Spinal anaesthesia was performed with a 22-gauge needle on 112 consecutive patients above fifty years of age admitted for transurethral surgery. Patients were randomly allocated to either 24 h of recumbency (group A) or ambulation as soon as the spinal had worn off (group B). Postspinal headache was found in 14% of the patients in the recumbency group and in 11% of the patients in the group of early ambulation. There were no differences between the groups regarding incidence, time of onset and duration of postspinal headache. Based on the literature and the present investigation, early ambulation is therefore recommended.
对112例年龄超过50岁因经尿道手术入院的患者，使用22号穿刺针进行脊髓麻醉。患者被随机分为两组，一组术后卧床24小时（A组），另一组脊髓麻醉作用消退后尽早活动（B组）。卧床组14%的患者和早期活动组11%的患者出现了脊髓麻醉后头痛。两组在脊髓麻醉后头痛的发生率、发作时间和持续时间方面无差异。基于文献和本研究，因此建议尽早活动。
