Effectiveness of predictive factors of canine intubation

Efectividad de factores predictivos de intubación en caninos

Objetive. To determine predictors of effectiveness of airway intubation and its prognostic value, according to the morphology of the skull in dogs. Materials and methods. We performed a descriptive, observational study in two veterinary clinics, in Medellin city, Colombia. 74 dogs were evaluated randomly. All underwent Mallampati, Patil-Aldreti, Cormack-Lehane scale and distance sternum chin separated by skull morphology. Tukey test p≤0.05 were performed in skull morphology and predictive scales; in addition to principal component analysis and predictive scale race. Results. significant statistics and Mallampati between brachycephalic, dolichocephalic and mesocephalic (p=0.00), brachycephalic had difficult intubation, Cormack-Lehane differences were presented also similar between brachycephalic and the other two groups. Exhibited brachycephalic difficult intubation. Patil-Aldreti revealed brachycephalic demonstrate statistical difference from the others, with moderate difficulty. The sternum chin distance, showed no divergence for any of the three groups. Assessment predictor of intubation found that 13.51 % of dogs have difficult intubation, 37.83 % with moderate difficulty and 47.29 % showed slight difficulty for intubation. The average intubation attempts was 1.83 attempts and the average time was 123.43 sec. The main components determined that breeds Bulldog, is predicted by Mallampati and Patil-Aldreti while Pinscher is predicted by Cormack Lehane. Mixed races, is not influenced by a predictor. Conclusions. Brachycephalic type canines are those with greater difficulty of intubation and Mallampati is the main predictor factor.
