Investigation of Endotracheal Cuff Pressure Changes According to Different Positions in Neurosurgery Cases

Investigation of Endotracheal Cuff Pressure Changes According to Different Positions in Neurosurgery Cases

We aimed to measure the change in cuff pressure in different positions in neurosurgery cases and to investigate the effect of case length on cuff pressure.

It is an observational study, the cuffs of the endotracheal tubes of the patients who were intubated under general anesthesia between February 2023 and May 2023 will be inflated at 25 cm H2O pressure, and then the pressure line and the pilot balloon will be connected to the anesthesia monitor. The cuff pressure of the patient will be measured from the pilot balloon throughout the case and recorded at half-hour intervals. Postoperative sore throat will be evaluated on the VAS scale. Postoperative cough, hoarseness, and dysphagia symptoms will be evaluated.
