Causes and nursing countermeasures of hypotension after coronary angiography and stenting
冠状动脉造影及支架术后低血压的原因及护理对策

摘要

目的 分析实施冠状动脉造影和支架植入术后出现低血压的原因并探讨护理对策。方法 选取2022年1月至2023年1月进行冠状动脉造影及支架植入术的患者1000例，对患者术后血压水平及表现等密切观察，及时发现低血压，对发生低血压的原因进行分析，给予患者针对性的处理和护理。结果 1000例患者中出现低血压10例，发生率为10.00%，发生低血压的原因为迷走神经反射、血容量不足、再灌注损伤、心包填塞、药物使用不当、穿刺部位出血、急性冠脉支架内血栓形成。及时对出现低血压的原因进行有针对性的处理，使患者的血压水平均恢复至术前或接近术前。结论 严重的冠心病患者需要采取冠脉造影和支架植入治疗，术后患者可能出现低血压，将有关护理措施做好，并对其进行密切关注，术后尽早将低血压发生情况发现，并实施积极处理，可使低血压发生率显著降低，防止加重病情，进而确保效果及预后的改善。

Abstract

Objective: To analyze the causes of hypotension after coronary angiography and stent implantation and explore the nursing countermeasures.
Methods: 1000 patients who underwent coronary angiography and stent implantation from January 2022 to January 2023 were selected to pay close attention to the postoperative blood pressure level and performance, timely detect hypotension, analyze the causes of hypotension, and provide targeted treatment and care for patients.
Results: Among 1000 patients, 10 had hypotension, the incidence rate was 10.00%. The causes of hypotension were vagal reflex, insufficient blood volume, reperfusion injury, pericardial tamponade, improper drug use, bleeding at puncture site, and acute coronary stent thrombosis. The causes of hypotension should be dealt with in time, and the blood pressure level of patients should be restored to or close to that before operation.
Conclusion  : Patients with severe coronary heart disease need to take coronary angiography and stent implantation treatment. Patients may have hypotension after operation. Relevant nursing measures should be taken and paid close attention to. Early detection of hypotension after operation and active treatment can significantly reduce the incidence of hypotension, prevent aggravation of the disease, and ensure the improvement of the effect and prognosis.
