Optimal fluid management of post-operative cardiac surgery patients is challenging. Dynamic hemodynamic responses to applied positive pressure ventilation may be predictive of fluid responsiveness.
Here, we report the hemodynamic effects of lung volume recruitment maneuvers (LVRs) in post-operative, paced cardiac surgery patients before and after the administration of an intravenous fluid bolus.
It was found LVRs may have negative hemodynamic consequences in post-operative cardiac surgery patients, and may compromise oxygen delivery while administration of an intravenous fluid bolus can attenuate these responses.
Hemodynamic responses to LVRs may be useful in predicting which patients may benefit from intravenous fluid loading post-operatively and these relationships are going to be further explored.
