Perioperative assessment of patients with obstructive sleep apnea

Research in our group revolves around perioperative assessment of patients with obstructive sleep apnea, with focus on pathophysiological mechanisms behind intermittent hypoxia and drugs used in anesthesia.

Patients with obstructive sleep apnea (OSA) have repeated episodes with hypoxia during sleep leading to hypertension and cardiovascular morbidities. Among patients at risk for complications after surgery, OSA has been identified as one of the most important risk factors.

The overall aim with this translational project is to describe respiratory control in OSA from bed to bench in relation to effects of anesthetic drugs, and to evaluate the effect of continuous positive airway pressure treatment and postoperative risk-assessment and outcome in these high-risk patients. We will use a combination of epidemiology, advanced physiological monitoring of patients combined with modern molecular and imaging techniques.
