Forty-five patients undergoing circumcision were allocated randomly to one of three study groups to compare topical analgesia with dorsal nerve block using the midline or lateral approach. Pain scores, side effects and analgesic requirements were recorded after surgery. Patients who received topical analgesia required significantly more fentanyl and had higher pain scores at the 15-min observation period after operation. Fentanyl requirements and pain scores were similar in patients who received a dorsal nerve block using either the midline or lateral approach. The incidence of side effects after surgery was similar in all three groups.
45例行包皮环切术的患者被随机分配至三个研究组之一，以比较使用中线或外侧入路的局部镇痛与阴茎背神经阻滞。术后记录疼痛评分、副作用和镇痛需求。接受局部镇痛的患者在术后15分钟观察期需要显著更多的芬太尼，且疼痛评分更高。使用中线或外侧入路进行阴茎背神经阻滞的患者芬太尼需求量和疼痛评分相似。三组术后副作用发生率相似。
