The present study aimed to investigate the effect of early deflation of the transradial (TR) band on the vascular outcomes of patients who have undergone coronary angiography through transradial access (TRA). The present controlled clinical trial included all patients who had undergone elective coronary angiography through TRA. The participants (n=70) met the inclusion criteria and were selected using convenient sampling. Then, they were randomly assigned to the intervention and control groups, using block randomization. Data collection tools included a questionnaire on demographic and related clinical data, including the history of diabetes, hypertension, hypercholesterolemia, heart failure and vascular disease, and the checklist of post-angiographic complications, including duration of the procedure, systolic and diastolic blood pressures measured before and after the procedure, and assessments of radial artery occlusion (RAO), hematoma and pain. The intervention group had their TR band on the artery for 1.5 hours after the procedure. Then, the cuff of the band was deflated at a speed of 5 cc every 15 minutes, using a syringe. However, the TR band was kept in place for 2 hours in the control group, followed by the deflation with the same speed. The pressure application time was recorded in both groups from the removal of sheaths until complete hemostasis. The patients with early deflation of the TR band experienced less pain compared to those with typical deflation (P=0.003). However, the variables of hematoma development (P=0.062) and RAO (P=0.371) were not significantly different between the patients with typical and early deflation of the TR band. The present study concluded that the patients with early deflation of the TR band experienced less pain compared to those with typical deflation. Therefore, deflating the TR band after cardiac angiography at 1,5 hours has similar efficacy and safety compare to 2 hours and associated with less reported pain score.
本研究旨在探讨经桡动脉（TR）带早期放气对经桡动脉入路（TRA）行冠状动脉造影患者血管结局的影响。本对照临床试验纳入了所有经 TRA 行择期冠状动脉造影的患者。参与者（n=70）符合纳入标准，并采用便利抽样法入选。然后，他们采用区组随机化方法被随机分配到干预组和对照组。数据收集工具包括一份调查问卷，内容涉及人口统计学和相关临床数据，包括糖尿病、高血压、高胆固醇血症、心力衰竭和血管疾病史，以及经血管造影后并发症检查表，包括手术持续时间、手术前后的收缩压和舒张压以及桡动脉闭塞（RAO）、血肿和疼痛评估。干预组在手术后 1.5 小时将 TR 带置于动脉上。然后，使用注射器以每 15 分钟 5 cc 的速度对带的袖带进行放气。然而，对照组将 TR 带保持原位 2 小时，然后以相同速度进行放气。两组患者从移除护套到完全止血的压力应用时间均有记录。与典型放气相比，早期放气的 TR 带患者疼痛程度较轻（P=0.003）。然而，TR 带典型和早期放气患者的血肿发展（P=0.062）和 RAO（P=0.371）变量无显著差异。本研究得出结论，与典型放气相比，TR 带早期放气患者疼痛程度较轻。因此，与 2 小时相比，在心脏血管造影后 1.5 小时对 TR 带进行放气具有相似的疗效和安全性，并且报告的疼痛评分较低。
