超声监测下腔静脉参数在宫腔镜手术麻醉中的应用研究

Study on the Application of Ultrasound Monitoring of Inferior Vena Cava Parameters in Hysteroscopic Surgery Anesthesia

目的探讨超声监测下腔静脉参数在宫腔镜手术中的应用价值。方法100例全身麻醉宫腔镜手术患者随机分为两组。对照组通过检测前负荷指标,观察组通过超声监测下腔静脉参数,以评估围术期容量状态。比较两组的液体补入情况、容量参数。结果观察组的液体补入量少于对照组,液体补入时间短于对照组,低血压、寒战发生率均低于对照组(P<0.05)。补液后,观察组的IVCe、IVCi均高于对照组,dIVC低于对照组(P<0.05)。结论超声监测下腔静脉参数可准确反映宫腔镜手术患者麻醉中容量状态,指导术中补液,减少低血压的发生。

Objective To explore the application value of ultrasound monitoring of inferior vena cava parameters in hysteroscopic surgery.Methods 100 patients with hysteroscopic surgery under general anesthesia were randomly divided into two groups.The control group received detection of pre-load indicators,and the observation group received ultrasound monitoring of inferior vena cava parameters to evaluate the perioperative volume status.The liquid replenishment and the volume parameters were compared between the two groups.Results The amount of liquid supplementation in the observation group was less than that in the control group,the time of liquid supplementation was shorter than that in the control group,and the incidences of hypotension and chills were lower than those in the control group(P<0.05).After rehydration,IVCe and IVCi in the observation group were higher than those in the control group,and dIVC was lower than that in the control group(P<0.05).Conclusions Ultrasound monitoring of inferior vena cava parameters can accurately reflect the volume status of patients with hysteroscopic surgery during anesthesia,guide intraoperative fluid infusion,and reduce the occurrence of hypotension.
