The effect of endotracheal catheter cuff inflation method on cuff pressure and tracheal mucosal damage / 重庆医学

ABSTRACT

Objective To investigate the effect of different methods of endotracheal catheter cuff inflation on cuff pressure and tracheal mucosal damage postoperatively .Methods 120 patients undergoing gynecological tumorectomy as a selective operation with general anesthesia were randomly divided into 3 groups with different methods of cuff inflationfinger kneading method ,spe-cialized cuff pressure meter ,and minimum closing volume method .The cuff pressure were measured by specialized cuff pressure gauge and the tracheal mucous membrane was examined by fibrolaryngoscope at the time of withdrawal of endotracheal tube .The cuff pressure and the tracheal mucosal change with different cuff inflation methods were compared .Results The average cuff pres-sure with finger kneading method(49 ± 11 .8 cm H2 O)was obviously higher than specialized cuff pressure meter group (27 ± 1 .5 cm H2O)and minimum closing volume method group(25 ± 2 .1 cm H2O) .The incidence of tracheal mucosal damage was obviously higher in the group with finger kneading method(87 .5% ) than other groups(20 .0% and 15 .0% respectively) .There were no obvi-ous differences in the incidence of tracheal mucosal damage between the rest two groups (P>0 .05) .Conclusion The cuff pressure in the finger kneading method was higher than the permitted value and it make the incidence of tracheal mucosal damage increase . The cuff inflation with specialized cuff pressure meter and minimum closing volume method can make the cuff pressure properly a-mong the permitted value and decrease the complications related to endotracheal intubation .
