Incidence and pathophysiology of severe hyponatraemia in neurosurgical patients
Background:Hyponatraemia is a well-recognised complication of neurosurgical conditions, but the incidence and implications have not been well documented.Objective:To define the incidence, pathophysiology and clinical implications of significant hyponatraemia in several neurosurgical conditions.Metho...

Data were collected by retrospective case note analysis.Results:Hyponatraemia was more common in patients with pituitary disorders (5/81, 6.25%; p = 0.004), traumatic brain injury (44/457, 9.6%; p<0.001), intracranial neoplasm (56/355, 15.8%; p<0.001) and subarachnoid haemorrhage (62/316, 19.6%; p<0.001) than in those with spinal disorders (4/489, 0.81%). The pathophysiology of hyponatraemia was: syndrome of inappropriate antidiuretic hormone secretion (SIADH) in 116 cases (62%) (31 (16.6%) drug-associated), hypovolaemic hyponatraemia in 50 cases (26.7%) (which included patients with insufficient data to assign to the cerebral salt-wasting group (CSWS)), CSWS in nine cases (4.8%), intravenous fluids in seven cases (3.7%) and mixed SIADH/CSWS in five cases (2.7%). Hyponatraemic patients with cerebral irritation had significantly lower plasma sodium concentrations (mean (SD) 124.8 (0.34) mmol/l) than asymptomatic patients (126.6 (0.29) mmol/l) (p<0.0001). Hyponatraemic patients had a significantly longer hospital stay (median 19 days (interquartile range (IQR) 12–28)) than normonatraemic patients (median 12 days (IQR 10.5–15)) (p<0.001).Conclusions:Hyponatraemia is common in intracerebral disorders and is associated with a longer hospital stay. Cerebral irritation is associated with more severe hyponatraemia. SIADH is the most common cause of hyponatraemia and is often drug-associated.]]></description><identifier>ISSN: 0032-5473</identifier><identifier>EISSN: 1469-0756</identifier><identifier>DOI: 10.1136/pgmj.2008.072819</identifier><identifier>PMID: 19417163</identifier><language>eng</language><publisher>London: The Fellowship of Postgraduate Medicine</publisher><subject>Adult ; Aged ; Biological and medical sciences ; Central Nervous System Diseases - surgery ; cerebral salt-wasting syndrome ; Electrolytes ; Epidemiology ; Female ; Fluids ; General aspects ; Humans ; Hypertension ; hyponatraemia ; Hyponatremia - etiology ; Inappropriate ADH Syndrome - etiology ; Laboratories ; Male ; Medical diagnosis ; Medical sciences ; Middle Aged ; Mortality ; Neurosciences ; neurosurgical ; Neurosurgical Procedures - adverse effects ; Plasma ; Public health.
