Abstract:
Objective:To evaluate the efficacy of ultrasound-guided sacral canal block for anesthesia in neonatal anoplasty.Methods:Sixty neonats with anal atresia, of American Society of Anesthesiology physical status ⅠorⅡ, were divided into 2 groups ( n=30 each) by a random number table method: traditional positioning method for sacral canal block group (group T) and ultrasound-guided sacral canal block group (group U). After successful puncture, 0.2% ropivacaine 1 ml/kg was injected in both groups.The success of puncture at first attempt, puncture time, successful sacral canal block and occurrence of adverse reactions were recorded. Results:Compared with group T, the success rate of puncture at first attempt was significantly increased, the puncture time was shortened ( P<0.05), and no significant change was found in the success rate of sacral canal block in group U ( P>0.05). Neonatal sacrococcygeal contents and the termination of the neonatal dural sac were observed under ultrasound in group U. Blood return in the puncture needle was observed in one case in group T, and no adverse reactions were found in group U. Conclusion:Ultrasound-guided sacral canal block provides better efficacy than the traditional sacral canal block when used for anesthesia in neonatal anoplasty.
