［Abstract］ Objective：To explore the experience of anesthesia management in perioperative period of cesarean section in patients with pregnancy complicated with placenta implantation.Methods：By querying the HIS system of our hospital from October 2017 to April 2022，the patient 's case data diagnosed as ' cesarean section and placenta implantation ' were discharged.According to the degree of implantation, they were divided into three groups : 19 cases of adhesive type（group A）, 43 cases of implanted type（group B)and 30 cases of penetrating type(group C).Record and analyze the patient 's general condition.Timesr of pregnancies and deliveries、anesthesia、Intraoperative blood loss, duration of surgery, length of hospital stay, ICU occupancy rate, blood transfusion, preoperative abdominal aortic balloon, ureteral stent placement or not, maternal hysterectomy, neonatal general condition, Aprgar score, etc.Results Compared with group A, the gestational age of group C was significantly lower than that of group A, and the difference was statistically significant (P＜0.05). The proportion of spinal anesthesia in group C ( 73.33 % ) was significantly lower than that in group A and B, and the proportion of general anesthesia ( 6.67% ) was higher than that in the two groups ( P 0.01 ).The intraoperative blood loss, intraoperative input of red blood cells, plasma and autologous blood in group C were significantly higher than those in group A and group B (P 0.01 ). The hospitalization time and operation time in group C were significantly longer than those in group A and group B ( P 0.01 ). The neonatal weight in group C was significantly lower than that in group A (P 0.01 ).Compared with group A, the proportion of preoperative abdominal aortic balloon placement ( 80% ) and ureteral stent placement ( 56.67 % ) in group C were significantly higher than those in group A and group B ( both P 0.01 ).Conclusions：With the aggravation of placental implantation, the proportion of intraspinal anesthesia decreased, and the proportion of general anesthesia increased, but good combined spinal epidural anesthesia still dominated. In this study, placental implantation is still dominated by intraspinal anesthesia.Obstetrical autologous blood transfusion reduces the amount of allogeneic blood input. This study confirms that it is safe and effective.The intraoperative blood loss was reduced and the hysterectomy rate was significantly decreased in patients with preoperative abdominal aortic balloon placement.Perfect preoperative preparation, active multidisciplinary consultation, strict intraoperative monitoring, and reasonable perioperative anesthesia management are important supports for ensuring patient safety.
