NCT03528590

Brief Summary

Currently, the main method for selecting an i-gel® size is based on the body weight recommendation (30-60 kg for size 3 and 50-90 kg for size 4) according to the manufacturer's recommendation. However, there is an overlapping in size selection in people weighing between 50 and 60 kilograms. Laryngeal mask airways are widely used for breast surgery, and this patient cohort is often weighed between 50-60 kilograms in National Taiwan University Hospital. Therefore, in this randomized clinical trial, the investigators will compare the ventilation efficacy of size 3 and size 4 i-gel® in anesthetized, paralyzed female patients weighing 50 to 60 kilograms who undergo breast surgery. Also, the investigators will record any side effects of size 3 and size 4 i-gel® in this cohort.

Outcome Measures

Primary Outcomes (1)

  • Compare the ventilation efficacy of size 3 and size 4 i-gel® in anesthetized, paralyzed female patients weighing 50 to 60 kilograms who undergo breast surgery.

    Use ventilation score (1 point for presence of each item, a total score from 0 to 3) to evaluate ventilation efficacy. Ventilation score include: 1. Air leak pressure below 15 cm H2O 2. Bilateral chest excursion during inspiratory 20 cm H2O 3. Square wave capnography

    1 day

Secondary Outcomes (1)

  • Compare side effects of size 3 and size 4 i-gel® in anesthetized, paralyzed female patients weighing 50 to 60 kilograms who undergo breast surgery.

    2 days
