Friday October 14th 2022 - Live updates from the trial.
Day 1 of Evidence
10:32am
The case is now resuming. The jury of 12 is now filing into court.
[...]
11:45am
Medical expert Dr Dewi Evans is now being called to give evidence.
He has been named several times during the prosecution opening.
11:49am
Dr Dewi Evans is a consultant pediatrician. He is giving his background and experience.
The court hears he has specialist knowledge of new-born babies, in providing healthcare, including intensive care, in the 1980s and 1990s in Swansea.
11:54am
Dr Evans confirms he has never been employed at the Countess of Chester Hospital, nor has hae had any involvement with the care of babies involved in this case.
He said he was involved in the development of neonatal care.
"It was an essential and important part of our generation that we provided good services for these ill babies.
"A lot of my experience was not about reading books, but was hands-on. You were there, with a sick baby in the incubator. You support the monitoring - nothing as good as it is now. A lot of it was 'touch and go', really. It could be quite fraught as there were ther deamdns on children's services.
"We were passionate about these babies to get money for developments...and...publicity for baby care.
"In 1980 in Swansea, the health board built a brand new children's department with a new neonatal unit that I had designed.
"Life became easier as...we had some superb nursing staff and by that time there were far more junior doctors developing an interest in baby care."
11:55am
"Babies arrived in all sorts of conditions. The most common were associated with prematurity. One would have to see them through the first few days of life - giving them oxygen...CPAP - which has saved thousands of lives over the past few decades.
"If not CPAP, it would be intubation - a breathing tube into the lungs and put them on...a breathing machine.
"The initial machines were primitive...but they worked.
"In addition to giving babies ventilation support, we would give them IV fluids to help them absorb milk."
11:56am
Cannulas would also be used to help babies get adequate fluid, such as glucose and amino acids.
Sometimes a 'cocktail' of nutrition would be required for each baby.
11:58am
"All the neonatal units are dedicated units. They are responsible only for new-born babies.
"Usually they are next door to the maternity unit. They tend to be divided into sections - the sickest in the intensive care area, babies who are recovering are in a high dependency area, and babies who are recovering but too sick to go home are in the 'ordinary' area."
12:02pm
Dr Evans said he gave up his full-time medical practice in 2009 after 30 years. He has done a few short-term locums since then, but has since dedicated his time to the courts, providing reports for baby care.
He had done reports involving clinical negligence - the first in 1988. He said he does not take on new cases involving that now.
He now says he takes time in family courts and crown court, involving serious cases of babies having died suspiciously or being injured.
He has prepared reports for police authorities, such as the National Crime Agency.
He has also prepared reports on behalf of defendants.
12:09pm
The court is being reminded of the 'tiered' hospital structure locally, with Arrowe Park and Liverpool Women's Hospital designated as 'level three' units, able to provide the most complex neonatal care.
The Countess of Chester Hospital was designated as a 'level two' unit, able to provide intensive care for vulnerable babies up to 48 hours, after which they would be transferred to a level three unit.
Other hospitals in Cheshire, such as Leighton, were designated as 'level one'.
Alder Hey was the designated surgical hospital unit.
12:15pm
The court hears the Countess of Chester Hospital neonatal unit has four rooms - room 1 the ICU, room 2 the HDU, and rooms 3 and 4 the special care rooms.
Babies would be moved between the rooms as their condition changed, with transtitional care cots available.
Entry to the neonatal unit was controlled through locked doors. One from the public entrance side, the other from the maternity/labour side.
Swipe cards would be used by staff to gain access to the neonatal unit, and their dates and times would be recorded.
12:17pm
Times when this would not record someone would be:
a) when person A swipes to open the door, and person B also enters at the same time
b) from inside the hospital via a push-button to open the door
c) via the buzz system of gaining entry - pressing a buzzer and a member of staff would provide entry for individuals
The system of entry is 'commonplace', the court hears.
12:20pm
The court is now being shown a walk-through of the neonatal unit at the Countess of Chester Hospital, dated September 2021 - which has changed following hospital upgrades since 2016.
12:26pm
The 10-minute video is being played to the jury, showing all the rooms in the neonatal unit, and what purpose the rooms served back in 2016.
12:30pm
The court is hearing from a list of agreed facts - ie, evidence agreed by the prosecution and defence.
The hierarchy of the Countess of Chester Hospital staff is being explained to the court.
12:33pm
Doctors would be alerted by two forms of 'bleep' - one non-urgent, the other 'urgent' - the latter being labelled a 'crash call'.
12:37pm
The neonatal unit baby monitors, used to monitor vulnerable/unwell babies, are now being explained to the court.
Dr Evans says if levels fall below specified values, or if monitoring equipment falls off the baby, an alarm will go off to alert medical staff.
12:39pm
A video explaining the technicalities of the Phillips IntelliVue monitors is played to the court.
They are similar to monitors found for hospital patients, but the values are set to a 'neonatal profile', and cannot be changed.
Dr Evans explains the values for neonatal babies are different to children, and to adults. Values for neonatal babies would be "far too fast" for children.
12:41pm
A heart-rate of 140 is "fine" for a neonatal baby, but a sign of sickness for an adult.
Over oxygenation "can lead to blindness" so greater care should be taken for such babies.
