The effects of a relaxation technique (RT) on anxiety, vital signs, procedure length, and amount of diazepam given were examined in patients undergoing cardiac catheterization (CC). Forty patients were randomly assigned to an experimental (RT) or a control (no RT) group. No significant differences were found between groups in pre-CC or post-CC State-Trait Anxiety Inventory (STAI) scores, vital signs, or procedure length. The experimental group received significantly less diazepam, and their STAI scores declined significantly.
在接受心导管插入术（CC）的患者中，研究了一种放松技术（RT）对焦虑、生命体征、手术时长以及地西泮给药量的影响。40名患者被随机分为实验组（RT）或对照组（无RT）。两组在CC术前或术后的状态-特质焦虑量表（STAI）评分、生命体征或手术时长方面均未发现显著差异。实验组接受的地西泮显著较少，且他们的STAI评分显著下降。
