Trends in maternal mortality at University of Maiduguri teaching hospital, Maiduguri, Nigeria - A five year review

摘要

Background: Maternal mortality is on the rise in Nigeria with the North- East having the highest ratio, and Borno state records one of the highest maternal mortality ratios in the country. Objective: To determine the trends in maternal mortality in UMTH, identify the background socio- cultural factors, establish the major causes of deaths and determine avoidable factors. Study design: Retrospective study of maternal deaths. Methods: The case records of all recorded cases of maternal deaths between January 2001 and December 2005 inclusive were retrieved and relevant data obtained and analysed. Results: The maternal mortality ratio (MMR) for the period under review was 430 per 100,000 live births. There were annual fluctuations in MMR. However, there was a consistently rising trend in MMR from 2002-2004 with the highest ratio of 545 per 100,000 live births recorded in the year 2004, with a decline in 2005. Thirty (78.9%) of these deaths occurred among the unbooked patients and more than 90% of this were referred as obstetric emergencies. Age range was 14-39 years with a mean of 26.5years. The highest maternal death occurred at the two extremes of reproductive age group (14-19 years and 35 years and above). Grandmultiparas suffered the highest maternal mortality of 36.8%, followed by teenage mothers. P1-4 contributed the least to maternal mortality. The direct causes of maternal death accounted for 92.1% of the deaths. The major causes of death were eclampsia 34.2%, sepsis 26.3% and prolonged obstructed labour/ruptured uterus 13.2%. Amongst the indirect causes of maternal death, HIV/Tuberculosis was the leading cause accounting for 5.3%. Basic but professional antenatal care, skilled attendance at birth, community mobilization and health education messages for a healthy pregnancy and safe birth will help to reduce the unacceptably high maternal mortality ratio in Borno state and the country at large.
