摘要 目的探讨氯胺酮与芬太尼硬膜外小剂量麻醉超前镇痛效果。方法选择78例ASAⅠ~Ⅱ级择期胆囊切除术的患者,随机将其分为3组,术前30min均肌内注射阿托品0.5mg,苯巴比妥钠1.0g。A组(27例,氯胺酮组)续加氯胺酮30mg;B组(25例,芬太尼组)续加芬太尼30μg;C组(26例,对照组)0.9%生理盐水0.5mL。5min后注入2%利多卡因(含肾上腺素1∶20万)8~10mL。观察3组患者超前镇痛情况及并发症,并进行镇痛评分的比较。结果 3组超前镇痛作用的比较结果显示,与C组比较,A、B两组在术后疼痛及局麻药间隔时间上较其长(P<0.05或P<0.01),在局麻药用量上较其少(P<0.05),且A组较B组在术后止痛时间上要长(P<0.05);在术后镇痛评分的比较上,与B、C组比较,A组在1~3分(轻度疼痛)所占比例较其大(P<0.05),差异有显著性意义。术后并发症3组无明显差异。结论氯胺酮与芬太尼硬膜外小剂量超前镇痛均能明显抑制术中牵拉痛,提供良好的术后镇痛效果,减少阿片类药物的用量,且氯胺酮比芬太尼的效果更明显。
