脉搏灌注变异指数监测肠道手术患者容量反应性的临床研究
Clinical study on pleth variability index for monitoring volume responsiveness in patients undergoing intestinal tract surgery
摘要
Abstract
Objective To evaluate the ability of pleth variability index(PVI) for predicting volume responsiveness after general anesthesia induction intubation in the patients undergoing intestinal tract surgery with the velocity-time integral(VTI) of left ventricular outflow tract blood monitored by transthoracic echocardiography as the standard.Methods Twenty-five patients undergoing intestinal tract surgery were selected.After general anesthesia induction,7 mL/kg colloidal solution was infused before operation beginning,if the VTI increased percentage(△VTI％)≥10 ％,200 mL colloidal solution was infused by 50mL syringe until △VTI％＜10％;the hemodynamic indicators of MAP,CVP,HR,PI VTI and PVI were recorded before and after infusion solution.Results The PVI basic value in the patients with response was significantly higher than that in the patients without response(P＜0.05);the Pearson correlation analysis found that there was a significant linear correlation between PVI basic value and △VTI％ before infusion solution(P＜0.05);the optimal diagnostic threshold value of PVI was 13.51,its sensitivity for monitoring the volume responsiveness was 69.25％ and specificity was 70.00％.The area under the receiver operating characteristic(ROC) curve(AUC) was 0.75(95％ CI:0.63-0.88,P＜0.01).Conclusion PVI can predict the volume responsiveness in the patients undergoing intestinal tract surgery.The PVI value ＞13.51 indicates that the patient may be in hypovolemia status and needs the volume therapy.关键词
