Background:
Obstetric hemorrhage is the leading cause of maternal mortality globally, especially in China. The key to a successful rescue is immediate and rapid blood transfusion. Autotransfusion has become an integral part of clinical blood transfusion, with intraoperative cell salvage (IOCS) being the most widely used.
Aim:
To investigate the application of IOCS in cesarean section.
Methods:
A total of 87 patients who underwent cesarean section and blood transfusion in our hospital from March 2015 to June 2020 were included in this prospective controlled study. They were divided into the observation (43 cases) and control (44 cases) groups using the random number table method. The patients in both groups underwent lower-segment cesarean section. The patients in the control group were treated with traditional allogeneic blood transfusion, whereas those in the observation group were treated with IOCS. Hemorheology [Red blood cell count, platelet volume, and fibrinogen (FIB)] and coagulation function (partial prothrombin time, prothrombin time (PT), platelet count, and activated coagula-tion time) were measured before and 24 h after transfusion. In the two groups, adverse reactions, such as choking and dyspnea, within 2 h after cesarean section were observed.
Results:
Before and after transfusion, no significant differences in hemorheology and coagulation function indices between the two groups were observed (P > 0.05). About 24 h after transfusion, the erythrocyte count, platelet ratio, and FIB value significantly decreased in the two groups (P < 0.05); the PLT value significantly decreased in the two groups; the activated partial thromboplastin time, PT, and activated clotting time significantly increased in the two groups (P < 0.05); and no statistical differences were observed in hemorheology and coagulation function indices between the two groups (P > 0.05). Furthermore, there was no significant difference in the incidence of adverse reactions between the two groups (P > 0.05).
Conclusion:
In patients undergoing cesarean section, intraoperative cell salvage has a minimum effect on hemorheology and coagulation function and does not increase the risk of amniotic fluid embolism.
