利多卡因在气管切开患者吸痰中的应用

Application of Lidocaine in Aspiration of Sputum in Patients Receiving Tracheostomy

目的减轻气道吸引时给患者带来的痛苦及不良反应。方法将63例气管切开意识清醒患者随机分为观察组32例和对照组31例。对照组用常规方法进行气道内吸引，观察组吸引前用2％利多卡因0．5～1m1沿气管内壁缓慢注入，待2～3min后再行气道内吸引。结果观察组与对照组在发生刺激性咳嗽、躁动等方面存在统计学显著差异（P〈0．01）；在吸痰时与吸痰后2min，血氧饱和度读数均值两组存在统计学显著差异（P〈0．01）；吸痰后5min血氧饱和度读数均值两组存在统计学差异（P〈0．05）。结论在气道内吸引前用2％利多卡因气道内注入，明显减轻机体的反应，降低对气管的刺激性，减轻了患者的痛苦。

Objective To relieve the pain and discomfort in patients receiving tracheotromy during airway sputum suction. Methods Sixty-three conscious patients receiving tracheostomy were ran- domly divided into 2 groups ： observation group （ n ： 32） and control group （ n ： 31 ）. Patients in control group were given routine airway sputum suction and those in observation group were given 20/00 lidocaine （0.5-1 ml） 2-3 min before airway suction. Results There were significant differ- ences in the irritant cough and restlessness between the 2 groups （ P〈0. 01）. There was significant difference in oxygen suturation rates in 2 groups during suction, two minutes after suction（ P〈0. 01） ,and 5 min after suction（ P〈0.05）. Conclusion Application of 2% lidoncaine in airway tract before suction can markedly reduce tissue reaction and stimulation to the trachea, relieving the sufferings of patients.
