Per report, patient had SBP in the 80s on arrival but was asymptomatic. Prior to start of any procedure (no reports of being given sedative medications), she became unresponsive. CPR was initiated and was found to be in asystole. She received 3 rounds of CPR with ROSC. CT head without acute abnormality. Chest XR showing mild vascular congestion and interstitial edema. Initial labs showing AKI, elevated liver enzymes, BNP >29,000, troponin 39, lactic acid of 11, INR of 6.6, PTT 62, APTT 87. UA with protein, nitrite, moderate blood. Urine culture ordered. Blood cultures ordered. In ED, patient was hypotensive requiring addition of vasopressors. Targeted temperature management was started. Ceftriaxone and flagyl started for possible urinary tract infection and aspiration. Patient with profound coagulopathy, INR increasing to 12.0 on arrival to the ICU. Two units FFP and vitamin K were given. Patient with escalating pressor requirements at this time so CT t/a/p was ordered showing multiple bilateral rib fractures, nondisplaced sternal fracture with small anterior mediastinal retrosternal hematoma, small right sided hemothorax, right chest wall hematoma, patchy bilateral airspace disease consistent with atelectasis/infiltrate/aspiration, diffuse GGO consistent with interstitial edema, enlarged pulmonary arteries consistent with pulmonary hypertension, cholelithiasis. FDP elevated and 2 units of cryoprecipitate given 3/16. Hemoglobin decreased to 5.9 3/17 with INR of 5.4. Two additional units of FFP and additional dose of vitamin K ordered. Two units RBCs ordered. CTA thorax and abdomen 3/17 re-confirmed hemothorax and chest wall hematoma but no active bleeding noted. CT bilateral LE showed no evidence of hematoma. Trauma consulted who recommended chest tube placement. Overnight 3/16-3/17, patient also noted to have seizure activity on EEG and patient loaded with Keppra. Head CT 3/17 negative for hemorrhage or other acute processes. Patient remained in status epilepticus 3/17am and additional Keppra load was given and neurology consulted. Received Praxbind for continued bleeding/coagulopathy. 3/17pm went into PEA arrest with 10 minutes of CPR with ROSC. Bronchoscopy following ROSC noted evidence of bleeding from multiple areas, clots removed. MRI brain showing diffuse anoxic brain injury. Propofol stopped 3/19am.   After goals of care discussion this morning, all first degree relatives (daughter and son) all in agreement to transition to comfort care measures.
