The organizing idea is a clock that starts when the patient arrives, where permissive hypotension protects the clot and the wrong decision made confidently is worse than none. It moves through the timeline the patient is actually on: restrictive transfusion, the balanced massive transfusion ratio and the calcium citrate chelates, anticoagulation reversal run in parallel rather than as a delay, and field-clearing erythromycin before endoscopy. It closes on the two recognition stems the boards reward, the herald bleed of an aortoenteric fistula and the two arteries where failed hemostasis sends you to interventional radiology.\n \nTopics covered\n\nUpper GI bleeding as a resuscitation problem\nRestrictive transfusion target and its exceptions\nMassive transfusion protocol and calcium repletion\nAnticoagulation reversal in the first hour\nPre-endoscopic erythromycin and why TXA fails\nAirway protection and endoscopy timing\nAortoenteric fistula recognition\nSalvage angiography for failed hemostasis\n \nKey decisions\n\nTransfuse to a restrictive hemoglobin trigger of seven with a target of seven to nine, raising the trigger to eight only in active acute coronary syndrome, and transfuse empirically in uncontrolled hemorrhage because the lab hemoglobin lags real-time loss by thirty to sixty minutes.\nActivate the massive transfusion protocol at anticipated need over ten units of red cells in twenty-four hours or four in one hour, delivering a balanced one-to-one-to-one ratio and repleting ionized calcium that citrate chelates.\nReverse warfarin with four-factor prothrombin complex concentrate rather than fresh frozen plasma, reverse dabigatran with idarucizumab five grams and apixaban or rivaroxaban with andexanet alfa, and run reversal in parallel with endoscopy rather than letting the INR delay it.\nGive erythromycin two hundred fifty milligrams...","thumbnail_url":"https://img.transistorcdn.com/-FuAdDBcPDLhEoUmroZKtOBRvuBn_FHPpYlh41hOnU4/rs:fill:0:0:1/w:400/h:400/q:60/mb:500000/aHR0cHM6Ly9pbWct/dXBsb2FkLXByb2R1/Y3Rpb24udHJhbnNp/c3Rvci5mbS9iNzlh/ZTU4Y2MzNWExMjQ5/MjA5OWMwMmI3ZTk5/NGFiZS5wbmc.webp","thumbnail_width":300,"thumbnail_height":300}
