RESUMO
The clinical data of 96 intubated inpatients with restricted cervical movement from June 2012 to June 2014 were retrospectively reviewed.They were divided into fiberoptic bronchoscope, Shikani optical stylet and McCoy laryngoscope groups (n =32 each).Identical anesthesia induction was applied.Compared with McCoy laryngoscope group, the total success rate and one-time success rate of tracheal intubation was higher in Shikani optical stylet group, tracheal intubation time was shorter and postoperative complications were fewer (P ＜ 0.05).Compared with group F, endotracheal intubation time was shorter (P ＜0.05).However, heart rate, mean arterial pressure (MAP), oxygen saturation (SpO2), total success rate of tracheal intubation, one-time success rate of tracheal intubation and complication rate showed no significant inter-group differences at all timepoints (P ＞ 0.05).Shikani optical stylet intubation has a less impact on hemodynamics and intubation time is short so that it is ideal for surgical patients with restricted cervical spine.
