Short Time Low PEEP Challenge and Mini Fluid Challenge

Ability of Short Time Low PEEP Challenge and Mini Fluid Challenge to Predict Fluid Responsiveness During Pancreaticoduodenectomy

Optimizing fluid therapy is one of the main concerns for anesthesiologists during the intraoperative period. It becomes even more important in high-risk long lasting surgeries as pancreaticoduodenectomy. Therefore evaluating fluid responsiveness prior to fluid loading is highly recommended. To the best of our knowledge there is no study comparing the abilities short time low PEEP challenge and mini fluid challenge in predicting fluid responsiveness.
