Idiopathic intracranial hypertension (IIH), previously known as pseudotumor cerebri and benign intracranial hypertension, is a condition characterized by increased intracranial pressure (pressure around the brain) without a detectable cause. [2] The main symptoms are headache, vision problems, ringing in the ears, and shoulder pain.
The presence of an endotracheal tube and mechanical ventilation alone are not indications of continuous sedation and coma. Only certain conditions such as intracranial hypertension, refractory status epilepticus, the inability to oxygenate with movement, et cetera justify the high risks of medically induced comas. [3]
The term apparent refractory hypertension, as opposed to true refractory hypertension is used by investigators to refer to patients with resistant hypertension based on the number of prescribed medications, without accounting for common causes of pseudo-resistance, ie, inaccurate blood pressure measurements, nonadherence, undertreatment, or white-coat effects.

Intracranial hypertension (IH), also called increased ICP (IICP) or raised intracranial pressure (RICP), refers to elevated pressure in the cranium. 20–25 mmHg is the upper limit of normal at which treatment is necessary, though it is common to use 15 mmHg as the threshold for beginning treatment.
Decompressive craniectomy is frequently performed in cases of resistant intracranial hypertension secondary to several neurological conditions and is commonly followed by cranioplasty. [15] Complications, such as infection and hematomas after cranioplasty occur in roughly about a third of cases. [15]
Refractory hypertension is described by one source as elevated blood pressure unmitigated by five or more concurrent antihypertensive agents of different classes. [154] People with refractory hypertension typically have increased sympathetic nervous system activity, and are at high risk for more severe cardiovascular diseases and all-cause ...
Tadalafil can interact with nitrates used to treat hypertension, angina (chest pain), and other heart problems. This could cause abnormally low blood pressure that may lead to loss of ...
