在澳大利亚和新西兰的重症监护室 (ICU) 中,早期严重的代谢酸性 (MA) 是罕见的,但死亡率很高. 适度的MA更为常见,也与显著的死亡率有关.
科学领域:
- 关键护理医学 关键护理医学
- 腎臟病學 (nephrology) 是一種醫學專業.
- 内部医学 内部医学
背景情况:
- 代谢性酸症 (MA) 是一个常见的ICU并发症.
- 早期识别和分类MA严重程度对于患者的治疗结果至关重要.
- 关于澳大利亚和新西兰ICU中早期MA的发病率和结果的最新数据有限.
研究的目的:
- 为了确定ICU患者早期代谢酸症的发病率,流行率,特征和结果.
- 根据已确定的标准,根据已确定的标准区分严重和中度MA.
- 分析来自澳大利亚和新西兰重症监护协会成年患者数据库的最新数据.
主要方法:
- 在澳大利亚和新西兰重症监护协会成年患者数据库 (2008-2018) 中对成年患者的回顾性分析.
- 适用于早期MA的两个不同的标准:严重 (pH ≤ 7.20,Paco2 ≤ 45 mmHg,HCO3- ≤ 20 mmol/L与SOFA ≥ 4或乳酸≥ 2 mmol/L) 和中度 (pH < 7.30,基量过剩< -4 mmol/L,Paco2 ≤ 45 mmHg).
- 评估发生率,流行率和医院死亡率.
主要成果:
- 查了1,076,087名患者;估计严重的MA发病率为每年39.5 /百万,中度的MA发病率为每年349.2-411.5 /百万.
- 近年来,早期严重的MA影响了1.5%的患者,而中度的MA影响了8.4%.
- 医院死亡率为重症MA的48.3%,中度MA的21.5%.
结论:
- 在澳大利亚和新西兰的ICU中,早期严重的代谢酸性很少发生,但与非常高的死亡率有关.
- 中度代谢性酸性症比较常见,并且还带有显著的死亡风险.
- 这些发现凸显了认知和管理重症和中度早期MA在重症患者的重要性.

Diagnosing Acidosis and Alkalosis
First, the pH level is assessed to determine whether the blood pH is normal (7.35–7.45), low (acidosis), or high (alkalosis).
Next, the PCO2 and...
