Assessment of Endotracheal Tube Temperature Effects in Children Undergoing Adenotonsillectomy

A disposable ETT sized appropriately for the age of the patients will be kept in a 40°C incubator (MIR-162) for 30 minutes. An infrared non-contact thermometer will be used to measure the ETT wall temperature. After removal from the incubator, intubation will be performed as soon as the tubes reach a temperature of 24°C for the T1 group by serial measurements. All intubations will be performed by a single anesthesiologist who is not associated with the study.

An infrared non-contact thermometer will be used to measure the ETT wall temperature. After removal from the incubator, intubation will be performed as soon as the tubes reach a temperature of 37°C for the T2 group by serial measurements.
