镁合金应用于可降解临时起搏电极中的研究进展

Research progress of magnesium alloy applied to degradable temporary pacing electrodes

摘要:

体外循环下心脏直视手术后发生各种缓慢型心律失常比较常见，临时起搏器有助于患者顺利渡过围术期。患者术后自主心律升高到足以维持正常循环功能后停用起搏器，去除起搏导线，但是去除过程中通常会合并一些并发症。所以需设计一种可降解、无需拔除的临时起搏导线解决以上问题。目前已知镁在生物医学应用方面逐渐增多，本文对镁合金作为可降解临时起搏电极材料的研究进展作一综述。

Abstract:

Various slow arrhythmias occur after open heart surgery under cardiopulmonary bypass. Temporary pacemakers help patients to survive during the perioperative period. When the patient’s postoperative autonomic rhythm is increased enough to maintain normal circulatory function, the pacemaker and the pacing lead are removed. However, certain complications are usually associated with the removal process. Designing a temporary pacing lead that is degradable and does not need to be removed may solve above problem. Currently, magnesium is known to be gradually increasing in biomedical applications. This paper reviews the research progress of magnesium alloys as degradable temporary pacing electrode materials.
