Clinical Significance of Video Laryngoscopes in Application for Patients with Difficult Airway Intubation

Objective To explore the clinical significance of video laryngoscopes in patients with difficult airway intubation. Methods A total of 40 patients with difficult airways,who would undergo endotracheal intubation,during January2011 and August 2012 were randomly divided into study group( n =20) and control group( n =20). The study group underwent endotracheal intubation under video laryngoscopes,while the control group underwent direct laryngoscopy and tracheal intubation. The values of mean arterial pressure( MAP) and heart rate( HR) were monitored,and intubation time and the incidence rates of complications in the two groups were also recorded. Results Compared with those before the induction in the same group,the values of MAP and HR at the time of intubation in the two groups significantly decreased( P 0. 05),but there was no statistically significant difference between the two groups( P 0. 05); at the time of intubation finish,values of MAP and HR in study group returned to normal,and the values were significantly decreased compared with those in control group( P 0. 05),while the values in control group were significantly higher than those before induction( P 0. 05). Compared with those in control group,the total intubation time and the best glottal opening time were significantly reduced,intubation time through the mouth was significantly prolonged and incidence rates of complications were significantly lower,and the differences were statistically significant( P 0. 05). Conclusion Endotracheal intubation under video laryngoscopes is safe and effective and can improve intubation success rate in patients with difficult airway.
