ABSTRACT
Objective: To determine the predictive index of difficult intubation in pediatric patients through the use of the classifications of Mallampati and Wilson corroborated by Cormack Lehane.
Material and methods: This was a descriptive, prospective, transversal, and double-blind study. During the pre-anesthetic observation, it was evaluated the airways, applying Mallampati and Wilson in children from 5 to 10 years old subjected to surgery under general anesthesia. The children were randomly assigned a number 1 or 2; taking only the numbers 1. After the anesthetic induction, it was performed a laryngoscopy and visualized the laryngeal opening, using Cormack and Lehane.
Results: Three hundred and sixty children were studied. Mallampati worked on 342 patients with grade I or II and 18 patients with grade III or IV. Wilson worked on 259 patients presenting scores of 0 or 1 and in 101 patients elder than 2 years old. From 360 laryngoscopies, 18 had Cormack Lehane III or IV. Sensibility, 15%; specificity, 72.05%, proportion of false positive, 27.9%; and negative 15%; positive predictive value, 15.1%; and negative, 98.7%; precision, 72.2%.
Conclusion: The combination between Mallampati and Wilson improves the predictive intubation index in children, despite of high proportions of false positive and negative. The assessment of airways prevents situations that may put patients at risk and improves anesthesiologists’ life quality too.
