To analyze the clinical application effect of abdominal aortic balloon placement in cesarean section of sinister placenta previa.

A retrospective analysis was performed on the medical records of 50 patients with sinister placenta previa who underwent cesarean section in our hospital from June 2015 to June 2018. The patients were divided into routine group (n=30) and balloon group (n=20) according to the surgical method. Then, the intraoperative and postoperative conditions, general condition of the fetus after delivery, patients' hospitalization period and occurrence of postoperative adverse reactions of the two groups were compared.

The operation time of patients in the balloon group[ (96.49±6.94) min vs (101.49±10.09) min], intraoperative blood loss[ (932.93±81.97) ml vs. (2 010.49±288.39) ml], intraoperative blood transfusion[ (652.47 ±88.94) ml vs. (1 546.39±237.18) ml] and hysterectomy rate (5% vs. 30%) were significantly lower than the conventional group, and the difference was statistically significant (t=3.055, 27.633, 26.985, χ²=4.678, P<0.05) . There was no significant difference in the rate of intraoperative bladder injury between the two groups (0% vs. 3.33%, χ²=0.680, P>0.05) . Total hospital stay in the balloon group [ (4.69±0.34) d vs. (5.27±1.06) d], DIC incidence (0% vs. 20%) , incidence of hemorrhagic shock (0% vs. 23.3%) and renal dysfunction rate (5% vs. 33.3%) were significantly lower than those of the conventional group (t=2.064; χ²=5.613, 4.454, 5.425; P<0.05) . There was no significant difference in postoperative infection rate (10% vs. 20%) between the two groups (χ²=0.399, P>0.05) . The fetal weight of the two groups after delivery [ (2.65±0.62) kg vs. (2.57±0.37) kg] and 1 min Apgar score [ (8.49±1.65) points vs. (8.86±2.07) points], 5 min Apgar score[ (9.53±0.97) points vs. (9.72±1.06) points] had no significant difference between the two time points (t=0.517, -0.701, -0.653; P>0.05) ; There was no significant difference in the incidence of postoperative adverse reactions (3.3% vs. 15%) between the two groups (χ²=0.779, P>0.05) .

Abdominal aortic balloon occlusion before cesarean section in sinister placenta previa can improve the intraoperative and postoperative conditions, and reduce the possibility of placental resection, and the safety is relatively good.
