Risk Factors and Outcome of Obstructed Labour at a tertiary care Hospital

Abstract

Background: Obstructed labour is one of the most common preventable cause of maternal and prenatal morbidity and mortality in developing countries. Objective: The purpose of the present study was to determine the risk factors as well as to asses the outcome of obstructed labour.

Method: This cross sectional study was conducted in the Department of Gynecology & Obstetrics at Shaheed Ziaur Rahman Medical College Hospital, Bogra during the period from January 2007 to December 2007. One hundred and five cases with features of obstructed labour were selected as per inclusion and exclusion criteria in a consecutive method. A detailed history included sociodemographic feature, obstetric history, features of obstruction, intrapartum events were recorded to detect risk factors. Condition of patients, mode of delivery, preoperative and post operative complications, maternal and fetal outcomes were recorded.

Results: A total number of 3171 deliveries were conducted during this period and 132 cases of obstructed labour were found constituting an incidence of 4.2%. The highest frequency was found among the unbooked, primigravid patients that were illiterate or only having primary education level. The commonest cause was cephalo-pelvic disproportion (47.5%) followed by fetal malpostion (25.7%) and malpresentation (24.8%). The majority of the patients were between 25-29 years, caeserean section was the most common mode of delivery (78.09%). Maternal morbidity due to different complication accounted for 76.19% of the case while the fetal morbidity was 51.31% of the cases. The maternal mortality was 1% and prenatal mortality was 24.76%.

Conclusion: In this study the incidence of obstructed labour was very high. The commonest cause was cephalo-pelvic disproportion followed by fetal malpostion and malpresentation.
