【摘要】：目的探讨被动抬腿(PLR)后每搏输出量变化率(ΔSV)对全身麻醉(全麻)诱导后低血压发生的预测价值。方法 44例全麻下行胃肠道手术的患者根据有无高血压病史分为高血压组(H组,24例)和血压正常组(N组,20例),分别监测两组患者麻醉诱导前后HR、SBP、DBP和MAP的变化,计算PLR后ΔSV和麻醉诱导后低血压[SBP变化率(ΔSBP)≥20%]的发生率。结果 H组麻醉诱导后低血压发生率高于N组(79.1%vs.40.0%)(P0.05)。H组PLR后ΔSV与ΔSBP呈正相关(r=0.43,P0.05),N组PLR后ΔSV与ΔSBP无明显相关性(r=0.34,P0.05)。H组和N组PLR后ΔSV的AUC分别为0.80和0.77。PLR后ΔSV预测H组和N组患者发生诱导后低血压的灵敏度分别为68.4%和87.5%,特异度分别为100%和75.0%,诊断界值分别为9.6%和7.7%。结论 PLR后ΔSV能预测全麻诱导后低血压的发生;与血压正常患者相比,ΔSV预测高血压患者发生全麻诱导后低血压的准确性与特异度高,而灵敏度低。
[Abstract]:Objective to investigate the effects of general anesthesia (general anesthesia) on the change rate of stroke output (螖 SVV) after passive leg lifting (PLR). Methods 44 patients undergoing gastrointestinal surgery under general anesthesia were divided into two groups according to their history of hypertension. (24 cases) and 20 cases of normal blood pressure group (n = 20) were used to monitor the changes of PLR and MAP before and after anesthesia induction, and to calculate 螖 SV after PLR and hypotension after anesthesia induction. [Results the incidence of hypotension in group H was higher than that in group N after anesthesia induction (螖 SBP 鈮，
