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.

Propofol infusion syndrome (PRIS) is a rare, but lethal complication of high-dose propofol infusions. We undertook this study to evaluate the incidence of PRIS in a cohort of patients with severe head trauma and its relation to the use of vasopressors. ⋯ Awareness and early recognition of PRIS in critically ill neurosurgical patients on vasopressors and daily screening for creatine kinase elevation, unexplained acidosis, or electrocardiographic changes may reduce the incidence and case-fatality.

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.

To determine the rate of subacute recanalization and reocclusion and its effect on clinical outcomes among patients with ischemic stroke treated with endovascular treatment. Subacute recanalization and reocclusion occurring hours after completion of the intravenous or intra-arterial thrombolysis for acute ischemic stroke has been reported in anecdotal cases. ⋯ We found that new or additional recanalization occurs in one-fourth of the patients within 24 h of endovascular treatment and is not associated with any adverse consequences. Subacute reocclusion occurs infrequently after endovascular treatment.

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.
