ABSTRACT
BACKGROUND:
Perioperative respiratory adverse events (PRAEs) are a major cause of morbidity and mortality associated with pediatric anesthesia. Topical lidocaine administration reduces risk of PRAE in children undergoing elective endotracheal intubation. However, definitive evidence of its efficacy remains elusive, due, in part, to the wide variability in the methodology for spraying topical lidocaine. In this randomized controlled double-blind clinical trial, we sought to evaluate the effect of site-directed topical airway lidocaine, sprayed directly onto supraglottic, glottis, and subglottic areas, on the incidence of PRAE.METHODS:
The study population consisted of 322 children (age range, 6 mo-12 y), who were scheduled for an elective surgical procedure under general anesthesia with endotracheal intubation. Patients were randomly assigned to receive topical spray of lidocaine (group L) or saline (group S) over the supraglottic, glottis and subglottic areas under direct vision before tracheal intubation. Incidence of PRAE and time to extubation was recorded.RESULTS:
There were no statistically significant intergroup differences with regard to baseline demographics, patient characteristics, and surgical parameters. Group L was associated with a significantly lower incidence of PRAE as compared with group S (12.80% versus 38.13%, respectively; P < 0.001). Similarly, the incidence of laryngospasm (1.7% versus 8.1%; P = 0.01), excessive coughing (4.3% versus 13.2%; P = 0.005), and oxygen desaturation <95% (6.8% versus 16.9%; P = 0.005), respectively, was significantly lower in group L. However, time to extubation was longer in group L as compared with that in group S (18.6 ± 7.7 min versus 21.3 ± 8.9 min; P = 0.03).CONCLUSIONS:
Site-directed topical spray of lidocaine over supraglottic, glottis, and subglottic areas before tracheal intubation significantly reduced the incidence of PRAE and a prolongation of extubation time in children.Palabras clave
