Abstract

Background. This study aimed at comparing the effects of cylindrical- and conical-cuff endotracheal tubes (ETTs) inflated with saline on cuff pressures, post-operative sore throat, and post-operative analgesic consumption in surgeries taking longer than 120 min.


Objective. This study aimed at comparing the effects of cylindrical- and conical-cuff endotracheal tubes (ETTs) inflated with saline on cuff pressures, post-operative sore throat, and post-operative analgesic consumption in surgeries taking longer than 120 min.


Methods. The study was performed on a total of 100 patients, aged 18-65 years, in the ASA I-III risk group, with cylindrical cuff (Group C, n = 50) and conical cuff (Group T, n = 50) ETT patients. Cuff pressure values of all patients were recorded.


Results. The cuff pressure values at all measurement times and maximum cuff pressure value were significantly lower in Group T than in Group C (p < 0.05). In the post-operative 24-h period, sore throat and total analgesic consumption were significantly lower in Group T than in Group C (p < 0.05).


Conclusion. conical cuff ETTs prevent the increase in intraoperative cuff pressures, reduce the incidence of post-operative sore throat, and accordingly reduce post-operative analgesic consumption compared to cylindrical cuff ETTs.
