Abstract
Aim To evaluate the effect of cooled endotracheal tubes
on the incidence of postoperative sore throat, hoarseness,
coughing, and dysphagia after endotracheal intubation.
Methods This randomized controlled trial enrolled pa
tients undergoing elective surgery under general anesthe
sia with endotracheal intubation at Adana Dr Turgut Noyan
Hospital between April and September 2023. The patients
were randomly assigned to be intubated with endotrache
al tubes refrigerated at +4 °C for 4-6 hours before intuba
tion (n = 66) or with endotracheal tubes kept at the operat
ing room temperature (+20-23 °C) (n = 70). The incidence
of sore throat, hoarseness, coughing, and dysphagia was
recorded at 1, 4, 12, and 24 hours postoperatively.
Results The groups did not significantly differ in the inci
dence of sore throat, hoarseness, and coughing at 1 hour
and 24 hours. They also did not differ in the incidence of
dysphagia at 24 hours.
Conclusion Cooled endotracheal tubes are not superior
to tubes kept at operating room temperature in reducing
postoperative sore throat, hoarseness, coughing, or dys
phagia.
