For those who don't want to click the link, here are the results:
"During the 42-month study period, a total of 263 patients underwent EDT. Return of a pulse was achieved in 85 patients (32.3%). Of those patients, 37 (43.5%) subsequently died in the operating room and 48 (56.5%) survived to the surgical intensive care unit. Overall, 5 patients (1.9%) survived to discharge and 11 patients (4.2%) became potential organ donors. Five of the 11 potential organ donors had sustained a blunt mechanism injury. Of the 11 potential organ donors, 8 did not donate: 4 families declined consent, 3 because of poor organ function, and 1 expired due to cardiopulmonary collapse. Eventually 11 organs (6 kidneys, 2 livers, 2 pancreases, and 1 small bowel) were harvested from 3 donors. Two of the 3 donors had sustained blunt injury and 1 penetrating mechanism of injury."
Keep in mind though, the OP's question is about any operative intervention to keep the trauma patient alive for potential donation. Many penetrating injuries requiring surgical intervention to the save the patient's life are far more survivable than injuries requiring an ED thoracotomy. So, a patient shot in the head and right common iliac artery can be kept alive with a simple laparotomy to control the abdominal bleeding (assuming the brain injury leads to brain death but not cardiopulmonary collapse).
