RESUMEN
This is a descriptive cross-sectional study over a nine months period conducted at the UTH-Yalgado Ouédraogo from all patients in whom the diagnosis of endometritis at obstetrical been laid. Endo-cervical and vaginal swabs were taken from all these patients. Commensal bacteria and anaerobes were investigated in the laboratory. During the study period, 102 cases of obstetric endometritis were recorded that to say a frequency of 1.4% of admissions. The average age of patients was 25.2 years [17-43]. The childbirth mean was 2.5 ± 2 [0-7]. The reason for consultation was dominated by hyperthermia in 98% of cases. The bacterial ecosystem was mainly dominated by Escherichia coli (49.2%), Staphylococcus aureus (29.5%), Streptococcus sp (4.9%). The acid + amoxicillin clavulanic showed low activity on most germs. The average hospital stay of patients was 6.30 days [1-33]. A maternal death was recorded in 3 patients that to say fatality rate of 2.9%. The lethality of endometritis at the UTH-Yalgado Ouedraogo is greater than the rate of 1% allowed by WHO. The resistance of germs is high enough with amoxicillin. The systematization of the bacteriological study is expected to guide the antibiotic to help better fight against maternal mortality.
