Background: This prospective, randomized, crossover study had two purposes: first, to determine whether pressure‐controlled ventilation (PCV) is safer than volume‐controlled (VCV) by preventing gastric insufflation in children ventilated through an laryngeal mask airway (LMA); second, assess the measurement of LMA leak pressure (P ) useful for leakage during positive (PPV). Methods: Forty‐one, 2 15‐year‐old underwent general anesthesia with LMA. The expiratory valve was set at 30 cmH O and P measured using constant gas flow. Children were randomly PCV or VCV 5 min order reach a ET CO not exceeding 45 mm Hg, then they alternative mode. If target could be obtained one mode, we switched other. both modes failed, intubated. Tidal volumes, pressures noted compared between modes. Gastric checked epigastric auscultation. Results: provided more efficient VCV, as targeted without all cases except one, whereas failed three cases. No occurred when ventilating below peak. Conclusions: These findings suggest that age group studied, controlled mask. did occur this
