ABSTRACT

Objective To evaluate the effect of aminophylline on the efficacy of extubation under ultra-fast track anesthesia ( UFTA) in pediatric patients with congenital heart disease ( CHD) undergoing surgical correction of anomaly. Methods Ninety American Society of Anesthesiologists physical status Ⅰor Ⅱ pediatric patients, aged<6 yr, undergoing surgical correction of anomaly, were randomized into 3 groups ( n=30 each) using a random number table method: group Ⅰ, group Ⅱ and group Ⅲ. After the end of surgery, normal saline was given in groupⅠ, 1 mg∕kg aminophylline was given in groupⅡ, and 2 mg∕kg aminophylline was given in groupⅢ. The condition of extubation in the operating room and respirato-ry rate at extubation were recorded. Mean arterial pressure, heart rate and bispectral index value were re-corded at the end of surgery, and at 9 and 15 min after administration. Results Compared with groupⅠ, the rate of successful extubation in the operating room, BIS value at 9 min after administration and respira-tory rate at extubation were significantly increased inⅡand Ⅲ groups ( P<0. 05) . There was no significant difference in the parameters mentioned above between group Ⅱand group Ⅲ ( P>0. 05 ) . Conclusion Aminophylline can increase the efficacy of extubation under UFTA in pediatric patients with CHD undergoing surgical correction of anomaly, and 1 mg is the recommended dose.
