“…Studies done in other settings have recommended the use of maternal height cut offs of <155.5 cm [20], and <162.5 cm [23] for African mothers. Table 4 shows that increasing the maternal height cut off to the ROC optimum cut off of <160.4 cm improves the sensitivity of the test while increasing the false positive rate.…”

“…All simulations for the ROC analysis were done up to 1000 times using the bootstrapping procedures. During analysis, cut off values were generated as part of the ROC analysis with added comparisons with values from literature for maternal weight, maternal pelvis height [22] and maternal height [20, 23]. No distinction was made between normal vaginal and instrumental vaginal deliveries that were grouped together, during analysis, as a single outcome measure, vaginal delivery.…”

BackgroundBirth related newborn and maternal mortality/morbidity remains high in most of sub-Saharan Africa compared to the rest of the world. In this low income region there is a need for valid, low cost, easy to use mass screening tests. This study looked at the screening value of maternal: height, weight and pelvis height, for assessing the outcomes of parturition in Ugandan mothers at term.MethodsThis was a multi site cross-sectional study on mothers with singleton pregnancies in labour at various hospitals in different parts of Uganda. A summary of the details of the pregnancy, maternal height, weight and the delivery record were captured and analysed to generate descriptive and inferential (multilevel logistic regression analysis) and diagnostic (Receiver Operator Curve analysis) statistics.ResultsWe recruited 1146 mothers from all the study sites during the study period of whom 987 (86.13%) had normal deliveries and healthy babies. Mothers with adverse outcomes included 107 mothers that had caesarean section and 52 mothers who had vaginal deliveries with foetal Apgar score of ≤7 at 5 min of whom 11 had fresh still births. Maternal height (Adj OR 0.97, 95% CI 0.94–1.00) and maternal pelvis height (Adj OR 0.73, 95% CI 0.61–0.86) were significantly associated with adverse pregnancy outcomes. The combination of maternal: height (<150 cm), weight (>55.7 kg) and pelvis height (>8.95 cm) had the best diagnostic value with a combined area under the curve of 0.60.ConclusionsIt was observed that an increase in either maternal pelvis height or maternal height was associated with a significant reduction in adverse pregnancy outcomes. The cut off values of all three evaluated maternal anthropometric measurements were of low test accuracy as screening tests even when used together. Further research is needed to develop low cost screening tools for use in low income settings.

“…The decision depends on many factors like the Cephalopelvic Disproportion (CPD), Deep Transverse Arrest (DTA), and sometimes fetal distress, poor maternal effort and prophylactic application of instruments but the clinical judgment here has to be prudent. [8][9][10] Failure of judgment may leads to grave maternal and neonatal morbidity or mortality. Numerous studies have been documented where emergency CS was performed as first line intervention for second stage rather than ID.…”

Introduction Managing second stage of labour is very crucial. Emergency Cesarean Section (CS) or Instrumental Delivery (ID) is the only choices although complications might occur in both modes of deliveries. The rate of CS is at rise and the fear of failed ID followed by emergency CS with added complications makes the choice more difficult amongst the obstetricians. MethodsA retrospective study done to assess the maternal and fetal outcome in second stage of labour following ID and emergency CS from April 2018 to March 2019 among the pregnant women having completed 34 weeks of gestations and beyond. ResultsOf 4761 deliveries, 2537 (53.2%) were vaginal and 2224 (46.7%) CS, and amongst all, 133 (2.7%) were second stage interventions. Out of 133, 78 had ID, 76 were successful and 2 failed. Fifty seven (2.6%) were second stage CS. Nulliparas (65.8%) needed more ID, teenage pregnancy (6.5%) (p=0.04) and heart disease (18.4%) (p=0.002) were high risk for ID. Complications were more in CS, uterine extensions, (29.8%) (p<0.001), urinary complications, (43.9%) (p<0.001) and blood loss (p<0.001). Neonatal admission too was higher in CS (n=29) and more so due to respiratory distress (16/29). ConclusionDespite of few failed attempted ID, it still proved to be better choice for delivery during second stage, as both maternal and neonatal complications were higher following the second stage CS. Hence, the correct and timely decision for ID addressing the associated risk factors could lead to favorable outcome.

“…Although several studies have been done to compare the prevalence of maternal and neonatal morbidity and mortality between second-stage CS and ID, (12) similar data is limited in the Asian population, where maternal height and pelvic dimensions, which influence the likelihood of cephalopelvic disproportion (CPD), are significantly different. (13)(14)(15) These differences are an important consideration, as a clinical diagnosis of CPD precludes the use of ID, hence influencing the rates of IDs and second-stage CSs. Additionally, no randomised controlled trial has been carried out to compare the outcomes of both types of interventions.…”

More than one out of four parturients requiring intervention for prolonged second stage underwent emergency CS. Low failed instrumentation rates and larger babies in the CS group suggest accurate diagnosis of cephalopelvic disproportion. Higher incidence of CS after hours suggests trainee reluctance to attempt ID. There were no clinically significant differences in maternal and neonatal morbidity.
