摘要
目的比较不同剂量右美托咪定复合罗哌卡因行臂丛阻滞缓解止血带疼痛的效果。方法选取我院收治的58例上肢手术患者作为研究对象,随机分组,各29例。两组患者均予以0.375%罗哌卡因,常规组患者于此基础上应用50μg右美托咪定治疗,研究组于此基础上应用100μg右美托咪定。比较两组患者治疗后臂丛神经阻滞效果及止血带疼痛程度。结果常规组患者感觉、运动神经阻滞持续时间分别为(385.6±32.9)min、(452.3±45.2)min,均少于研究组(422.1±40.3)min、(493.4±51.0)min,两组差异显著(P<0.05);常规组患者治疗后疼痛评分(3.6±1.0)分,高于研究组(2.6±0.5)分,两组差异显著(P<0.05)。结论 100μg右美托咪定复合罗哌卡因行臂丛神经阻滞,可有效延长患者感觉、运动神经阻滞持续时间,且可有效降低其止血带疼痛程度,临床治疗中值得推广应用。
Objective To evaluate effect of the different doses of dexmedetomidine combined with ropivacaine for brachial plexus block and the effects of alleviate tourniquet pain. Methods 58 cases of upper limb surgery in our hospital were selected as the research objects, they were randomly divided into groups, and there were 29 cases in each group. Patients of two groups were treated with 0.375%, the patients of the conventional group on the basis of above were applied 50 μg dexmedetomidine treatment, the study group on the basis of above was applied 100 μg of dexmedetomidine. The effect of brachial plexus block effect and tourniquet pain of two groups was compared. Results In conventional group,the block duration of Sensory and motor nerve were（385.6±32.9） min,（452.3±45.2） min, which were less than the study group（422.1±40.3） min,（493.4±51.0） min, the difference was significant（P〈0.05）;The pain scores of patients in the conventional group after treatment was（3.6±1.0）, which was higher than the study group（2.6±0.5）, the two groups had significant difference（P〈0.05）. Conclusion 100 μg of dexmedetomidine combined with ropivacaine for brachial plexus block, can effectively prolong the duration of patients with sensory and motor nerve tissue and can effectively reduce the degree of tourniquet pain, clinical treatment worth popularization and application.
