How much is too much drainage from EVD?
How much is too much drainage from EVD?
Drainage should not be turned off for longer than needed, as this can cause the catheter to block. Early signs of over-drainage include headaches, and the neurosurgical team should be notified urgently if the rate of drainage exceeds 10ml per hour or a total of more than 30ml drains in one hour (Woodward et al, 2002).
Which complication of intracranial hemorrhage may require placement of an external ventricular drain?
In most circumstances the increased intracranial pressure and acute hydrocephalus caused by ICH is managed by placement of an external ventricular drain (EVD).
Is EVD serious?
EVD application is frequently complicated by misplacement, hemorrhage, dislodgement, blockage, and most importantly infection (6). EVD infection rate ranges from 0 to 22% (7–9) resulting in a significant increase in cost, hospital stay, morbidity, and mortality (6, 10).
When should EVD be removed?
If the patient tolerates closure of the EVD without recurrent symptoms of hydrocephalus or radiographic evidence of enlarging ventricles, the drain is removed; if it is not, the hydrocephalus usually requires more definitive treatment.
What happens if you drain too much CSF?
It is possible that the puncture of the ventricle or the opening of the dura will result in an intracranial hemorrhage. It is possible that if too much CSF is removed from the ventricles, either during a drainage procedure or when the ventricle is first punctured, the ventricle may collapse and occlude the catheter.
What are the principal risk factors associated with ventriculostomy procedure?
The most significant risk of a ventriculostomy is infection; rates of 27% have been cited,10,18,20,21 although most reported rates are in the 1% to 10% range. Infection rates are similar regardless of procedure location (ICU or the operating room).
What is EVD infection?
Abstract. Objectives External ventricular drain (EVD) insertion is a common neurosurgical procedure. EVD-related infection (ERI) is a major complication that can lead to morbidity and mortality.
How long can you have EVD?
How long will the EVD last? This varies from child to child, depending on the reason why EVD was needed in the first place. However, it is a temporary method of draining CSF and is rarely used for more than 14 days. Your child will need to stay in hospital until the drainage system is removed.
What happens if CSF does not drain properly?
CSF is constantly being made and absorbed by your body. CSF moves through ventricles before it drains out and gets absorbed into your bloodstream. When CSF cannot drain properly, the fluid pressure may cause the ventricles to swell.
What is the major risk with an intraventricular catheter?
These risks include infection, collapse of the ventricles, rapid ventricular drainage, increased potential for subdural hematoma, and subarachnoid hemorrhage.
Does a surgeon’s experience affect the complication rate of external ventricular drain insertion?
Insertion of external ventricular drain (EVD) is a widely accepted, routinely performed procedure for treatment of hydrocephalus and raised intracranial pressure. The purpose of this study was to investigate whether a surgeon’s experience affects the associated complication rate. Methods
Can nursing care improve outcomes in patients with external ventricular drain?
Maintenance, troubleshooting, and monitoring for EVD associated complications has essentially become a nursing responsibility. Accurate and accountable nursing care may have the ability to portend better outcomes in patients requiring CSF drainage.

Does bolt-connected external ventricular drainage (BC-EVD) reduce the risk of complications?
This procedure is life-saving but marred by a high incidence of complication s. It has recently been indicated that bolt-connected external ventricular drainage (BC-EVD) compared to the standard technique of tunnelled EVD (T-EVD) may result in less complications 1).
What is an external ventricular drain (EVD)?
Keywords: External ventricular drain, hydrocephalus, intraventricular hemorrhage, ventriculostomy Insertion of an external ventricular drain (EVD) is arguably one of the most common and most important lifesaving procedures encountered in the neurologic intensive care unit. [ 5 ]
