摘　　要：目的探讨胃管误入气管的鉴别方法。方法用水封瓶 (闭式胸腔引流瓶 )测量胃管在胃及气管内的气压。结果胃管在胃内时气压为 ( 1± 0 45 )cmH2 O ,在气管内时为 ( 7± 2 0 3 )cmH2 O(P <0 0 1)。结论在无法从胃管抽出酸性胃内容物 ,难以鉴别胃管是否误入气管时 ,可用水封瓶测压进行鉴别。ObjectiveTo research a way to verify whether the stomach duct is misplaced into the trachea.MethodsThe air pressure of the stomach duct placed in the stomach or in the trachea were measured using a water bottle.ResultsThe air pressure of the stomach duct was (1±0 45)cmH 2O When it was put in the stomach, and was (7±2 03)cmH 2O when it was put in the trachea( P <0 01).ConclusionsWhen it is impossible to draw out acerbic substances from the stomach to verify whether the stomach duct is placed in the stomach or misplaced in the trachea, measure the air pressure stomach duct by a water bottle can be used as substitute, which is reliable and convenient.
