口咽通气管-鼻导管声门前给氧在心肺复苏初期的应用研究

Study on application of supplied oxygen by oropharyngeal airway-nasal cannula at pre glottis in early-stage cardiopulmonary resuscitation(CPR)

目的探讨口咽通气管-鼻导管声门前高流量给氧在心肺复苏初期的应用效果。方法将76例心搏、呼吸骤停患者按接诊顺序分观察组与对照组各38例,观察组采用经口咽通气管-鼻导管声门前给氧,对照组采用简易呼吸囊-面罩加压给氧;比较两组经皮氧饱和度上升时间、胃内容物误吸率、初期复苏成功率。结果经皮氧饱和度上升时间:观察组(153.6±40.2)s,对照组(264.1±45.1)s;胃内容误吸:观察组3例,对照组11例;初期复苏成功率:观察组68.4%,对照组39.5%。结论心肺复苏初期应用口咽通气管-鼻导管声门前给氧,能提供有效通气量,提高复苏成功率。

Objective To study the application of supplied oxygen by oropharyngeal airway--nasal eannula at pre glottis in early--stage CPR. Method Divide 76 patients with heart beat and respiratory arrest into observation group and control group equally according to admission order. Patients in observation are given oxygen by oropharyngeal airway--nasal cannu- la at pre glottis. Patients in control group are given oxygen by simple respirator--pressure oxygen mask. Compare the rising time of SpO2, aspiration rate of gastric contexts and success rate of resuscitation in early stage of the two groups. Result The rising time of SpO2 ：observation group （I 53.6 ± 40. 2）, control group （264.1 ± 45. i）. Aspiration rate of gas- tric contexts： 3 cases in observation group and 11 cases in control group. Success rate of recovery in early stage： 68. 4% in observation group and 39. 5% in control group. Conclusion Supply oxygen by oropharyngeal airway--nasal cannula at pre glot- tis to patients in early--stage of CPR can improve the effective vemilation in order to improve success rate of resuscitation.
