HC可视喉镜在急诊插管中的应用

目的：探讨HC可视喉镜在急诊紧急插管中的临床使用效果。方法：选取本院急诊科2013年1月-2014年1月收治的80例需采取紧急插管方式的急救患者，按照随机数字表法将其分为观察组和对照组各40例，其中观察组采用HC可视喉镜；对照组采用普通光纤喉镜。观察比较两组患者的气管插管声门暴露时间、暴露声门成功率、插管1次成功率、插管次数、插管时间等，以及两组在插管前后的血氧饱和度、血流动力学指标及插管后的并发症发生情况。结果：观察组的声门暴露成功率100%（40/40）明显高于对照组的67.5%（27/40），声门暴露时间及插管时间分别为（4.13±5.27）s和（28.89±6.03）s，均明显短于对照组的（7.26±6.19）s和（54.46±5.79）s，且插管1次成功率87.50%明显高于对照组的52.50%，插管后3 min的血氧饱和度（83.14±8.17）%明显高于对照组的（75.93±7.48）%，而观察组在插管即刻及插管后3 min的心率及平均动脉压均明显低于对照组，不良反应发生率22.5%（9/40）明显低于对照组的80.0%（32/40），差异均有统计学意义（P〈0.05），而两组术后并发症发生率无明显差异（P〉0.05）。结论：使用HC可视喉镜能够提高插管1次成功率，缩短插管时间，并能够快速改善患者氧合，提高抢救效率，值得临床推广。

The Application of HC Visual Laryngoscope in Emergency Intubation

Objective：To investigate the clinical use effect of HC visual laryngoscope in emergency intubation.Method：80 emergency patients needed emergency intubation way in our emergency from January 2013 to January 2014 were selected,they were divided into the observation group and the control group according to the random number table method,40 cases in each group.The observation group was given HC visual laryngoscope and the control group was given ordinary fiber laryngoscope.The endotracheal intubation glottis exposure time,exposure to the success rate of the glottis,once success rate of intubation,the number of intubation,intubation time of the two groups were compared,and the oxygen saturation,blood dynamics and other indicators of the two groups of patients before and after intubation were compared,and after intubation complication rate of the two groups of patients were compared.Result：The exposure to the success rate of the glottis of observation group was 100%（40/40）,it was significantly higher than 67.5%（27/40）of control group, the endotracheal intubation glottis exposure time and intubation time of observation group were（4.13±5.27）s and（28.89±6.03）s,they were significantly shorter than（7.26±6.19）s and（54.46±5.79）s of control group,once success rate of intubation of observation group was 87.50%,it was significantly higher than 52.50%of control group, oxygen saturation of 3 min after intubation was（83.14±8.17）%,it was significantly higher than（75.93±7.48）%of control group,HR and MAP at intubation and 3 min after intubation of observation group were significantly lower than those of control group,and incidence of adverse reaction was 22.5%（9/40）,it was significantly lower than 80.0%（32/40）of control group,the differences were statistically significant（P〈0.05）.There was no significant difference in the incidence of postoperative complications between two groups（P〉0.05）.Conclusion：Using HC visual laryngoscope can improve once success rate of intubatio
