Application of Shikani optical stylet to orotracheal intubation in critically conscious patients / 中华急诊医学杂志

ABSTRACT

Objective To investigate the practical value of Shikani optical stylet used for orotracheal intubation in critically conscious patients and to evaluate the successful rate. Method A total of 48 conscious patients with severe respiratory failure were selected from January 2008 to June 2009. Of them, there were 31 males and 17 females,aging 21-86 years old with an average of 57 years old. All enrolled patients needed endotracheal intubation for mechanical ventilation support, and they were assigned to Shikani group (group S, n = 25) and Macintosh group (group M, n = 23) according to the odd and even number of date of admission to this study. The time consumed for intubation, the number of failure in intubation, the adverse effects or complications such as hemodynam-ic changes, injury to the pharyngo-oral cavity, choking and breath-hold were observed and recorded. The rank test and chi-square test were used for statistical analysis. Results The ratio of the successful intubation at first attempt was much higher in group S (96.0%) than that in group M (60.9%) (P <0.01). Compared with group M, the time consumed for intubation was significantly shortened, the cardiovascular reactions were much mild, and the incidence of injury to pharyngo-oral cavity, choking and breath-hold were less in the group S ( P < 0.01 all). Conclusions For the acute and critical patients, especially the conscious ones, orotracheal intubation with the Shikani optical stylet is rapid, successful, safe and less injurious, resulting in mild cardiovascular reactions.
