Postoperative throat discomfort after using LMA-Proseal versus Profile Soft-Seal Cuff for anesthesia in ambulatory gynecologic laparoscopy

Abstract

Objective: To compare the severity of throat discomfort in terms of sore throat, dysphagia and dysphonia caused by LMA-ProSeal (PLMA) and Profile Soft- Seal Cuff (PSSC) in early (2 hour) and late (24 hour) postoperative period after ambulatory gynecologic laparoscopy. Design: Randomized double-blind controlled trial Setting : King Chulalongkorn Memorial Hospital which is the tertiary care center. Research Methodology: One hundred and thirty-eight patients undergoing ambulatory gynecologic laparoscopy were randomly allocated into 2 groups. The patients in one group were intubated with Profile-Soft-Seal Cuff (PSSC), while the other with ProSeal LMA (PLMA). Four-leveled score of sore throat, dysphagia, dysphonia, nausea or vomiting symptoms at 2 and 24 hour and 5-leveled satisfaction score to both techniques at 24 hour postoperatively were evaluated. Results : The patients in PLMA group have less severe symptoms of sore throat (p = 0.016) and dysphonia(P= 0.003) than those in PSSC group only at 2 but not at 24 hour postoperatively. No difference was detected for dysphagia, nausea, vomiting and satisfaction scores. Conclusion : PLMA caused less sore throat and dysphonia in early postoperative period than PSSC did. PLMA can be used as an alternative airway device for anesthesia in ambulatory gynecologic laparoscopy.
