ABSTRACT

Bronchofibroscopy is widely used in the context of orotracheal intubation in difficult airways. The cost of the equipment and the larger learning curve required compared to direct laryngoscopy increases its difficulty of use. Bronchofibroscopy may be less traumatic than direct laryngoscopy, triggering a lower hemodynamic response. Thus, we evaluated the behavior of heart rate and mean blood pressure in the process of orotracheal intubation by direct laryngoscopy and bronchofibroscopy in any airway scenario. Two groups of patients underwent orotracheal intubation by direct laryngoscopy (N = 32), group L, and bronchofibroscopy (N = 31), group B. These patients receiving elective surgeries at Gaffée and Guinle University Hospital (Hospital Universitário Gaffrée e Guinle – HUGG) were aged 18 years or older and did not have a full stomach. The predictors of difficult airways were evaluated during the pre-anesthetic evaluation, and the procedures were performed by the same anesthesiologist for both groups. All cases were performed under general anesthesia. Group L presented a rise in heart rate and mean blood pressure at the end of the procedure (p < 0.05), alterations not observed in group B. The duration of the procedure was higher in group B (p < 0.05). There was no intubation failure in any of the study patients. The absence of elevation in the parameters of heart rate and mean blood pressure in patients submitted to bronchofibroscopy orotracheal intubation compared to those intubated by direct laryngoscopy may be related to a lower nociceptive response and might lead to a broader indication of bronchofibroscopy in select clinical settings, regardless of the degree of airway difficulty.
