Background & Objective: Postpartum hemorrhage is the most common cause of maternal morbidity and mortality, which can occur unexpectedly without warning, and without any underlying causes. We hypothesized that administering fibrinogen concentrate to cesarean section patients before surgery would reduce perioperative blood loss.Materials & Methods: In this double-blind randomized controlled parallel group study, a single dosage of fibrinogen concentrate or a placebo was given to 260 cesarean section patients at random (by G*Power software, Heinrich-Heine-Universität Düsseldorf, Germany) in a university-affiliated general hospital between November 11, 2022, to January 8, 2023. Individuals in the fibrinogen group received a dose of one gram of fibrinogen concentrate and those in the placebo group received normal saline solution with the same volume in the placebo group. Total blood loss was the primary outcome of this study.Results: A total of 280 cases were screened and 260 were randomized. With a P-value of 0.001, the median (IQR) volume of bleeding in the fibrinogen group was 660 (341.25) mL, as opposed to 790 (475.00) mL in the placebo group. Comparatively, only 10 (7.7%) of the fibrinogen group and 26 (20%) of the placebo group required blood transfusions (P=0.006). No adverse event related to fibrinogen was reported.Conclusion: Empiric treatment with fibrinogen concentrate results in reduced blood loss.

Background & Objective: Globally, postpartum hemorrhage (PPH) remains a leading cause of maternal deaths. However, in many low and middle-income countries, information on the magnitude of and risk factors for PPH is scarce. Understanding the relative contributions of different risk factors for PPH is important. We assessed the incidence of and risk factors for postpartum hemorrhage among women who had a cesarean section in Iran.Materials & Methods: Between March 2021 and March 2022, a prospective cohort study was conducted at a university-affiliated general hospital for women who had a cesarean section in Iran. We used Spearman’s correlation for the variables associated with PPH.Results: Among the 300 women, the overall incidence of postpartum hemorrhage was 15.7%. Risk factors for postpartum hemorrhage among deliveries by cesarean section were: body-mass index, previous PPH, preoperative anemia, and preoperative hypofibrinogenemia.Conclusion: The incidence of postpartum hemorrhage in the cesarean section was high. Extra vigilance in all women with cesarean section could address the risk factors identified.

Background & Objective: Delayed diagnosis and treatment of postpartum hemorrhage could result in mortality. Today, there is a strong desire to determine the factors affecting postpartum hemorrhage, particularly fibrinogen levels. This study aimed to investigate the role of plasma fibrinogen levels in postpartum hemorrhage and severe postpartum hemorrhage.Materials & Methods: This cross-sectional study was conducted on 169 term pregnant women who were candidates for an elective Cesarean section. Fibrinogen and other coagulating factors were measured before and at the end of the surgery, and twenty-four hours after surgery. Bleeding volume was also measured during and at the end of the surgery, and twenty-four hours after that. The relationship between coagulation factors and the amount of bleeding was examined using statistical tests.Results: Mean plasma fibrinogen levels measured before, at the end of, and 24 hours after surgery were 247.65±91.07 mg/dl, 219.4±75.60 mg/dl, and 223.91±65.44 mg/dl, respectively. Sixty-five patients (38.5%) had postpartum hemorrhage (1000-2000mL) and seven patients (4.1%) had severe postpartum hemorrhage (>2000mL). Of the cases with preoperative fibrinogen levels less than 200mg/dl, 72% had postpartum hemorrhage and 14% had the severe form. There was a strong association between the patient's plasma fibrinogen level with PPH and sPPH (P=0.000).Conclusion: This study showed a strong correlation between plasma fibrinogen levels and postpartum hemorrhage and severe postpartum hemorrhage. In addition, it has been shown that low plasma fibrinogen levels could be a direct prognostic factor for postpartum hemorrhage and severe postpartum hemorrhage. Younger women and preoperative anemia were other strong predictors.
