OBJECTIVES/BACKGROUND: To assess brake reaction time (BRT; key factor in driving ability) in patients receiving transfemoral coronary angiography (CAG). We assumed that patients would have a significantly impaired BRT after the procedure.
A prospective, observational study design was applied. Consecutive patients undergoing right-sided transfemoral CAG as part of the clinical routine were included. An experimental driving simulator was used to determine BRT after receiving a visual stimulus. The subjects applied the brake with their right foot as quickly as possible when a red-light signal appeared. The time interval between stimulus and brake application was taken as BRT. In addition to the total BRT, also its components were determined: neurologic reaction time, foot transfer time and brake travel time. BRT was determined before and 1 day after CAG (pre-post comparison).
71 patients were included in the analysis (58 male, age 61 ± 9 years). Total BRT was 594 ± 188 and 591 ± 198 ms before and after the CAG procedure, respectively (p = 0.270). Similarly, also the BRT components 'foot transfer time' and 'brake travel time' did not show significant differences between the two test occasions. However, neurologic reaction time decreased from 269 ± 67 to 255 ± 64 ms (p = 0.036).
We found no impairment of BRT on the first day after puncture of the right-sided femoral artery in patients undergoing CAG. Therefore, with regard to BRT, it is regarded safe to resume driving from day 1 after CAG. Other factors of driving safety beyond BRT must also be considered.
目的/背景：评估接受经股冠状动脉造影（CAG）患者的制动反应时间（BRT；驾驶能力的关键因素）。我们假设患者在手术后的 BRT 会显著受损。
采用前瞻性、观察性研究设计。纳入连续接受右侧股动脉 CAG 的患者，作为临床常规的一部分。使用实验性驾驶模拟器在接收到视觉刺激后确定 BRT。当出现红灯信号时，受试者用右脚尽快踩下刹车。从刺激到刹车应用的时间间隔被视为 BRT。除了总 BRT 外，还确定了其组成部分：神经反应时间、脚移时间和刹车行程时间。在 CAG 前后（术前术后比较）测定 BRT。
71 例患者纳入分析（58 例男性，年龄 61±9 岁）。总 BRT 分别为 CAG 前后的 594±188ms 和 591±198ms（p=0.270）。同样，BRT 组成部分“脚移时间”和“刹车行程时间”在两个测试时间点之间也没有显著差异。然而，神经反应时间从 269±67ms 下降至 255±64ms（p=0.036）。
我们发现接受 CAG 的患者右侧股动脉穿刺后第一天的 BRT 没有受损。因此，从 CAG 后第一天起，恢复驾驶被认为是安全的，BRT 以外的其他驾驶安全因素也必须考虑。
