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 cmH2O,25.67±8.49 cmH2O and 29.68±7.35 cmH2O,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(χ2=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.
