Patients with subarachnoid hemorrhage (SAH) frequently need a ventriculostomy for treatment of hydrocephalus. In some ICU practices, a ventriculostomy is considered a relative contraindication for subcutaneous heparin. We studied the risk of ventriculostomy-associated hemorrhage and deep venous thrombosis (DVT) in patients with anticoagulant prophylaxis. ⋯ In our cohort, the risk of VTE was reduced by more than half in patients receiving chemoprophylaxis. Ventriculostomy-associated hemorrhages were rare and minor. Anticoagulant thromboprophylaxis is mostly safe and required in aneurysmal SAH.

Hospital-acquired infections (HAIs) result in excess morbidity, mortality, and resource consumption. Immobilized, ventilator-dependent ICU patients are at the highest risk of HAI. ⋯ Combining a multidisciplinary approach with rigorous analysis of objective data, we decreased total HAIs by 53 % over 18 months. Key drivers were decreased urinary catheter use and decreased patient transport from the ICU for imaging.

Patients with traumatic brain injuries (TBIs) have an increased risk of developing a deep vein thrombosis (DVT), but the risk of hemorrhage expansion with intracranial monitoring devices remains unknown. We sought to determine the safety of chemical DVT prophylaxis in severe TBI patients with invasive intracranial pressure monitors. ⋯ We conclude that DVT prophylaxis with either LMWH or UH is safe with intracranial pressure monitors in place.

Cognitive dysfunction can be a long-term complication following subarachnoid hemorrhage (SAH). Preclinical models have been variously characterized to emulate this disorder. This study was designed to directly compare long-term cognitive deficits in the context of similar levels of insult severity in the cisterna magna double-blood (DB) injection versus prechiasmatic blood (PB) injection SAH models. ⋯ Both SAH models caused long-term cognitive deficits in the context of similar insult severity. Cognitive deficits differed between the two models, as did distribution of histologic injury. Each model offers unique properties and both models may be useful for study of SAH-induced cognitive deficits.
