Implementation of an Online External Ventricular Drain Training Module-An Educational Initiative to Improve Proficiency of Perioperative Health Care Providers: Results of a Retrospective Study.
An external ventricular drain (EVD) training module may improve the knowledge and proficiency of perioperative health care providers (HCPs). ⋯ This online EVD training module was well-received by participants. Overall, improved scores reflect enhanced knowledge among HCPs following completion of the module. The greatest benefit was observed in those reporting less experience and feeling uncomfortable in managing EVDs. The impact on the reduction in EVD-associated adverse events deserves further examination.

Evaluating the Anatomic Spread of Selective Nerve Scalp Blocks Using Methylene Blue: A Cadaveric Analysis.
The modern scalp block consists of local anesthesia injections that target the supraorbital, supratrochlear, zygomaticotemporal, auriculotemporal, and greater and lesser occipital nerves. Limited data exist on the local anesthetic spread that occurs with this technique. This study examines the extent of the spread of a scalp block using methylene blue in a cadaveric model. ⋯ This cadaveric study confirms that the landmark-based technique for scalp blocks consistently stained all 6 nerves involved in scalp innervation. There was significant unintentional spread to the branches of the facial nerve when using the landmark technique.

Release of Hyaluronan in Aneurysmal Subarachnoid Hemorrhage and Cerebral Vasospasm: A Pilot Study Indicating a Shedding of the Endothelial Glycocalyx.
This pilot study investigated plasma concentrations of hyaluronan, heparan sulfate, and syndecan-1 as possible biomarkers for glycocalyx integrity after aneurysmal subarachnoid hemorrhage (aSAH). ⋯ The increased plasma concentrations of hyaluronan after aSAH suggest selective shedding of this component of the glycocalyx. Increased levels of hyaluronan in patients with cerebral vasospasm, underlines a potential role for hyaluronan in vasospasm processes.
