Abstract

BACKGROUND: Management of the airway in patients undergoing surgery is increasingly difficult. The airway management in the operating room in terms of the initial action of anesthesia is very important. Video-laryngoscopy has been shown to provide a better view of the larynx’s structure compared to direct visualization.

AIM: We describe our experience using a custom made and inexpensive tool for a video-laryngoscopy.

METHODS: This is an experimental research with single randomized clinical trial conducted at the Anesthesiology Department of Sanglah General Hospital Denpasar. There were 270 patients divides into three group with conventional, O-Mac® and Mc-GRATH™ BF laryngoscope, aged 18–65 years old, with Mallampati grade 1–2, randomly selected, and signed informed consent.

RESULTS: Intubation time fastest with O-Mac® median 26 (15–36) s, p = 0.000. Laryngoscopy time fastest with O-Mac® median 5.5 (2–13 s), p = 0.000. O-Mac® does not use many tools, p = 0.000. All three did not produce tissue damage with results p = 0.007. Hemodynamic changes p = 0.000.

CONCLUSION: The O-Mac® is superior in terms of laryngoscope time and intubation time compared to the Mc-GRATH™ BF blade and has the same level of safety as the patented Mc-GRATH ™ video laryngoscope, and better than conventional laryngoscopes.
