【摘要】：目的研究避免喉罩通气罩过度充气的两种培训方法的有效性。方法将41名麻醉医生采用随机数字表法分为手感判断组(H组,n=20)和短期压力表学习组(G组,n=21)。培训前两组受试者对Supreme喉罩进行充气,目标压力为30 cm H2O和60 cm H2O,由研究者用压力表测定通气罩的实测压。H组接受手感判断法培训,左手无名指分别轻触并体会唇红和鼻尖的软硬度,套囊软硬度与唇红相当定义为30 cm H2O,与鼻尖相当定义为60 cm H2O。G组采用压力表对套囊进行充气,体会通气罩压力分别为30 cm H2O和60 cm H2O时套囊的软硬程度。培训1周后再次进行喉罩充气试验并记录培训后通气罩实测压。比较两组受试者培训前后通气罩实测压之间的差异。结果通气罩目标压力为30 cm H2O时,两组培训后实测压均显著低于培训前[H组:(39.7±15.7)cm H2O比(59.7±30.7)cm H2O,P=0.00;G组:(26.2±13.2)cm H2O比(70.6±27.9)cm H2O,P=0.03],组间差异无统计学意义(P=0.60);目标压力为60 cm H2O时,H组实测压显著高于G组[(91.1±24.3)cm H2O比(58.1±15.4)cm H2O,P=0.01)]。结论通气罩目标压力为30 cm H2O时,两种培训方法均可显著改善受试者的喉罩充气效果。目标压力为60 cm H2O时,短期压力表培训效果优于手感判断法培训。
[Abstract]:Objective to study the effectiveness of two training methods to avoid overinflating laryngeal mask. Methods 41 anesthesiologists were randomly divided into two groups: group H (group H, n = 20) and group G (group G, n = 21). Before training, two groups of subjects inflated the Supreme laryngeal mask, the target pressure was 30 cm H 2O and 60 cm H 2O. The pressure gauge was used to measure the actual pressure of the hood. The soft and hard degree of lip red and nose tip of the left ring finger was lightly touched and realized. The soft and hard degree of the sleeve capsule was defined as 30 cm H _ 2O with the lip red degree, and that with the nose tip was defined as 60 cm H2O.G group. The pressure gauge was used to inflate the sleeve capsule. To understand the soft and hard degree of the sheath when the pressure of the ventilator is 30 cm H 2O and 60 cm H 2O, respectively. After 1 week of training, the laryngeal mask inflation test was conducted again and the measured pressure of the ventilator after training was recorded. To compare the difference of the measured pressure between the two groups before and after training. Results when the target pressure of the ventilator was 30 cm H2O, The measured pressure of two groups after training was significantly lower than that before training [group H: (39.7 卤15.7) cm H _ 2O: (59.7 卤30.7) cm H _ 2O P0. 00G group: (26.2 卤13.2) cm H _ 2O ratio (70.6 卤27.9) cm H _ 2O P _ 2O 0.03], there was no significant difference between the two groups (P0.60), and the measured pressure of H group was significantly higher than that of G group when the target pressure was 60 cm H _ 2O [(91.1 卤24.3) cm / H _ 2O ratio (58.1 卤15.4) cm H _ 2O P _ (0.01)]. Conclusion when the target pressure of ventilator is 30 cm H2O, the two training methods can significantly improve the inflating effect of laryngeal mask. When the target pressure is 60 cm H2O, the training effect of short-term pressure gauge is better than that of handle judgment method.
