Perioperative Fluid Therapy Optimization in Spinal Surgery

Perioperative Fluid Therapy Optimization in Spinal Surgery Using Non-invasive Measurement of Haemodynamics (ClearSight System, Edwards); a Comparison to Standard Method

The decision to give fluids perioperatively could be based on methods used to identify preload responsiveness, either invasive or noninvasive estimates of stroke volume variation during mechanical ventilation. This study compares fluid management using continuous noninvasive cardiac output measurement with standard perioperative fluid management.

The aim of the study is to optimise fluid managemet and to reduce perioperative risks during spinal procedures in prone position. Adequate perioperative management guided by hemodynamic monitoring can help to reduce the risk of complications and thus potentially improve outcomes.
