Comparison of arterial blood pressure and cardiac index-based hemodynamic management on cognitive function in elderly patients undergoing spinal surgery: a randomized clinical trial.

BACKGROUND: Postoperative delayed neurocognitive recovery (DNR) is frequent in elderly patients. Prevention of DNR is essential to achieve a better postoperative outcome

Pulse Pressure Variation and Weight-Loss Percentage Predict Hypotension After Anesthesia Induction in Neurosurgery Patients: A Prospective, Observational, Blinded Study.

Background: Hypotension after anesthesia induction is a common problem and is partly related to patient volume status. The present study aimed to investigate the correlation between blood pressure change and pulse pressure variation (PPV), and percentage of weight loss while determining threshold for hypotension by receiver operating characteristic analysis

Effect of Lumbar Puncture in Patients with Aneurysmal Subarachnoid Hemorrhage Treated Microsurgically or Endovascularly

Objective: The aim of this study was to evaluate the effect of treatment modality (surgical clipping vs. endovascular coiling) and lumbar puncture (LP) in patients with aneurysmal subarachnoid hemorrhage (SAH) based on neurologic status on admission and clinical outcome
