ABSTRACT
Objective To investigate the feasibility and effect of visualization teaching method using HC visual laryngoscope for the standardized training of endotracheal intubation in emergency department.Methods Forty standard-trainee doctors were divided into two groups randomly.20 standard-trainee doctors in team N were taught using the conventional teaching method of emergency medicine for the standardized training of endotracheal intubation,and the other 20 standard-trainee doctors in team HC were taught by visualization teaching method using HC visual laryngoscope.After 1 month training,comparisons of the success rate of tracheal intubation in airway management simulator,the time consumed for intubation and the number of attempt on successful intubation cases,and the satisfaction score with the teaching mode scored by standard-trainee doctors between the two groups were done.Results The one-attempt success rate and the success rate of tracheal intubation in airway management simulator by the standard-trainee doctors in group HC were significantly higher than those in group N (40％ vs.10％,85％ vs.55％),while the number of attempt and the time consumed for successful intubation were significantly less than those in group N[(1.65±0.61) vs.(2.27±0.66),(79.00±8.35) s vs.(89.36±12.03) s).The satisfaction score with this teaching mode and teaching effect of standard-trainee doctors in group HC were significantly higher than those in group N (8.10±0.74 vs.6.55±1.05,8.15±0.80 vs.6.85±0.91).Conclusions The visualization teaching method with application of HC visual laryngoscope for standardized training of endotracheal intubation in emergency department could improve the success rate and efficiency of tracheal intubation in airway management simulator for standard-trainee doctors,and this teaching method may be better than the conventional teaching method on teaching mode presenting some feasibility.
ABSTRACT
Objective To investigate the clinical application effects of tracheal intubation under general anesthesia guiding by HC visual laryngoscope in combination with fiberoptic bronchoscopy via clinical studies.Methods A total of 348 patients underwent the tracheal intubation under general anesthesia in the hospital between January 2013 and January 2015 were randomly selected and Divided into three groups according to different ways of guiding tracheal intubation.The first group was a simple fiber light guide bronchoscopy to guide the general anesthesia tracheal intubation was set to F group,In the second group,the general anesthesia tracheal intubation was set to H group for the simple HC video.The third group was HC video mirror combined with fiber light guide bronchoscopy to guide the general anesthesia tracheal intubation was set to H+F group.The general condition and intubation conditions such as the time and frequencies of intubation in three groups were recorded respectively.Results The general condition,age,BMI index,thyromental distance,interincisor distance value were similar among three groups.The time needed for intubation was the longest in group F up to (41 ± 11) s.The highest frequency of intubation was in group H with 30 times,and the time of glottis exposure was the longest in group F as (21 ± 9) s.The difference among groups and intra-groups has statistical significance (P＜0.05).Conclusion HC visual laryngoscope in combination with fiberoptic bronchoscopy guiding tracheal intubation under general anesthesia has a good effect in clinical practice,and is worthy of clinical promotion.
ABSTRACT
Objective To investigate the usefulness of HC visual laryngoscope designed for unskilled junior emergency resident doctors in respect of increasing the efficiency and success rate of emergency tracheal intubation.Methods A total of 80 patients needed the emergency tracheal intubation were at first divided into two groups randomly (random number).Patients in group A were operated by junior emergency resident doctors and patients in group B were operated by well experienced attending doctors.Then,the two groups of patients above were divided into two groups randomly (random number).Patients in group N were operated with conventional laryngoscope and patients in group HC were managed with HC visual laryngoscope.Then comparisons of the success rate of glottis exposure,the one-time success rate of tracheal intubation,the success rate of tracheal intubation,the complications,the number of attempt in successful intubation cases and the operative time consumed for successful intubation cases among the groups were done.Results (1)The success rate of glottis exposure,the one-time success rate and the success rate of tracheal intubation in group A-HC were 90%,70% and 90%,respectively which were significantly higher than those (50%,20% and 45%)in group A-N (P 0.05 ). Conclusions HC visual laryngoscope used by unskilled junior emergency resident doctors for emergency tracheal intubation,could increase success rate of glottis exposure,decrease the number of attempt of intubation,decrease rate of complication,shorten operative time required for intubation thus improving efficiency and success rate of emergency tracheal intubation,and maybe narrow the skill gap between unskilled junior resident doctors and well experienced attending doctors in respect of emergency tracheal intubation.
