The Society of Thoracic Surgeons Task Force on Resuscitation After Cardiac Surgery provides this professional society perspective on resuscitation in patients who arrest after cardiac surgery. This document was created using a multimodal methodology for evidence generation and includes information from existing guidelines, from the International Liaison Committee on Resuscitation, from our own structured literature reviews on issues particular to cardiac surgery, and from an international survey on resuscitation hosted by CTSNet. In gathering evidence for this consensus paper, searches were conducted using the MEDLINE keywords "cardiac surgery," "resuscitation," "guideline," "thoracic surgery," "cardiac arrest," and "cardiac massage." Weight was given to clinical studies in humans, although some case studies, mannequin simulations of potential protocols, and animal models were also considered. ⋯ Finally, we recommend that full doses of epinephrine should not be routinely given owing to the danger of extreme hypertension if a reversible cause is rapidly resolved. Protocols are given for excluding reversible airway and breathing complications, for left ventricular assist device emergencies, for the nonsternotomy patient, and for safe emergency resternotomy. We believe that all cardiac units should have accredited policies and protocols in place to specifically address the resuscitation of patients who arrest after cardiac surgery.

Serial lactate measurements over time or lactate clearance has been reported to be clinically reliable for risk stratification in different pathologic conditions ranging from sepsis to trauma, but no data are so far available on the behavior of lactate during venovenous extracorporeal membrane oxygenation (VV-ECMO) support in refractory adult acute respiratory distress syndrome (ARDS). ⋯ Lactate (measured before ECMO initiation, as well as 6 and 24 hours after) is a prognostic factor in patients with refractory ARDS treated with VV-ECMO, and lactate clearance at 72 hours after ECMO initiation helps in the risk stratification of these patients, being independently associated with death.
