Intra-aortic balloon pumps (IABP) can enhance coronary perfusion and reduce afterload, while venoarterial extracorporeal membrane oxygenation (VA-ECMO) provides robust circulatory support. Peripheral lines may be used initially if central access is delayed, but the central route is preferred for definitive management.
A thorough medication history, including over-the-counter and herbal supplements, can clarify the toxicological picture. Central venous access is strongly recommended for the administration of concentrated calcium chloride to prevent tissue necrosis if extravasation occurs.
