatening birth trauma or injuries at birth with severe consequences such as cerebral and intraventricular haemorrhage, cranial and brachial nerve injury, fractures of long bones and clavicle, eye and facial injury, there was no difference in vaginal preterm deliveries compared to CS deliveries (p > 0.05 for all).ConclusionCS is not protective of injury at birth. When all types of birth trauma are considered, these are more common in spontaneous VD, thus favoring CS as preferred method of delivery to avoid trauma at birth. However, when stratified by severity of birth trauma, preterm babies delivered vaginally are not at higher risk of major birth trauma than those delivered by CS.

Background: Pregnant women have difficulty deciding on birth methods because many factors influence the choice.This study described the factors influencing pregnant women's preferred method of birth in a tertiary health care facility in Ghana.Methods: This descriptive cross-sectional study used a systematic sampling method to select 222 pregnant women who sought antenatal services at the Ho Teaching Hospital to respond to a pre-tested questionnaire.The data was entered into Epi info version 3.1 and transferred to STATA version 15.1 for analysis.Data were summarized into descriptive statistics and analyzed using the 2 association test. Results:The results showed that 50.5% of the pregnant women had previously had a spontaneous vaginal delivery (SVD), 16.2% had cesarean section (CS), 5.9% had both CS and SVD, and 27.5% were first-time pregnant women.There was a significant (P-value 0.00, 2 = 27.95) relationship between the birth experiences and preferred birth methods of pregnant women, as those who have a history of SVD will prefer the same (58.0%).Also, those who previously had a CS will prefer the same method (52.2%).There was a significant association (P-value 0.04, 2 = 3.39) between the choice of delivery and respondent's parity.SVD was chosen by nulliparous (34.2%), para one (28.6%),and grand multipara (10.6%).Conclusion: The women's preferred choice for birth is primarily influenced by their previous experience of delivery, and the higher the parity, the likelihood of choosing SVD for subsequent childbirth.Pregnant women need to be educated more on the different methods of birth and the health benefits of midwives during antenatal so that they can make informed choices for their subsequent childbirth.

Maternal CD4 + microchimerism in HIV-exposed newborns after spontaneous vaginal delivery or caesarean section

Vaginal delivery refers to the birth of offspring in mammals or babies in humans, through the vagina, also known as the “birth canal”. It is the natural method of birth for most mammals excluding those which lay eggs. For women who deliver vaginally, childbirth progresses in three stages: labor, delivery of the baby and delivery of the placenta. There are two types of vaginal delivery: Unassisted vaginal delivery and assisted vaginal delivery. In the later, this assistance can vary from use of medicines to emergency delivery procedures. The following types of vaginal delivery have been noted; (a) Spontaneous vaginal delivery (SVD) (b) Assisted vaginal delivery (AVD), also called instrumental vaginal delivery (c) Induced vaginal delivery and (d) Normal vaginal delivery (NVD), usually used in statistics or studies to contrast with a delivery by cesarean section. Delivery of a full-term newborn occurs at a gestational age of 37–42 weeks, usually determined by the last menstrual period or ultrasonographic dating and evaluation. Nearly 80% of newborns are delivered at full term while approximately 10% of singleton pregnancies are delivered preterm and 10% of all deliveries are post-term.

