Decision to delivery interval, maternal and fetal outcomes in emergency caesarean sections in a tertiary teaching hospital, Dar es salaam, Tanzania

Background: Emergency caesarean section (CS) answers the question on how soon the procedure should be performed. Maternal and fetal outcomes deteriorate when decision to delivery interval (DDI) exceeds 75 min. This study aimed at determining the DDI, Maternal and fetal outcomes in CS categories at Muhimbili National Hospital (MNH). Methodology: A descriptive cross-sectional study involving 427 emergency CS at MNH was conducted from September to November, 2017. Data was extracted and analysed using SPSS version 23.0 where frequency, means, chi-square test and DDI were calculated to determine its association with categories of CS. Results: The mean DDI for category one, two and three CS were 126.73, 133.57 and 160.08 min respectively. Only two (0.5%) and 54 (12.6%) of category one and two emergency CS met the recommended DDI of 30 and 75 min respectively. Maternal and fetal adverse outcome were increasing with increase in DDI. There was no significant association between DDI and adverse maternal outcome (OR: 1.2; 95% CI 0.49-2.83) and fetal outcome (OR: 1.7; 95% CI 0.91-3.38). Conclusion: The proportions of adverse maternal and fetal outcome were high when DDI was ≥ 75 min. Improving triage of the patients according to their urgency is crucial in reducing prolonged DDI.
