Abstract
With the development of newer polyurethane cuffed endotracheal tubes (cETTs), there has been a shift in clinical practice among pediatric anesthesiologists. Despite improvements in design, excessive inflation of the cuff can still compromise tracheal mucosal perfusion. Several perioperative factors can affect the intracuff pressure (CP), and there is no consensus on safe CP in pediatric patients undergoing repair of congenital cardiac disease (CHD) utilizing cardiopulmonary bypass (CPB). In the current study, the CP was continuously monitored in pediatric patients undergoing surgery for CHD. After IRB approval, this observational study was conducted on pediatric patients who underwent repair of CHD using CPB with a cETT in place. After anesthetic induction and endotracheal intubation, the cuff was inflated using the air leak technique while maintaining a continuous positive airway pressure of 20 cmH2 O. After inflation, the CP was continuously monitored throughout the procedure. In addition, temperature and mean arterial pressure (MAP) were also recorded. The study included 33 patients who ranged in age from 1 month to 15.3 years. Their weight ranged from 4.0 to 83.6 kg. Six patients were excluded from the analysis due to the n...Continue Reading
