目的:通过骶管造影的方法,评价骶管麻醉中发生血管内意外注入的发生率以及相关风险因素.方法:回顾性分析213例接受骶管造影的下腰痛或下肢放射痛患者临床资料.记录发生血管内意外注入造影剂的发生次数,并对血管内意外注入造影剂相关的风险指标进行评价.通过单因素及多因素logistic回归分析,评价骶管麻醉时发生血管内意外注入的风险因素和独立风险因素.结果:单因素回归分析结果显示,有两项因素与血管内注入相关:存在腰椎神经根性症状(P=0.02)和症状持续时间长短(P<0.01).多因素logistic回归分析显示,腰椎神经根性症状(OR=2.52, 95%CI:1.11~5.75)和症状持续时间长短(OR=1.2, 95%CI:1.01~1.31)亦为发生血管内意外注入麻醉药的独立风险因素.结论:骶管麻醉时,患者存在腰椎神经根性症状和症状持续时间长与发生血管内意外注入麻醉药有关.

Objective To evaluate the risk index for prediction of accidental intravascular injection during caudal anesthesia. Methods The clinical data of 213 patients suffering from chronic low back pain under-went sacral epidurography were analysed retrospec-tively. The incidence of accidental intravascular injec-tion during sacral epidurography was recorded. Poten-tial risk factors were investigated by univariate analysis and multivariate logistic regression. Results Univari-ate analysis showed that radicular symptoms of the lumbar spine (P=0.02) and duration of symptoms (P<0.01) were risk factors for accidental intravascular injection during sacral epidurography. Multivariate logistic regres-sion analysis also demonstrated that radicular symptoms of the lumbar spine (OR=2.52 95%CI: 1.11~5.75) and duration of symptoms (OR=1.2 95%CI: 1.01~1.31) were significant and independent risk factors. Conclusion The incidence of accidental intravascular drug injection during caudal anesthesia will be higher in patients with chronic radicular symptoms of the lumbar spine.