12:44pm
Alarm parameter settings can be adjusted by a nurse, but must be in 'clincially safe' settings, the video explains.
For example, a heart rate range can be between 50bpm and 165bpm, with the alarm sounding if the heart rate goes outside that range.
12:46pm
Dr Evans explains the monitor also shows wavy lines which show how regular the heart rate is, and the pattern of breathing.
12:51pm
The video, played to the jury, demonstrates what alarms sound when a 'yellow alarm' goes off, and a 'red alarm'. The red alarm is for more immediate emergencies, and has a different tone to the yellow alarm sound.
12:53pm
The alarms can be 'paused', via the 'pause' button, which turns the alarm off for one minute.
12:53pm
A light will continue to show on the monitor, either yellow or red, depending on the type of alarm that sounded, even when paused.
12:58pm
The alarms can be manually turned off, the video explains, for each parameter.
If done so, a display on the monitor would show the alarm for that parameter had been turned off.
"This would not be standard practice," the court is told.
If the monitor numbers then headed outside the alarm parameters, the numbers on display would then start flashing.
2:14pm
Dr Dewi Evans is being asked about medical terms, such as 'air embolism', apnoea, blood gases, capilliary, and medical equipment.
2:16pm
A video is now being presented to the court showing what a cannula is, and a demonstration of how it is administered to a patient.
2:22pm
A video is now explaining what happens in 'neopuffing', more crudely known as 'bagging' of patients, "one of the most important pieces of equipment" in a neonatal unit, which can give artificial breaths to a baby.
2:23pm
There is a dial which can deliver varying amounts of oxygen, from 21% (air) to 100%.
The pressure can also be altered depending on the prematurity of the babies, "to help open their lungs".
2:24pm
The neopuff machines are checked "once each shift" by neonatal staff.
2:26pm
The video played to the court shows a demonstration of a neopuff machine, with the mask being attached to a dummy baby's nose and mouth.
2:27pm
'Five inflation breaths', each for three seconds at a time, are given to babies with breathing difficulties or for babies who have collapsed.
2:30pm
The neopuff machine can also be applied to intubated babies, as the video demonstrates.
A second video, titled 'neopuff consumables', is played to the court demonstrating additional equipment.
2:35pm
The process of getting 'aspirates' from the stomach, via a naso-gastric tube, is also explained to the court.
Dr Dewi Evans says it is important for the stomach to be empty, prior to a next feed for a baby, as the presence of milk aspirate could suggest problems with that child.
2:39pm
The video demonstrates that any aspirate found has a 0.5ml sample checked for pH levels.
Dr Evans explains the syringe used is purple in colour - it is a syringe only used for naso-gastric tube, and cannot be used for IV feeds - you cannot be used to inject milk into a vein, for example, as the shape is different.
2:44pm
The video played to the court says action can be taken by medical staff to withdraw air from the baby's tummy if the abdomen becomes distended.
Dr Evans says 'free drainage' means the naso-gastric tube (NGT) is left in the stomach, the other end is left open, so if any air is in the stomach, it can escape through the NGT.
2:52pm
The court is now hearing the definition of the term 'NEC', pronounced as 'neck' "in the business", a gastro-intestinal disease in the small intestine.
Dr Evans says the causes can be poor blood flow, as a result of infection. Sometimes it can appear "without being sure why".
"The sicker the baby, the greater the risk," Mr Evans tells the court.
Other symptoms are 'a bit' of abdominal distension, bile aspirates and blood in the stool. Early diagnosis is important to lower the need for surgery.
The prosecution says NEC will be referred to a lot in the course of the trial.
2:53pm
"Doctors, if they suspect NEC, start treatment immediately" - even if they are not 100 per cent sure of a diagnosis, Dr Evans adds.
2:55pm
One of the reasons for this is some of the babies may not "tolerate" surgery.
The court hears NEC is a "serious" medical emergency.
The prosecution says if symptoms are detected, they treat swiftly.
"And properly," Dr Evans adds.
2:58pm
Different types of rashes are discussed, in particular a purpuric rash where if you press on the skin, the rash does not fade.
It is associated with sepsis, or blood clotting, and is a "serious medical problem".
3:01pm
The process of intubation is demonstrated on a video presented to the court.
3:15pm
CPAP is the "least invasive form" of giving breathing support to babies, the court hears.
BiPAP is the next stage, and 'full ventilation' "requires a very sophisticated ventilator" and is the most invasive form.
A positive sign of "returning to normal" is for the oxygen saturation levels return to over 90%.
The respiratory rate is then controlled via the ventilator setting.
If the baby 'fights' against that, by trying to breathe independently, that baby is sedated so it can benefit the most from the ventilator.
3:22pm
A video is presented to the court displaying the process of CPAP, and what responsibilities nurses and doctors have while the equipment is attached.
The video says it is "inevitable" air will pass into the stomach and intestines, and with time, can lead to "distension of the stomach and intestines". To avoid this, an NGT is inserted into the stomach to help ventilate excess gases.
The video says "Despite this, some babies on CPAP will still develop some degree of CPAP belly."
Dr Evans says CPAP is the "safest method" as it is the "least invasive".
3:23pm
The video explains there are "other important causes of abdominal distension and it is the doctor's responsibility to distinguish CPAP belly from other conditons, particularly...NEC."