BackgroundPublic hospitals in developing countries, rather than the preventive and primary healthcare sectors, are the major consumers of healthcare resources. Imbalances in rational, equitable and efficient allocation of scarce resources lie in the scarcity of research & information on economic aspects of health care. The objective of this study was to determine the average cost of a spontaneous vaginal delivery and Caesarean section in a tertiary level government hospital in Islamabad, Pakistan and to estimate the out of pocket expenditures to households using these services.MethodsThis hospital based cost accounting cross sectional study determines the average cost of vaginal delivery and Caesarean section from two perspectives, the patient's and the hospital. From the patient's perspective direct and indirect expenditures of 133 post-partum mothers (65 delivered by Caesarean section & 68 by spontaneous vaginal delivery) admitted in the maternity general ward were determined. From the hospital perspective the step down methodology was adopted, capital and recurrent costs were determined from inputs and cost centers.ResultsThe average cost for a spontaneous vaginal delivery from the hospital's side was 40 US$ (2688 rupees) and from the patient's perspective was 79 US$ (5278 rupees). The average cost for a Caesarean section from the hospital side was 162 US$ (10868 rupees) and 204 US$ (13678 rupees) from the patient's side. Average monthly household income was 141 ± 87 US$ for spontaneous vaginal delivery and 168 ± 97 US$ for Caesarean section. Three fourth (74%) of households had a monthly income of less than 149 US$ (10000 rupees).ConclusionThe apparently "free" maternity care at government hospitals involves substantial hidden and unpredicted costs. The anticipated fear of these unpredicted costs may be major factor for many poor households to seek cheaper alternate maternity healthcare.

Prospective Randomized Trial of Cesarean Delivery versus Vaginal Delivery for Effects on the Pelvic Floor in Squirrel Monkeys

Objective:To analyse the factors associated with Caesarean Section (CS) of Nulliparous, Term and Singleton pregnancies with Vertex presentation (NTSV) at a tertiary care hospital.Methods:In this unmatched retrospective case-control study, 212 NTSV patients were identified through computerized medical record systems; the data was collected through predesigned Performa by reviewing medical record charts. One hundred six CS and spontaneous vaginal deliveries (SVD) were taken as cases and controls.Results:The mean maternal age of cases (CS) was 26.64 (SD: 3.9) and of controls (SVD) was 26.7(SD: 3.9) years, whereas mean gestational age was 38.66±1.12 and 38.57±0.9 weeks for cases and controls respectively. Ninety per cent of women in the study group were delivered within 10 hours of active labour. Babies that weighed ≤3kg were 45% and >3kg were 55%. The possibility of being high risk was twice more among those delivered by CS. However, it was not statistically significant (p value 0.077). Labour was induced in 38% patients. The Odds of Induction of Labour (IOL) were two times more and delivering at night was three times more amongst CS. The likelihood of labour exceeding 10 hours was four times (81%) if the patient had a CS. Moreover 48% of the babies weighing >3kg were delivered through CS. Maternal age, high risk pregnancies, gender of baby and epidural analgesia were not statistically significant predictors of mode of delivery (MOD) in this study.Conclusion:Induction of Labour, night time delivery, prolonged labour and birth weight <3kg were found to be associated with the increased CS rate among NTSV. Therefore further research is required in order to address these factors and to reduce the increasing Caesarean Section.

The rate of obstetric anal sphincter injury has increased in recent years, particularly among operative vaginal deliveries. We sought to characterize temporal trends in episiotomy use and to quantify the association between episiotomy and obstetric anal sphincter injury. Using a population-based retrospective cohort study design of hospital data from 2004 to 2017, we studied all vaginal deliveries of singleton infants at term gestation in Canada (excluding Quebec). Rates of obstetric anal sphincter injury were contrasted between women who had an episiotomy and those who did not. Log-binomial regression was used to estimate the association between episiotomy and obstetric anal sphincter injury among women with spontaneous and operative vaginal deliveries after controlling for confounders. The study population included 2 570 847 deliveries. Episiotomy use declined significantly among operative vaginal deliveries (53.1% in 2004 to 43.2% in 2017, p < 0.0001) and spontaneous vaginal deliveries (13.5% in 2004 to 6.5% in 2017, p < 0.0001). Episiotomy was associated with higher rates of obstetric anal sphincter injury among spontaneous vaginal deliveries (4.8 with episiotomy v. 2.4% without; adjusted rate ratio [RR] 2.06, 95% confidence interval [CI] 2.00-2.11) and this association remained after stratification by parity and obstetric history. In contrast, episiotomy was associated with lower rates of obstetric anal sphincter injury among forceps deliveries in nulliparous women (adjusted RR 0.63, 95% CI 0.61-0.66), and women with vaginal birth after cesarean (adjusted RR 0.71, 95% CI 0.60-0.85), but not among parous women without a previous cesarean (adjusted RR 1.16, 95% CI 1.00-1.34). Episiotomy use has declined in Canada for all vaginal deliveries. The protective association between episiotomy and obstetric anal sphincter injury among women who gave birth by operative vaginal delivery (especially forceps) warrants reconsideration of clinical practice among nulliparous women and those attempting vaginal birth after cesarean.

