Postoperative Memories and Optimal Level of Sedation for Tracheal Intubation Using Fiberoptic Bronchoscopy/Vidolaryngoscopy in Patients With Anticipated Difficult Airway Undergoing Surgery

What this Trial Is About

This research focuses on patients with anticipated difficult airways who need tracheal intubation during surgery. It aims to determine and compare the presence of postoperative memories and sedation levels, measured by the Ramsay scale, during intubation performed with either a fiberoptic bronchoscope or a video laryngoscope. The study also explores how intubation duration and sedation depth relate to patient memories and respiratory depression risks. Patients undergoing surgery will receive tracheal intubation using fiberoptic bronchoscopy or videolaryngoscopy while awake, with intravenous sedation to ease anxiety and provide comfort. Sedation levels may vary according to the Ramsay scale as determined by the anesthesiologist. After confirming intubation, general anesthesia will be administered as per usual care. The study observes two groups based on the intubation method used. Participants will be monitored during the procedure for blood pressure, heart rate, oxygen levels, and sedation depth. Twenty-four hours after extubation, patients will be asked about pain and memories of the intubation using a modified Brice questionnaire. A follow-up telephone interview will assess memories again 30 days after surgery. The main outcome measured is the incidence of postoperative memories at these two time points, along with other adverse effects during the procedure.
