How do you assess your patient's intraoperative volume status? Are you using CVP or PCWP? What tools are you using to assess whether your patient in responsive to a volume challenge,( i.e. increase in stroke volume)? Are you using a change in CVP? Do you use a conservative vs liberal volume replacement model? How do you feel that this affects patient outcome? I would like to hear everyone's opinions and techniques and will follow with some current literature on the topic. BRING IT!
