巴西圣保罗联邦圣保罗大学眼科的Pereira F近日在Cornea发表了他们的一项工作,他们比较了局部使用不同浓度的利多卡因凝胶与标准结膜下麻醉的疗效。

这是一项前瞻性随机对照试点研究,有3个不同的组别。SC组是在手术过程中,根据需要接受结膜下利多卡因和丙胺卡因滴剂治疗。L2组接受2%利多卡因凝胶治疗,L5组接受5%利多卡因凝胶治疗。两个利多卡因凝胶组在治疗过程中可根据需要接受另一种凝胶剂量治疗。主要的评价指标是手术期间和手术后的疼痛。评价的时间点有:1-第一切口,2-翼状胬肉切除手术,3-结膜缝合手术,4-术后初期,5-术后评估(在术后没有外科医生的情况下,由经过培训的护士进行评估)。在手术的预定阶段,使用10点线性类比量表进行评估。

他们总共招募了45名接受初期翼状胬肉切除手术的病人。在不同给药组间,平均疼痛具有统计学意义的显着差异。SC、L2和L5组平均疼痛的数据分别为2.2、0.4与0.0。麻醉药滴的重复使用次数在各组之间没有显着性差异。他们发现,麻药的重新应用与给药时的疼痛和手术持续时间之间存在显着相关性。

因此,他们证实了,在翼状胬肉切除手术中,2%和5%浓度的利多卡因凝胶与结膜下注射利多卡因在减少术中和术后疼痛方面具有同样的疗效,同时,利多卡因凝胶在给药初期可以显着减少疼痛。
