Cerebral oximetry during carotid clamping: is blood pressure raising necessary?

Background: Carotid endarterectomy is subject to a significant risk of intraoperative stroke. Anesthetic management of patients must provide optimal monitoring of cerebral blood perfusion to establish whether intraluminal carotid shunting is necessary. Cerebral oximetry (regional cerebral oxygen saturation, rSO2) measurement can ascertain whether brain perfusion is adequate.

Prolonged independent lung respiratory treatment after single lung transplantation in pulmonary emphysema.

Single lung transplantation (SLT) is now successfully used in patients with severe emphysema. Mechanical imbalance between the native emphysematous and the healthy transplanted lung can be easily managed, unless severe graft failure occurs, leading to acute respiratory failure. Emergency retransplantation has been used in this setting, since the conventional approach to adult respiratory distress syndrome (ARDS) (mechanical ventilation and positive end-expiratory pressure [PEEP]) fails, due to the mechanical discrepancy between the two lungs.
