Retinal haemorrhage DDx
Different diagnosis of the causes associated with retinal haemorrhage
Subarachnoid Haemorrhage: Complications
SAH Complications including Neurological deterioration; Seizures; Hyponatremia; Cardiac complications; Re-bleeding; Vasospasm
Subarachnoid Haemorrhage Grading Systems
Subarachnoid Haemorrhage Grading Systems: GCS; Hunt and Hess; WFNS; Fisher; Claassen; Ogilvy and Carter
Subarachnoid Haemorrhage: ICU Management
SAH ICU Management: Follows initial management of SAH; FASTS HUGS IN BED Please applies; certain aspects have particular relevance
Subarachnoid Haemorrhage: Initial Management
SAH initial management includes: resuscitation; specific treatment; supportive care and monitoring; disposition
Subarachnoid Haemorrhage (SAH)
Subarachnoid Haemorrhage (SAH) potentially fatal bleeding into the subarachnoid space, usually due to a ruptured cerebral aneurysm
Subarachnoid Haemorrhage: Prognostication
Subarachnoid Haemorrhage: Prognostication - some factors are modifiable; mortality rates currently ~35%; 15% die prior to reaching hospital; 8-20% long-term dependence
Ventriculitis
Bacterial ventriculitis (BV) is inflammation of the ventricular drainage system, usually due to bacterial infection of the cerebrospinal fluid (CSF)
Vasospasm in Subarachnoid Haemorrhage
Vasospasm in SAH: vasospasm = dynamic narrowing of vessels due to a radiological diagnosis; delayed neurological deterioration (DND) is clinically detected neurological deterioration after stabilisation not due to re-bleeding, may be due to multiple other causes; delayed cerebral ischaemia (DCI) is any neurological deterioration >1 hour that presumed due to ischemia, and other causes excluded
Cerebral Salt Wasting
Cerebral Salt Wasting: also now known as renal salt wasting; hyponatraemia not always required to make diagnosis, but often present; cerebral lesion + excess renal loss of Na+ and Cl-; cerebral lesions: SAH, TBI, tumour
SIADH vs Cerebral Salt Wasting
Syndrome of Inappropriate Antidiuretic Hormone Secretion (SIADH) versus Cerebral Salt Wasting
