Dr. George Nicolaou

nicolaou-gAssociate Professor
Director of City-Wide Clinical Services, Anesthesia
Director, Thoracic and Vascular Anesthesia


Dr. Nicolaou completed Medical School at the University of Witwatersrand, Johannesburg, South Africa and an Anesthesiology Residency Program at the University of Manitoba, Winnipeg, MB. He followed this with a Clinical and Research Fellowship in Thoracic and Vascular Anesthesia with Acute Pain Management at Western University and then started working at London Health Sciences Centre and St. Joseph’s Health Care.

He is currently the Director and Fellowship/Resident Coordinator of Thoracic and Vascular Anesthesia at London Health Sciences Centre.

Current Endeavors

1) Contributed to the development of an advanced VATS surgery and anesthesia workshop using a pig model at Western University;

2) In April 2013, Dr. Nicolaou was part of a multidisciplinary team that planned the layout of the hybrid vascular operating room. This hybrid suite is equipped with integrated patient imaging and numerous large, high-definition, flat-screen monitors for viewing images as well as the patient’s vital signs. This new operating suite has been an integral part of the hospital’s endovascular program.

3) Dr. Nicolaou is a member of a multidisciplinary team that has developed the endovascular program for the perioperative management of thoracoabdominal aneurysms.

Current Research

Dr. Nicolaou’s current research interests include lung protection strategies in one lung ventilation and spinal cord protection strategies in thoracic aortic surgery and in trauma patients.

Dr. Nicolaou is currenting researching

  • The influence of Continuous Positive Airway Pressure (CPAP) and Positive End-Expiratory Pressure (PEEP) with a Recruitment Maneuver (RM) on the Partial Pressure of Arterial Oxygen (PaO2) during One Lung Ventilation (OLV), employing a lung protective ventilation strategy;
  • Comparing Transcutaneous to Transdural Near-Infrared Spectroscopy for Detection of Regional Spinal Cord Ischemia in a Porcine model;
  • Biochemical markers of spinal cord ischemia in patients with acute traumatic spinal cord injuries;
  • The role curcumin in the prevention or renal failure in patients undergoing abdominal aortic aneurysm repair;
  • Endovascular repair of the thoracic aorta vs open surgery across morphologic subgroups: a meta-analysis of controlled studies.
