盲法星状神经节阻滞的学习曲线

LEARNING CURVE OF BLINDLY BLOCKING STELLATE GANGLION

目的:总结盲法星状神经节阻滞的学习曲线。方法:回顾性收集2012年3月至2012年9月由同一术者连续完成的300例星状神经节阻滞治疗的病例资料,按治疗先后顺序分为A、B、C、D、E 5组,每组60例,从各组霍纳征出现率及并发症发生率等指标比较治疗效果。结果:A、B组的霍纳征出现率明显低于C、D、E组(P<0.05),A、B组的并发症发生率明显高于C、D、E组(P<0.05)。结论:盲法星状神经节阻滞的学习曲线约为120例。

Objective： To evaluate the learning curve to master the stellate-ganglion blocking procedure. Methods： 300 cases, who received stellate-ganglion block performed by a surgeon during March to September in 2012, were enrolled and reviewed. According to the blocking sequence, the cases were divided into five groups （referred as Group A, B, C, D and E） and consequently there were 60 cases in each group. The rate of Homer＇s syndrome and postoperative complications were used to evaluate the curative effect. Results： The incidence rates of Homer＇s syndrome in Groups A and B were less than those in Groups C, D and E （P 〈 0.05）. However, the postoperative complications appear to be an opposite trend. Conclusion： We suggest that 120 cases should be a standard in mastering the stellate-ganglion blocking procedure.
