Randomized Controlled TrialGoal-directed Fluid Therapy Versus Conventional Fluid Therapy During Craniotomy and Clipping of Cerebral Aneurysm: A Prospective Randomized Controlled Trial.
Fluid imbalance is common after aneurysmal subarachnoid hemorrhage and negatively impacts clinical outcomes. We compared intraoperative goal-directed fluid therapy (GDFT) using left ventricular outflow tract velocity time integral (LVOT-VTI) measured by transesophageal echocardiography with central venous pressure (CVP)-guided fluid therapy during aneurysm clipping in aneurysmal subarachnoid hemorrhage patients. ⋯ Compared with CVP-guided fluid therapy, transesophageal echocardiography-guided GDFT maintains MAP with lower volumes of intravenous fluid in patients undergoing clipping of intracranial aneurysms with no adverse impact on postoperative complications.

Observational StudyA Pilot Prospective Observational Study of Cerebral Autoregulation and 12-Month Outcomes in Children With Complex Mild Traumatic Brain Injury: The Argument for Sufficiency Conditions Affecting TBI Outcomes.
The relationship between cerebral autoregulation and outcomes in pediatric complex mild traumatic brain injury (TBI) is unknown, and explored in this study. ⋯ Two-thirds of children with complex mild TBI experienced incomplete functional recovery at 1 year. The co-occurrence of hypotension and cerebral autoregulation may be a sufficiency condition needed to affect TBI outcomes.

ReviewValue-based Care and Quality Improvement in Perioperative Neuroscience.
Value-based care and quality improvement are related concepts used to measure and improve clinical care. Value-based care represents the relationship between the incremental gain in outcome for patients and cost efficiency. It is achieved by identifying outcomes that are important to patients, codesigning solutions using multidisciplinary teams, measuring both outcomes and costs to drive further improvements, and developing partnerships across the health system. ⋯ Validated, standardized core outcome sets for perioperative neuroscience are currently lacking, but neuroanesthesiologists can consider using traditional clinical indicators, patient-reported outcomes measures, and perioperative core outcome measures. Several examples of bundled care solutions have been successfully implemented in perioperative neuroscience to increase value; for example, enhanced recovery for spine surgery, delirium reduction pathways, and same-day discharge craniotomy. This review proposes potential individual- and system-based solutions to address barriers to value-based care and quality improvement in perioperative neuroscience.

Chronic Use of Angiotensin Converting Enzyme Inhibitors and/or Angiotensin Receptor Blockers is Not Associated With Stroke After Noncardiac Surgery: A Retrospective Cohort Analysis.
Inhibition of the renin-angiotensin-aldosterone pathways reduces blood pressure and proliferation of vascular smooth muscles and may therefore reduce the risk of stroke. We tested the hypothesis that patients taking angiotensin converting enzyme inhibitors (ACEIs) or angiotensin receptor blockers (ARBs) for at least 6 months have fewer postoperative strokes after non-neurological, noncarotid, and noncardiac surgeries than those who do not. ⋯ We did not detect an effect of chronic ACEI/ARB use on postoperative strokes in patients who had non-neurological, noncarotid and noncardiac surgery; however, power was extremely limited.
