概括

高脑输液压 (CPP) 可能不会使儿科创伤性脑损伤 (TBI) 的结果恶化. 这项研究表明,目前的指导方针可能过于严格,但需要更多的研究来确认TBI患者的安全性和有效性.

科学领域:

儿科神经临界护理
创伤性脑损伤研究研究
脑血管生理学脑血管生理学

背景情况:

低脑输液压 (CPP) 是已知的儿童创伤性脑损伤 (TBI) 预后不良的标志物.
大脑血管自调节通常保持稳定的脑血流,但高CPP可以破坏这一点,增加风险.
对于高CPP的儿科反应的理解较少,这促使对其自调节上限和对结果的影响进行调查.

研究的目的:

描述TBI儿童自我调节的上限.
调查高CPP水平与患者结果之间的关联.

主要方法:

从前性多中心STARSHIP研究 (135名TBI儿童) 的数据分析.
使用视觉和统计方法,探索CPP水平与压力反应率指数 (PRx) 之间的关系.
通过总体平均值,剂量指标和超过值的时间来评估CPP的预后价值.

主要成果:

没有确定自我调节的最终上限;PRx仅在100mmHg以上显著增加.
每小时CPP剂量和超过90mmHg的时间显示出更糟糕的结果的趋势.
热图分析确定了具有不同风险分层的CPP地区.
在患有或没有ARDS或二次出血的患者之间没有观察到显著的CPP差异.

结论:

与预期相反,高CPP水平 (高于当前指导方针) 可能与这组儿科TBI队列的较差结果无关.
观察性质和潜在的混因素需要谨慎解释这些发现.
需要进行前性试验,以最终评估针对儿童TBI管理中更高CPP的安全性和有效性.

Increased Intracranial Pressure l: Introduction

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 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...
