摘要
作者在局麻药中添加0.1％麻黄素行硬膜外阻滞162例,对其麻醉性能和血压作了观察.结果表明:硬膜外腔应用麻黄素不影响硬膜外阻滞性能;阻滞后各时期患者的血压、心率与麻醉前比较,无明显变化(P>0.05);阻滞后低血压的发生率7.4％;硬膜外腔麻黄素1次用量13±2 mg显著小于文献报告的安全剂量(1次不大于30mg);全组病例无麻醉并发症.作者认为:本法能有效地预防硬膜外阻滞后的血压下降.
Local anaesthetic with 0.1% cphedrine was used for cpidural anesthesia in 162 cases. The anesthetic property and blood pressure were observed Results show that cpidural administration of cphedrine doesn't affect the cpidural blocking property; the blood pressure and heart rate have no significant changes at different stages after epidural anesthesia over those before anesthesia (P>0.05). The occuring rate of hypotension is only 7.4%. A bolus dose administered into cpidural spspe is 13 ± 2 mg which is much less than maximum limit of safe bolus dose that ia suggested to be 30 mg in literature. No complications arc noted in all cases. It is concluded that local anaesthetic with 0.1% ephedrine used for epidural anesthesia can effectively prevent hypotension caused by cpidural anesthesia.
