Audiograms were performed pre-operatively and 2 days postoperatively in 48 patients given spinal anaesthesia for transurethral resection of the prostate. Hearing levels were examined at 1000 Hz and below. Either 22 G standard design (Quincke) needles (n = 25) or 22 G pencil-point design (Whitacre) needles (n = 23) were used. Hearing loss of 10 dB or more at two or more frequencies were observed in six of 25 patients in the Quincke group and in two of 23 patients in the Whitacre group. The mean hearing level was more reduced in the Quincke group. The shape of the tip of the spinal needle seems to be of some importance to the effects on hearing level that may occur after spinal anaesthesia.
对48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。在1000赫兹及以下频率检查听力水平。使用了22G标准设计（昆克式）针（n = 25）或22G铅笔尖设计（惠特克式）针（n = 23）。在昆克式针组的25例患者中有6例以及在惠特克式针组的23例患者中有2例在两个或更多频率出现了10分贝或更高的听力损失。昆克式针组的平均听力水平下降得更多。脊髓穿刺针尖端的形状似乎对脊髓麻醉后可能出现的听力水平影响具有一定重要性。
