Fifty boys presenting for day case circumcision were allocated randomly to receive either caudal analgesia or dorsal nerve block (DNB) to provide postoperative pain relief. Analgesia was assessed by a single, unbiased observer utilising a three-point scale. Subsequently, parents completed a simple questionnaire. Subjects in the DNB group micturated earlier (P less than 0.05) and stood unaided earlier (P less than 0.025) than patients in the caudal group. The incidence of vomiting was significantly lower in the DNB group (P less than 0.05). There was no significant difference in the duration of analgesia, although that produced in the DNB group tended to wane sooner. It is concluded that DNB provides satisfactory analgesia following circumcision and has specific advantages when compared with caudal analgesia.
五十名接受日间包皮环切术的男孩被随机分配，分别接受骶管阻滞或阴茎背神经阻滞（DNB）以缓解术后疼痛。由一名公正的观察者使用三点量表评估镇痛效果。随后，家长们填写了一份简单的问卷。DNB组的受试者比骶管阻滞组的患者排尿更早（P<0.05），独立站立更早（P<0.025）。DNB组呕吐发生率显著更低（P<0.05）。镇痛持续时间无显著差异，尽管DNB组产生的镇痛效果趋于更快消退。得出的结论是，DNB在包皮环切术后提供了满意的镇痛效果，与骶管阻滞相比具有特定优势。
