What this Trial Is About
Researchers are comparing two methods of endotracheal intubation—video laryngoscopy and direct laryngoscopy—to see which technique better controls the body's stress response and how quickly intubation can be performed. This single-blind study focuses on patients undergoing elective surgeries requiring intubation, aiming to measure changes in heart rate and blood pressure after intubation. Participants will be randomly assigned to either the video laryngoscope group using the Besdata (BD-M7) Portable Video Laryngoscope with a curved rigid stylet or the direct laryngoscope group using a traditional blade. Both groups will receive the same anesthesia protocol including premedication and induction drugs, with intubation performed by experienced anesthetists. The time from blade insertion to confirmation of tube placement will be recorded along with vital signs. Throughout the procedure, vital signs including blood pressure, heart rate, oxygen saturation, and ECG will be monitored before anesthesia induction, after induction, during bag-mask ventilation, and at several points after intubation. The main outcomes measured are heart rate and various blood pressure readings during the perioperative period, with secondary focus on the duration of laryngoscopy. Data will be analyzed to compare stress responses and intubation times between the two techniques.
