Comparison Between two Supraglottic Airway Devices: Ambu AuraGain & Pro Seal LMA

Abstract

Context: Aims: To compare two supra glottic airway devices, Ambu auragain & proseal LMA in terms of their working performance & insertion characteristics during general anesthesia in patient undergoing elective laparoscopic surgery. Settings and Design: After written informed consent, 60 patients of ASA I & II, aged 18 to 60 years, of either gender posted for laparoscopic surgery under general anesthesia were included in the study. Patients were divided into two groups of 30 patients each. Methods and Material: In group A: airway was secured with Ambu Auragain & in group P: with Proseal LMA for general anesthesia. Working performance (in terms of oropharyngeal leak pressure) and insertion characteristics (insertion time, manipulations of device, number of attempts) were recorded at the time of induction. Haemodymanics (Heart rate, mean arterial blood pressure, SpO2) & complications (if any) were recorded perioperatively. Statistical Analysis used: Student t test for quantitative data & Chi square test for qualitative data. Results: Oropharyngeal leak pressure was significantly higher & insertion time was significantly less in group A compared to group P (P<0.0001). There was no statistically significant difference in insertion characteristics, demographic data, haemodynamics, ease of orogastric tube & post operative complications in both the groups. Conclusions: AmbuAuragain provides higher oropharyngeal leak pressure with lesser insertion time compared to ProSeal LMA.>>0.0001). There was no statistically significant difference in insertion characteristics, demographic data, haemodynamics, ease of orogastric tube & post operative complications in both the groups. Conclusions: AmbuAuragain provides higher oropharyngeal leak pressure with lesser insertion time compared to ProSeal LMA.
