Advances in the effects of different compression durations of pneumatic tourniquets on patients after transradial coronary angiography
充气式止血器不同加压时长对桡动脉入路冠脉造影术后患者影响的研究进展

摘要

经桡动脉入路行冠状动脉造影（Coronary Angiography, CAG）及介入治疗（Percutaneous Coronary Intervention, PCI）已成为主流术式，其优势包括术后患者可早期活动、出血并发症少及舒适度提高。术后穿刺点的有效止血是护理关键，充气式桡动脉止血器（如TR-Band）因其压力可控、操作标准而被广泛应用。然而，止血器的加压时长是影响患者术后并发症（如桡动脉闭塞、血肿、疼痛）和舒适度的核心变量。近年来，缩短加压时长的策略成为研究热点。本文旨在综述不同加压时长方案对桡动脉冠脉造影术后患者的止血效果、血管并发症（特别是桡动脉闭塞）、局部并发症及舒适度的影响，并对个体化加压策略的未来研究方向进行展望，以期为临床优化护理实践提供循证依据。

Abstract

The transradial approach for coronary angiography (CAG) and percutaneous coronary intervention (PCI) has become the mainstream technique, offering advantages such as early patient mobilization, reduced bleeding complications, and improved comfort. Effective hemostasis at the puncture site is critical in post-procedural care. Inflatable transradial compression devices (e.g., TR-Band) are widely used due to their controllable pressure and standardized operation. However, the duration of compression is a key factor influencing post-procedural complications (such as radial artery occlusion, hematoma, and pain) and patient comfort. In recent years, strategies to shorten compression duration have become a focus of research. This article reviews the effects of different compression duration protocols on hemostatic efficacy, vascular complications (particularly radial artery occlusion), local complications, and comfort in patients after transradial CAG. It also provides an outlook on future research directions for individualized compression strategies, aiming to offer evidence-based guidance for optimizing clinical nursing practice.
