Adult respiratory distress syndrome (ARDS) can be a common problem associated with the treatment of acute brain injury. High frequency oscillatory ventilation (HFOV) is a developing therapy for the treatment of ARDS in adult patients that can be life saving. However, often patients with acute, severe brain injury demonstrate intracranial hypertension (hICP) due to a variety of injuries (e.g., traumatic brain injury, mass lesion, acute hydrocephalus). There is concern over the use of HFOV due to its effects on intracranial pressure in patients with hICP. ⋯ HFOV did not cause unmanageable or sustained increases in ICP in our series of patients. It appears HFOV may be a relatively safe and effective means of oxygenating patients with severe ARDS and concomitant hICP secondary to acute brain injury.

Randomized Controlled Trial
Continuous low dose diclofenac sodium infusion to control fever in neurosurgical critical care.
Aim of this randomized prospective clinical trial is to compare two methods of antipyretics and evaluate their efficacy in controlling fever during the acute phase of brain damage. ⋯ Low dose DCF infusion is a potential useful strategy for a successful control temperature better than intermittent NSAIDs dosing, minimizing potentially brain-damaging effects of fever.

Hyponatremia after traumatic brain injury (TBI) may influence neurological function and treatment. A causal relationship between elevated serum concentrations of Type B natriuretic peptide (BNP) and hyponatremia has been implied after subarachnoid hemorrhage and other neurosurgical disorders, although the source of BNP has not been identified. We evaluated if hyponatremia and increased BNP occur after TBI and if BNP is produced/released by the brain within 24 h after injury. ⋯ In this pilot study BNP is elevated within 24 h after TBI in some patients. However, it does not originate from the brain and increased NT-proBNP concentrations are not consistently associated with hyponatremia or increased urinary sodium loss.

Levetiracetam (LEV) is used in the setting of acute brain injury for seizure treatment or prophylaxis but its safety and efficacy in this setting is unknown. ⋯ The results of this study suggest that LEV is a frequently used AED in the setting of acute brain injury and that it may be a desirable alternative to phenytoin. Prospective studies evaluating the long-term safety, efficacy and outcomes of LEV in this setting are indicated.

The Guglielmi Detachable Coil introduced by the Boston Scientific Corporation has been widely used for endovascular coiling of aneurysm. Recently, Sapphire platinum detachable coils (eV3, Irvine, CA) have been introduced for aneurysm coiling. Herein, we report our clinical experience with the Sapphire coil to evaluate the incidence of coil related complications and the rate of aneurysm occlusion. ⋯ The Sapphire coil could safely be used in the treatment of both ruptured and unruptured aneurysms. However, multi-diameter non-stretch resistant coils may be associated with coil stretching when used in conjunction with a stent. Further study is still required for definitive results.
