The Effect of Esophageal Temperature Probe Insertion on Tracheal Cuff Pressure

The Effect of Esophageal Temperature Probe Insertion on Tracheal Cuff Pressure

The goal of this prospective observational study is to investigate the effect on esophageal stethoscope insertion on tracheal cuff pressure during general anesthesia.

It is well known that cuff pressure of tracheal tube should not be over 30 cmH2O. Therefore, anesthesiologists usually pay attention to maintain adequate cuff pressure, especially just after completion of tracheal intubation. Recently, esophageal stethoscope is widely used for exact monitoring of patient's body temperature. However, inserting of foreign body in esophagus could affect on the cuff pressure.

The goal of this prospective observational study is to investigate the effect on esophageal stethoscope insertion on tracheal cuff pressure.
