Brief Summary:
In 2019, the investigators initiated a new priming fluid therapy strategy in the cardiopulmonary bypass (CPB) machine for patients undergoing pulmonary endarterectomy surgery. It consisted in a transition from a "pure" primarly balanced crystalloid priming fluid strategy to a 4% human albumin priming fluid-strategy in addition to a low volume of balanced crystalloid solution. The rationale was the theoritical assumption that albumin leads to better intravascular volume expansion compared to crystalloid and therefore could reduce overall volume requirement during surgery and consequently potentially decrease the incidence of postoperative pulmonary complications. The objective of this propensity-matched study was to evaluate the effectiveness of this intervention
Detailed Description:
Intravenous fluid is usually needed (and sometime in important amount) to increase intravascular volume during cardiac surgery and to prime the cardiopulmonary bypass (CPB) circuit. In this context, albumin has been frequently used as the ideal fluid choice. Although albumin has the disadvantage to be much more expensive than crystalloids and not to be free from immunological reactions, this solution provides a more sustained volume effect that a similar volume of crystalloid which may result in smaller volumes of resuscitation fluid being administered. It also better preserves the on-bypass oncotic pressure and reduce extravascular lung water. These considerations are important especially during pulmonary thromboendarterectomy surgery (PTE), a high-risk procedure which aims to resect thromboembolic material. Reperfusion lung injury (RLI) and/or acute respiratory distress syndrome (ARDS), are the most encountered postoperative pulmonary complications and are significant risks factors of morbi-mortality. As data suggest that RLI and ARDS are high-permeability phenomenon, cautious is required to avoid fluid accumulation/overload during this complex procedure. In addition, this surgical procedure has a relatively high CPB duration which can induce a systemic inflammatory response syndrome, damage the endothelial glycocalyx and vascular barrier where crystalloids may extravagates and accumulates in the lungs. On the contrary, albumin solution used during the priming of CPB can favorably preserve oncotic pressure, have a protective effect on endothelial glycocalyx and better maintain vascular barrier competence, preventing interstitial edema and potential pulmonary complications.
In March 2019, the investigators initiated a new priming fluid policy strategy aiming at replacing our traditional pure crystalloid fluid administration for an albumin one in order to decrease the relatively high-rate of pulmonary complications observed in the investigators patients.
