The purpose of this study was to compare the effectiveness of the trapezius squeezing test with that of the jaw thrust maneuver as clinical indicators of adequate conditions for laryngeal mask airway (LMA) insertion 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 SpO(2) < 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).
The trapezius squeezing test is a superior indicator of an adequate condition for LMA insertion compared to the jaw thrust maneuver in adults under sevoflurane anesthesia.
本研究旨在比较斜方肌挤压试验与下颌推挤手法作为七氟醚麻醉下成人喉罩置入充分条件的临床指标的有效性。
100 例 ASA 身体状况 1 或 2 级的择期行小手术的成年患者随机分为 T（斜方肌挤压组，n = 50）组或 J（下颌推挤组，n = 50）组。在失去对斜方肌挤压或下颌推挤的反应后，立即插入喉罩。记录成功和不成功的尝试。不成功的尝试定义为在插入喉罩时发生咳嗽、呛咳、明显的有目的运动、屏气、喉痉挛或 SpO2 < 90%。记录插入时间、呼气末七氟醚浓度、平均动脉压和心率。
T 组的成功尝试发生率明显高于 J 组（分别为 48/50 比 36/50）。
在七氟醚麻醉下的成人中，斜方肌挤压试验是喉罩置入充分条件的一个比下颌推挤手法更好的指标。
