异丙酚清醒镇静术用于阻生齿拔除的临床观察

目的：观察异丙酚与局麻合用在阻生齿拔除术中的镇静、遗忘作用并与加用氯铵酮对比。：门诊成人阻生齿拔除４０例，随机分为异丙酚组（Ｐ组，ｎ＝２５）和异丙酚加氯胺酮组（ＰＫ组，ｎ＝１５）。首次量分别静注异丙酚０．８￣１．２ｍｇ／ｋｇ和异丙酚０．６ｍｇ／ｋｇ加氯胺酮０．２ｍｇ／ｋｇ，此后持续静注异丙酚，以维持镇静３级为度，２％利多卡因行齿槽神经阻滞。结果：术中两组均维持镇静３级。术后ＶＡＳ为０。Ｐ组和ＰＫ组

Conscious Sedation with Propofol during Extraction of the Impacted Teeth

Objective:To observe the effect of sedation and amnesia with propofol during extraction of the impacted teeth under local anesthesia.Methods:40 outpatients undergoing dental extraction were randomly assigned to receive either propofol 0 8 1 2mg/kg (group P, n= 25) or propofol 0 6 1mg/kg plus ketamine 0 2mg/kg (group PK, n= 15).Propofol was intravenously injected constantly in both groups in order to maintain sedation grade 3 2% lidocaine was used to perform nerve block.Results:Sedation grade 3 was achieved in both groups.VAS was zero postoperatively.amnesia was 80% in group P and 100% in group PK.But diziness and vomitting happened in group PK were 46 66% and 13 33% respectively.Conclusion:Consious sedation with propofol has a good effect on sedation,amnesia and psychologic protection in dental extraction.Side effect will become more when ketamine is added.
