Background: Video laryngoscopy (VL) and direct laryngoscopy (DL) are two approaches to provide secure airway for patients with compromised airways. This study aims to compare the intubation success rate in video laryngoscopy versus direct laryngoscopy in patients with Philadelphia collars. Methods: 172 patients with cervical collars who have undergone general anesthesia were enrolled. After induction of anesthesia for all patients, an oral airway was used to facilitate the ventilation. A VL approach in Group A and DL approach in Group B were used. In order to evaluate the effectiveness of each method, we considered related parameters, including intubation time, the number of intubation attempts, Cormack-Lehane (CL) score, orodental injuries, heart rate, and blood pressure 3 minutes after intubation, oxygen saturation, neck circumference, and BMI. Results: The ratio of first-attempt intubations was not different among the two groups (P = 1.00). The mean [SD] time for intubation was shorter with DL vs VL (p |