Does a primary Caesarean section influence the rate of, and time to, subsequent live birth compared with vaginal delivery? Caesarean section was associated with a reduction in the rate of subsequent live birth, particularly among elective and maternal-requested Caesareans indicating maternal choice plays a role. Several studies have examined the relationship between Caesarean section and subsequent birth rate with conflicting results primarily due to poor epidemiological methods. This Danish population register-based cohort study covered the period from 1982 to 2010 (N = 832 996). All women with index live births were followed until their subsequent live birth or censored (maternal death, emigration or study end) using Cox regression models. In all 577 830 (69%) women had a subsequent live birth. Women with any type of Caesarean had a reduced rate of subsequent live birth (hazard ratio [HR] 0.86, 95% confidence intervals [CI] 0.85, 0.87) compared with spontaneous vaginal delivery. This effect was consistent when analyses were stratified by type of Caesarean: emergency (HR 0.87, 95% CI 0.86, 0.88), elective (HR 0.83, 95% CI 0.82, 0.84) and maternal-requested (HR 0.61, 95% CI 0.57, 0.66) and in the extensive sub-analyses performed. Lack of biological data to measure a woman's fertility is a major limitation of the current study. Unmeasured confounding and limited availability of data (maternal BMI, smoking, access to fertility services and maternal-requested Caesarean section) as well as changes in maternity care over time may also influence the findings. This is the largest study to date and shows that Caesarean section is most likely not causally related to a reduction in fertility. Maternal choice to delay or avoid childbirth is the most plausible explanation. Our findings are generalizable to other middle- to high-income countries; however, cross country variations in Caesarean section rates and social or cultural differences are acknowledged.

Congenital nasolacrimal duct obstruction (dacryostenosis) with a persisting membrane at Hasner's valve is the most common cause of persistent tear and ocular discharge in infants. To evaluate whether there is an association between congenital dacryostenosis and delivery via cesarean section. In a prospective study we examined 107 children (mean age 9.2 ± 7.1 months) with congenital dacryostenosis. We evaluated data about the mode of delivery (vaginal delivery versus cesarean section) and gestational age at the time of birth. Within the first 8 months of life children were treated by probing using local anesthesia, whereas older children were treated using general anesthesia. After the age of 11 months treatment included nasolacrimal duct intubation with a bicanalicular stent. Statistical analyses were performed using binomial tests, Fisher's exact test and the t-test. In this study 51 children delivered by cesarean section were compared with 56 children delivered by spontaneous vaginal delivery. A total of 44 age-matched pairs from both groups were evaluated in order to eliminate confounding factors due to gestational age at delivery. Based on the published rate of cesarean sections from the same region of the State of Hesse between 2002-2004 we observed a statistically significant association between congenital dacryostenosis and delivery by cesarean section among the 88 age-matched patients (P = 0.009). Moreover, subgroup analysis revealed a significant association between congenital dacryostenosis and delivery by primary cesarean section (P = 0.00004). The prevalence of surgical treatment was not statistically different between both groups based on the mode of delivery (P = 0.8). Our results suggest that delivery via cesarean section is associated with a significantly higher prevalence of congenital dacryostenosis.

