We report a case of heparin-induced thrombocytopenia (HIT) that was complicated by acute intracerebral hemorrhage (ICH) and bilateral adrenal hemorrhage. In the setting of worsening thrombocytopenia, the risk of expansion of ICH and additional thrombotic events is concerning; hence, we employed plasmapheresis to reduce thrombotic risk. ⋯ This case helps illustrate the utility of plasmapheresis in management of HIT when anticoagulation is contraindicated.

In subarachnoid hemorrhage (SAH), brain injury visible within 48 h of onset may impact on admission neurological disability and 3-month functional outcome. With volumetric MRI, we measured the volume of brain injury visible after SAH, and assessed the association with admission clinical grade and 3-month functional outcome. ⋯ The volume of brain injury visible on DWI and FLAIR within 48 h after SAH is proportional to neurological impairment on admission. Moreover, FLAIR-imaging implicates chronic brain injury-predating SAH-as potentially relevant cause of poor functional outcome.

Reintubation among neurosurgical patients is poorly characterized. The aim of this study was to delineate the rate of reintubation among neurosurgical patients. In addition, we seek to characterize the patient demographic features, comorbidities, and surgical characteristics that may be associated with reintubation among neurosurgical patients. ⋯ Reintubation after neurosurgery is associated with older patients with a greater number of comorbidities. In particular, renal, pulmonary, and severe neurologic comorbidities; longer operative duration; and cranial, rather than spinal, pathology were associated with increased risk for reintubation. These findings may be helpful in triage decisions regarding postoperative intensity of care and monitoring.

Until recently, use of nimodipine in aneurysmal subarachnoid hemorrhage patients unable to swallow required extraction of gel from inside the commercially available capsule. Despite the Black-Box warning against inadvertent intravenous administration, bedside extraction of the gel from the capsule continues to be a common practice in some institutions. The accuracy of bedside extraction has not been formally evaluated. ⋯ Combined with reports of significant patient harm and death with inadvertent intravenous administration, this study suggests that there is no role for bedside extraction of nimodipine in clinical practice.

Sedation and analgesia regimens during targeted temperature management (TTM), after cardiac arrest varies widely, are poorly described in the literature and may have a negative impact on outcome. Since implementing TTM in 2005, we have used moderate-dose sedation and describe our experience with this approach. ⋯ A moderate-dose sedation and analgesia regimen was well tolerated and effective during therapeutic hypothermia after cardiac arrest and is an effective alternative to very deep sedation. We recommend more complete description of sedation and analgesia protocols in future studies, including expanded outcome reporting to include variables affected by sedation therapy. Further study is required to define which sedation approach for TTM may be best.
