Factors Influencing Motherswith Atonia Uteri in Elpi Aziz Hospital Rantau Prapat City

 Introduction: Uterine Atony is a condition characterized by the failure of the uterine muscles to contract after the delivery of the placenta, caused by various factors that disrupt the uterus ability to contract and retract. One of the leading causes of maternal mortality in Indonesia is hemorrhage, with the majority of cases occurring during the postpartum period (60% - 70%), mainly due to uterine atony. This research aims to identify the factors that influence mothers with uterine atony. The study was conducted at Elpi-Al Aziz Hospital in Rantau Prapat, North Sumatra. Method: This research employed an analytic study with a Cross-Sectional design, where measurements or observations were conducted simultaneously using quantitative methods through medical records. The research was carried out at Elpi Aziz Hospital, Rantau Prapat, with a population of all maternal medical records from January 2022 to June 2023, totaling 157, and the number of mothers with uterine atony cases was 40. The sampling was done at a 1:3 ratio, resulting in a total of 54 samples, comprising 40 cases and 14 controls. Result and analysis: The research findings revealed that the factors influencing uterine atony cases were as follows: mothers aged <20 to >35 years accounting for 33 individuals (61.1%), grand multiparous mothers accounting for 21 individuals (38.9%), a delivery interval of >4 years which involved 30 individuals (55.6%), a history of abortion in 33 individuals (61.1%), and a history of twin pregnancies in 26 individuals (48.1%).
