Effect of Thermal Softening of Endotracheal Tubes on Perioperative Respiratory Adverse Events in Children Undergoing Adenotonsillectomy: A Randomized Controlled Trial.
Paediatric anaesthesia·September 11, 2026·PMID 42725682
Why it mattersPerioperative respiratory adverse events are a leading cause of morbidity in pediatric adenotonsillectomy, and simple, low-cost preventive strategies are needed. This trial suggests that warming endotracheal tubes to body temperature—requiring no extra equipment or drugs—may reduce laryngospasm and coughing, potentially improving airway safety in this high-risk population.
