We focus on monitoring and optimizing the cardiovascular system perioperatively with the aim to reduce adverse postoperative outcomes.

An estimated 4.2 million people die within the first 30 days after surgery each year.  (Nepogodiev D, Martin J, Biccard B, et al. Global burden of postoperative death. The Lancet 2019; 393: 401). Therefore our group focuses on monitoring and optimizing the cardiovascular system perioperatively.

Haemodynamic management is one of the main priorities of the anaesthesiologist, since haemodynamic instability is associated with adverse postoperative outcomes. Therefore, we aim to explore innovative methods of monitoring and optimising haemodynamic status, but also monitor oxygenation status at tissue level.

Our research areas are:

  • Haemodynamic monitoring 
  • Haemodynamic optimisation/goal directed (fluid) therapy
  • Microcirculation and tissue oxygenation

How our research benefits to society

The haemodynamic research group focuses on methods to monitor and optimise the cardiovascular system in the perioperative phase. It is known that for example hypotension is associated with acute kidney injury, myocardial injury, and mortality. By monitoring the function of the cardiovascular system closely, with innovative methods, we hope to detect and treat haemodynamic instability in an early stage with the aim to reduce postoperative adverse outcomes and decrease postoperative mortality.

  • Our research group has implemented a protocol for goal directed hemodynamic management for high-risk patients. This has been accompanied by several research projects on UMCG level as well as a large multicenter randomized controlled trial. Furthermore, our experience has been incorporated in the national modules on Perioperative Goal Directed Therapy of the Dutch Society of Anesthesiology (NVA) in collaboration with the Dutch Societies of Cardiology, Surgery, and Intensive Care.

  • Our research group aims to contribute to a reduction in intraoperative haemodynamic instability and therefore also a decrease in postoperative adverse outcomes.
