Spontaneous abortions (miscarriages): analysis of cases at a tertiary center in North Central Nigeria

ABSTRACT

Background: Spontaneous abortion (miscarriage) is a source of pregnancy loss globally. Its management; especially in low resource countries remains hampered by inadequate facilities for evaluation. Objectives: To assess the clinical presentation; diagnosis; and treatment of cases of spontaneous abortion at a tertiary hospital in Ilorin; Nigeria. Methodology: A descriptive study of all spontaneous abortions (miscarriages) managed at the University of Ilorin Teaching Hospital; Ilorin; Nigeria between January 1; 2007 and December 31; 2011. The records were retrieved from the medical records department and necessary information retrieved. Results: There were 603 miscarriages with a prevalence of 4.2; incomplete miscarriage was the most common 254 (42.1); 356 (59.0) had no identifiable risk factor; 434 (72) of the women were 35 years; 361 (59.9) had first trimester miscarriages; 272 (45.1) were of low parity (Para 0-1) and 223 (37) were having a repeat miscarriage. Of the 141 managed for threatened miscarriage; pregnancy was salvaged in 90 (63.8); 244 (40.5) had surgical evacuation with 100 success rate while 218 (36.2) had medical management with 90.8 success rate. The mean duration of admission was shortest with surgical management (2.03 ? 1.1 days) and post-abortion infection rate was 11 (2.6 success rate. The mean duration of admission was shortest with surgical management (2.03 ? 1.1 days) and post-abortion infection rate was 11 (2.6). Histology confirmed product of conception in 98 and molar gestation in 2 of the samples; no mortality was recorded in this study. Conclusion: More than half of women with miscarriages had no identifiable risk factors mainly due to limitation in facilities for evaluation; there is a need to improve facilities for investigating women with spontaneous abortions in developing countries to identify the causes of the losses
