简要总结
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.
详细描述
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.

研究组 & 干预措施
standard
In the neck flexed and the head extended position, hold mask like a pen with the index finger placed anteriorly at the junction of the cuff and tube, push the mask backwards maintaining pressure against the palate until resistance is felt.
rotational
After insertion of the entire cuff inside the mouth, the LMA FlexibleTM was rotated counter-clockwise through 90° and was advanced through the right side of the tongue until the resistance was felt, and then was returned back in the hypopharynx.
