Thiruvananthapuram | A team of government doctors has examined former Kerala Chief Minister V S Achuthanandan and reviewed his treatment at the private hospital where he has been admitted following a cardiac attack.

A seven-member specialist team from the Government Medical College here visited the hospital and examined the treatment being given to the veteran leader, the latest medical bulletin said on Tuesday.

The government doctors visited Achuthanandan as per the special instructions by the government, it said.

"The condition of Achuthanandan continues to be critical," the bulletin said.

The ventilator support, CRRT, and antibiotics currently being administered to the leader will be continued, with adjustments made as necessary.

Meanwhile, CPI(M) general secretary M A Baby, who visited Achuthanandan at the hospital in the morning, said the veteran is responding positively to the medicines.

The 101-year-old leader was admitted to the hospital last week and is being treated in the intensive care unit by a team of specialist doctors. His various health parameters are being closely monitored, sources added.

Achuthanandan, a towering figure in Kerala politics, has been battling age-related health issues in recent years and has largely withdrawn from public life.

He is the last surviving member of the group that founded the Communist Party of India (Marxist) in 1964, following the vertical split in the undivided Communist Party.

A lifelong campaigner for social justice and workers' rights, Achuthanandan served as Kerala's Chief Minister from 2006 to 2011.
