背景情况:
- 术后正极呼气压 (PEEP) 通常设置为5厘米H2O.
- 在心脏手术患者中,较高PEEP水平的临床益处尚未得到充分证实.
- 这项研究研究了心脏外科手术患者的中度与常规较低PEEP.
研究的目的:
- 为了比较中度PEEP (≥7厘米H2O) 与传统较低PEEP (<7厘米H2O) 对以患者为中心的结果的影响.
- 评估不同PEEP策略对机械通风持续时间和重症监护室 (ICU) 停留时间的影响.
- 评估二次结果,包括氧化和需要倾斜定位的需要.
主要方法:
- 心脏手术患者的单中心回顾性研究 (2022年6月 - 2023年5月).
- 倾向-得分匹配 (PSM) 用于在不同组之间平衡基线特征.
- 主要结局:机械通风持续时间和ICU停留时间. 二次结果:PaO2/FiO2比率和倾斜定位要求.
主要成果:

Aortic Regurgitation III: Medical Management
598
Aortic regurgitation (AR) is when the aortic valve does not close or seal properly, leading to backward blood circulation from the aorta into the left ventricle during diastole. Common causes of AR include rheumatic heart disease, congenital valve defects, and aortic root dilation. Managing AR requires a multifaceted approach to alleviate symptoms, preserve left ventricular function, and address the underlying cause of the regurgitation. Patients with symptomatic AR or significant left...

Patients with hypertrophic cardiomyopathy (HCM) and left ventricular outflow tract (LVOT) obstruction who remain symptomatic despite optimal medical therapy may undergo a septal myectomy (Morrow procedure). This procedure involves excising a portion of the hypertrophied septum below the aortic valve using a heart-lung machine to improve blood flow through the LVOT. Effective preoperative and postoperative nursing management ensures successful patient outcomes, minimizes complications, and...
