Sample from Order Set: Increased Intracranial Pressure (ICP) Management If ICP is greater than 20 mmHg for more than 5 minutes or greater than 30 mmHg for 1 minute: * Assure volume and MABP status as outlined per Order Set using volume and pressors.
In our series, multiple patients showed clinical improvement after medical management of increased intracranial pressure.
These lead to increased intracranial pressure, causing the brain to enlarge.
Comment: Idiopathic intracranial hypertension (also known as benign intracranial hypertension or pseudotumor cerebri) is characterized by increased intracranial pressure and papilledema.
The medial aspect of the temporal bone may fail to develop, resulting in a persistent lateral craniopharyngeal canal (also known as the Sternberg canal) between the middle cranial fossa and the pneumatised inferolateral recess of the sphenoid sinus.3 Idiopathic intracranial hypertension (pseudotumour cerebri) and empty sella syndrome are also known to occur in these patients,2 suggesting that chronically increased intracranial pressure with localised thinning of the bone may also play a role in the pathogenesis of this condition.4
Convulsions in the buffalo could be attributed to focus of irritation in the brain or increased intracranial pressure. Antibiotic (Sulfadiazine + trimethoprim) was given to control any systemic bacterial infection because the drug crosses the blood brain barrier and drug concentration in CSF upto 80% of plasma concentration is achieved.

(2,7,10) Hydrocephalus and increased intracranial pressure, which develop in approximately 25% of cases, may manifest with nausea, vomiting, and papilledema.
D--Mental status changes, such as confusion, restlessness, and coma, are due to inflammation and obstruction of cerebrospinal fluid outflow, which leads to increased intracranial pressure (ICP) (Lauer, 2009).
