Audiograms were performed preoperatively and 2 days postoperatively in 28 patients given spinal anesthesia for transurethral resection of the prostate. In 14 patients 22-gauge and in 14 patients 26-gauge spinal needles were used. Hearing loss of 10 dB or more at any frequency was observed in 13 of 14 patients in the 22-gauge group and in 4 of 14 patients in the 26-gauge group. There was a statistically significant reduction in hearing level in the low-frequency range in patients in whom the 22-gauge needle was used. Hearing loss was unilateral at five frequencies and bilateral at one frequency. No cases of postspinal headache occurred. Audiometry may be a more sensitive indication of cerebrospinal fluid leak than postspinal headache.
对28例接受脊髓麻醉以行经尿道前列腺切除术的患者在术前及术后2天进行了听力图检查。14例患者使用22号脊髓穿刺针，14例患者使用26号脊髓穿刺针。22号组14例患者中有13例在任一频率出现10 dB或更高的听力损失，26号组14例患者中有4例出现这种情况。使用22号穿刺针的患者在低频范围内听力水平有统计学意义的下降。听力损失在五个频率为单侧，在一个频率为双侧。未发生脊髓穿刺后头痛病例。听力测定可能比脊髓穿刺后头痛更能敏感地提示脑脊液漏。
