超声引导监测下腹主动脉下段球囊阻断术在凶险性前置胎盘剖宫产术中的应用效果研究

Application Effect of Lower Abdominal Aorta Balloon Occlusion under Ultrasound Guidance and Monitoring during Cesarean Section in Patients with Pernicious Placenta Previa

目的:探讨超声引导监测下腹主动脉下段球囊阻断术在凶险性前置胎盘剖宫产术中的应用效果。方法:选取2014年1月至2021年4月我院医治的凶险性前置胎盘剖宫产术患者120例,依据随机数字表法分为对照组和试验组,每组各60例。对照组患者行常规剖宫产,试验组患者剖宫产术中在超声引导监测下行腹主动脉下段球囊阻断术,两组患者术后均给予常规抗感染治疗。比较两组患者围术期情况、术中生命体征情况和术后情况。结果:试验组患者手术时间短于对照组,且术中出血量、输血量和子宫切除率均低于对照组(P<0.05);试验组患者术中收缩压、心率和血氧饱和度波动幅度均小于对照组(P<0.05);试验组患者术后肾功能异常率和转ICU率均低于对照组,且住院时间短于对照组(P<0.05)。结论:超声引导监测下腹主动脉下段球囊阻断术能稳定凶险性前置胎盘剖宫产手术患者生命体征,改善患者围术期和术后情况,安全性更高。

Objective:To explore the application effect of lower abdominal aorta balloon occlusion under ultrasound guidance and monitoring in cesarean section for pernicious placenta previa.Methods:120 cases of cesarean section patients with pernicious placenta previa in our hospital from January 2014 to April 2021 were selected and divided into the study group and the control group according to random number table method,60 cases in each group.The control group underwent routine cesarean section,and the study group performed balloon occlusion of lower abdominal aorta under ultrasound guidance and monitoring during cesarean section.Both groups were given routine anti-infection therapy after operation.The perioperative situation,intraoperative vital signs and postoperative conditions of the two groups of patients were compared.Results:The operation time of the study group was shorter than that of the control group,and the amount of blood loss,blood transfusion during operation and hysterectomy rate of the study group were lower than those of the control group(P<0.05).Intraoperative systolic pressure fluctuations,heart rate fluctuations and blood oxygen saturation fluctuations of patients in the study group were lower than those in the control group(P<0.05).The incidence of abnormal renal function and rate of ICU transfer of the study group were lower than those in the control group,and the hospital stay was shorter than that of the control group(P<0.05).Conclusion:Lower abdominal aorta balloon occlusion under ultrasound guidance and monitoring can stabilize the vital signs of patients with pernicious placenta previa during cesarean section,improve the perioperative and postoperative conditions of the patient,and have higher safety.
