Abstract
INTRODUCTION: The objective of this study was to compare the practicality and efficacy of utilizing a view-adjustable video laryngeal mask (SafeLM) versus endotracheal intubation (ETI) in the context of arthroscopic shoulder surgery. PATIENTS AND METHODS: A randomized controlled trial enrolled 100 patients undergoing arthroscopic shoulder surgery, randomly assigned to the SafeLM group (n = 50) or ETI group (n = 50). The primary outcome measure was hemodynamic parameters, while mechanical ventilation parameters, complications, and the quality of anaesthesia recovery were considered as secondary outcomes. These parameters were then compared between the two groups. RESULTS: During the intubation and extubation procedures, the SafeLM group demonstrated significantly lower mean arterial pressure and heart rate compared to the ETI group (p < 0.001). Furthermore, the airway pressure at T(2) and T(3) was notably lower in the SafeLM group compared to the ETI group (p < 0.001). However, there were no statistically significant differences in oxygen saturation observed between the two groups at any time point. Both groups were equally capable of quickly establishing a surgical airway when necessary. Notably, a smaller proportion of patients in the SafeLM group exhibited negative reactions during tube removal. Additionally, there was a statistically significant difference in the occurrence of post-operative sore throat, difficulty swallowing, choking, and coughing between the two groups (p < 0.001). CONCLUSIONS: The utilization of SafeLM may result in enhanced regulation of blood pressure and heart rate among patients who undergo arthroscopic surgery for the shoulder while in the side decubitus position.
