Summary

Increased or decreased intracuff pressures (ICPs) of cuffed endotracheal tubes (cETTs) can lead to many morbidities.The ICPs of cETTs can be changed by the the patients' ear and head\&neck surgery positions. We performed this study to show the effect of the routine combination of neck positions on ICP whilst ear and head\& neck surgeries.

A total of 90 patients were enrolled to the study. Groups 1 and 2 included the patients who underwent right and left ear surgeries, respectively. Group 3 included all patients undergoing head and neck surgery.After the general anesthesia induction, the patients were given a neutral position.The first ICP was measured and adjusted to 18,4 mm Hg (25 cmH2O) at neutral position. Left or right neck rotation was applied to Group 1 or 2 in conformity with the ear operation site and ICP value was documented. Gel pillow with the height of 4,5 cm was placed under the shoulders of Group 3 patients to extend the neck and the ICP was noted. Then, right or left neck rotation was applied depending on the operation side and ICP was documented again. Additionally, ICP values were monitorized continuously in all patients during the surgeries, and documented at 15th, 30th, 60th and 90th minutes at related positions and just before extubation at neutral position. If the ICP value fell below 14,7 mmHg (20 cmH2O) or rose above 22 mmHg (30 cmH2O), ICP was adjusted to 18,4 mm Hg (25 cmH2O) again.
