【摘要】 目的对比观察丙泊酚(P)与氯胺酮(K)、芬太尼(F)不同配伍用于小儿静脉麻醉的效果及其对患儿呼吸、循环的影响。方法90例手术患儿随机分为三组(每组30例),Ⅰ组:P+K+F;Ⅱ组:P+K;Ⅲ组:P+F。均用微量泵持续静脉注入麻醉药,观察各组患儿麻醉药物用量、术毕苏醒时间、镇静和镇痛的效果及麻醉期间呼吸、血流动力学变化。结果Ⅰ组与Ⅱ、Ⅲ组相比用药量明显减少,镇静和镇痛完善,对呼吸、循环的变化小,术毕苏醒时间较短(P<0.05)。结论丙泊酚复合氯胺酮、芬太尼全凭静脉麻醉用药少,镇静和镇痛完善,对小儿呼吸循环影响轻微且术毕苏醒快,优于丙泊酚复合氯胺酮或芬太尼。更多还原

【Abstract】 Objective To observe the effect of intravenous anesthesia (IVA) with propofol (P),ketamine (K) and fentanyl (F) in different ways in children. Methods 90 pediatric patients were divided into three groups ( n =30) randomly according to the drug used for IVA. Ⅰgroup used compounds of P, F and K; Ⅱgroup used compounds of P and F; Ⅲ group used compounds of P and K. All the drugs were injected intravenously with micro-pump. Total dosage of anaesthetics, awaken time after operation and variation of circulation and breath were observed and sedative and analgesic effect during operation were evaluated. Results Compared with Ⅱ or Ⅲ group, Ⅰgroup showed less dosage, shorter awaken time and smaller degree of change in circulation and breath with complete sedation and analgesia ( P <0.05). Conclusions Total IVA with propofol combined with ketamine and fentanyl in children has such advantage as lo dosage, little influence on circulation and breath and short awaken time, it is better than propofol combined with ketamine or fentanyl.更多还原
