简要总结
This study will involve patients classified as American Society of Anesthesiologists (ASA) I-II at our hospital. Written informed consent will be obtained from all participants. The study will enroll patients with undergoing surgery under general anesthesia . The patients will be randomly assigned to three groups
Group 1 (n=25): awake tracheal intubation through fiberoptic bronchoscope.
Group 2 (n=25): awake tracheal intubation through D blade of cmac videolaryngoscope.
Group 3(n=25):Awake tracheal intubation through channelled kingvision videolaryngoscope.
Outcome measures-
1.The time required for awake intubation using fiberoptic bronchoscope, C-MAC Videolaryngoscope and kingvision videolaryngoscope will be noted. Intubation time in seconds was calculated from insertion of C-MAC videolaryngoscope,kingvision laryngoscope or fiberoptic bronchoscope(FOB) in the mouth till confirmation of ETT was done by capnography.
2.First attempt success rate-Number of patients which could be intubated in a single attempt was recorded in each group.
3. Number of attempts needed for intubation- An intubation attempt was considered unsuccessful if the VL was removed from the oral cavity owing to coughing, gagging, or inability to view the vocal cords.Maximum of three attempts were allowed.
4.Laryngeal view -The laryngeal view was assessed by the percentage of glottic opening (POGO) scale./percentage of glottis opening scale.
5.Ease of intubation.
6.Hemodynamic parameters, which include heart rate (HR), mean arterial blood pressure (MABP), and O2% saturation, will be recorded immediately pre-intubation as baseline reading and then at 1 and 5 min post-intubation.
7.Complications or side effects during intubation such as blood clots on the device due to dental or lip trauma and postoperative sore throat will be noted
