New Delhi, Feb 10 (PTI): The condition of Lance Naik Hanumanthappa Koppad of 19 Madras regiment has deteriorated despite aggressive therapy and supportive care, says the latest medical bulletin.

Hanamanthappa had been rescued alive six days after being buried under tonnes of ice in Siachen Glacier.

"He continues to battle the odds and his medical condition remains very critical," an earlier medical bulletin issued by Army Research and Referral Hospital here had said.

Hanamanthappa remains ventilator-dependent since arrival in the hospital yesterday, it said. The medical team at R&R Hospital is monitoring his situation continuously and is treating him with best expertise and resources available in the world, the bulletin said.

The hospital has said he is expected to have a stormy course in the "next 24 hours" due to the complications caused by re-warming and establishment of blood flow to the cold parts of the body.

Hanamanthappa was flown out by a helicopter yesterday from the site of the avalanche that hit his post at Siachen Glacier along with a medical specialist to the base camp at the glacier, from where he was brought to the Thois air base.

He was then transferred to Delhi by a fixed-wing aircraft of IAF along with a critical care specialist of the force and a medical specialist from the base camp.

Hanamanthappa is being treated by a team of intensivists, neurologist, nephrologist, endocrinologist and surgeons. He has been administered fluids, drugs to bring up his blood pressure, besides antibiotics.
