Carotid FTc and ΔVpeak-CA Assessing Fluid Responsiveness before An-esthesia Induction in Patients with Gastrointestinal Cancer
摘要
Abstract
Objective:To evaluate the accuracy of carotid corrected flow time(FTc)and respirophasic variation in carotid artery blood flow peak velocity(∆Vpeak-CA)in predicting gastrointestinal cancer patients'fluid responsiveness before anesthesia induc-tion.Methods:61 patients,24 males and 37 females,aged 18～65,with BMI of 18～30 kg/m2 and ASA physical status Ⅰ to Ⅱ,scheduled for elective gastrointestinal cancer surgery with general anesthesia from July 2019 to November 2021,were enrolled in the study.Volume load test(intravenous infusion of com-pound sodium chloride solution 10 mL/kg,which was completed at a uniform speed within 25～30 min)was performed in all pa-tients before anesthesia induction.Fluid responsiveness was defined as the 10％or more increase in stroke volume(∆SV)after the fluid challenge,which serves as a benchmark for assigning 21 patients to the non-responder group and 40 patients to the responder group.Heart rate,mean arterial pressure,carotid systolic flow time,cycle time,ejection fraction,stroke volume,maximum ca-rotid artery blood flow peak velocity and minimum carotid artery blood flow peak velocity were recorded 5 min before and 5 min after volume load test.The receiver operating characteristic(ROC)curve of carotid FTc and ∆Vpeak-CA predicting fluid responsiveness before anesthesia induction in patients with gastrointestinal cancer was plotted.Results:Carotid FTc was negatively correlated to∆SV(r =-0.67,P<0.001).The area under the curve of carotid FTc predicting fluid responsiveness was 0.774,with the sensi-tivity and specificity of 80％and 71.4％.∆Vpeak-CA was positive correlated to ∆SV(r = 0.425,P<0.001).The area under the curve of ∆Vpeak-CA predicting fluid responsiveness was 0.768,with the sensitivity and specificity of 77.5％and 61.9％.Con-clusion:Both carotid FTc and ∆Vpeak-CA are valuable in predicting fluid responsiveness before anesthesia induction in patients undergoing gastrointestinal surgery.关键词
