Abstract
The incidence of intratracheal tube-induced laryngeal irritation, including coughing, bucking and cardiovascular stimulation, on emergence from general anesthesia has been reported to occur in 38% and 96% of cases. This may cause agitation and unstable hemodynamics during anesthesia recovery, and can lead to complications, such as laryngeal edema, sore throat, increased intra-abdominal pressure and anastomotic bleeding. So it is proposed to use intratracheal dexmedetomidine to prevent agitation and decrease cough severity after extubation in pediatrics emerging from general anesthesia. Sixty patients were enrolled in this study. They were equally divided into two groups.
