ABSTRACT
Background: Preterm delivery is a major cause of neonatal mortality and morbidity. Various modalities have been used to prediction of patient at risk of preterm labor. But due to multi-factorial etiology these predictors are not always useful. Tocolysis has a major role in arresting preterm labor. The purpose of this study was to compare the safety and efficacy of oral nifedipine with transdermal nitroglycerine in the inhibition of preterm labour.Methods: This single blinded randomized control trial was conducted in the labour room of department of Obstetrics and Gynecology from January 2011 to June 2012. One hundred women with singleton pregnancy between 28 weeks to 34 weeks preterm labour and no contraindication for tocolysis were enrolled in the study. After taking the informed consent subjects were randomized into two groups. Randomization was done by random number table. Fifty-one subjects in nifedipine group received oral nifedipine (Tab Depin 10mg). Forty-nine subjects receiving transdermal nitroglycerine patch (Nitroderm Patch 10) were included in NTG group. The variables analysed were delay in delivery for 48 hours, 7 days or more than 7 days, period of gestation at delivery and side effect profile of drugs.Results: The percentage of women delivering after 48hours of administration of nifedipine group (52.9%) and nitroglycerine group (53.1%). Failure of tocolysis, defined as delivery within 48 hours, with nitroglycerine group (32.7 %) was comparable to nifedipine (33.3 %). Headache was significantly higher in nitroglycerine group as compared to nifedipine group (p≤0.001). Maternal tachycardia was more common in nifedipine group compared to NTG group (p=0.001).Conclusions: Oral nifedipine and transdermal nitroglycerine have similar efficacy as tocolytic agent in patients with preterm labour.
ABSTRACT
Objectives: To evaluate the clinical, behavioral and health-care associated risk factors of intrapartum perinatal mortality (IPPM). Design: Prospective cohort study. Setting: Labor room and postnatal wards of a teaching hospital in North India. Participants: Pregnant women were eligible for enrolment in the study if period of gestation at delivery was 35 weeks or more or baby weighed at least 2000 g at birth, index pregnancy was not booked in antenatal clinic of the study hospital and fetus was delivered within 24 h of admission in the hospital. Methods: Information about antenatal care and events surrounding labor and delivery were retrieved from antenatal care records, referral notes, hospital clinical records and interview of mothers. Multivariate analysis was conducted using forward stepwise logistic regression analysis. Main Outcome Measure: IPPM was defined as asphyxiaspecific stillbirth or asphyxia-specific early neonatal death. Results: Among 248 emergency obstetric referrals during the study period, rate of IPPM was 8% (20/248, 18 fresh stillbirths and 2 asphyxia-specific neonatal deaths). District hospitals and community health-centers/first referral units contributed threefourths of all referrals. On logistic regression analysis significant risk factors for IPPM were presence of obstructed labor (OR: 23, 95% CI: 1.9-275.8), father engaged in unskilled labor (OR: 10, 95% CI: 1.3-77.7) and absence of urine examination during antenatal period (OR: 5.5, 95% CI: 1.8-16.3). Conclusions: Low socioeconomic status, inadequate antenatal care and poor intrapartum care due to unskilled birth attendance are risk factors of IPPM.
