Background:
The use of videolaryngoscopes is recommended as a part of routine practice in anaesthesia for morbidly obese patients. The aim of this study was to evaluate C-Mac in a group of morbidly obese patients to see if it improves intubation conditions.
Methods:
86 morbidly obese (BMI > 40 kg m⁻²) patients scheduled for bariatric surgery were included in the study. In every studied case, C-Mac was used with a Mackintosh shaped blade. For the first attempt, the anaesthetists performing the intubation were asked to use a videolaryngoscope as a standard laryngoscope (they were blinded to the monitor display) and evaluate the glottic view in direct laryngoscopy. Then they were asked to look at the monitor of the videolaryngoscope and intubate the patient. The laryngoscopy conditions were evaluated using the Cormack-Lahane (CL) scale. The time from picking up the laryngoscope to inserting the endotracheal tube was recorded.
Results:
The evaluation of CL grade in direct laryngoscopy was: 44 patients - grade 1; 23 patients - grade 2; 13 patients - grade 3; six patients - grade 4. In all cases of CL grade > 1 in direct laryngoscopy, the use of C-Mac improved CL grade to 1. Mean time of intubation was 17.2 ± 2.5 sec.
Conclusion:
The C-Mac improves laryngeal view in morbidly obese patients, and allows for fast endotracheal intubation.
Insights
The C-Mac videolaryngoscope improves visualization of the larynx in morbidly obese patients undergoing bariatric surgery. This device facilitates faster endotracheal intubation, enhancing patient safety during anesthesia.
Area of Science:
- Anesthesiology
- Medical Devices
- Obesity Medicine
Background:
- Videolaryngoscopes are recommended for anesthesia in morbidly obese patients.
- Evaluating the C-Mac videolaryngoscope's efficacy in this patient group is crucial.
Purpose of the Study:
- To assess if the C-Mac videolaryngoscope improves intubation conditions in morbidly obese patients.
- To compare direct laryngoscopy with C-Mac videolaryngoscopy.
Main Methods:
- 86 morbidly obese patients (BMI > 40 kg/m²) undergoing bariatric surgery were enrolled.
- C-Mac videolaryngoscope with a Macintosh blade was used.
- Anesthetists compared direct laryngoscopy (blinded to monitor) with C-Mac visualization, evaluating Cormack-Lehane (CL) grade and intubation time.
Main Results:
- Direct laryngoscopy yielded CL grades: 1 (44 patients), 2 (23), 3 (13), 4 (6).
- C-Mac use improved CL grade to 1 in all cases with CL grade > 1.
- Mean intubation time was 17.2 ± 2.5 seconds.
Conclusions:
- The C-Mac videolaryngoscope significantly improves laryngeal view in morbidly obese patients.
- It enables rapid and effective endotracheal intubation in this challenging population.

Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due...
