麻醉术前需要停用的降压药分析

Analysis of antihypertensive drugs that need to be discontinued before anesthesia surgery

手术前先进行麻醉,可以通过麻醉药物实现对患者中枢神经以及周围神经系统功能的可逆性抑制。但是麻醉具有一定的危险性,特别是本身存在心脑血管疾病的患者,其危险性明显增加。高血压患者需要长期使用降压药物。由于不同降压药物的作用特点不同,因此,高血压患者麻醉术前是否需要停止使用降压药物以及需要停用的药物种类需要得到临床的特别关注。此文对高血压疾病特点及其药物治疗、麻醉的作用、麻醉术前需要停用的降压药物等方面进行总结和分析,希望引起临床足够的重视。在临床实践工作中,通常在全身麻醉或椎管内麻醉手术前会有麻醉医生以及手术室护士访视,开展术前检查评估。是否停用降压药需要看患者使用的药物种类,并且需要麻醉医生与心脏科医生共同评估判断。

Preoperative anesthesia can achieve reversible inhibition of the patient's central nervous system and peripheral nervou system function through anesthetic drugs. However, anesthesia has certain risks, especially for patients with inherent cardiovascular andcerebrovascular diseases, its risk is significantly increased. Patients with hypertension need to use antihypertensive drugs for a long time.Due to the characteristics of different antihypertensive drugs, for hypertensive patients, the need to stop using antihypertensive drugsbefore anesthesia and the types of drugs that need to be stopped need special clinical attention. This article summarizes and analyzes thecharacteristics of hypertension and its drug treatment, the role of anesthesia, and the antihypertensive drugs that need to be discontinuedbefore anesthesia surgery, hoping to attract sufficient attention. In clinical practice, surgery is usually performed under general anesthesiaor spinal anesthesia, with visits from anesthesiologists and operating room nurses before anesthesia to conduct preoperative examinationsand evaluations. Whether to discontinue antihypertensive drugs depends on the type of medication used by the patient, and requires jointevaluation and judgment by anesthesiologists and cardiologists.
