Two cases are presented, with accidents of peridural anesthesia, Anesthesia of the entire brain stem, paralysis of the intercostal muscles, and of the upper limbs, apnoea and miosis that developed later indicate an extension of the anesthetic effects far higher that it could have been expected considering the technical details of the procedure. On the other hand the absence of any durable coma, of extreme mydriasis, and of severe arterial hypotension, as well as the relatively rapid retrocession of the additional effects of the administration of an anesthetic exclude the possibility of total rachianesthesia, and it can be concluded that there was an accidental injection of anesthetic in the extra-arachnoid subdural space.
本文报告了两例硬膜外麻醉意外事件，全脑干麻醉、肋间肌和上肢麻痹，随后出现的呼吸暂停和瞳孔缩小表明麻醉效果的范围远远高于根据操作技术细节所预期的水平。另一方面，没有出现任何持久性昏迷、极度瞳孔散大以及严重动脉低血压，并且麻醉剂给药的额外效应相对较快消退，排除了全脊髓麻醉的可能性，可以得出结论，麻醉剂意外注入了蛛网膜下硬膜外间隙。
