Pain management is an important part of care provided by nurses.
The present study aimed to investigate the effect of an innovative method named the skin traction, pressure, and rapid muscle release (TPR) on reducing IM injection pain compared with the Z-track injection method DESIGN: This triple-blind clinical trial investigated 63 patients who required Methocarbamol injection.
Two, 5-cc methocarbamol injections were given to each patient by the two techniques in two of his/her muscles. In the TPR technique, after applying skin traction and imposing deep pressure on the muscle, the needle was inserted at a 90° angle near the skin and the muscle was released rapidly towards the needle. Hence, the needle was embedded in the muscle. However, muscle release was not applied in the Z-track method. The visual analog scale (VAS) was used to measure pain intensity. For data analysis, T-independent and χ tests were used.
The findings showed that the mean pain score in TPR and Z-track methods was 1.68 ± 1.20 and 3.76 ± 1.42, respectively. The difference was statistically significant.
The results of this study showed that the innovative method (TPR) can be used as a substitute for the Z-track method to reduce IM injection pain.
疼痛管理是护士提供护理的重要组成部分。
本研究旨在调查一种名为皮肤牵引、按压和快速肌肉放松（TPR）的创新方法与Z形轨迹注射法相比在减轻肌肉注射疼痛方面的效果。
这项三盲临床试验对63名需要注射美索巴莫的患者进行了研究。
通过两种技术在每位患者的两块肌肉中各注射两针5毫升的美索巴莫。在TPR技术中，在对皮肤进行牵引并对肌肉施加深部压力后，将针头以90度角靠近皮肤插入，然后将肌肉迅速向针头方向放松。因此，针头被埋入肌肉中。然而，Z形轨迹法不进行肌肉放松。使用视觉模拟量表（VAS）来测量疼痛强度。数据分析采用独立样本t检验和χ检验。
结果显示，TPR法和Z形轨迹法的平均疼痛评分分别为1.68±1.20和3.76±1.42。差异具有统计学意义。
本研究结果表明，创新方法（TPR）可作为Z形轨迹法的替代方法来减轻肌肉注射疼痛。
