咪唑安定-氯胺酮麻醉在痔瘘手术中的应用

Application of Midazolam and Katamine in the Anesthesia for Hemorrhoidal and Fistular Surgical Operations

为实施无痛痔瘘手术，对20例痔瘘患者应用咪唑安定-氯胺酮静脉麻醉结合利多卡因局部浸润麻醉，有效地消除了患者术中的疼痛与恐惧，收到理想的效果。镇痛镇静效果达到优级者17例（85％），良级者3例（15％），优良率100%。对咪唑安定-氯胺酮的用药剂量及方法尚需调整，以减轻术后并发症。

Twenty patients who underwent hemorrhoidal and fistular surgical operations received midazolam-ketamine anesthesia intravenously plus local infiltration of lidocaine. The anesthetic effect was satisfactory with the excellent rate being 85%（17/20） and the good rate being 15%（3/20）. It is suggested that the dosage of midazolam and ketamine and their use method should be regulated in the further studies so as to decrease the postoperative complications.
