Neurocritical care

Predicting extubation failure (EF) is one of the most challenging aspects of critical care medicine. The literature on EF in neurocritical care patients is very scarce. We sought to determine the ability of traditional weaning parameters to predict EF in neurocritical patients. ⋯ In this sample of neurocritical care patients undergoing extubation trial, traditional weaning parameters do not predict extubation failure.

To determine the safety and tolerability of super-selective intra-arterial magnesium sulfate in combination with intra-arterial nicardipine in patients with cerebral vasospasm after subarachnoid hemorrhage. ⋯ Administration of intra-arterial magnesium sulfate in combination with nicardipine was well tolerated in patients with subarachnoid hemorrhage and cerebral vasospasm without a significant change in MAP and ICP. The efficacy of this combination therapy should be evaluated in a larger, controlled setting.

Plateau waves often develop in neurointensive care patients. They are sudden increases in intracranial pressure (ICP) that lead to dramatic decreases of cerebral perfusion pressure (CPP) and can therefore contribute to ischemic secondary brain insult. The aim of this study was to analyze the occurrence of plateau waves in head injured patients requiring neurocritical care, their relation with cerebral autoregulation and impact on outcome. ⋯ Plateau waves are frequent phenomenon. They are not associated with worse outcome unless they lead to sustained intracranial hypertension.

The objectives of this study are to determine the incidence of symptomatic venous thromboembolism (VTE) in neurosurgery intensive care unit (NSICU) patients with spontaneous or traumatic intracranial hemorrhage and to identify the common VTE risk factors by injury type. ⋯ This is the first study to determine symptomatic VTE incidence and to identify common risk factors by injury type in nontumor patients who are not routinely screened with venous duplex ultrasonography but receiving early IPC and LDUH. Further studies are needed to determine the overall incident of symptomatic and nonsymptomatic VTE and independent risk factors for VTE events in NSICU patients.

Intracerebral hemorrhage (ICH) is the most feared complication of oral anticoagulant therapy (OAT). While anticoagulated patients have increased severity of bleeding following ICH, they may also be at increased risk for thromboembolic events (TEs) given that they had been prescribed OAT prior to their ICH. We hypothesized that TEs are relatively common following ICH, and that anticoagulated patients are at higher risk for these complications. ⋯ The incidence of TEs in an unselected ICH population was 7.2%. Patients with OAT-related ICH were not at increased risk of TEs.
