Stroke Volume and Arterial Pressure Fluid Responsiveness in Patients With Elevated Stroke Volume Variation Undergoing Major Vascular Surgery: A Prospective Intervention Study
Authors' conclusion
The PPV and Edyn showed good accuracy for the prediction of MAP and SV responsiveness in patients with elevated SVV during vascular surgery.
Study context
- Population
- Patients with elevated stroke-volume variation (SVV) (≥13% for >30 seconds) during major vascular surgery, given 250 mL Ringer's lactate within 2 minutes125 fluid interventions
- Participants
- 19 patients
- Exposure
- PPV and Edyn added to SVV for prediction of mean arterial pressure (MAP) and stroke volume (SV) fluid responsiveness
- Outcome
- Prediction of MAP and SV responsiveness
