利多卡因局麻在PICC置管术中应用的效果评价

Assessment the effect of local anaesthesia with lidocaine hydrochloride in PICC

目的:评价应用利多卡因进行局部麻醉后再进行PICC置管术的效果。方法:根据PICC治疗的适应证,选择121例肿瘤病人作为观察对象。将病人随机分为局麻组60例和非局麻组61例。局麻组在置管前局部注射利多卡因进行局部麻醉;而非局麻组在置管前不使用任何局麻药。调查两组病人对PICC置管疼痛的反应和置管成功率。结果:局麻组病人在PICC治疗中出现疼痛的程度明显轻于非局麻组(P<0.01),置管成功率高于非局麻组(P<0.05)。结论:在实施PICC之前,合理地应用利多卡因进行局部麻醉,不但可以减轻病人的紧张和疼痛程度,增加病人对治疗的依从性,而且还能提高置管的成功率。

Objectives ：To assess the effect of local anaesthesia with lidocaine hydrochloride before PICC. Methods ：According to the indications of PICC, 121 patients, who would receive PICC, were considered as targets for assessment and randomly divided into two groups： anaesthesia group （n = 60） and non -anaesthesia group （n = 61 ）. In the anaesthesia group, the patients were pre -treated with local anaesthesia by Lidocaine before PICC, while the patients in the non - anaesthesia group did not receive any pre - treatment. Then, the patients＇ response to PICC operations and PICC successful rates were recorded and made comparison between these two groups. Results ： Compared with the non - anaesthesia group, the anaesthesia group showed much less pains during PICC operation （P 〈 0.01 ）. Furthermore, the anaesthesia - group had a higher PICC successful rate than the non - anaesthesia group （ P 〈 0. 05 ）. Conclusion ： If local anaesthesia by Lidocaine Hydrochloride was reasonably applied before PICC, it would not only relief patient＇ s pains and nervousness and improve their compliance to therapy, but increase PICC successful rates as well.
