Evaluation of Insertion Characteristics of LMA ProSeal and AmbuAuraGain in Adult Patients under Controlled Ventilation: A Clinical Study.

Background: In clinical practice, supraglottic airway devices such as the Laryngeal Mask Airway (LMA) ProSeal and AmbuAuraGain are often used for airway management under controlled ventilation.

Materials And Methods: One hundred adult patients having elective procedures under general anesthesia with regulated ventilation participated in this clinical research. Patients were divided into two groups at random: Group B (AmbuAuraGain, = 50) and Group A (LMA ProSeal, = 50). Oropharyngeal leak pressure (OLP), insertion time, ease of placement, number of tries, and problems like blood-stained device or sore throat after surgery were all recorded. All insertions were made by anesthesiologists with at least three years of experience, and standard anesthetic procedures were followed.

Results: Group A (LMA ProSeal) had a mean insertion time of 18.5 ± 2.5 seconds, whereas Group B (AmbuAuraGain) had a considerably lower mean time of 14.2 ± 2.1 seconds ( < 0.01). Group B had a greater first try success rate (96%) than Group A (88%). Although Group A's OLP was somewhat higher (26.3 ± 3.5 cmHO) than Group B's (24.7 ± 3.2 cmHO), the difference was not statistically significant ( > 0.05). Sore throat was one of the similar post-operative problems, occurring in 10% of Group B and 12% of Group A ( > 0.05).

Conclusion: In comparison to LMA ProSeal, AmbuAuraGain showed a quicker insertion time and a higher first try success rate, suggesting enhanced usability. On the other hand, post-operative problems and oropharyngeal leak pressure were similar for both devices.
