Randomized Controlled Trial Comparative Study Clinical TrialComparison of rapid and gradual weaning from external ventricular drainage in patients with aneurysmal subarachnoid hemorrhage: a prospective randomized trial.
The goal of this study was to compare rapid and gradual weaning from external ventricular drainage in patients with aneurysmal subarachnoid hemorrhage (SAH) in a prospective, randomized trial. ⋯ Compared with rapid weaning, gradual, multistep EVD weaning provided no advantage to patients with aneurysmal SAH in preventing the need for long-term shunt placement and prolonged ICU and hospital stays.

Randomized Controlled Trial Clinical TrialRapid and selective cerebral hypothermia achieved using a cooling helmet.
Hypothermia is by far the most potent neuroprotectant. Nevertheless, timely and safe delivery of hypothermia remains a clinical challenge. To maximize neuroprotection yet minimize systemic complications, ultra-early delivery of selective cerebral hypothermia by Emergency Medical Service (EMS) personnel in the field would be advantageous. The authors (W.E. and H.W.) have developed a cooling helmet by using National Aeronautics and Space Administration spinoff technology. In this study its effectiveness in lowering brain temperature in patients with severe stroke or head injury is examined. ⋯ This helmet delivers initial rapid and selective brain cooling and maintains a significant temperature gradient between the core and brain temperatures throughout the hypothermic period to provide sufficient regional hypothermia yet minimize systemic complications. It results in delayed systemic hypothermia, creating a safe window for possible ultra-early delivery of regional hypothermia by EMS personnel in the field.
