Randomized Controlled TrialCerebral effect of acute normovolemic hemodilution during brain tumor resection.
Acute normovolemic hemodilution (ANH) is used in major surgery expected to be accompanied by excessive blood loss. Reducing the hemoglobin content may disturb cerebral oxygen balance. The aim of this study was to assess the effect of ANH on cerebral oxygen balance in patients subjected to brain tumor resection. ⋯ ANH and allogenic blood transfusion used in this study design were accompanied by comparable cerebral oxygenation parameters in patients subjected to brain tumor resection.

Randomized Controlled Trial Comparative StudyThe effect of pressure-controlled ventilation on pulmonary mechanics in the prone position during posterior lumbar spine surgery: a comparison with volume-controlled ventilation.
When an anesthetized patient is turned to the prone position using the Wilson frame, dynamic compliance (Cdyn) decreases and peak airway pressure (Ppeak) increases. As pressure-controlled ventilation (PCV) decreases the Ppeak, this prospective, randomized study was designed to compare the effect of PCV and volume-controlled ventilation (VCV) on lung mechanics in the prone position using the Wilson frame during posterior lumbar spine surgery. ⋯ PCV provides lower Ppeak compared with VCV when the ventilator is set to deliver the same tidal volume and variable respiratory rate to maintain a constant end-tidal carbon dioxide tension in patients undergoing posterior lumbar spine surgery in the prone position using the Wilson frame.
