术后高血糖水平增加了心脏外科手术患者的90天死亡风险. 超过119 mg/dL的水平与更糟糕的结果和更长的住院时间有关.
科学领域:
- 心脏病学 心脏病学
- 密集护理医学 密集护理医学
- 代谢障碍 代谢障碍 代谢障碍
背景情况:
- 术后血糖控制对于心脏手术需要体外循环 (ECC) 的心脏病患者至关重要.
- 低血糖和高血糖都存在风险,但最佳的血糖范围仍未定义.
- 这项研究调查了经过ECC辅助心脏开放手术的患者的血糖水平和死亡率之间的关联.
研究的目的:
- 检查手术后血糖水平与经过ECC的患者90天死亡率之间的关系.
- 为了确定血糖升高与不良结果相关的潜在值.
- 评估血糖对住院和ICU停留时间的影响.
主要方法:
- 利用了MIMIC-IV数据库 (v2.2),包括4033名接受ECC辅助心脏开放手术的患者.
- 根据ICU入院后24小时内测量的血糖,将患者分为四分之一.
- 采用了卡普兰-梅尔生存分析,多变量考克斯回归和限制立方支线 (RCS) 曲线分析.
主要成果:
- 较高的血糖水平与90天死亡率的增加显著相关.
- 观察到一种非线性关系,转折点为119 mg/dL (P < 0.05).
- 超过119 mg/dL的血糖水平与明显更高的死亡风险和长时间住院/ICU相关.
结论:
- 手术后血糖升高与ECC患者90天死亡率的增加有关.
- 血糖水平为119 mg/dL的值表明90天术后死亡风险显著增加.
- 保持最佳的血糖控制对于改善这种患者群体的治疗结果至关重要.
