硬膜外微电脑输液泵注药与常规推注和滴注给药麻醉的比较

A Comparison of Epidural Administration by a Computerized Infusion Pump with Conventional Injection Technic

４４例胃或胆囊切除术病人根据硬膜外腔给药方法随机分为泵输注组（ｎ＝１７）、持续滴注组（ｎ＝１４）和常规推注组（ｎ＝１３）。在泵输注和滴注组，首次量２％利多卡因经硬膜外导管以１ｍｌ／ｍｉｎ输入，首次量进入后以首次量／ｈ持续输入，直至术毕。推注组首次量以１ｍｌ／３ｓ经硬膜外导管推注以后每间隔ｌｈ追加首次量。麻醉起效时间和阻滞范围无明显差别。作者指出硬膜外腔泵输注给药方法简化，初步实现给药自动化，不影响硬膜外腔的扩散。

orty-four patients schedulled for cholecystectomy or gastrectomy were devided into continous pump infusiongroup (group P,n=17),continous drop infusion group (group D,n=14),and conventional injective group(group C,n=13).An initiatial dose of 2% lidocaine was infused into the epidural space via epidural catheter atrate of 1ml/min,which was followed by half-initial dose per hour till the end of operation in group P and D. Aninitial dose of 2% lidocaine was injected at rate of 1ml/3s and supplemented with half-initial dose everv hour ingroup C,There was no significant difference in analgesic level among three groups. It suggestes that epidural ad-ministration with infusion pump is simple and effective.
