There was discussion about organ donation in the Anne Heche thread and I offered to share my experiences and it was suggested that a new thread might be more appropriate.
Anne Heche: Actress, lost soul, burn victim [Update: She has passed] - Cafe Society - Straight Dope Message Board
Now, currently I work in ER, so I send pts to ICU and occasionally hear that they became donors. In the past I worked in ICU and cared for pts that had the potential to become donors but didn’t, and others that did, and, once, I accompanied a pt I’d taken care of for a couple of days into OR and watched the procedure. I never specialized in donor care, and it’s been a while since I worked there, so I’m going from memory and older protocols, anyone is welcome to fight my ignorance.
Since there are a lot of variations, I thought I’d stick to the questions that came up in the other thread, at least for a start. I also have some ‘interesting’ stories regarding children for this topic which I can spoiler or just leave out depending on interest.
So, regarding time of death, we were always encouraged to state, died, in the past tense, whether a pt still has a pulse or not, when brain death is involved. Sometimes we would keep the machines going for an afternoon or a day to allow closure for families, or several days to make organ donation arrangements, but it’s easy for people to imagine hope where there is none, so we tried to be clear. Various news sources have used different times in this case, but I don’t know if that’s just casual research or they have editorial requirements for them. A pt has to be dead to donate, and it takes some time from getting the green light to donate and arrangements being complete.
When we had a potential candidate, we would contact a donor facilitation group and they would dispatch a nurse to our hospital. We always knew when they were in the house, and I believe that was intentional, because they always brought snacks and they always brought the same stuff. You’d walk into the breakroom and know what was in play out on the floor, and I was grateful for that. At first, they’d be in the wings, getting some information and monitoring the situation with little direct input, this can last for several days.
Once they got a green light, a flurry of activity would ensue. Primary responsibility would be transferred from the ICU doc to the transplant doc. We would draw labs to test for various diseases, HIV, Hepatitis, I’m not sure what else, and they run the histocompatibility markers, and send the results out to find the recipients. They’d have to confirm the recipients were still eligible and get them into their own hospitals. There may be 3 or 4 recipients getting the major organs and they could all be in different places and need different prep times, all while trying to minimize the time the organ is out of a body and not being perfused.
Unlike a gunshot wound or baseball bat where there is localized trauma, an anoxic brain injury (such as drowning or smoke inhalation) or a diffuse axonal injury (shearing or twisting) there is not. A CT scan 90 min after the event may not show much. So, the pt is monitored for a period of time, typically 4 days, and repeat imaging may show significant bleeding and swelling. During this time the pt may require a little sedation or a lot. Now, if they start waking up, well and good, but the drive to control your own breathing and keep foreign bodies out of your airway goes way back down into the lizard part of your brainstem which probably hasn’t changed much since the KT event, so if they’re passively tolerating the ventilator without sedation it’s considered an ominous sign, even if we still have to wait out the 4 days. IIRC, it was on the 5th day that Heche’s reps started saying things like profound brain injury, and not expected to survive.
In the Heche case, one of the questions was about the terms coma and medically induced coma. To external appearances, a person on sedating and paralyzing drugs may look the same as someone with a profound brain injury, but one is in a coma and one is in a medically induced coma. Having said that, I never hear medical people using the term medically induced coma, we just talk about sedation requirements.
