Given that six of the seven babies had post mortems, and baby E didn't but had been ascribed a cause of death, there's only one baby whose cause of death was unascertained at post mortem and that was baby A. I'm gonna guess that she was referring to baby A
At one stage in the WhatsApp and Facebook messages Letby mentions the possibility of an air embolism being the cause of a baby's death.
His collapse happened soon after shift handover and he'd died before 9pm.
In police interview she said (amongst other things) -
"She said Child A went pale after a colleague had connected the fluids. She said Child A had "gone pale" 'about five minutes' after the fluids were administered.
She said she could not recall who attached the fluids line, but believed it was her nursing colleague Melanie Taylor who had connected the fluids.
She agreed she had been taught to prime lines so air could not get in them.
She denied having done so via Child A's long line or UVC.
She said she didn't know exactly what an air embolism was."
Recap: Lucy Letby trial, Wednesday, October 26
The actual timing of events was -
8pm – Child A was said to be stable and care handed over by MT to LL at 8pm. Emergency equipment checks made.
8.05pm – Child A’s administration of fluids via the long line; '10% glucose commenced at 8.05pm', signed by Lucy Letby, as a 'major event' on the chart for the 8pm timeslot. LL’s barrister asserts that MT was in sterile clothing and administered these fluids with LL assisting. MT doesn’t recall. MT does not recall Child A being jittery (see LL’s retrospective nursing notes next morning for context) – says she would have made a note of it if she saw that.
MT’s retrospective nursing note (written at 9:28pm): "Observations stable, pink, well perfused. UVC still in situ, but in wrong position, to be used if no other access available. "Long line inserted by reg Dr Harkness, secured, x-rayed. 10% dextrose run through and connected to long line."
8.14 - 8.15pm & 8.18pm – MT is using the computer, referring to the family of A & B being updated on the condition of child B.
MT is unable to say how long she had been away from Child A’s incubator but thinks it was after the dextrose was administered. At some point Child A’s monitor sounded and she went over to help LL, once she realised he was deteriorating and wasn’t recovering. Her notes weren’t completed (she was called back the next day to complete them) because she became involved in getting adrenaline for Child A.
8.20pm – Child A hands and feet noted to be white in LL’s retrospective notes the next morning.
8.20pm – swipe data shows the shift leader entered the neonatal unit. She became involved in the resuscitation attempts. She describes the unusual skin colouring- which she’d never seen before.
C.8.24pm – Dr.DH was scrubbed and sterilised and concentrating on a procedure on a third baby in the room.
8.26pm – LL calls for help for Child A’s breathing problems. Dr.DH attended. Nurse CB was in Room 1. When Child B was safe, she went to help with Child A, helping LL with neopuffing. She said no crash call was put out as doctors were already in attendance.
