Incredible footage captures neurosurgeons using their mobile phones as torches while removing a tumour after the lights failed during a power cut.
The operation took place at Hospital Barros Luco Trudeau in San Miguel, Chile, and was later shared on Facebook where it has been viewed 412,000 times.
It was reported a 34-year-old patient was undergoing the brain surgery for a tumour when the video was filmed.
Health official Arturo Zuniga told local media the automatic system for the generators was not activated when a power cut hit the area.
He added: 'The generators do work, and if the power cuts again there will not be a problem.'
Mr Zuniga also explained the hospital facilities are in the process of being updated, but vowed to open an investigation into the incident to provide the patient's family with all the facts.
He said family members were informed of the incident after the operation was finished, and also credited hospital staff for working well under difficult conditions.
The patient's sister, Paulina, claimed that he had to undergo another operation several days later after suffering a haemorrhage, according to local media.
Reports said he is still being treated in the intensive care unit, with the team of neurosurgeons refusing to carry out any more operations until the minimum standards are guaranteed by the hospital.
Local media said the patient's family are planning on suing the hospital.
The investigation is ongoing.
