目的:探讨右美托咪定复合罗哌卡因在小儿腋路臂丛阻滞中的应用效果。方法:我院于2015年6月至2017年6月随机选取了72例进行上肢手术的患儿作为研究对象,将其分为对照组和观察组,每组36例。为了更好的帮助患儿进行手术,其中对对照组采用罗哌卡因行腋路臂丛神经阻滞,而对观察组则采用罗哌卡因复合右美托咪定。等到手术结束之后,观察两组患儿的臂丛神经阻滞起效和镇痛持续时间,并对两组患者的FLACC方面随着时间发展的变化和不良反应进行观察和对比。结果:两组患者手术结束之后,观察组患者的FLACC评分在4h、6h、8h之后,明显高于对照组,并且观察组的臂丛起效时间(8.56±3.89)分钟明显低于对照组(13.42±2.98)分钟,而阵痛持续时间(70.56±43.12)分钟,也明显高于对照组(58.44±23.78)分钟,两组差异显著,具有统计学意义(P<0.05)。结论:通过右美托咪定复合罗哌卡因在小儿腋路臂丛阻滞中的应用,使得罗哌卡因的神经阻滞时间有所延长,同时对于手术患儿的手术有着良好的镇痛效果,有利于帮助患儿促进身体方面的康复,有着一定的临床应用价值。
Objective: To investigate the effect of dexmedetomidine plus ropivacaine on axillary brachial plexus block in children. Methods: From June 2015 to June 2017, 72 children with upper extremity surgery were randomly selected from our hospital for study. They were divided into control group and observation group with 36 cases in each group. In order to better help children with surgery, ropivacaine axillary brachial plexus block was used in the control group and ropivacaine combined dexmedetomidine was used in the observation group. After the operation was over, the onset of brachial plexus block and the duration of analgesia were observed in both groups. The changes of FLACC and the adverse reactions in both groups were observed and compared. Results: After surgery, the FLACC score of the observation group was significantly higher than that of the control group after 4h, 6h, 8h, and the brachial plexus onset time (8.56 ± 3.89) in the observation group was significantly lower than that of the control group 13.42 ± 2.98) minutes, while the pain duration (70.56 ± 43.12) minutes was also significantly higher than that of the control group (58.44 ± 23.78) minutes. There was significant difference between the two groups (P <0.05). CONCLUSIONS: The use of dexmedetomidine plus ropivacaine in pediatric axillary brachial plexus prolongs the duration of ropivacaine blockade and has a good town for surgeries Pain effect, help to promote physical rehabilitation in children, has a certain clinical value.
