BACKGROUND: No technique can be considered as a gold standard for ventilation during direct laser CO2 laryngeal microsurgery. We evaluated the feasibility of standard ventilation with laser-safe endotracheal tubes (ETTs) and inspired O2 fraction (FiO2) = 0.21 during direct microlaryngoscopy. METHODS: During total intravenous anesthesia, standard mechanical normoventilation was set with FiO2 = 0.21 and 50 mm Hg peak inspiratory pressure limit. If SpO2 was <90% for >2 minutes, FiO2 was increased to 0.3; after 4 minutes it was increased to 0.4; after another 4 minutes, positive end-expiratory pressure (PEEP) could be set at 5 cm H2O; and after another 4 minutes, surgery was stopped if SpO2 remained <90%. RESULTS.: We studied 111 consecutive direct microlaryngoscopies on different patients. Four patients (3.6%) suffered minor intraoperative desaturation. Barotrauma was not observed, PEEP was never applied, and surgery was never stopped. Body mass index was independently predictive of the occurrence of intraoperative desaturation. CONCLUSIONS.: Standard mechanical ventilation with FiO2 = 0.21 through laser-safe ETTs is feasible during direct microlaryngoscopy. |
