摘要
目的 评价利多卡因局部麻醉在超声引导经直肠前列腺穿刺活检术中的有效性和安全性。 方法 150例PSA升高和 (或 )DRE异常和 (或 )TRUS异常患者接受超声引导经直肠前列腺10针穿刺活检术 ,随机分成 3组 ,每组 50例 ,第 1组在尖部及两侧的前列腺精囊连接部注射 2 %利多卡因 ,每点 3ml,第 2组注射生理盐水 ,第 3组为对照组 ;穿刺结束后即刻对患者进行VAS疼痛评分。 结果 利多卡因组疼痛评分 0～ 7.5分 ,平均 2 .0分 ;生理盐水组 0～ 9.1分 ,平均 4.0分 ;对照组 0～ 7.4分 ,平均 3 .7分。经方差分析检验 ,利多卡因组与生理盐水组及对照组差异有显著性意义 (P <0 .0 5) ,后两组间差异无显著性意义 (P >0 .0 5) ,利多卡因组疼痛程度低于生理盐水组与对照组。 150例患者观察 6～ 10d ,无并发症发生。 结论 利多卡因局部麻醉操作简便 ,安全有效 ,能显著降低患者术中的疼痛感觉 。
Objective To assess the safety and effica cy of local lidocaine anesthesia for pain control during transrectal ultrasound-g uided 10-core biopsy of the prostate. Methods Transrect al ultrasound-guided prostate biopsy was performed for 150 consecutive men beca use of an abnormal digital rectal examination and(or) abnormal transrectal ult rasound scan and(or) elevated prostate specific antigen.100 paients were rando mly assigned to receive an injection of 2% lidocaine (group 1,50 cases)or norm al saline(group 2,50 cases)into the lateral and apical periprostatic region,3 ml in each point,the other 50 patients(group 3) served as controls.Immediate ly after biopsy the pain score was recorded independently by a nurse using 10-p oint visual analog scale(VAS). Results The pain score range was 0 to 7.5 in the group 1,0 to 9.1 in the group 2 and 0 to 7.4 in the co ntrol group,the mean pain scores being 2.0 in the group 1,4.0 in the group 2 a nd 3.7 in the control group.The diffrence between group 1 and group 2、3 was sig nificant( P < 0.05 ).No adverse events were noted. Conclusions Transrectal ultrasound-guided lateral and apical periprostatic ane sthesia significantly diminishes the pain caused by transrectal prostate biopsy ,and the procedure is simple and safe.It was recommended that the mentioned pro cedure could be adopted for all patients undergoing transrectal prostate biopsy.
