BackgroundEmergence from general anesthesia can be associated with coughing, agitation, and hemodynamic disturbances. Remifentanil may attenuate these responses.MethodsIn a prospective, double-blind, randomized trial, we enrolled 60 adult patients undergoing nasal surgery using remifentanil-based anesthesia. During the emergence phase, the remifentanil group had remifentanil reduced to one tenth of the maintenance rate, whereas the control group had remifentanil discontinued.ResultsTimes to awakening and tracheal extubation were similar between the two groups. During emergence, the remifentanil group (infusion rate 0.014 +/- 0.011 microg x kg(-1) x min(-1)) had a significantly lower incidence (40% vs 80%, P = 0.002) and less severe coughing compared with the control group, as well as a lower incidence of nonpurposeful movement (3.3% vs 30%, P = 0.006) and slower heart rates.ConclusionsLow-dose remifentanil during emergence did not prolong wake-up but reduced the incidence and severity of coughing from the endotracheal tube.
