Objective: To look for uterine atony (UA) risk factors (RFs). To look for uterine atony (UA) risk factors (RFs).

Methods: This case-control study was carried out between 1st February and 31st May 2019. All women with or without UA were recruited. The main variables recorded included gestational age at delivery, past-history of macrosomic baby (≥4000g), third trimester malaria, intrapartum fever, time spent from four cm cervical dilatation to delivery (TFD), birthweight, UA or not. Data were analysed using SPSS 21.0. Fisher’s exact test, t-test and logistic regression were used for comparison. The level of significance was P<0.05.

Results: UA was present among 49 women (5.5%). Significant RFs for UA included multiple pregnancy (aOR 7.14, 95%CI 2.01-21.43), delivery before 34 weeks (aOR 5.72, 95%CI 1.24-22.04), TFD ?10 hours (aOR 5.57, 95%CI 1.34-26.03), macrosomic baby (aOR 3.64, 95%CI 1.37-9.46), recent malaria or preeclampsia (aOR 3.11, 95%CI 1.11-9.79).

Conclusion: Measures to manage UA should be made ready when these RFs are present.
