Objectives. The aim of this study is to assess the prevalence and predictive factors for developing chronic access-site (A-S) pain after percutaneous coronary intervention (PCI) via radial artery access. Methods. Data of selected patients (n = 161) who underwent elective PCI were collected prospectively and analysed in 2020. Verbal analogue scale was used to evaluate pain intensity after 12, 24, and 48 h and 3 months after PCI. The univariate logistic regression analysis was used. Results. Pain prevalence decreased from 29% straight after PCI and 54% two hours later to 3.7% following 3 months after procedure. The predictors for A-S pain chronicity are diabetes (OR = 5.77 95% CI (1.07–31.08), ), hematoma (OR = 6.48, 95% CI (1.06–39.66), ), A-S hand neuropathy (OR = 19.93 95% CI (1.27–312.32), ), A-S pain immediately after PCI (OR = 14.60 95% CI (1.63–130.27), ), after 12 h (OR = 17.2 95% CI (1.60–185.27), ), 24 h (OR = 48 95% CI (4.87–487), ), and 48 h (OR = 23.46 95% CI (3.81–144.17), ), and pain intensity immediately after procedure (OR = 3.30 95% CI (1.65–6.60), ), after 2 h (OR = 2.56 95% CI (1.15–5.73), ), after 12 h (OR = 3.02 95% CI (1.70–5.39), ), after 24 h (OR = 3.58 95% CI (1.90–6.74), ), and after 48 h (OR = 2.89 95% CI (1.72–4.87), ). Pain control was performed with Ketoprofen and Ibuprofen as most used NSAIDs. 10 mg of Morphine intravenously was the choice from strong opioids if necessary. Conclusions. The prevalence of chronic A-S pain is 3.7%. Main predictive factors for the A-S pain chronicity are diabetes, hematoma, and persistent pain and pain intensity during 48 h period after PCI.

经Rad动脉通路经皮冠状动脉介入治疗后进入部位疼痛慢性的预测因素

目标。这项研究的目的是评估经radial动脉通路经皮冠状动脉介入治疗（PCI）后发展为慢性进入部位（AS）疼痛的患病率和预测因素。方法。 前瞻性收集选定患者行择期PCI的数据（n = 161），并于2020年进行分析。采用口头类似量表评估PCI术后12、24、48和3个月后的疼痛强度。使用单变量逻辑回归分析。结果。疼痛发生率从PCI后的29％和2小时后的54％下降到术后3个月后的3.7％。AS疼痛慢性病的预测因素是糖尿病（OR = 5.77 95％CI（1.07–31.08），），血肿（OR = 6.48、95％CI（1.06-39.66），）， AS手神经病（OR = 19.93 95％CI（1.27–312.32），）， PCI后立即出现AS疼痛（OR = 14.60 95％CI（1.63–130.27），），在12小时后（OR = 17.2 95％CI（1.60–185.27），）， 24小时（OR = 48 95％CI（4.87–487），）和48小时（OR = 23.46 95％CI（3.81–144.17），），以及手术后立即的疼痛强度（OR = 3.30 95％CI（1.65-6.60），），在2小时后（OR = 2.56 95％CI（1.15-5.73），），在12小时后（OR = 3.02 95％CI（1.70–5.39），），在24小时后（OR = 3.58 95％CI（1.90–6.74），），然后经过48小时（OR = 2.89 95％CI（1.72-4.87），）。用酮洛芬和布洛芬作为最常用的非甾体抗炎药来控制疼痛。如果需要，可以从强阿片类药物中选择10毫克吗啡静脉注射。结论。慢性AS疼痛的患病率为3.7％。PCI后48小时内，AS疼痛慢性的主要预测因素是糖尿病，血肿，持续性疼痛和疼痛强度。
