常温下行动脉导管未闭结扎患儿术后硬膜外自控镇痛

Automatic Control Narcosis in Epidural Block after Normothermia Patent Ducts Arteriosus Ligature

目的 :观察先天性心脏病—动脉导管未闭 (PDA)患儿在常温下行结扎术术后硬膜外自控镇痛的疗效。方法 :32例PDA手术患儿随机分为两组 ,A组采用术后硬膜外自控镇痛 ;B组采用术后肌注吗啡 0 1～ 0 .2mg kg镇痛 ,比较两组患儿镇痛、镇静及术后行控制性降压所用硝普钠的量。结果 :A组术后镇痛评分明显小于B组 (P <0 0 5 ) ,A组术后 2 4h内所用硝普钠的量明显小于B组 (P <0 0 5 )。结论 :采用术后硬膜外自控镇痛效果好 。

Objective:To investigate the effect of automatic control narcosis in epidural block after normothermia patent ducts arteriosus ligature in congenital heart disease.Method:32 Children underwent patent ducts arteriosus ligature were randomly divided into two groups:group A treated with postoperative automatic control narcosis in epidural block;group B treated with postoperative morphine(0 1～0 2mg/kg).The effect of narcosis and sedation and dosage of sodium nitroprusside in postoperative 24 hours were compared between two groups.Result:The narcotic score and dosage of sodium nitroprusside in postoperative 24 hours in group A was statistically lower than that in group B (P<0.05).Conclusion:Postoperative automatic control narcosis in epidural block is effective.It protect patients's cardiac function and psychological state.
