2种不同方法为留置气管导管患者插胃管的效果研究

目的探讨提高留置经鼻气管导管的患者插胃管成功率的方法，缩短插管时间，减轻患者不适。方法选择70例已经经鼻留置气管导管的患者，随机分为观察组38例和对照组32例，观察组操作者插胃管至18～20cm时，由另一位护士把气管导管气囊内的气体全部抽出，继续将胃管送入胃内并确认后，再将气管导管气囊充气；对照组采用插胃管过程中不放出气囊内的气体，气囊保持充盈状态的插胃管术。比较2组第1次插管成功率及所需插管时间。结果观察组第1次插胃管的成功率显著高于对照组（P〈0．05），观察组插管时间显著少于对照组，差异有统计学意义（P〈0．01）。结论观察组采用的插胃管方法不仅提高插管成功率，又大大减少插管时间，从而减轻患者的痛苦，值得临床借鉴。

Application research on two different methods for stomach tube insertion for patients with indwelling nasotrachcal tube

Objective To discuss the method to increase the success rate of stomach tube insertion for patients with indwelling nasotracheal tube in order to shorten the time of insertion operation and reduce the discomfort of patients. Methods Seventy patients with nasotracheal tube were randomly divided into the observation group（38 cases） and the control group（32 cases）.When the operator for the observation group inserted stomach tube to 18-22 centimeters deep,the nurse pumped the gas out from the tracheal catheter aerocyst.After the stomach tube reached stomach the tracheal catheter aerocyst was aerified again.The control group did not release the gas from tracheal catheter aerocyst when inserting the stomach tube.The first intuhation success rate and time needed for intuhation were compared be- tween the two groups. Results The first intuhation success rate of the observation group was higher than that of the control group （P 〈 0.05 ）.While the time needed for intubation was shorter than that of the control group （P 〈 0.01 ）. Conclusions Method used by the observation group not only increased the first intubation success rate,but also shortened time needed for intubation.This method can alleviated pain of patients and worth applying widely in clinic.
