Objective: To compare the application of the SaCo visual laryngeal mask and the WORK laryngeal mask in adult laparoscopic surgeries under general anesthesia, and to assess their effects on postoperative pharyngolaryngeal discomfort.
Methods: A retrospective analysis was conducted on 90 adult patients who underwent elective laparoscopic surgery under general anesthesia between June 2022 and April 2024. Based on the airway device used, patients were divided into the control group (n=45, WORK laryngeal mask) and the observation group (n=45, SaCo visual laryngeal mask). The two groups were compared in terms of laryngeal mask insertion parameters (seal pressure, insertion time, first-attempt success rate, number of adjustments > 2 times, peak airway pressure, endoscopic visibility grading, positioning accuracy, removal time), vital signs (heart rate, mean arterial pressure), perioperative outcomes (post-extubation time, time to regular diet, postoperative hospital stay), VAS-based pharyngolaryngeal discomfort scores, and complication rates.
Results: The observation group demonstrated significantly higher airway seal pressure at insertion, 1 hour, and 2 hours post-insertion (P< 0.05). Adjustment rate > 2 times was significantly lower, while positioning accuracy was significantly higher (P< 0.05). No significant differences were found in heart rate or mean arterial pressure between groups. The observation group had significantly shorter post-extubation time, earlier diet resumption, and shorter hospital stays (P< 0.05). Pharyngolaryngeal discomfort scores at 1, 3, and 7 days post-surgery were significantly lower in the observation group (P< 0.05). The complication rate was also lower in the observation group (4.44%) than in the control group (20.00%) (P< 0.05).
Conclusion: Compared to the WORK laryngeal mask, the SaCo visual laryngeal mask offers better sealing and placement accuracy, reduces pharyngolaryngeal discomfort, and promotes faster postoperative recovery with fewer complications.
