Ailing Marxist leader Jyoti Basu had a second blood transfusion on Wednesday and is responding to treatment though he is still critical and on ventilation in hospital.
"He is responding to treatment and medicines," Dr T S Kuckrejja, executive vice-president of AMRI hospital, where 95-year-old Basu was admitted on January 1 because of pneumonia, told reporters.
"His general condition still remains critical. He received a second unit of blood today. He continues to be on partial ventilation support," a medical bulletin issued by the hospital said in the evening.
Basu was given a unit of blood yesterday to raise his haemoglobin level, which had decreased to eight. It had risen to nine after yesterday's blood transfusion.
The CPI-M patriarch was given blood pressure stabilising drug, Ionotropes.
The medical board was constantly monitoring Basu's condition and would review it again at 11 am tomorrow.
"The markers of infection have marginally come down," D N Agarawal, executive director of the hospital said.
