The aim of this study was to investigate the prevalence of hypozincaemia after aneurysmal subarachnoid haemorrhage (aSAH) and its association with delayed cerebral ischemia and functional outcome.METHODS: We retrospectively analysed a cohort of 384 patients with SAH admitted to the Neurointensive Care Unit at Rigshospitalet, Copenhagen, Denmark, in whom at least one measurement of plasma zinc concentration was done during the hospital stay. Hypozincaemia was defined as at least one measurement of plasma zinc below 10 μmol/L. Potential associations between hypozincaemia, demographic variables and functional outcome after aSAH were analysed in multivariable logistic regression models.RESULTS: Hypozincaemia was observed in 67{\%} (n = 257) of all patients and occurred within 7 days in more than 95{\%} of all hypozincaemic patients. In a multivariable model, severe SAH (WFNS 3-5; OR 4.2, CI 2.21-8.32, p < 0.001) and Sequential Organ Failure Assessment (SOFA) score on the day of admission (OR 1.24, CI 1.11-1.40, p < 0.001) were independently associated with hypozincaemia.
