Maity said that the if his health permits, Basu will undergo two-hour haemodialysis for the second continuous day on Jan 15, after undergoing the first one on Thursday, Jan 14.
"The 95-year-old leader will also undergo a tracheotomy if his condition permits," Dr Maity.
He added that toxins in Basu's blood was considerably reversed after the dialysis on Thursday night, Jan 14, adding that his urine output, on the other hand, has decreased below the normal 40 ml to 10 ml per hour.
"There is neither any further improvement nor deterioration in his condition," he said.
Dr Susruth Banerjee, who is also a member of AMRI hospital along with Maity, confirmed Maity's observation on the chief minister's condition.
"If Basu is able to tolerate a two-hour dialysis again, another dialysis might be done in the evening. His condition is very critical with his heart being erratic and there has been deterioration in his senses," he said.
The former chief minister of West Bengal was admitted to AMRI hospital with pneumonia on Jan 1, 2010. He has been on ventilator support since Jan 6.
