For patients with an implanted external ventricular drain, cerebrospinal fluid can be collected from the drain's output. After the sample of fluid is obtained, a battery of tests featuring gram staining will be performed to identify any offending pathogen or infection agent. The test will also determine any resistance the pathogen may have to ...
An external ventricular drain (EVD), also known as a ventriculostomy or extraventricular drain, is a device used in neurosurgery to treat hydrocephalus and relieve elevated intracranial pressure when the normal flow of cerebrospinal fluid (CSF) inside the brain is obstructed.
The most definitive way of measuring the intracranial pressure is with transducers placed within the brain. A catheter can be surgically inserted into one of the brain's lateral ventricles and can be used to drain CSF (cerebrospinal fluid) in order to decrease ICPs. This type of drain is known as an external ventricular drain (EVD). [10]
In more severe cases an external ventricular drain may be required to maintain ICP and evacuate the hemorrhage, and in extreme cases an open craniotomy may be required. [ 2 ] [ 14 ] In cases of unilateral IVH with small intraparenchymal hemorrhage the combined method of stereotaxy and open craniotomy has produced promising results.
[3] [4] Symptoms can vary dramatically depending on the severity (how much blood), acuity (over what timeframe), and location (anatomically) but can include headache, one-sided weakness, numbness, tingling, or paralysis, speech problems, vision or hearing problems, memory loss, attention problems, coordination problems, balance problems ...
Most shooting pains, leg cramps and charley horses are temporary. Sometimes, they signal other problems. What you need to know about leg cramps, sudden pain and when to see a doctor
Symptoms may include skin that feels tight, the area feeling heavy, and joint stiffness. [1] Other symptoms depend on the underlying cause. [2] Causes may include venous insufficiency, heart failure, kidney problems, low protein levels, liver problems, deep vein thrombosis, infections, kwashiorkor, angioedema, certain medications, and lymphedema.
A cramp is a sudden, involuntary, painful skeletal muscle contraction [1] [2] or overshortening associated with electrical activity; [3] while generally temporary and non-damaging, they can cause significant pain and a paralysis-like immobility of the affected muscle.
