摘要

在一项前瞻性研究中,对100例在脊髓麻醉下接受普通外科或泌尿外科手术的患者进行检查,以确定麻醉与术后听力损失之间是否存在关系。术前及术后第1、2、3、5天进行听力图。16例患者有听力障碍。这些患者的平均年龄与总人口的年龄相似。听力损失是典型的:只有125和2000赫兹之间的频率受到影响。自脊髓麻醉后第2天发病,无特殊治疗,3天内消失。脊髓麻醉后听力损失的典型原因是脑脊液压力下降,通过耳蜗导水管传递到淋巴管周围。淋巴内压差的变化导致基底膜振荡的变化。由于16%的患者在脊髓麻醉后可能出现听力损失,从医学法律的角度向患者解释听力缺陷的可能性似乎是合理的。

[Transient medium- and deep-tone hearing disorders following spinal anesthesia].

In a prospective study, 100 patients who underwent general surgical or urological operations under spinal anesthesia were examined to determine whether there was a relation between the anesthesia and postoperative hearing loss. Audiograms were performed preoperatively and as the 1st, 2nd, 3rd, and 5th postoperative days. It was found that 16 patients had impairment of hearing. The average ages of these patients were similar to those of the total population. The hearing loss was typical: only the frequencies between 125 and 2000 Hz were affected. It began on the 2nd day after spinal anesthesia and disappeared within 3 days without special therapy. The cause of this typical hearing loss after spinal anesthesia is a drop in cerebrospinal fluid pressure transmitted to the perilymph via the cochlear aqueduct. The change in the endoperilymphatic pressure difference results in a change in the oscillation of the basilar membrane. Because 16% of patients may suffer hearing loss after spinal anesthesia, it seems reasonable from a medicolegal point of view to explain the possibility of defective hearing to the patient.
