Abstract:
Objective To evaluate the accuracy of respirophasic variation in carotid artery blood flow peak velocity(ΔVpeak-CA)in predicting fluid responsiveness in the patients undergoing surgery in the prone position. Methods Forty-three American Society of Anesthesiologists physical status Ⅰ-Ⅲ pa-tients of both sexes, aged 45-75 yr, with body mass index of 20-25 kg∕m2, scheduled for elective posteri-or approach lumbar surgery, were enrolled in the study.After induction of anesthesia, hydroxyethyl starch 130∕0.4 sodium chloride injection 7 ml∕kg was intravenously infused over 20 min when the patients were in the prone position.Subjects were classified as responders if stroke volume index increased≥15% after vol-ume expansion.The receiver operating characteristic curve for ΔVpeak-CA in determining positive fluid re-sponsiveness was drawn. Results The results of receiver operating characteristic curve analysis showed that: the cut-off value of ΔVpeak-CA in predicting positive fluid responsiveness was 7.94%, sensitivity 81.8%, specificity 70.0%, and the area under the curve(95% confidence interval)was 0.818 (0.378-0.757). Conclusion Respirophasic ΔVpeak-CA can accurately predict fluid responsiveness in the patients undergoing surgery in the prone position.
