Obstetric and perinatal outcomes of expectant management and immediate induction of labour in term premature rupture of membranes: promising outcomes from expectant management cohort

Background: Premature rupture of membranes (PROM) is common obstetric entity, the management even at term is controversial and there is no consensus for definite protocol of management. Objective of the present study is to compare the effectiveness, safety of expectant management of 24 hours and immediate induction with PGE2 gel in terms of maternal and fetal outcome in term PROM.Methods: 200 women were randomized to group A expectant management and group B immediate induction, after strict Inclusion and exclusion criteria. In expectant group waiting period was 24 hours. Multiple end points were examined throughout management. Chi square test and independent t tests were performed for statistical analysis. P value<0.05 was considered significant.Results: Demographic parameters of patients, maternal and gestational age were similar in both groups. Primigravidae were more in both groups A and B. Vaginal delivery rate is more in expectant group and Caesarean Section rate is high in immediate induction group. CS rate was 37% and 23% in group A and B respectively; the difference is statistically significant (p value=0.031). ‘ROM to delivery interval’ was more in group A (16.31±8.67 hrs and 13.85±5.46 hrs) (p value=0.0256). Hospital stay was comparatively more in group A (5.40±0.81 days and 4.11±0.86 days) (p value=0.435). Infective morbidity of mother and baby was low in both groups and no difference was seen.Conclusions: An expectant management allows a good number of women to go into labour and deliver vaginally without an increase in CS rate and infectious morbidity for mother and fetus

A prospective, randomized, cross sectional study of manual versus vacuum extraction of mobile head in caesarean section

Background: Considering the high rate of caesarean section, and the difficulty during delivery of the floating foetal head even by the most experienced obstetrician, the use of vacuum has been described. The present study was undertaken with the hypothesis that, vacuum assisted foetal head delivery during caesarean section is safe and effective without increasing maternal and neonatal complications. The outcomes enumerated by the limited literature available need to be evaluated before it is used routinely.Methods: A prospective, randomized, comparative, cross sectional Hospital based study was conducted at St. Philomena’s Hospital, Bangalore. Every woman randomized for the study received either conventional method or ventouse extraction of fetal head at cesarean section. 200 women were enrolled into the study with 100 in each arm. The primary outcome measures were percentage of successful extractions and I-D interval. The secondary outcome measures were, uterine incision extension, estimated blood loss, Apgar scores, neonatal hyperbilirubinemia and neonatal scalp or head injury.Results: Successful extraction was done in 89 % and 98 % cases in manual and vacuum extraction cases. (p =0.0184). U-D interval in the manual extraction group was 66.59±4.64 seconds and in the Vacuum extraction group it was 56.06±3.46 seconds (P&lt;0.001). The mean pre-delivery hemoglobin levels in group I was 11.6±0.73 compared to 11.36±0.49 gm% in group II. The mean post-delivery hemoglobin levels in group I was 10.29±0.79 compared to 10.21±0.53 gm% in group II (p &lt;0.001). The uterine incision extensions were significantly higher in manual extraction group, 18 of the 100 women (18 %), whereas only 2 of the 100 women in vacuum group had uterine extensions (p=0.0002).Conclusions: Authors conclude that the routine use of ventouse is safe and effective for mobile fetal head extraction at cesarean section

A study of cardiovascular autonomic function in normal pregnancy

Objective: The present study was designed to evaluate the physiological responses to noninvasive cardiovascular autonomic function tests in normal pregnancy and compare them with non- pregnant controls. Materials and Methods: The study population comprised of 90 apparently healthy, pregnant women divided equally into three groups based on their period of gestation and 30 otherwise healthy, non-pregnant women as controls. The standard autonomic function tests based on cardiovascular reflexes, including heart rate response tests and blood pressure response tests were performed. Result: It was observed that variability of mean between and within all the population groups and controls was significantly different. Multiple comparison analysis revealed a significantly lower Deep Breathing Difference in pregnant subjects, significant difference in Valsalva Ratio in third trimester group, a significantly lower Postural Tachycardia Index only during last trimester and a significantly higher fall in systolic blood pressure on standing only during 1st trimester. A significantly lower alteration in diastolic blood pressure during isometric handgrip in later trimesters and a significant increase in overall cardiovascular autonomic score between and within all groups were also observed. Conclusion: The observations serve to corroborate that the cardiovascular indices in pregnant women are significantly altered in comparison to non-pregnant women, thus highlighting the importance of cardiovascular monitoring during pregnancy. The study also helped to reaffirm the efficacy of simple cardiovascular reflex tests in research on pregnancy physiology
