痔切除术后复方利多卡因与左旋布比卡因加美蓝镇痛效果比较

Comparison of the Analgesic Effects of Lidocaine vs Bupivacaine ＆ Methylene Blue after Hemorrhoidal Resection

为观察比较痔切除术后复方利多卡因与左旋布比卡因加美蓝的镇痛效果，将骶管麻醉手术后的245例痔患者分成3组，A组给予复方利多卡因创面注射；B组给予左旋布比卡因加美蓝创面注射；C组不加任何药物。观察比较术后6个时点的疼痛时间及止痛效果。结果表明，复方利多卡因在痔切除术后能获得满意的镇痛效果，且明显减少术后尿潴留的发生率。

Two hundreds and forty five patients who underwent sacral anesthesia of different analgesics after hemorrhoidal resection were divided into 3 groups in an attempt to evaluate the analgesic effect. Lidocaine compound was injected into the surgical wound in group A, while bupivacaine and methylene blue were injected into the surgical wound in group B,and no analgesic was given in group C. The analgesic time and effect were then measured at 6 time points after operation. Results shows that lidocaine is more satisfactory in analgesic effect and in reducing occurrence rate of postoperative urinary retention.
