A gorilla at the Philadelphia Zoo has given birth to a healthy baby after a difficult labor that required medical techniques typically used for delivering humans.

A keeper noticed 17-year-old Kira had gone into labor on Thursday. Gorilla labor is typically very quick, but by Friday, it had not progressed and she seemed unwell.

Concerned about the health of Kira and her baby, the zoo brought in a team comprised of both veterinarians and doctors more accustomed to treating humans – with incredible results.

Kira, a 17-year-old gorilla, went into labor on Thursday – but by Friday her baby had still not come and she seemed ill. Gorilla births are usually quick, so Philadelphia Zoo was concerned

They brought in a team of experts to help – and they weren’t just veterinarians. Because human and gorilla physiology is very similar, doctors who usually deal with humans were also hired

Kira had to be placed under general anesthetic while the doctors worked on her. She had an assisted vaginal birth – which is unusual for gorillas, and needed human ob/gyn help

The team included an ob/gyn, surgeons and anesthesiologists from hospitals affiliated with the University of Pennsylvania and Thomas Jefferson University, as well as University of Pennsylvania School of Veterinary Medicine.

A similar team was in place for a gorilla birth at the zoo last year, but the emergency response wasn’t needed.

After one-and-a-half hours, the team delivered the male baby using forceps and an episiotomy, a procedure to enlarge the birth opening.

‘It was an anxious and dramatic day at the zoo, but in the end a tremendously rewarding one,’ said Andy Baker, the zoo’s chief operating officer.
