Background and Goal of Study: Laser ablation is a novel and effective mode of treating airway lesions due to prolong intubation and cancer. Airway management and ventilation is a major concern during this procedure. The aim of this study was to define the role of LMA in ventilating patients undergoing laser treatment of upper airway lesions.
Materials and Methods: This randomized clinical trial was performed on patients undergoing laser ablation of airway lesions. Patients were randomly allocated to two groups; first using LMA and second using rigid bronchoscopy for ventilation. Induction and maintenance of general anesthesia was similar in both groups. Complications, vital signs, and patient and physician satisfaction was recorded.
Results and Discussion: Seventy seven patients were enrolled, among which 45 underwent LMA ventilation and 32 underwent rigid bronchoscopy. Mean age of patients was 51.3±16.8 years and 53 were male. The most common complication was hemorrhage, with no statistically significant difference between two groups. But the most important complication was hypoxemia which was significantly prevalent among the rigid bronchoscopy group
Conclusion(s): Using LMA for airway management during upper airway lesions is not only safe and effective but also lacks flammability and causes less hypoxemia during the procedure.
