What conditions are extra-ventricular drainage suitable for?
1.After transventricular surgery or intracerebroventricular tumor resection, it should be drained for 3 days-5 days.
2, Intraventricular hemorrhage or cerebral hemorrhage broken into the ventricle is not suitable for surgery.
3.Cerebrospinal fluid leakage after craniotomy or spinal membrane bulge repair.
4.Posterior cranial fossa tumor is critical, and the patient’s body condition is too weak to tolerate surgery.
5.Patients who cannot operate immediately after ventriculography.
6, ventricular system lesions or other causes of hydrocephalus, in order to predict the effect of shunt surgery, the ventricular drainage can be observed first, to determine whether there are indications for shunt surgery.
7, intracranial infection, inoperable or abscess broken into the ventricle, can drain out the inflammatory cerebrospinal fluid, but also can inject effective antibiotics to treat.
What is the effect of extraventricular drainage on patients with traumatic high cranial pressure?
1.Drainage of some cerebrospinal fluid to reduce intracranial pressure.
2.Intracranial pressure monitoring can be performed through the drainage system, and cerebral edema fluid can be drained out.
3.After trauma and cerebral ischemia, lactic acid and metabolites in brain tissue and cerebrospinal fluid can also be drained out, which is beneficial to the functional recovery of brain tissue.
4.For patients with combined intracerebroventricular blood accumulation, intracerebroventricular blood can be drained out to reduce the stimulation of blood to the ventricular canal membrane, prevent blood from flowing into the subarachnoid space to stimulate vasospasm, and prevent obstructive or traffic hydrocephalus caused by blood clots.
Matters that should be noted for ventricular drainage.
1, strict aseptic operation, the ventricular drainage tube should be placed at a moderate depth and fixed to prevent dislodgement and maintain patency.
2, prevention of infection, routine application of antibiotics, daily replacement of drainage bottles.
3, the height of the drainage tube is generally 10cm-15cm above the ventricular level, such as blood cerebrospinal fluid can be lowered as appropriate, and pay attention to changes in the color of the drainage fluid, record the daily drainage flow.
4, drainage time generally does not exceed 1 week-2 weeks.
5, before terminating the drainage can be closed to observe 24h-48h, if the cranial pressure is still high, can be changed to internal shunt or discretionary dehydration agents.
6, we should always closely observe the changes in the condition and timely treatment.
