摘　　要：目的 探讨触摸法、最低漏气法和被动回流法用于气管导管套囊压评估的准确性和安全性。方法 本次研究为前瞻性随机对照研究,选择行择期全麻气管插管手术的患者150例,按照随机数字表法分为三组:MP组、MOV组和PR组,各为50例。MP组采用触摸法,MOV组采用最低漏气法,PR组采用注射器被动回流法,比较三组套囊压力实测值以及套囊压力分级情况。结果 MP组、MOV组和PR组患者的套囊压力实测值分别为(58.95±17.55)cmH_(2)O、(25.67±8.49)cmH_(2)O和(29.68±7.35)cmH_(2)O,三组之间比较,差异有统计学意义(F=114.00,P<0.05),MP组患者的套囊压力实测值明显高于MOV组和PR组,差异均有统计学意义(q分别=19.56、17.20,P均<0.05),MOV组和PR组患者之间套囊压力实测值比较,差异无统计学意义(q=2.35,P>0.05)。MP组、MOV组和PR组压力准确率(处于常压分级)分别为6.00%、64.00%和44.00%。MOV组压力准确率高于MP组和PR组,差异均有统计学意义(χ^(2)分别=61.60、8.65,P均<0.05)。结论 最低漏气法用于气管插管患者套囊压力的评估具备较高的准确性和安全性。Objective To investigate the accuracy and safety of manual palpation,minimum occlusive volume and pas-sive reflux in the evaluation of endotracheal tube cuff pressure.Methods This study was a prospective randomized con-trolled trial that included 150 patients undergoing elective general anesthesia for tracheal intubation.The patients were di-vided into three groups using a random number table:MP group,MOV group and PR group(n=50).The MP group was treated with the manual palpation,the MOV group was treated with the minimum air leakage,and the PR group was treat-ed with passive reflux using syringe.The cuff pressure values and cuff pressure grading were compared among the three groups.Results The measured values of cuff pressure in MP,MOV and PR groups were 58.95±17.55 cmH_(2)O,25.67±8.49 cmH_(2)O and 29.68±7.35 cmH_(2)O,respectively.The difference among the three groups was statistically significant(F=114.00,P<0.05),the pressure in MP group was significantly higher than that in MOV and PR groups(q=19.56,17.20,P<0.05).There was no statistically significant difference between MOV and PR groups(q=2.35,P>0.05).Pressure accura-cy of MP,MOV,and PR groups were 6.00%,64.00%and 44.00%.The accuracy rate of cuff pressure in the MOV group was higher than that in the MP and PR groups(χ^(2)=61.60,8.65,P<0.05).Conclusion The minimal air leakage tech-nique for assessing cuff pressure in tracheal intubation patients demonstrates higher accuracy and safety.
