Rezumat: Introduction. Postpartum hemorrhage (PPH) is a significant
maternal health concern, representing a major cause
of obstetric mortality globally. Materials and method. In
this retrospective study, we analyzed cases of postpartum
hemorrhage, from April 2019 to April 2021, from the “Bucur”
Maternity, Bucharest. Results. This study included 100 cases
of postpartum hemorrhage. Among them, 30 occurred
after caesarean sections and 70 occurred following
vaginal deliveries. The identified causes of PPH after caesarean
section were uterine atony (90%), placental retention
(6.66%) and uterine rupture (3.33%). For PPH after vaginal
delivery, uterine atony was identified as the most common
cause in 38 patients. Multiparity was the most frequent
cause of uterine atony. Conclusions. The most common
cause of postpartum hemorrhage was uterine atony,
being more frequent after caesarean section. SARS-CoV-2
infection correlated with an increased frequency of uterine
atony and postpartum hemorrhage. Cuvinte cheie: postpartum hemorrhage, uterine atony, caesarean section.
