Abstract

OBJECTIVES: To study the various fetomaternal outcomes of referred cases of preterm labour beyond 30 weeks To study the clinical profile of referred cases of preterm labour beyond 30 weeks METHODS: A cross-sectional study was done on all cases of preterm labour, referred to SAT Hospital beyond 30 weeks for a period of 1 year after institutional ethical committee clearance. SAMPLE SIZE: As per an internal audit conducted from November 15, 2019 to December 15, 2019 Total number of patients referred beyond 30 weeks as preterm labour was 86 Total number of patients referred beyond 30 weeks who had preterm delivery (vaginal or Caesarean ) was 28 This was used for sample size calculation SAMPLE SIZE N = ( Z2 1-a/2 P (1-P))/ (eP )2 P= anticipated population proportion e= relative precision (minimum 10% to maximum 20% ) From the pilot study: expected proportion = 0.28 relative precision(%) = 20 desired confidence level ( 1-a ) = 95 required sample size = 233 Anticipating 10% dropout rates final sample size =260 RESULTS: Of the total study subjects, 63.1% had preterm deliveries. 40.4 % of the patients delivered immediately. The preterm perinatal mortality rate was 5.8%. CONCLUSION: The independent risk factors identified, which may result in preterm birth from this study are a previous history of preterm birth, if the mother is diabetic, if mother is anemic and exposure to tobacco. The independent risk factors identified for immediate birth were history of previous preterm birth, mother being a multigravidae, hypertension in the mother and bronchial asthma in mother. The use of progesterone supplements weas found to be protective against both preterm birth and immediate birth. The independent factors supporting favourable neonatal outcome was a maternal age of 25 years or less, progesterone supplementation and administration of antenatal corticosteroids. The factors hindering a favourable neonatal outcome included hypertension and stress. The independent risk factors identified, which may result in perinatal mortality are mother being hypertensive, exposure to tobacco and periodontal infections in the mother. Maternal age of 25 years or less was found to be a protective factor.
