WATCH: Baby is born while still inside amniotic sac

Giving birth is one of the most natural phenomena of the female human body, but this one, caught on video, is a rare occurrence.

A baby was successfully delivered while still inside its fully intact amniotic sac, the fluid-filled sac inside the womb that contains and protects the fetus, in a hospital in Spain last week. The unusual case, estimated to occur once in every 80,000 births, was filmed by one of the hospital nurses, The Sun reported.

As seen in a one-minute-and-20-second clip, the baby was born with the membrane covering its entire body, just minutes after its twin was delivered normally. 

Doctors placed the newborn on a hospital table, as it curled up inside the clear sac, also known as caul, with a visible blue umbilical cord wrapped around its body.

After marvelling at the amazing sight, they carefully split the sac open and delicately removed the infant from its natural casing.

In most cases, the amniotic sac is broken during the strenuous process of childbirth, which is known as “water breaking,” while it is pierced with a scalpel during a cesarean birth.

Doctors and nurses, meanwhile, gathered around the table to catch a glimpse of what medical professionals consider  a once-in-a-lifetime opportunity.

Giselinha Correa, the nurse who filmed the birth process, said she was privileged to witness such a magical moment.

“It was magic. Exciting to all team!!! We were waiting to stabilize the first baby and the second came softly, in fact, look there that beautiful!!! Historic moment!!!!” the delighted nurse wrote on the YouTube video’s comment section.

Netizens, meanwhile, were left in awe, as the original video has been viewed 6.8 million times, just a day after it was posted.

A similar occurrence also happened in the same country a year ago, where another baby was born while inside its caul.  Khristian Ibarrola
