Inter-hemispheric cerebral saturation differences during thoracic surgery with lateral head positioning

Reduced cerebral oxygen saturation during thoracic surgery predicts early postoperative cognitive dysfunction.

BACKGROUND The objective of this prospective study is to determine cognitive dysfunction after thoracic surgery. METHODS Seventy-six patients undergoing thoracic surgery with single-lung ventilation (SLV) of an expected duration of >45 min were enrolled. Monitoring consisted of standard clinical parameters and absolute oximetry (S(ct)O(2)). The Mini-Mental State Exam (MMSE) test was used to a...

Cerebral tissue oxygen saturation during arthroscopic shoulder surgery in the beach chair and lateral decubitus position.

Arthroscopic shoulder surgery is a common procedure and can be performed with the patient in the lateral decubitus position (LDP) or beach chair position (BCP). Although the BCP is associated with better visualization and less bleeding, it has also been associated with hemodynamic changes and consequently cerebral hypoperfusion. Devastating events reported after surgery in the BCP were attribut...

Cerebral Oxygenation during Laparoscopic Surgery: Jugular Bulb versus Regional Cerebral Oxygen Saturation

PURPOSE We hypothesized that regional cerebral oxygen saturation (rSO2) could replace jugular bulb oxygen saturation (SjvO2) in the steep Trendelenburg position under pneumoperitoneum. Therefore, we evaluated the relationship between SjvO2 and rSO2 during laparoscopic surgery. MATERIALS AND METHODS After induction of anesthesia, mechanical ventilation was controlled to increase PaCO2 from 35 ...

Lateral positioning for regional analgesia during labour.

Sir,—We were interested to read the editorial by Peek and Firmin1 arguing for the greater use of extracorporeal membrane oxygenation (ECMO) in the management of severe acute lung injury. Their results in Leicester seem impressive (although apparently unpublished elsewhere) and the authors issue a challenge to other units to match their 34% hospital survival rate in a similar group of patients. ...
