ABSTRACT
Objective To evaluate the effect of hypothermia on the endotracheal tube cuff pressure during cardiopulmonary bypass in the pediatric patients with congenital heart disease. Methods Forty pedi-atric patients of both sexes, of American Society of Anesthesiologists physical status Ⅱ-Ⅳ, aged 1 months-14 yr, weighing 3-58 kg, scheduled for elective surgery for congenital heart disease using cardiop-ulmonary bypass, were included in this study. All the pediatric patients were intubated with a cuffed endo-tracheal tube. After anesthesia induction and endotracheal intubation, the air was injected into the cuff to make the cuff pressure reach 20 cm H2 O ( baseline) . The endotracheal tube cuff pressure was recorded when the esophageal temperature was reduced to 34, 32, 30, 28 and below 28℃ and returned to 28, 30, 32, 34 and 36 ℃. Results The cuff pressure was significantly decreased when the esophageal temperature was reduced to 30 and 28 ℃ and below 28 ℃ and returned to 28, 30, 32 and 34 ℃ as compared with the baseline ( P<0. 05) . Conclusion Hypothermia can reduce the endotracheal tube cuff pressure during car-diopulmonary bypass, and it is recommended to routinely monitor the cuff pressure in the pediatric patients with congenital heart disease.
