Methods:Sixty patients aged 22d ~10y (ASA Ⅱ-Ⅲ) were randomly assigned into three groups with 20 cases each. Patients in three groups were given fentanyl 10μg/kg within 10 seconds, 20 seconds or 30 seconds intravenously. The occurrence of cough, vital sign profiles and side effects were recorded after fentanyl bolus by an anesthesiologist blined to study design. Results:Ninety percent of patients in the 10s group had cough, whereas the frequency of cough was significantly decreased in the 20s group (55%) and 30s group(45%, P<0.05). However, the differences of SBP, DBP, HR among three groups were not significant. Conclusion:Prolonging injection time was effective in preventing fentanyl induced cough in children with congenital heart disease.
