Abstract
OBJECTIVE: The objective of this study is to explore whether increase in use of second-line conservative surgical procedures will alter the rate of peripartum hysterectomies in management of severe postpartum haemorrhage (PPH). METHODS: This is a retrospective cohort. All pregnant patients with gestation > = 28 weeks with severe PPH (> = 1.5 L) within 72 h of delivery from year 2000 to 2015 (16-year period) in an obstetric training unit was recruited. Basic patient anthropometric characteristics and the main causes for PPH were calculated. The incidence of any second-line conservative surgical procedures and peripartum hysterectomies were evaluated. The total number of patients in each category was then stratified into four 4 years-intervals (4 quadrennium) to compare trends. RESULTS: The incidence of severe PPH gradually increased over the study period (lowest 0.21% in 2002 to 0.76% in 2015) (p < .001). There is an obvious increasing trend in the overall use of second-line surgical procedures from nil to 82% (p < .001), with balloon tamponade constituting up to 48%. The incidence of successful second-line procedures increased gradually from 72.2% in the second quadrennium to 89% in the fourth quadrennium. The total peripartum hysterectomy rate among cases of severe PPH could be seen to drop from 40.2% in the first to 10.9% in the fourth quadrennium (p = .04). CONCLUSIONS: Despite the increasing trends in PPH, the increasing utilisation of second-line conservative surgical procedures in severe PPH should be able to reduce the need for peripartum hysterectomy.
