Resumen
LOPEZ-MAYA, Lorena; LINA-MANJARREZ, Francisco; LINA-LOPEZ, Lorena Monserrat y LOPEZ-GAMEZ, Laura. Use of devices (McCoy sheet vs. Airtraq® videolaryngoscope) in obese patient with predictors of difficult airway in general surgery. Rev. mex. anestesiol. [online]. 2021, vol.44, n.1, pp.22-33. Epub 11-Oct-2021. ISSN 0484-7903. https://doi.org/10.35366/97774.
A controlled, prospective, comparative, randomized, simple blind clinical trial was conducted.
Objective:
Determine the correlation and predictive value of the airway assessment and difficult intubation scales, obesity, McCoy sheet and Airtraq® type videolaryngoscope.
Material and methods:
152 patients scheduled for surgery, with a history of obesity and risk factors for difficult ventilation and intubation under general anesthesia. Two groups were formed: group, intubation with McCoy sheet and group 2, Airtraq® videolaryngoscope.
Results:
In the contrast statistics of difficult ventilation, statistical significance was obtained with p < 0.05 for all factors except snoring. In predictors of difficult intubation, the Mallampati and Cormack-Lehane classification obtained p < 0.05, with sensitivity of 63 and 68% respectively, with a high negative predictive value for all factors. The average of attempts was 1 and duration 55-59 seconds, in both groups. There were not differences with the use of McCoy sheet and Airtraq®.
Conclusions:
Orotracheal intubation was successful in 97% of cases, thanks to the use of difficult intubation predictors and devices for managing it.
