概括

心脏手术后的血糖变化 (GV) 与死亡率的增加有关. 这种标志物可能有助于预测患者的结果与现有的临床因素一起.

科学领域:

心脏病学心脏病学
密集护理医学密集护理医学
代谢监测代谢监测

背景情况:

血糖变化 (GV) 可能比绝对葡萄糖水平更好地反映外科手术期间的代谢不稳定性.
大型心脏手术后GV的预后意义尚未确立.

研究的目的:

为了调查GV与重症监护室 (ICU) 重症心脏手术后患者的死亡风险之间的关联.
评估与已确定的临床风险因素相比,GV的预测性能.

主要方法:

使用MIMIC-IV数据库对2943名接受冠状动脉旁路移植或门手术的ICU患者进行了回顾性分析.
GV计算为在ICU停留期间葡萄糖变化系数;主要结局30天死亡率.
多变量考克斯回归,IPTW和机器学习模型 (XGBoost) 用于分析和预测.

主要成果:

更高的GV独立地与30天,90天和360天死亡率的增加有关.
对于最高与最低GV四分位数的危险比率为6.72 (30天),2.46 (90天) 和2.19 (360天).
结合GV的XGBoost模型实现了30天死亡率的优异歧视 (AUC0.845),与单独GV的XGBoost模型相比 (AUC0.686).

结论:

血糖变异性升高是心脏手术后ICU患者短期和长期死亡率的独立预测因素.
经手术后风险分层的GV可以作为一个有价值的补充标记.

关键词:

心脏外科手术是一项心脏手术.血糖的可变性血糖的可变性在ICU中,医生会对患者进行治疗.这就是MIMIC-IV.死亡率死亡率死亡率

Cardiomyopathy VII: Pre and Post Operative Nursing Management

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...
