Randomized Controlled Trial Comparative StudyThe Brain Relaxation and Cerebral Metabolism in Stroke Volume Variation-directed Fluid Therapy During Supratentorial Tumors Resection: Crystalloid Solution Versus Colloid Solution.
Compared with goal-directed crystalloid therapy, goal-directed colloid therapy during high-risk surgery may improve postoperative outcome. Whether intraoperative fluid therapy based on goal-directed protocol with different types of fluid has distinctive effects on brain relaxation and cerebral metabolism during craniotomy remains unclear. ⋯ In patients undergoing supratentorial tumor resection, goal-directed HES therapy was not superior to goal-directed LR therapy for brain relaxation or cerebral metabolism, although less fluid was needed to maintain the target SVV in the HES-based group than in the LR-based group.

ReviewPostoperative Cognitive Function Following General Versus Regional Anesthesia: A Systematic Review.
The effect of anesthetic technique on postoperative outcomes remains in question. This systematic review compares the role of regional versus general anesthesia, with a particular focus on postoperative cognitive function. Potentially relevant articles were identified by searching publicly available computerized databases for this systematic review. ⋯ Any measure of postoperative cognitive function was accepted as long as it was performed no sooner than 7 days postoperatively. Sixteen studies met inclusion criteria and were included in the final analysis. Three studies showed some difference in cognitive function between regional and general anesthesia, whereas the remaining 13 showed no difference between regional and general anesthesia on postoperative cognitive function.
