Are there test the hospital can do to prove medically he is brain dead rather than 'likely' . I understand his parents didn't want a test originally because it would involve removing his ventilator for a short period , which would compromise his breathing ..
Hollie was claiming the original MRI wasn;t Archies due to a discrepancy in the number of teeth ??
Unfortunately by the time the doctors did try the brain stem death test, as ordered by the court, he was essentially too dead for it to be useful. One of the tests is a motor response test, and to fulfil the brain stem death criteria you need to not pull away from painful stimulus.
However, before this they did a preliminary test of peripheral motor (movement) nerves. Motor nerves need to work in order for muscles to move. In the ICU setting excessive sedation can cause blockage of peripheral nerve function so I suppose it was done to prove he wasn’t being sedated or paralysed. You can imagine a scenario where someone wants to move but can’t because they paralysed from anaesthetic drugs.
However, the test was done long long after any paralysing or sedating drugs would have left his system but there was no peripheral nerve response, which meant there was a theoretical possibility of Archie feeling pain and not being able to respond to it because his nerves couldn’t transmit the impulses to his muscles.
In reality he was just too dead, which is why his peripheral nerves didn’t respond.
If you read the High Court judgement you can see the results of his MRI scans, showing no blood flow to his brain and how his brain is necrotic and dropping off down his spine.
MRIs are done in slices, not all of his teeth would have been on the same plane/slice. Nothing sinister or unusual.
