Abstract
OBJECTIVE: To examine the impact of using intraoperative cell salvage (ICS) for the restoration of coagulation function in cases of massive Post-Cesarean Section Hemorrhage (PCSH). METHODS: A retrospective analysis was conducted on 60 cases of massive PCSH meeting inclusion criteria at Suqian Maternity and Children's Hospital from January 2020 to July 2022. Patients were divided into two groups: allogeneic blood transfusion group (Group A, n = 30) and ICS group (Group B, n = 30), based on transfusion methods. Blood parameters, coagulation function, and adverse reactions were assessed before (T0) and after (T1) transfusion. Patients were categorized into good prognosis (GP) and poor prognosis (PP) groups based on adverse reaction occurrence. Clinical profiles were compared between groups, and multivariate binary logistic regression analysis was employed to evaluate the factors that may affect the prognosis in women with PCSH. RESULTS: No significant differences in routine blood parameters were observed between groups at T0 and T1 (P>0.05). At T0, no significant differences in PT, APTT, TT, or FIB were found between groups (P>0.05). Both groups showed a reduction in PT, APTT, and TT values at T1 compared to T0, with Group B experiencing a more significant decrease than Group A (P<0.05). FIB increased in both groups at T1 compared to T0, with Group B demonstrating a higher increase than Group A (P<0.05). Both groups showed increased blood pressure at T1 compared to T0, with Group B showing a more pronounced elevation than Group A (P<0.05). The occurrence of adverse reactions was significantly lower in Group B (1/30, 3.33%) compared to Group A (7/30, 23.33%) (P<0.05). Logistic regression analysis identified FIB<1.52 g/L and HR<45.35 times/min as factors associated with increased risk of unfavorable outcome in women with PCSH. CONCLUSION: In patients experiencing significant PCSH, ICS may lead to better postoperative recovery of blood parameters, faster restoration of coagulation function, and reduced risk of adverse events compared to ABT. Moreover, early detection of coagulation function and blood gas indexes is crucial for clinicians to implement timely prevention and treatment measures.