BackgroundFew studies have focused on cerebral complications among newborn infants delivered by vacuum extraction (VE). The aim of this study was to determine the risk for intracranial haemorrhage and/or cerebral dysfunction in newborn infants delivered by VE and to compare this risk with that after cesarean section in labour (CS) and spontaneous vaginal delivery, respectively.MethodsData was obtained from Swedish national registers. In a population-based cohort from 1999 to 2010 including all singleton newborn infants delivered at term after onset of labour by VE (n = 87,150), CS (75,216) or spontaneous vaginal delivery (n = 851,347), we compared the odds for neonatal intracranial haemorrhage, traumatic or non-traumatic, convulsions or encephalopathy. Logistic regressions were used to calculate adjusted (for major risk factors and indication) odds ratios (AOR), using spontaneous vaginal delivery as reference group.ResultsThe rates of traumatic and non-traumatic intracranial hemorrhages were 0.8/10,000 and 3.8/1,000. VE deliveries provided 58% and 31.5% of the traumatic and non-traumatic cases, giving a ten-fold risk [AOR 10.05 (4.67-21.65)] and double risk [AOR 2.23 (1.57-3.16)], respectively. High birth weight and short mother were associated with the highest risks. Infants delivered by CS had no increased risk for intracranial hemorrhages. The risks for convulsions or encephalopathy were similar among infants delivered by VE and CS, exceeding the OR after non-assisted spontaneous vaginal delivery by two-to-three times.ConclusionVacuum assisted delivery is associated with increased risk for neonatal intracranial hemorrhages. Although causality could not be established in this observational study, it is important to be aware of the increased risk of intracranial hemorrhages in VE deliveries, particularly in short women and large infants. The results warrant further studies in decision making and conduct of assisted vaginal delivery.

Blood transfusions associated with mode of delivery, risk factors for postpartum hemorrhage, and antepartum anemia, during hospital admissions for delivery

PurposeTo examine the association between mode of delivery (in particular caesarean section) and behavioural outcomes in offspring at six time-points between age 3 and 17 years.MethodsSimilar to previous work examining the association between mode of delivery and behavioural outcomes in offspring at age 7, we used maternal-reported data from the Millennium Cohort Study. Data on mode of delivery were collected when children were 9 months and categorised as spontaneous vaginal delivery, assisted vaginal delivery, induced vaginal delivery, emergency caesarean section, planned caesarean section and caesarean section after induction of labor. Data on behavioural outcomes were collected at ages 3, 5, 7, 11, 14 and 17 years using the Strengths and Difficulties Questionnaire (SDQ). Crude and adjusted logistic regression examined mode of delivery–behavioural difficulties relationship, using validated SDQ cut-off points (total SDQ ≥ 17, emotional ≥ 5, conduct ≥ 4, hyperactivity ≥ 7, peer problems ≥ 4 and prosocial behaviour ≤ 4). Multilevel models with linear splines examined the association between mode of delivery and repeated measures of SDQ.ResultsThere were 18,213 singleton mother–child pairs included at baseline, 13,600 at age 3; 13,831 at age 5; 12,687 at age 7; 11,055 at age 11; 10,745 at age 14 and 8839 at age 17. Adjusted logistic regression suggested few associations between mode of delivery and behavioural outcomes at ages 3, 5, 11, 14 and 17 years using validated SDQ cut-off points. After correction for multiple testing, only the protective association between planned caesarean section-Conduct difficulties at age 5 years (OR 0.63, 95% CI 0.46, 0.85) and positive association between caesarean section after induction-Emotional difficulties at age 11 years (OR 1.57, 95% CI 1.19, 2.07) remained statistically significant. Multilevel modelling suggested mean SDQ scores were similar in each mode of delivery group at each time point.ConclusionsResults of this study indicate that mode of delivery is unlikely to have a major impact on behavioural outcomes.

Delivery outcomes and events in subsequent pregnancies after previous anal sphincter injury
