全身麻醉患者无创血压与有创血压的对比研究

摘要

Objective To investigate the differences of invasive blood pressure( IBP) and non-invasive blood pressure( NIBP) in general anesthesia.Methods Eighty-two patients undergoing general anesthesia were divided into four groups depending on invasive systolic blood pressure (ISBP):group A, ISBP≤90mmHg;group B,ISBP 90-120 mmHg;group C, ISBP 120-150mmHg;group D, ISBP>150mmHg.Non-invasive blood pressure and arterial blood pressure was monitored at the same time.Bilateral NIBP and IBP val-ues were compared by paired t-test and linear correlation analysis.Results There was no significant difference between bilateral NIBP of four groups.Invasive systolic blood pressure was lower than bilateral non-invasive systolic blood pressure in group A (P<0.05).In-vasive systolic blood pressure was higher than bilateral non-invasive systolic blood pressure in group B,C and D ( P<0.05) and the difference was more significant when the blood pressure was more higher.There was no significant difference between arterial diastolic blood pressure and bilateral non-invasive diastolic blood pressure in group A and D(P>0.05).Arterial diastolic blood pressure was sig-nificantly lower than bilateral non-invasive diastolic blood pressure in group B and C.There was significant correlation between arterial systolic blood pressure and bilateral non-invasive systolic blood pressure (r=0.940,P<0.01).There was significant correlation be-tween arterial diastolic blood pressure and bilateral non-invasive diastolic blood pressure (r=0.925,P<0.01).Conclusion There was significant difference and correlation between arterial blood pressure and non-invasive blood pressure.Arterial blood pressure can be estimated by non-invasive blood pressure in certain blood pressure range.%目的：探讨全身麻醉患者双侧肱动脉无创血压（ NIBP）与桡动脉有创动脉压（ IBP）的关系。方法于全身麻醉下进行手术的患者82例，麻醉诱导前后及术中同步测量双侧无创血压及有创血压，根据有创收缩压值（ ISBP）大小分为A组（ ISBP≤90mmHg）、B组（90mmHg＜ISBP≤120mmHg）、C组（120mmHg＜ISBP≤150mmHg）和D组（ISBP＞150mmHg）。对各组数值进行差异分析，并对有创血压和无创血压值做线性相关分析。结果4组患者双侧无创血压无统计学差异（P＞0．05）；A组有创收缩压低于双侧无创收缩压（P＜0．05）；B、C、D组有创收缩压高于双侧无创收缩压（P＜0．05），且随着血压升高差值呈逐渐增高趋势；A、D组有创舒张压与双侧无创舒张压差异无统计学意义（P＞0．05）；B、C组有创舒张压低于双侧无创收缩压（P＜0．05）。有创收缩压与同侧袖带收缩压显著相关（r＝0．940，P＜0．01），有创舒张压与同侧袖带舒张压显著相关（r＝0．925，P＜0．01）。结论全麻平卧位患者有创血压与无创血压显著相关，在一定血压范围内，可通过无创血压对有创血压进行初步估计。
