Compressive sutures are associated with less hemoglobin depletion in postpartum hemorrhage due to uterine

Objectives: To determine the association between the use of compressive sutures and the decrease in hemoglobin at 24 hours in post cesarean section patients diagnosed with postpartum hemorrhage (PPH) due to uterine atony. Materials and methods: Retrospective cohort analytical study in 625 postoperative patients diagnosed with postpartum hemorrhage due to uterine atony in a national maternal perinatal institute between July and December 2020. The association was evaluated by t student and multiple linear regression determining the crude and adjusted association using confounding variables. Results: A total of 157 medical records were included in the analysis. The mean age was 29.1 +/- 6.6 years, median body mass index 30.5 kg/m2 and median prenatal care was 2. No adverse events were reported for the use of compressive sutures. The use of compressive sutures was associated with a lower 24-h hemoglobin decrease of 0.37 mg/dL (95% CI -0.73; -<0.01, p=0.045) on average, controlled for confounding variables. Conclusions: Compressive suturing is an effective first-line surgical procedure in the surgical management of PPH. No adverse events were found in the study population. The use of compressive sutures had on average a lower decrease in hemoglobin at 24 hours compared to the nonuse of compressive sutures.
