What you have said above, in much better detail is, why I think the first bag and second bag are the SAME! I do think she contaminated the first bag, the baby was in no doubt administered synthetic insulin, his blood sugar readings etc showed this. We can’t say oh perhaps that other nurse was the poisoner because it wouldn’t fit with what was happening to the baby prior to the tissuing of the line.The evidence seems to concede that a new giving set and a new bag - a stock bag - was started at 10am when the first line tissued. LL was gone by then, and I can't see that she could have poisoned a stock bag on the off chance because it was anticipated that the first, bespoke TPN bag would be in use for 48 hours, so it was only by sheer chance that a second bag was put up. The evidence suggests that the level of contamination was the same. I think what has happened is that he has presented a number of scenarios, which include:
1. first long line tissues, long line is changed but giving set reused with new bag, thus contaminating new stock bag
(Problem with this scenario - he also said the amount of insulin would have had to be the same, and that was calculated at 0.58ml/hour. That is not consistent with a trace contamination)
2. first long line tissues, new line, giving set and stock bag used.
(problem with this scenario - that can only mean the stock bag was also contaminated, and to the same concentration, yet the use of a stock bag had not been anticipated, and when the need for it arose, LL had already finished her shift so wouldn't have been there to contaminate it)
For me, neither scenario points to her, and if the second scenario is correct, far from pointing to her, it would exclude her.
The first bag was 100 percent contaminated. The bag not being changed when the line tissued is for me the most logical explanation out of the three (also this bag was tested). I do think they will have a job in proving this sadly and we are back to the whole scenario of sub-optimal care coupled with a murderer it seems.
