A comprehensive guideline on this was written by us with the Society of Thoracic Surgeons Task Force on Resuscitation After Cardiac Surgery. This 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 including 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.
