Comparison of Peri-intubation Oxygenation Values and Complications in Patients Intubated With the Delayed Versus Rapid Sequence Intubation Protocols

This study compares two different methods of helping patients breathe by placing a tube in their airway (intubation) in an emergency setting. These methods are called Rapid Sequence Intubation (RSI) and Delayed Sequence Intubation (DSI). The study focuses on adult patients who are still breathing on their own but need a breathing tube for medical reasons not related to an injury (non-trauma). The main goal of the research is to compare: * Oxygen levels before and after the procedure. * The patient's vital signs (such as heart rate and blood pressure). * The number of attempts needed to successfully place the tube and the time the procedure takes. * Blood gas results and any complications that occur during or shortly after the procedure. * Early survival (mortality) rates. While there are previous studies on trauma patients or small observational reports, there is currently no large-scale, multicenter randomized controlled trial that includes all non-trauma adult patients. What makes this study unique? Confirmation of Tube Placement: Researchers will use a specific measurement called end-tidal CO2 (etCO2) to confirm the tube is in the right place, a method not used in similar previous studies. Assessing Difficulty: This study will use the Cormack-Lehane classification system to measure how difficult the intubation was for each patient. Standardization: For the first time, breathing machine (ventilator) settings will be standardized for all patients in this type of study. Real-World Practice: By involving all emergency department physicians as practitioners, the study aims to show how these methods work across a wide range of medical teams.

Two Video Laryngoscopes (Laringocel® and C-MAC®) for First-Attempt Intubation in Adults Undergoing Elective Surgery

This study will test two video laryngoscopes that help doctors place a breathing tube during surgery. A breathing tube is needed for people who receive general anesthesia so they can breathe safely. Video laryngoscopes use a small camera to give a better view of the throat and vocal cords, which may help the tube go in on the first try. The purpose of this research is to find out if a Colombian device called Laringocel® works as well as the widely used international device C-MAC D-Blade® (Karl Storz). If Laringocel® performs similarly, it could be a more affordable option for hospitals with limited resources. 252 adults (126 in each group) who need elective surgery at Alma Máter Hospital de Antioquia (Medellín, Colombia) will take part. Each participant will be randomly assigned, like flipping a coin, to have their breathing tube placed with either Laringocel® or C-MAC D-Blade®. Only trained anesthesiologists will perform the procedure. The study will look at: Main goal: how often the tube goes in correctly on the first attempt. Other goals: overall success within 3 attempts, how well the airway is seen, how long the intubation takes, how satisfied the doctor is with the device, and possible side effects such as sore throat, dental injury, or oral injury. Participation will not change the usual care people receive during anesthesia. Both devices are already approved for clinical use. Risks are the same as with any standard intubation, and participants will be checked after surgery for any problems. By comparing these two devices, researchers hope to learn if Laringocel® can provide safe and effective intubation at lower cost, improving access to advanced airway tools.
