Forgive me for being stupid, what was the situation with the brain stem testing (BST) that meant he couldn't be tested? I thought originally they didn't agree with it so the hospital had to gain permission to go ahead and do the testing, and then when they did the testing 'Archie failed on one area'. What did he fail and how? I'm not understanding that bit.
From my experience (sorry to keep referring to it, but it's so close which is why this case is interesting me) BST should take place >6 from the loss of the last brain stem reflex (so this could be a cough, triggering the ventilator, blinking, etc), electrolytes and vital signs must be within range (as much as able given the patients condition), and the patient should be clear of all sedative, muscle relaxing and opiate medications. BST is then undertaken by two senior clinicians and is done slowly, thoroughly and in numerous stages. And then repeated for clarity.
All of the cranial nerves are then tested. So light shone into pupils to test reactivity, ice water syringed into ears to test vestibulo-ocular reflex, gag and coughing tested, reaction to pain is tested with more pain then we would usually use in day to day/hourly assessments, doll's eyes response, and more. All sounds cruel but it is vital and necessary. And then the apnoea test is undertaken, which yes does mean coming off the ventilator for a short period of time, to see if they breath spontaneously, but is mostly about testing CO2. The patient is monitored throughout, pre-oxygenated beforehand and has a bagging circuit attached to their ETT/trachy so they can receive manual breaths if they become compromised.
Anyway, I've gone way off my question. Which bit is the poor boy said to have failed? I'm just curious, because if he 'failed' any of the BST then it may be his brain stem was marginally in tact at the time, but 'passing' 90% of the test is hardly a big win and paints a pretty grim picture - and by now, this many weeks on, I imagine what little he did have of his brain stem has been completely compressed and has gone?
