Kolkata: Veteran actor Soumitra Chatterjee was given a blood transfusion on Sunday after his haemoglobin count fluctuated, one of the attending doctors said in a statement. His condition remained critical.The 85-year-old Chatterjee was admitted to a private hospital in the city nearly a month back after he had tested positive for COVID-19. The condition of the veteran actor was a matter of concern due to co-morbidities and advanced age, the doctor said, adding “We are fire fighting with complications happening.”“His bleeding part is not contained or controlled fully (and) his haemoglobin is fluctuating. We had to transfuse four units of blood (and) do a CT to find out his exact internal bleeding location. We are trying to seal the bleeding spot which is yet to be fully successful,” he said.“Every passing day we may be losing ground due to his advanced age,” the doctor said, adding that, “We are correcting a lot of things, we are optimising (his) organ functions, his neurological issues (have) not been treated fully to the point of his recovery. This is actually the main problem of Chatterjee’s general non-improvement of consciousness status.”However, the doctor added that “(Chatterjee’s) organ functions are holding on, his urine output and oxygen part is satisfactory,” insisting that they are are not losing hope despite, “so many things happening (to) an 85 year old.”The doctor said in the afternoon bulletin that they were considering to give him another dialysis, which would be the third one since last Wednesday. This was due to the bleeding which caused some “mild physiological alterations” as the doctor claimed.The other vital parameters of the thespian are working fine, he said, adding that “lung-wise he is doing okay and (the) infection part is not that bad.” Two sessions of dialysis had earlier been conducted on Chatterjee because of which his vital parameters became stable at that time.The veteran actor is on ventilator support since last week.The iconic actor, who had debuted in Satyajit Ray masterpiece Apur Sansar, is under treatment since October 6 after he tested COVID-19 positive. He later tested negative for the infection but COVID- 19 encephalopathy set in and various other comorbidity complications surfaced.
