Table 3: Ventilatory parameters and complications of patients with simulated fixed cervical spine Note: Data in oropharyngeal leak pressure and peak inspiratory pressure are presented as mean ± SD and were analyzed by Mann-Whitney U test. Data in success rate are presented using Chi-square test. Data in fiberoptic grading are presented as number and were analyzed by Chi-square test. Data in complication are presented using Fischer's exact test. ILMA: Intubating laryngeal mask airway.
