Vets at British Zoo needed to give emergency resuscitation to a baby western lowland gorilla born after a very rare emergency caesarean.
The 11-day-old infant, a girl, was delivered after her mother showed symptoms of potentially life-threatening pre-eclampsia.
The baby, which is yet to be named, was born at Bristol Zoo Gardens weighing just over a kilo (2lbs 10oz).
She needed help from vets before she was able to breathe independently but is now doing well and is being hand-reared round the clock by a small team of experienced gorilla keepers.
The baby’s mother, Kera, is recovering and is being monitored closely by keepers and the in-house veterinary team.
It is the first time a gorilla has been born by caesarean at Bristol Zoo and one of only a handful of instances of it occurring worldwide.
John Partridge, senior curator of animals, said the baby gorilla – whose father is Komale – was not yet on show to the public.
“The birth of any gorilla is a rare and exciting event but the birth of a baby gorilla by caesarean section is even more unusual,” he said.
“It wasn’t a decision that we took lightly – Kera was becoming quite poorly and we needed to act fast in order to give the best possible treatment to mother and baby and to avoid the possibility of losing the baby.”
After being assessed by Bristol Zoo’s team of in-house vets, expert treatment was provided by Professor David Cahill, a professor in reproductive medicine and medical education at Bristol University and gynaecologist at St Michael’s Hospital.
Despite having delivered hundreds of babies by caesarean in his career, this was the first time Prof Cahill had delivered a baby gorilla by this procedure.
“Having been involved with the care of these gorillas over the years, with some trepidation and excitement, we were invited to the zoo to assess the wellbeing of Kera, because she was in late pregnancy and showed some signs of being unwell,” he said.
“Following our assessment, we considered that Kera might have pre-eclampsia, a condition that humans get, and that the only way to treat it was by delivery.
“We also thought that the baby in her uterus was showing signs of being very unwell and in need of delivery.
“My colleague from St Michael’s Hospital, Dr Aamna Ali, and I prepared for this extraordinary caesarean section and delivered a little girl gorilla.”
Prof Cahill added: “Along with having my own children, this is probably one of the biggest achievements of my life and something I will certainly never forget.
“I have since been back to visit Kera and the baby gorilla, it was wonderful to see them both doing so well.”
Rowena Killick, a vet at the zoo, assisted with the procedure and the immediate treatment of the baby, including performing emergency resuscitation.
“This was a very challenging operation and we are immensely grateful for the expert help we received which meant we were able to give care at the very highest level,” she said.
“The baby needed some intensive care immediately after birth and it is still very early days, but we are cautiously optimistic and will be keeping a very close eye on both her and Kera.”
