CPI-M patriarch Jyoti Basu was put on haemodialysis on Thursday after further deterioration in his cardiac and renal functions, doctors attending on him said.
"The cardiovascular system has further deteriorated.
His cardiac and renal functions have undergone further deterioration and he has been put on haemodialysis since 6.30 pm," a medical bulletin quoted D N Agarwal, executive director of AMRI Hospital, where Basu was admitted on January one with pneumonia, as saying.
"After monitoring the haemodialysis for four hours to clear accumulated toxins in the blood, the doctors will be in
a position to say whether he is able to accept it," he said.
Haemodialysis is done to remove waste products from the blood by passing it out of the body, through a filtering
system (dialyser), and returning it to the body.
According to Agarwal, the 95-year-old leader's condition was very critical and his oxygen requirement has
further increased on ventilator support.
He was also requiring increased dose of blood pressure stabilising Ionotrops, he said.
Earlier, AMRI Hospital doctor Susruth Banerjee and Basu's personal physician A K Maity, both of whom are on the
medical board treating the former chief minister, said he was heading for multi-organ failure.
There was a also large mobilisation of police near the hospital.
