Abstract
Obstetric hemorrhage remains one of the major causes of maternal death in both developed and developing countries. Because of its importance as a leading cause of maternal mortality and morbidity, and because of evidence of substandard care in the majority of fatal cases, obstetric hemorrhage must be considered as a priority topic for national guideline development. Obstetric hemorrhage encompasses both ante-partum and postpartum bleeding (Penney & Brace, 2007).
Primary post-partum hemorrhage (PPH) is defined as blood loss greater than or equal to 500 ml within 24 hours after birth, while severe PPH is blood loss greater than or equal to 1000 ml within 24 hours (WHO guidelines for the management of postpartum hemorrhage and retained placenta, 2009). PPH can be classified to minor (500-1000 ml) or major (more than 1000 ml). Major could be divided to moderate (1000-2000 ml) or severe (more than 2000 ml) (Mousa, 2007). Aim of the work.The aim of this study is to: Assess the efficiency of prophylactic bilateral uterine artery ligation in reducing incidence of postpartum hemorrhage in cesarean section in patients at risk of uterine atony. Patients and Methods: Type of the Study: A prospective randomized controlled clinical trial. Study Settings: This clinical trial will be conducted at Ain-Shams University Maternity Hospital. In the period from December 2014 till December 2016. Study Population: The patients will be recruited from women attending labor ward to undergo cesarean section.
