BACKGROUND AND OBJECTIVES
A prospective, randomized study was performed to investigate the influence of the level of injection on sensory anesthesia when bupivacaine 0.5% adjusted to 37.0 C was used.
METHODS
Three milliliters of plain bupivacaine 0.5% were injected at either the L2-3 interspace or the L4-5 interspace. There were 10 patients in each group. The patients were kept sitting for 2 minutes after injection.
RESULTS
No significant difference in maximal level of sensory anesthesia was found (p = 0.123).
CONCLUSION
These preliminary results indicate that if a higher level of injection is more suitable for anatomic reasons, it can safely be used without the risk of a much higher level of sensory blockade.
背景与目的
进行了一项前瞻性随机研究，以调查使用经温度调节至37.0℃的0.5%布比卡因时，注射部位对感觉麻醉水平的影响。
方法
在L2 - 3椎间隙或L4 - 5椎间隙注射3毫升单纯0.5%布比卡因。每组有10例患者。注射后患者保持坐姿2分钟。
结果
未发现感觉麻醉的最高水平有显著差异（p = 0.123）。
结论
这些初步结果表明，如果出于解剖学原因较高的注射部位更合适，那么可以安全使用，而不会有产生更高水平感觉阻滞的风险。
