IICP 顱內壓升高@ 醫學筆記匯集整理ED Notes :: 痞客邦 | 合法醫療器材資訊網

2021年4月6日—ICPnormal:5-15mmHg/12-20cmH2O.IICP>20mmHg.常用單位是mmHg.1mmHg=1.36cmH2O...因此需在1、2天內慢慢將PaCO2恢復正常...Hypertonicsaline:可快速降低顱內壓,且其效果相當於傳統降腦壓藥物.

* Cushing reflex : HTN, Bradycardia, Respiratory depression

* IICP sign : Headache, Vomiting, Papilledema

Cause of brain edema :

- Cytotoxic cerebral edema : Most commonly seen in cerebral ischemia

- Vasogenic cerebral edema : BBB is disrupted, an extracellular edema.

   most frequently seen around brain tumors and abscess

The distinguishing features of vasogenic edema compared to cytotoxic edema are that

vasogenic edema spares the gyri vs. cytotoxic edema does not,

and that cytotoxic edema follows a vascular distribution vs. vasogenic edema does not.

ICP normal : 5-15 mmHg / 12-20 cm...
