Abstract:

Objective　To investigate the clinical effect of low-temperature shock analgesia combined with muscle patch on patients with contrast medium extravasation during CT examination. Methods　From July 2016 to December 2021, 60 patients with contrast medium extravasation during CT angiography (CTA) examination were selected from Guangdong Second Provincial General Hospital by the handy sampling method, and were randomly divided into a control group and an observation group, with 30 patients in each group. In the control group, there were 19 males and 11 females, aged 44-74 (61.0±9.6) years; in the observation group, there were 20 males and 10 females, aged 48-72 (60.0±7.4) years. The control group used 50% magnesium sulfate for 1 h, 4 times a day, while the observation group used a low-temperature impact therapy analgesic device, followed by muscle patch. The Visual Analogue Scale (VAS) score, treatment effective rate, significant effective rate, onset time, and cure time were compared between the two groups. Independent sample t test and χ² test were used as statistical methods. Results　The VAS scores of the observation group 24 and 48 h after surgery were lower than those of the control group [(4.13±1.36) points vs. (5.33±1.23) points, t=2.535, P<0.05; (2.93±1.03) points vs. (4.00±1.07) points, t=2.779, P<0.05]. The significant effective rate of the observation group was higher than that of the control group [86.67% (26/30) vs. 63.33% (19/30)], with a statistically significant difference (χ²=4.356, P=0.037); there was no statistically significant difference in the effective rate between the two groups (χ²=0.162, P>0.05). The onset time and cure time in the observation group were shorter than those in the control group [(5.33±1.45) h vs. (6.67±1.35) h, t=2.613, P<0.05; (20.53±4.32) h vs. (23.60±3.80) h, t=2.065, P<0.05], with statistically significant differences. Conclusion　Low-temperature shock analgesia combined with muscle patch has a good effect on pain relief and swelling subsidence in patients with contrast medium extravasation, and is effective and convenient to operate, which is conducive to improving the nursing effectiveness of contrast medium extravasation and is worth further research and promotion.

摘要：

目的　探讨CT检查期间造影剂外渗患者应用低温冲击镇痛联合肌效贴护理的临床效果。方法　采用方便取样法选取2016年7月至2021年12月在广东省第二人民医院行冠状动脉CT血管造影（CTA）检查发生造影剂外渗的患者60例，根据随机分组原则分成对照组和观察组，每组30例。对照组男19例，女11例，年龄44～74（61.0±9.6）岁；观察组男20例，女10例，年龄48～72（60.0±7.4）岁。对照组使用50%硫酸镁湿敷，观察组使用低温冲击镇痛联合肌效贴外贴。比较两组患者的视觉模拟评分法（VAS）评分、显效率、治愈率、起效时间以及治愈时间。统计学方法采用独立样本t检验、χ²检验。结果　观察组患者术后24、48 h的VAS评分均低于对照组［（4.13±1.36）分比（5.33±1.23）分，t=2.535，P<0.05；（2.93±1.03）分比（4.00±1.07）分，t=2.779，P<0.05］。观察组的显效率高于对照组［86.67%（26/30）比63.33%（19/30）］，差异有统计学意义（χ²=4.356，P=0.037）；两组治愈率比较差异无统计学意义（χ²=0.162，P>0.05）。观察组患者的起效时间［（5.33±1.45）h比（6.67±1.35）h，t=2.613，P<0.05］、治愈时间［（20.53±4.32）h比（23.60±3.80）h，t=2.065，P<0.05］均短于对照组，差异均有统计学意义。结论　使用低温冲击镇痛疗法联合肌效贴对于造影剂外渗患者的疼痛缓解、肿胀消退均有良好的作用，起效迅速，操作便捷，有利于提高造影剂外渗的护理成效，值得进一步研究以及推广使用。
