Comparison of Baska Mask Versus Proseal Laryngeal Mask Airway in Elective Surgeries Under General Anaesthesia: A Randomized Clinical Trial

Abstract

BackgroundBaska Mask (BM) is a third-generation supraglottic airway device with a self-inflating cuff. This study aimed to evaluate the efficacy of the BM compared to ProSeal laryngeal mask airway (PLMA) regarding insertion time, ease of insertion, and oropharyngeal seal pressure in patients undergoing elective surgeries under general anesthesia for less than two hours. MethodsThis prospective, randomized, double-blind comparative study was done on 64 patients randomly divided into two groups, with 32 patients in the PLMA group (Group A) and 32 in the BM group (Group B). Individuals with a body mass index (BMI) of more than 30, a history of nausea/vomiting, or pharyngeal pathology were excluded from the trial. After induction with propofol 3-4 mg/kg, fentanyl 1-2 mcg/kg, and the neuromuscular blockade was achieved with atracurium 0.5 mg/kg, patients were inserted with either BM (n= 32) or PLMA (n= 32). The primary outcome measure was the time taken for insertion and ease of insertion. Secondary outcome measures included the number of attempts, oropharyngeal seal pressure (OSP), and laryngopharyngeal morbidity (trauma to lips, blood staining, and sore throat) immediately and 24 hours postoperatively. ResultsDemographic data were comparable and statistically insignificant. Regarding time and ease of insertion, the BM could be inserted in a lesser time of 24±1.136 seconds compared to PLMA which took 28.59±1.682 seconds, with a high success rate in the first attempt which was statistically significant. The BM provided a higher OSP (31.34 +1.638 cmH2O) when compared to PLMA (24.81±1.469 cmH2O) and was statistically significant. Complications associated with insertion trauma to the lip, blood staining, and sore throat were more in PLMA (15.6%, 15.6 %, 9.4%, respectively) compared to the BM (6.3%, 3.1%, 3.1%, respectively), and statistically insignificant. ConclusionBM had higher first-attempt successful insertion with better OSP compared to PLMA in patients under controlled ventilation.

A Comparison between Baska Mask and Endotracheal Tube in Patients Undergoing Gynecological Laparoscopic Surgery

“…BIS was significantly higher in B group compared to E group regarding measurements at baseline, after induction/before laryngoscopy, after laryngoscopy, during intubation/insertion and at 1, 3,5,10,20,30, 40, 50, 60, 90 and 120 min. Peak airway pressure was significantly higher in E group regarding measurements at baseline after induction/before laryngoscopy, after laryngoscopy, during intubation/insertion and at 1, 3,5,10,20,30, 40, 50, 60, 90 and 120 min. Also, leak pressure was significantly higher in E group compared to B group at all times of measurements.…”

“…In terms of the intubation characteristics of the two studied groups, table (5) showed that there was a significant difference between the groups regarding insertion time, but there was no significant difference between studied groups as regards anesthesia time, insufflation time and removal time (Table 5). As regards the postoperative complications, table (6) showed that there was a significant difference between the groups regarding sore throat at 1 hour, 2 hours and 4 hours postoperatively.…”

“…An inlet on the BASKA mask is designed to go into the upper oesophagus. In order to assist clear this region, suction can be attached to the side channels on the dorsal surface of the cuff, which is intended to drive any oropharyngeal contents away from the glottis (5) . These traits may make it less likely that secretions or stomach contents will get into the lungs if they build up in the supraglottic area (6) .…”
