Abstract

The aim of the study was to compare the effectiveness of the Classic laryngeal mask airway with AMBU laryngeal mask airway in adults undergoing minor surgical procedures. Methods:. A total of 60 patients aged 18 to 60 years scheduled for elective minor surgical procedures requiring general anesthesia were randomly divided into 2 groups- LMA Classic and LMA Ambu whose airway were secured with the corresponding devices. Standard general anaesthesia technique with spontaneous breathing was maintained in both groups. The following parameters were studied- ease of insertion (number of attempts), time taken for insertion, hemodynamic response to insertion and incidence of any complications Results: The Ease of insertion was superior for the AMBU LMA compared to the Classic LMA. The number of attempts needed for successful insertion of Classic LMA was higher than that of AMBU LMA, with a p-value of 0.0236, which is statistically significant. The time taken for insertion of AMBU LMA was shorter compared to Classic LMA, with a p-value of 0.001, which is statistically significant. Hemodynamically, there was a significant difference between the two groups regarding systolic blood pressure, diastolic blood pressure, and mean arterial blood pressure after insertion. Ambu LMA was found to have better hemodynamic stability compared to classic LMA. Blood staining on AMBU LMA and Classic LMA were comparable and not statistically significant. The Incidence of postoperative sore throat was comparable and not statistically significant between Ambu LMA and Classic LMA. Conclusion: AMBU LMA is superior in comparison to Classic LMA as it has potential advantages like being easier and quicker to insert, having a higher success rate at the first attempt, and causing less hemodynamic response and less airway trauma.
