The application of HC visual laryngoscope used for emergency tracheal intubation on obese patients in Emergency Department / 中华急诊医学杂志

ABSTRACT

Objective To investigate the effect and application value of HC visual laryngoscope used for the emergency tracheal intubation on obese patients in the Emergency Department. Methods Totally 80 obese patients enrolled from January 2014 to December 2016 from Emergency Department, Second affiliated hospital of Xi'an Jiaotong University who needed the emergency tracheal intubation were randomly (random number) divided into two groups. Patients in group T were operated with traditional laryngoscope, and patients in group HC with HC visual laryngoscope. Then the success rate of glottis exposure, the trial times, operative time, success rate and complication rate of tracheal intubation were compared between the two groups. Results The success rate of glottis exposure in group HC was significantly higher than that in group T (95％ vs 77.5％, P<0.05). The one-time success rate of tracheal intubation and the total success rate of tracheal intubation in group HC were significantly higher than those in group T (72.5％ vs 37.5％, and 95％ vs 62.5％, respectively, P<0.05). However, the trial times of successful intubation cases and the operative time of successful intubation cases were significantly less than those in group T (1.26±0.40) vs (1.64±0.82), and (30.74±6.17) s vs (44.2±7.68) s, respectively, P<0.05. The complication rate of tracheal intubation in group HC was significantly less than that in group T (12.5％ vs 35％, P<0.05). Conclusions HC visual laryngoscope used for the obese patients in Emergency Department can not only increase the success rate of glottis exposure, decrease trial times and shorten operative time of intubation, but also improve the success rate and decrease the complication rate of emergency tracheal intubation, thus having a certain application value.
