Abstract

Primary postpartum hemorrhage (PPH) is an important cause of maternal mortality. There are
many risk factors for PPH. This case-control study aimed to identify risk factors of PPH in Naresuan
University hospital. The data were collected from pregnant women who gave labor between April 2014
to July 2017. Study population consisted of 118 cases of postpartum hemorrhage patients and 236 controls
(no postpartum hemorrhage patients). The causes of PPH were uterine atony (45.8%), vaginal laceration
(27.1%), placenta problems (14.4%) and other causes or multiple causes (12.7%). Significance risk factors
of PPH found in this study were grand multiparity (≥ G4) (OR 2.753; 95%CI 1.209-6.272, p-value 0.013),
multiple gestation (OR 6.268; 95%CI 1.245-31.548, p-value 0.019), operative obstetrics (OR 3.142;
95%CI1.447-6.823, p-value 0.003), retained pieces of placenta (OR 12.142; 95%CI 2.645-55.737), placenta
previa (p-value < 0.001) and prolonged second stage of labor (OR 2.734; 95%CI 2.250-3.324, p-value
0.003). Based on our findings, pregnant women, who has these risk factors, should be used to monitor and
early manage for postpartum hemorrhage
