The Physiologic Effects of Indomethacin Test on CPP and ICP in Severe Traumatic Brain Injury (sTBI).
Refractory intracranial hypertension (RICH) is associated with high mortality in severe traumatic brain injury (sTBI). Indomethacin (INDO) can decrease intracranial cerebral pressure (ICP) improving cerebral pressure perfusion (CPP). Our aim was to determine modifications in ICP and CPP following INDO in RICH secondary to sTBI. ⋯ INDO appears effective in reducing ICP and improving CPP in RICH. INDO test could be a useful tool in identifying RICH patients with favorable outcome. Future studies are needed.

Central pontine and extrapontine myelinolysis (CPEPM) is a rare but potentially fatal complication after orthotopic liver transplantation (OLT). The aim of this study was to identify risk factors for development of CPEPM after OLT and to assess patient outcome. ⋯ High MELD score patients undergoing OLT, receiving massive perfusions of Na-rich products, experiencing surgery-related hemorrhagic complication and important fluctuations of Na are at risk of developing CPEPM. Therefore careful monitoring of natremia in the perioperative period and use of water-free perfusion in case of massive blood-products transfusion are critical points of this patient management.

Subarachnoid hemorrhage (SAH) is a devastating disease. Nimodipine is the only medical treatment shown to improve outcome of SAH patients. Human albumin (ALB) may exert neuroprotection in SAH. However, current usage of ALB in SAH is not known. We conducted an international survey of clinicians involved in the care of SAH patients to determine current practice of ALB administration in SAH. ⋯ In this survey we found that ALB administration in SAH patients is common and influenced by several factors. Majority of respondents support a randomized clinical trial to determine the safety and efficacy of ALB administration in SAH patients.

Patients suffering from severe traumatic brain injury (TBI) often develop secondary brain lesions that may worsen outcome. S100B, a biomarker of brain damage, has been shown to increase in response to secondary cerebral deterioration. The aim of this study was to analyze the occurrence of secondary increases in serum levels of S100B and their relation to potential subsequent radiological pathology present on CT/MRI-scans. ⋯ Secondary increases in serum levels of S100B, even as low as ≥0.05 μg/L, beyond 48 h after TBI are strongly correlated to the development of clinically significant secondary radiological findings.

Apnea Testing for Brain Death in Severe Acute Respiratory Distress Syndrome: A Possible Solution.
A 42-year-old man with a subarachnoid hemorrhage complicated by anoxic brain injury, respiratory failure requiring mechanical ventilation, and severe acute respiratory distress syndrome (ARDS) presented a clinical conundrum for safe apnea testing in brain death determination due to profound hypoxemia. ⋯ A recruitment maneuver and CPAP valve may be used in severe ARDS for safe apnea testing in brain death determination.
