两种留置针穿刺方法在放化疗病人MRI增强扫描中的应用比较

The Comparison of Two Methods of Indwelling Needle Puncture in Radiation and Chemotherapy Patients During MRI Enhancement Scanning

目的通过对两种留置针穿刺方法可操作性、病人疼痛感、高压注射时的成功率等因素的比较分析,找出一种最适合放化疗后血管差的病人的穿刺方法,在减轻病人痛苦的同时提高检查成功率。方法选取放化疗数个疗程后行增强磁共振扫描患者80例,随机分为两组,对照组使用传统留置针穿刺法;观察组使用改良后的穿刺方法;分别从操作便捷性,病人疼痛分析,高压推注成功率3个角度予以比较。结果观察组需要两位操作人员协同才能完成该操作,观察组与对照组病人的平均疼痛程度差异均具有统计学意义(t=1.66,P<0.05),MRI增强扫描高压注射成功率差异具有统计学意义(t=13,t0.05/13=2.160,P<0.05)。结论使用改良后的留置针穿刺方法,在保证操作便捷性的同时,大幅减轻病人的疼痛感,提高了放化疗后病人留置针穿刺成功率,使磁共振增强扫描能够顺利完成。

Objective To find out the better puncture method for patients after several radiation and chemotherapy with a poor vascular condition,and to reduce patient ＇s pain and improve the successful rate.Methods Selected 80 patients who have already experienced several radiation and chemotherapy before.They were randomly divided into two groups： control group using traditional needle puncture; Observation group using improved puncture. Operating convenience,patient pain extent,successful rate of high pressure push were examined. Results Observation group needed two operators together to complete the operation. The difference in average pain degree between observation group and control group was statistically significant（ t = 1. 66,P〈0. 05）.MRI enhancement scanning high- pressure injection rate also had statistically significant differences（ t =13,t0. 05 /13= 2. 160,P〈0. 05）. Conclusion Modified method not only provides operation convenience,but also significantly reduces the pain of patients and improve the success rate of puncture to guarantee MRI enhancement scanning completely.
