Increased Intracranial Pressure l: Introduction

Intracranial hypertension is a sustained elevation of intracranial pressure (ICP) above 22 mm Hg. In supine adults, normal ICP is ~7–15 mm Hg.The rigid, nonexpandable cranium contains three components—brain tissue, blood, and cerebrospinal fluid (CSF)—that total ~1,700 mL in a typical adult: 1,400 mL brain (~80%), 150 mL blood (~10%), and 150 mL CSF (~10%). According to the Monro–Kellie doctrine, total intracranial volume is effectively fixed. When one component expands, CSF and venous blood...

Increased Intracranial Pressure ll: Pathophysiology

Increased intracranial pressure (ICP) refers to a potentially life-threatening rise in pressure inside the skull. This usually happens when there is a major change in the volume of brain tissue, blood, or cerebrospinal fluid (CSF) — the three components inside the skull. According to the Monro-Kellie doctrine, if the volume of one component increases, the volumes of the other components must decrease to maintain normal pressure. If this does not happen, ICP rises.The process often begins with...

在创伤性脑损伤的开放式脑部手术 (OC) 后,早期的内压力监测 (ICPM) 与死亡率的增加有关. 在OC后对ICPM指示进行进一步调查是有必要的.

科学领域:

  • 神经外科 神经外科
  • 创伤外科 手术 创伤外科
  • 关键护理医学 关键护理医学

背景情况:

  • 内压力监测 (ICPM) 在治疗严重创伤性脑损伤 (TBI) 方面至关重要.
  • 开放式头骨手术 (OC) 后早期ICPM对死亡率的影响尚不清楚.
  • 这项研究调查了ICPM时间和TBI患者OC后的结果之间的关联.

研究的目的:

  • 为了确定TBI的OC后早期ICPM是否与较低的死亡率有关.
  • 为了比较在72小时内接受ICPM的患者与没有或延迟ICPM的患者之间的结果.

主要方法:

  • 利用了美国外科医生学院创伤质量改善计划的2020-2021年数据.
  • 包括16岁以上的患者,在1级和2级创伤中心接受OC治疗.
  • 使用后勤回归来分析基于ICPM时间的住院死亡率 (早期与没有/延迟).

主要成果:

  • 总共有19,830名患者被分析;29%接受了早期ICPM.
  • 早期ICPM患者的伤害更严重,基线死亡风险更高.
  • 早期ICPM与增加的住院死亡率 (OR 1.35,95% CI 1.24-1.47) 显著相关,即使是在孤立的脑损伤病例中.

结论:

  • 在TBIOC的72小时内放置ICPM与较高的死亡率有关.
  • 在OC后ICPM的当前指示需要进一步审查.
  • 需要进行多中心前性研究,以澄清ICPM的作用,并优化其在TBI管理中的使用.
