A Sydney hospital at the centre of a disastrous gas mix up has confirmed another newborn baby was affected by a loss of oxygen in 2014.

New South Wales health authorities have confirmed an oxygen supply cut out while being used to resuscitate a baby at Bankstown-Lidcombe Hospital.

The hospital said the baby survived the incident.

“In January 2014 a baby was delivered in the birthing unit at Bankstown-Lidcombe Hospital who required resuscitation,” the hospital said in a statement.

“During resuscitation the oxygen cylinder emptied and staff transferred the baby to the Special Care Nursery to ensure ongoing oxygen supply for the resuscitation.”

The statement said the incident prompted the installation of constant oxygen supplies in the hospital’s birthing unit.

“Following an investigation into the birth, the hospital installed outlets in the birthing unit that provided a constant oxygen supply,” it said.

“Last week, the hospital also tested gas outlets in the birthing unit and confirmed the presence of oxygen from all outlets.

“The birthing unit is separate to the operating theatre complex.”

Ms Skinner has defended her handling of the matter and rejected the State Opposition’s calls for her resignation.

State Opposition calls for parliamentary inquiry

Opposition health spokesman Walt Secord said he would be moving to set up an Upper House inquiry into the incidents as soon as Parliament returned from its winter break.

Mr Secord said the investigation Ms Skinner announced was inadequate and she had so far refused Labor’s calls to set up an external probe into the matter.

“We need this inquiry, the Baird Government and its Health Minister are stalling and any information that comes out is only coming out because of the media or members of the public coming forward,” Mr Secord said.

“This will compel witnesses to come forward and give evidence.”

He said he was trying to secure the support of crossbenchers to set up the inquiry.

Mr Secord also said the revelations added weight to the case for the Minister’s dismissal.

“The case to remove Ms Skinner builds every day.

“We only get information in the community when the media gets onto an issue involving Mrs Skinner.”

Meanwhile, the family of the baby who died have said the hospital’s error involving their baby was shocking.
