One of the separated conjoined twins, Kalia's health condition turned critical and he was put on ventilator support, a senior doctor of the SCB Medical College and Hospital in Cuttack said on Friday.
Kalia was put on ventilator support on Thursday night.
"Kalia is suffering from a chest infection. He has been put on ventilator support as his health condition is critical now," CBK Mohanty, the superintendent of SCBMCH, said.
Mohanty, however, said Kalia's twin brother Jaga was doing well.
The twins hailing from Milipada village of Kandhamal district had returned to Odisha on September 7 and have been admitted to SCBMCH since then.
