A randomized, single-blinded, prospective study that compares complications between cuffed and uncuffed nasal endotracheal tubes of different sizes and brands in pediatric patients

Abstract Study Objective To compare any association between the problematic distal placement of cuffed and uncuffed nasal endotracheal tubes (NETTs) of different sizes and brands in pediatric patients. Design Randomized, single-blinded, prospective study. Setting Operating room at The Children's Hospital. Patients Pediatric patients (aged 2-18 years) scheduled for dental surgery under general anesthesia whose American Society of Anesthesiologists physical status is not greater than 2. Intervention Patients were randomly assigned to preformed cuffed (1) RAE (Ring-Adair-Elwyn) endotracheal tube by Mallinckrodt or (2) nasal AGT NETT by Rüsch. Measurements The distance between the tube's distal end and the carina was measured using a fiber optic bronchoscope. Problematic placements were defined where the tip of the tubes was within 0.5 cm of carina. Main Results The odds of a problematic placement was 7 times higher (95% confidence interval of odds ratio, 2.06, 23.4) in patients managed with cuffed tubes than those with uncuffed tubes (P =.002). The distance between the tip of cuffed NETT tubes and carina was significantly less than with uncuffed tubes. Conclusions The chances of possible complications were significantly higher with cuffed NETT. The NETT should be kept at least 0.5 cm above carina to avoid possible complications.
