由于药理和生理学的进步,硬脑膜外麻醉和腰麻技术的发展越来越快。作者仅报道其耳科学并发症,主要是眩晕、耳鸣和暂时性聋,其中蜗内型聋伴严重耳鸣最难治愈。据美国和斯堪的纳维亚统计,腰麻后出现耳鸣、眩晕、听敏度和暂时性听力下降者约占千分之四。Vandam和Dripps引用了多种理论来解释这些症状的病因。硬脑膜外麻醉的病例,通过穿刺针孔渗漏可能是原因之一。象头痛或动眼神经暂时性麻痹,一方面由于脑脊液经穿刺孔漏出而致脑脊液压力低下,另一方面可能与脑脊液和耳蜗间的流通有关。一般来讲,90%的病例可在3个月内恢复。持续性头痛可由穿刺处的血液粘附作用得到改善。眩晕经静脉注射15%氧化镁的硫酸盐或按视网膜动脉压注射蒸馏水而得到缓
Due to the progress of pharmacology and physiology, the development of epidural anesthesia and spinal anesthesia is getting faster and faster. The authors reported only their otologic complications, mainly dizziness, tinnitus and temporary deafness, of which cochlear deafness with severe tinnitus were the most difficult to cure. According to the United States and Scandinavian statistics, tinnitus, vertigo, hearing loss and temporary hearing loss after spinal anesthesia accounted for about four thousandths. Vandam and Dripps cite several theories to explain the etiology of these symptoms. Cases of epidural anesthesia, through puncture pinhole leakage may be one of the reasons. Temporary headache or oculomotor nerve paralysis, on the one hand as a result of cerebrospinal fluid leakage through the puncture caused by low cerebrospinal fluid pressure, on the other hand may be related to the circulation of cerebrospinal fluid and the cochlear. In general, 90% of cases can be recovered within 3 months. Persistent headaches can be improved by the blood clots at the puncture site. Vertigo by intravenous injection of 15% magnesium sulfate or retinal arterial pressure injection of distilled water and get slow
