The Plaintiff's Development
11On 3 November 2006, Dr Swapnil Shah, the neonatal Fellow at the Newborn Care Centre at Royal Hospital for Women, reported on the plaintiff.
12He said that, upon admission to the Neonatal Intensive Care Unit, the plaintiff was in respiratory distress, which was addressed by intubation. He said that the plaintiff was noted to have "...tonic posturing, which was followed by refractory generalised tonic clonic seizures". These seizures were treated by a mixture of drugs for the first three days.
13On the day after his birth, an electroencephalogram showed that the plaintiff was "... severely encephalopathic with diffuse cerebral inactivity". On the following day, a repeat EEG showed "... burst suppression pattern with electrographic seizures consistent with global encephalopathy".
14A later MRI of the plaintiff's brain showed a pattern of diffuse hypoxic injury with cortical and sub-cortical signal abnormalities. Upon discharge in late November, a neurological assessment of the plaintiff showed abnormalities including decreased movements of right upper limb and axial hypotonia.
15The plaintiff was reviewed by Dr Ian Andrews, a paediatric neurologist, when he was three months old. Dr Andrews' impression was recorded in these terms:
"Will had a pretty rocky start, but has made good progress. I suspect he will face neurologic issues relating to the HIE [hypoxic ischaemic encephalopathy] but so far he has done extremely well. ...
The right Erb's palsy has made good progress, and I expect it will continue to progress well and does not need any specific treatment."
16At six months of age, the plaintiff was a reviewed at the Growth & Development Clinic at Royal Hospital for Women by Dr Lee Sutton. Dr Sutton noted this:
"He is still breastfeeding, and has just started solids. He is managing the solids well. He is having speech therapy, physiotherapy and occupational therapy at the Spastic Centre at Ryde, and they are pleased with his progress. ... Will has had no fits since the neonatal period. Will has a splint for his right hand."
17He recorded his impression in these terms:
"Will is progressing with his fine and gross motor skills. It was nice to see him so vocal. He is appropriately placed, receiving therapy at the Spastic Centre."
18When the plaintiff was about 13 months old, he was again seen by Dr Andrews, the paediatric neurologist. Dr Andrews recorded his observations and conclusions in the following way:
"He is now 13 months old. As you know, he experienced hypoxic ischaemic encephalopathy and right Erb's palsy in the perinatal period. The sequelae include cerebral palsy, microcephaly, language delay and residual right arm lower motor problems.
There is a marked asymmetry between the right and left arm. He has antigravity movement at his right elbow, but his hand is largely held fisted with the thumb adducted. He picks up objects with his left hand and will bring them to the midline, but does not do this with his right.
...
Impression:
Will has a static encephalopathy with microcephaly related to his HIE. It is expected that development will slowly progress, however there will be significant issues, both cognitively and motor, which are expected to continue. ...
In addition, Will has reduced function of his right arm. This is like a combination of both lower and upper motor unit function. ..."
19In 2008, at the Oral Health Services Centre at Westmead, it was noted that the plaintiff presented with low facial muscle tone resulting in drooling due to open mouth posture. It was noted that the plaintiff appeared to have delayed development of his feeding skills, and was showing an emerging pattern of solid food management. It was also noted that he presented with clinical signs that might indicate a poor swallow function and possible aspiration.
20In April 2008, the plaintiff was reviewed by Dr Waugh, a senior staff specialist in paediatric rehabilitation medicine at The Childrens' Hospital at Westmead. Dr Waugh gave this summary of the plaintiff's development:
"Will has general low tone with mild dystonia of his right arm, and adduction of his right thumb. Will has no dynamic catch and normal joint ranges throughout. We explained that in HIE, difficulties with tone and motor movement control may only present at a later age, and Will needs to be monitored for this. ... Will shows some excellent non-verbal communication, but given his motor difficulties, it would be difficult to formally assess him. At around 4 or 5 years of age, when he has more reliable communication, his cognitive ability will be easier to assess. ... Will needs no specific intervention at this current time apart from the therapy he is receiving, but he does need hip surveillance."
21The plaintiff also came under the care and supervision of Dr Jayne Antony, a paediatric neurologist.
22In a report of 19 January 2009, Dr Antony recorded this:
"Despite the worrisome microcephaly and other adverse factors to suggest hypoxic damage, he was quite alert, aware and very motivated. It was my impression that he probably had some acute upon chronic hypoxic ischemic brain injury, rather than just an acute hypoxic injury towards to the end of the labour. His MRI scan reports also indicated that it was more likely to involve a chronic hypoxic ischemic injury, rather than just an acute hypoxic brain injury.
...
He had an MRI scan of the head on 20.11.08. That showed atrophy and high signal changes in the parasaggital and occipital regions, as well as both motor cortex regions, more marked on the left. There was mild atrophy of the thalami and wedge-shaped atrophy of the left cerebella hemisphere with subtle changes on the right. The left hemisphere was smaller than the right. The angiogram was normal, showing no evidence of abnormal cerebral circulation. The conclusion was that the scan was consistent with hypoxic injury in the newborn period."
23Dr Antony saw the plaintiff again on 22 June 2009, and reported on the following day that overall he was progressing well, especially with his communication. He was not able to pull himself up to stand, nor to walk. Dr Antony suspected that the plaintiff's head circumference was not increasing, but noted that it was not decreasing. She observed that he was being well cared for, and his management was appropriate.
