ABSTRACT Objective: To observe the profile of anesthesia with midazolam and propofol. Methods: 90 patients were randomly allocated into three groups. In Group A, patients were induced with midazolam 0.2mg•kg-1 and maintained with 0.15mg•kg-1•hr-1.In Group B, Propofol, 1-2mg•kg-1 was used for induction, and 2-4mg•kg-1•hr-1 for maintenance. In Group C, midazolam 0.1mg•kg-1 and propofol 0.5-1mg•kg-1 were used for induction, and midazolam 0.1mg•kg-1•hr-1 and propofol 1-2mg•kg-1•hr-1 were infused for maintainenance. Fentanyl 1.5-5μg•kg-1 and vecuronium were injected intravenously or 1%-1.5% isoflurane was inhaled as needed. SBP, DBP, HR , SpO2 and PetCO2 were monitored continuously during anesthesia. The recovery was observed. Results: In Group A, SBP decreased 10.24 mmHg after induction and increased 25.54 mmHg after intubation, patients awakened 34.44±12.35 min after operation with 6 anxiety, 11 nausea, 9 vomiting and no case dream during the first 24 hours after surgery. In Group B, SBP decreased 18.29 mmHg after induction and decreased 12.89 mmHg after intubation, and patients awakened fast (6.56± 5.74 min) with 9 anxiety, 7 dream, 13 nausea, 11 vomiting and 16 pain during the first 24 hours after the operations. In Group C, SBP decreased 15.71mmHg after induction and decreased 0.80 mmHg after intubation, and the patients opened their eyes 14.64±9.50 min after surgery with 5 anxiety, 2 dream, 8 nausea, 4 vomiting and 10 pain during the first 24 hours after operations. Conclusion: The combination of midazolam and propofol is a suitable method for general anesthesia. Key words: Midazolam; Propofol; General Anesthesia
两种或更多种静脉药物复合应用从而增进麻醉效果、降低副作用已被临床麻醉广泛采纳。咪哒唑仑(Midazolam)系苯二氮卓类药物,可产生顺行性遗忘,对循环功能影响较小,且局部刺激作用轻微,但此药代谢慢,作用时间相对较长。而非巴比妥类药物丙泊酚(Propofol)起效迅速,排泄快,作用时间短,对循环功能有抑制作用,且可引起注射部位疼痛及过敏反应。为探讨此二药配伍用于麻醉诱导及维持,是否可相互取长补短,获得较理想的效果,特进行本研究。 |
