Cerebral Desaturation and Postoperative Dysfunction After Thoracic Surgery

Cerebral Desaturation During One Lung-ventilation and Postoperative Dysfunction Afterthoracic Surgery: a Prospective Observational Study

The purpose of this study prospective observational study is to determine cognitive dysfunction incidence after thoracic surgery. We also evaluate evaluate the role of cerebral oxygen desaturations and hypertension as risk factors for post-operative cognitive dysfunction (POCD) in patients undergoing lung resection.

Inclusion Criteria:

• patients scheduled for elective lobectomy or wedge resection via thoracotomy
• one lung ventilation (OLV duration) ≥ 45 min

Exclusion Criteria:

• previous cerebral disease,
• dementia,
• severe cognitive dysfunction
• emergency surgery
• pregnancy
• patient refusal to give consent
• inability to give consent
• age ≤18 years
• ASA ≥ IV.
