“…Use of muscle relaxants, as we did in our study, decreases the tone of laryngeal and pharyngeal muscles and reduces the OLP of supraglottic airway (SGA) devices.

“…[ 2 13 14 15 16 17 ] OLP depends on the seal between cuff of SGA, laryngeal inlet, and the surrounding soft tissues of perilaryngeal area. [ 12 ] The anatomically shaped and pliable nature of i-gel's cuff may be able to conform to the patients’ laryngeal anatomy well despite patients’ excess perilaryngeal soft tissue. Excess perilaryngeal soft-tissues pushing i-gel's cuff more effectively against the laryngeal inlet may lead to better seal between the cuff of i-gel and laryngeal inlet in obese patients.…”

The supraglottic airway device (SAD) is an appropriate alternative to tracheal intubation because of its advantages such as stable hemodynamics and decreased airway morbidity. It also helps to maintain adequate ventilation in laparoscopic surgery, with increased peak airway pressure (PAP) under general anesthesia [1,2]. The i-gel Ⓡ (Intersurgical Ltd., UK) is widely used for laparoscopic surgeries [1,3-5]. However, the Baska Mask Ⓡ (Logikal Health Products PTY Ltd., Australia), first introduced in 2012, provides more efficient ventilation by automatically inflating the cuff during positive pressure ventilation. The cuff differs from other non-inflatable cuffs in that it is continuous with the cen-Clinical Research Article Background: The supraglottic airway device is an appropriate alternative to tracheal intubation in laparoscopic surgery. We compared the Baska Mask Ⓡ with i-gel Ⓡ by measuring the oropharyngeal leak pressure (OLP) and hemodynamic and respiratory parameters during laparoscopic cholecystectomy. Methods: A total of 97 patients were randomly allocated to either i-gel group (n = 49) or Baska Mask group (n = 48). Insertion time, number of insertion attempts, fiber-optic view of the glottis, and OLP were recorded. Heart rate, mean arterial pressure, peak airway pressure (PAP), lung compliance, and perioperative complications were assessed before, during, and after pneumoperitoneum. Results: There were no significant differences between the two groups regarding demographic data, insertion time, fiber-optic view of the glottis, and the use of airway manipulation. The OLP was higher in the Baska Mask group than in the i-gel group (29.6 ± 6.8 cmH 2 O and 26.7 ± 4.5 cmH 2 O, respectively; P = 0.014). Heart rate, mean arterial pressure, PAP, and lung compliance were not significantly different between the groups. The incidence of perioperative complications was small and not statistically significant. Conclusions: Both the i-gel and Baska Mask provided a satisfactory airway during laparoscopic cholecystectomy. Compared with the i-gel, the Baska Mask demonstrated a higher OLP.

Does prewarming of i-gel improve insertion and ventilation in anaesthetised and paralysed patients? A prospective, randomised, control trial

et al. 2019

Context: I-gel are supraglottic airway devices with non-inflatable gel-like cuff that is believed to mould to body temperature, to seal the airway. Hence a pre-warmed i-gel may seal faster, provide better ventilation and superior leak pressure. Aims: To determine if pre-warming i-gel to 40°C improves insertion and efficacy of ventilation. Methods and Materials: A prospective, randomised, controlled trial was done on 64 patients requiring anaesthesia with muscle relaxation for short duration. For those in group W, i-gel warmed to 40°C for 15 minutes before insertion was used, whereas for those in group C, i-gel kept at room temperature (approximately 23°C) was used. The airway sealing pressure over time, number of attempts and time taken for a successful insertion were noted. Statistical Analysis: Mean sealing pressure between two groups was compared using independent sample t -test. Repeated Measures ANOVA was used to analyse mean sealing pressure at 0, 15 and 30 min. P value ≤0.05 was considered statistically significant. Results: Sealing pressure improves over time in both the groups but the mean sealing pressure was higher in group C when compared to group W at all points of time, however this was clinically and statistically insignificant. Ease of insertion, time for successful insertion, insertion attempts, intra-operative manoeuvres were all comparable between the groups with no adverse effects. Conclusions: Pre-warming of i-gel to 40°C does not improve the success rate of insertion or provide a higher sealing pressure in anaesthetised and paralysed patients when compared to i-gel at room temperature.
