Changes in Endotracheal Tube Cuff Pressure during Cardiac Surgery.
J Coll Physicians Surg Pak Jan ;10(2):64-6.

This prospective study was conducted, to measure the changes in endotracheal tube cuff pressure [ETCP] and to find out its correlation with body temp during cardiac surgery, in 50 patients selected for open heart surgery. All the patients were kept on cardiopulmonary bypass machine [CPB] and their body temperature was brought down to a mean temp of 28 degree centigrade during surgery, these patients were intubated with BAXTER high volume, low pressure cuffed endotracheal tubes [ETT]. Standard anaesthesia technique was used to anesthetize the patients. Endotracheal tube cuff pressures [ETCP] were measured with Portex Cuff Inflator / Pressure Gauge. Significant changes in ETCP were noted during hypothermia and rewarming.
