90° Rotation Technique for LMA FlexibleTM Insertion

Comparison of Standard Versus 90° Rotation Technique for LMA FlexibleTM Insertion

NCT03028896•Seoul National University Bundang Hospital

Summary

The 90° rotation technique is known to improve the success rate of conventional LMA but its effect in LMA FlexibleTM is not known. We tried to find if 90° rotation technique could increase the first attempt success rate of the insertion of LMA FlexibleTM compared to standard technique.

Detailed Description

One hundred and sixteen adult patients undergoing breast surgery were randomized to the two insertion techniques. The ease of insertion was assessed by the success rate at the first attempt. Heart rate and mean blood pressure were recorded 1 min before and 1 min after insertion. Postoperative complications were checked.
