超声检测下腔静脉呼吸塌陷指数预测全麻患者容量反应性的研究

Study on Prediction of Capacity Reactivity in Patients with General Anesthesia by Sonography

目的研究超声检测下腔静脉呼吸塌陷指数预测全麻患者容量反应。方法将40例实施全麻的患者随机分成两组:实验组患者补液后每搏输出量SVI升高大于10%;对照组SVI升高小于10%,比较两组患者的下腔静脉塌陷指数CI。结果对照组患者下腔静脉呼吸塌陷指数小于40%,实验组患者塌陷指数大于40%,绘制的ROC曲线双尾才有意义。结论对于全麻患者在下腔静脉呼吸塌陷指数大于40%可积极进行补液,如果患者下腔静脉呼吸塌陷指数小于40%则要对患者补液进行慎重考虑。

Objective To evaluate the capacity response of hypothalamic respiratory collapse index in patients with general anesthesia.Methods Forty patients with general anesthesia were randomly divided into two groups.In the study group,the stroke volume SVI increased by more than 10%of the reaction group.In the control group,stroke volume SVI increased by less than 10%.Then,the inferior vena cava collapse index Cl of the two groups of patients was compared.Results The patients in the control group had less than 40%of the inferior vena cava respiratory collapse index and the study group had a collapse index of more than 40%.Thus,the ROC curve was meaningful.Conclusion For patients with general anesthesia in the inferior vena cava respiratory collapse index is greater than 40%,rehydration could be actively applied;for patients in the inferior vena cava respiratory collapse index is less than 4 0%,rehydration should be carefully considered.
