药物成份或治疗方案详述: |
进入手术室前于病房建立静脉通道。进入手术室后监测患者的心电图、无创血压、心率、血氧饱和度和脑氧饱和度。静脉注射阿托品0.02mg/kg,同时吸入七氟醚联合100%氧气面罩通气、静脉注射顺式磺酸阿曲库铵0.15mg/kg诱导麻醉,气管插管后行机械通气。在超声引导下于骶管内注射0.2%的罗哌卡因1ml/kg,给药15min后开始手术。 对照组和DEX组均使用七氟烷维持麻醉,呼气末浓度0.6-0.8MAC。DEX组从诱导阶段给予右美托咪定0.2ug/kg/h,对照组给予对应体积生理盐水。 术中监测动脉血气分析和体温,维持水、电解质和酸碱平衡,维持动脉血二氧化碳分压和体温在正常范围内。手术完成后,停DEX和七氟醚吸入,患者带管送至麻醉恢复室。记录生命体征, |

Description for medicine or protocol of treatment in detail: |
Before entering the operating room, an intravenous access was established in the ward. After entering the operating room, the patients' electrocardiogram (ECG), non-invasive blood pressure, heart rate, pulse oxygen saturation and cerebral oxygen saturation were monitored. Anesthesia was induced with intravenous atropine at 0.02 mg/kg, combined with sevoflurane inhalation via face mask with 100% oxygen, and intravenous cisatracurium besilate at 0.15 mg/kg. Mechanical ventilation was performed after tracheal intubation. Under ultrasound guidance, 0.2% ropivacaine at 1 mL/kg was injected into the sacral canal, and surgery was started 15 minutes after drug administration. Anesthesia was maintained with sevoflurane in both the control group and the DEX group, with an end-tidal concentration of 0.6–0.8 MAC. The DEX group received dexmedetomidine at 0.2 μg/kg/h from the induction phase, while the control group received an equivalent volume of normal saline. Intraoperative arterial blood gas analysis and body temperature were monitored to maintain water, electrolyte and acid-base balance, and to keep arterial partial pressure of carbon dioxide and body temperature within normal ranges. After surgery was completed, DEX infusion and sevoflurane inhalation were discontinued, and the patients were transferred to the post-anesthesia care unit (PACU) with the endotracheal tube retained. |
