Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Laringocel

Participants in this group will undergo orotracheal intubation using the Laringocel videolaryngoscope

Group Type EXPERIMENTAL

Laringocel® videolaryngoscope

Intervention Type DEVICE

Orotracheal intubation performed with a hyperangulated Laringocel® videolaryngoscope by board-certified anesthesiologists who have completed a validated learning curve (CUSUM).

Participants will undergo general anesthesia with adequate neuromuscular relaxation. The type and dose of anesthetic drugs will be determined by the attending anesthesiologist, ensuring at least an effective dose equivalent to ED95. If succinylcholine is used, intubation will be performed 45 seconds after administration; for cisatracurium, after 4 minutes; and for vecuronium or rocuronium, after 2 minutes.

C-MAC D-Blade

Participants in this group will undergo orotracheal intubation using the C-MAC D-Blade video laryngoscope (Karl Storz).

Group Type ACTIVE_COMPARATOR

C-MAC® D-Blade videolaryngoscope

Intervention Type DEVICE

Orotracheal intubation performed with a hyperangulated C-MAC® D-Blade videolaryngoscope (Karl Storz®) by board-certified anesthesiologists who have completed a validated learning curve (CUSUM).

Participants will undergo general anesthesia with adequate neuromuscular relaxation. The type and dose of anesthetic drugs will be determined by the attending anesthesiologist, ensuring at least an effective dose equivalent to ED95. If succinylcholine is used, intubation will be performed 45 seconds after administration; for cisatracurium, after 4 minutes; and for vecuronium or rocuronium, after 2 minutes.
