【摘要】：目的探討被動(dòng)抬腿(PLR)后每搏輸出量變化率(ΔSV)對(duì)全身麻醉(全麻)誘導(dǎo)后低血壓發(fā)生的預(yù)測(cè)價(jià)值。方法 44例全麻下行胃腸道手術(shù)的患者根據(jù)有無(wú)高血壓病史分為高血壓組(H組,24例)和血壓正常組(N組,20例),分別監(jiān)測(cè)兩組患者麻醉誘導(dǎo)前后HR、SBP、DBP和MAP的變化,計(jì)算PLR后ΔSV和麻醉誘導(dǎo)后低血壓[SBP變化率(ΔSBP)≥20%]的發(fā)生率。結(jié)果 H組麻醉誘導(dǎo)后低血壓發(fā)生率高于N組(79.1%vs.40.0%)(P0.05)。H組PLR后ΔSV與ΔSBP呈正相關(guān)(r=0.43,P0.05),N組PLR后ΔSV與ΔSBP無(wú)明顯相關(guān)性(r=0.34,P0.05)。H組和N組PLR后ΔSV的AUC分別為0.80和0.77。PLR后ΔSV預(yù)測(cè)H組和N組患者發(fā)生誘導(dǎo)后低血壓的靈敏度分別為68.4%和87.5%,特異度分別為100%和75.0%,診斷界值分別為9.6%和7.7%。結(jié)論 PLR后ΔSV能預(yù)測(cè)全麻誘導(dǎo)后低血壓的發(fā)生;與血壓正常患者相比,ΔSV預(yù)測(cè)高血壓患者發(fā)生全麻誘導(dǎo)后低血壓的準(zhǔn)確性與特異度高,而靈敏度低。
[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，
