概括
在接受米特拉置换手术的患者中,重复远程缺血预调 (mRIPC) 显著降低了心肌和肺损伤. 这项研究提供了mRIPC在门手术中的临床应用的证据.
科学领域:
- 心脏病学 心脏病学
- 心血管外科心血管外科
- 关键护理医学 关键护理医学
背景情况:
- 远程缺血预制 (RIPC) 已经证明了器官保护作用,但单一协议的临床结果仍然不确定.
- 修改,重复的RIPC (mRIPC) 协议的心肺保护作用尚未得到充分证实.
- 中心置换手术 (MVR) 存在心肌和肺部并发症的风险.
研究的目的:
- 调查修改远程缺血预制 (mRIPC) 方案在选择性心肌置换手术 (MVR) 期间预防心肌和肺损伤的疗效.
- 评估重复的mRIPC对心脏生物标志物,炎症媒介和急性肺损伤 (ALI) 的影响.
主要方法:
- 一个单中心,随机对照试验,涉及86名接受MVR手术的患者.
- 患者被随机分配到接受mRIPC (手术前24小时,12小时和1小时进行5分钟缺血/5分钟再输血的三次循环) 或对照组.
- 主要终点是血清心脏素I (cTnI);次要终点包括其他心脏酶,炎症标志物,内性得分和ALI发生率.
主要成果:
- 与对照组相比,mRIPC在手术后显著降低了cTnI,CK-MB和LDH的血清度 (p < 0.01).
- 在mRIPC组中,急性肺损伤 (ALI) 的发生率明显较低 (32.6%对51.2%,p=0.039),PaO2/FiO2比率有所改善.
- 手术后mRIPC降低了IL-6和TNF-α水平,增加了IL-10水平,表明炎症减少.

01:22Mitral Valve Prolapse II: Assessment and Management
IntroductionA range of clinical features characterizes Mitral Valve Prolapse (MVP), but it is important to note that many individuals with MVP are asymptomatic and may remain so throughout their lives. For those who do exhibit symptoms, the following are the key clinical features:Palpitations: This is a common symptom where individuals feel an irregular or rapid heartbeat. Palpitations in MVP are often due to arrhythmias such as premature ventricular contractions or supraventricular tachycardia.
01:26Mitral Stenosis III: Medical Management
Mitral stenosis, a condition marked by the narrowing of the mitral valve, necessitates an integrated approach for effective management. This approach includes preventative measures, medical therapy, and surgical interventions to reduce symptoms and prevent complications.PreventionPrevention of mitral stenosis primarily focuses on reducing the incidence of bacterial infections, particularly streptococcal infections, which can lead to rheumatic fever and subsequent valvular damage.
