The spread of solutions injected to the intercostal space was studied in 10 healthy volunteers. Up to 20 ml of a 50:50 mixture of local anaesthetic solution and a radiopaque dye was injected through a modified extradural catheter placed in an intercostal space at the posterior angle of the rib. Radiographic films demonstrated spread by an extrapleural route into adjacent intercostal spaces and this was confirmed by the occurrence of analgesia in the corresponding dermatomes. The relevance of these results to clinical practice is discussed.
在10名健康志愿者身上研究了注入肋间间隙的溶液的扩散情况。通过置于肋骨后角肋间间隙的改良硬膜外导管,注入高达20毫升局部麻醉溶液与不透射线染料按50:50比例混合的溶液。X线片显示溶液通过胸膜外途径扩散至相邻肋间间隙,相应皮节出现镇痛证实了这一点。讨论了这些结果与临床实践的相关性。
