Comparison of the trapezius squeezing test and jaw thrust as indicators for laryngeal mask airway insertion in adults
Korean Journal of Anesthesiology, 10/20/2011
Chang CH et al. – The trapezius squeezing test is a superior indicator of an adequate condition for laryngeal mask airway (LMA) insertion compared to the jaw thrust maneuver in adults under sevoflurane anesthesia.
One hundred adult patients of ASA physical status 1 or 2 undergoing minor surgical procedures were randomly allocated to the T (trapezius squeezing, n=50) group or the J (jaw thrust, n=50) group.
The LMA was inserted immediately after the loss of response to trapezius squeezing or jaw thrust.
Successful and unsuccessful attempts were recorded.
An unsuccessful attempt was defined as the occurrence of coughing, gagging, gross purposeful movements, breath-holding, laryngospasm, or an SpO2<90% during LMA insertion.
Insertion time, end-tidal sevoflurane concentration, mean arterial pressure, and heart rate were recorded.
The incidence of successful attempts was significantly higher in the T than in the J group (48/50 vs. 36/50, respectively).
