摘要:
目的 通过比较颅外非半月节射频热凝治疗三叉神经痛时局部麻醉与全凭静脉麻醉镇静镇痛效果, 以遴选最佳舒适化医疗流程与监护管理措施。 方法 将2018年1—10月从本课题组收治并确诊的150例三叉神经痛患者用随机数字表法随机分成甲、乙、丙3组, 每组各50例: 甲组除穿刺点局部麻醉外不再作任何麻醉干预; 乙、丙2组先静脉注射右美托咪啶0.3 μg/kg, 待穿刺成功电生理确认无误后, 乙组经射频针注入2%利多卡因0.5 mL, 5 min后开始射频热治疗; 丙组静脉注入丙泊酚1.0~1.5 mg/kg, 待患者入睡后再行射频治疗。根据术中血压、心率、血氧饱和度监测值变化给予乌拉地尔、麻黄碱、阿托品等相应血管活性药物以维持循环稳定。记录患者血压、心率及氧饱和度值及术中各药物用量, 以及术中并发症、术后近期疗效和患者满意度。 结果 甲组治疗期间血压、心率值均显著高于基础值, 且在穿刺操作(T1)和射频第60 s(T2)时点, 甲组血压、心率值与乙、丙2组升高, 差异有统计学意义(均P < 0.05)。甲组治疗期间有68%的患者需用血管活性药控制血压, 舒适化满意度丙组显著高于甲、乙2组(均P < 0.05)。 结论 颅外非半月节射频热凝治疗三叉神经痛时穿刺前给予右美托咪啶, 射频前静注适量丙泊酚可提高射频治疗的舒适度和满意度, 且不影响近期疗效判断, 但需吸氧、监护, 必要时使用血管活性药物维持循环稳定以策安全。 Abstract:Objective By comparing the effects of local anesthesia and total intravenous anesthesia in the treatment of trigeminal neuralgia by extracranial non-Gasserian ganglia radiofrequency thermocoagulation, the optimal comfortable medical process and monitoring management measures were selected. Methods A total of 150 patients with trigeminal neuralgia scheduled for radiofrequency thermocoagulation of extracranial non-Gasserian ganglia were randomly divided into three groups with random number table method: group A received no anesthetic intervention except local anesthesia at puncture point; The others received intravenous injection of dexmedetomidine (0.3 μg/kg), after electrophysiological tests were correct, group B received injection of 2% lidocaine 0.5 mL through radiofrequency needle; In group C, propofol was injected intravenously 1.0-1.5 mg/kg. Then radiofrequency therapy was performed after patients fell asleep. The corresponding vasoactive drugs such as urapidil, ephedrine and atropine were given to maintain circulation stability according to the changes of blood pressure, heart rate and oxygen saturation during operation. The blood pressure, heart rate, oxygen saturation, intraoperative dosage of drugs, intraoperative complications, short-term efficacy and patient satisfaction were recorded. Results Blood pressure and heart rate in group A were significantly higher than the baseline values during treatment, and at T1 (Puncture operation) and T2 (radiofrequency thermocoagulation 60 s), blood pressure and heart rate in group A were significantly higher than those in group B and C (all P < 0.05), respectively. 68% of patients in group A needed vasoactive drugs to control blood pressure during treatment, and comfort satisfaction in group C was significantly higher than those in group A and B (all P < 0.05). Conclusion When patients with trigeminal neuralgia are treated with extracranial radiofrequency thermocoagulation, dexmedetomidine injection before puncture and propofol injection before radiofrequency can greatly improve the comfort and satisfaction of radiofrequency therapy, without affecting the short-term efficacy judgement, but they need oxygen inhalation and monitoring, and use vasoactive drugs to maintain circulation stability when necessary to ensure safety. -
