Abstract:
Objective: To compare the sealing pressure of the Baska® Mask (BM) with Proseal® laryngeal mask (PLM) in patients undergoing general anesthesia for a variety of elective non-head and neck surgical procedures. Design: Prospective, randomized, ethical issues committee approved interventional study. Setting: Operating rooms of Khoula Hospital, Muscat (Oman). Methodology: 52 consecutive adult patients of either sex requiring general anesthesia were included in the study. Patients with BMI >30, having known tendency to nausea/vomiting or pharyngeal pathology were excluded from the study. Following uniform induction with propofol 2-2.5 mg/kg, fentanyl 1.0-1.5 μg/kg, and relaxation with cisatracurium 0.1 mg/kg, either BM (n= 30) or PLM (n= 22) was placed. Primary outcome measure was airway seal pressure while secondary outcome measures included device insertion time, number of attempts, leak fraction, duration of use, and laryngopharyngeal morbidity (sore throat, dysphagia, and dysphonia) at 1 hour and 4 hours postoperatively. Data collection was done by a staff member not involved with the study. Results: The mean insertion time was significantly shorter in the BM group as compared to the PLM group (16.43 ± 4.54 vs. 21.45 ± 6.13)(P=0.001). Mean sealing pressure was significantly higher in the BM group (29.98 ± 8.51 vs. 24.50 ± 6.19)(p= 0.013). The leak fraction showed no difference between the devices and it ranged from 5.5-20% and 5-20% in the BM and PLM group respectively. All other studied parameters showed insignificant differences between the two devices. Conclusion: BM takes significantly shorter placement time and provides a better seal as compared to PLM.
