The family of a patient has lodged a case of medical negligence against Columbia Asia Hospital in Kolkata alleging that the hospital staff infused blood of a wrong group while performing a surgery.

The case has been filed in Kolkata’s Bidhan Nagar police station. The patient was taken to hospital after she complained of abdominal pain. Thereafter, she underwent a surgery on June 5. The woman is now battling for her life and is on the ventilator as post operation instead of A+ blood - which is her blood group - the hospital allegedly transfused AB+ into her body. Following which she suffered multiple organ failures.

"I admitted my wife to Columbia Asia hospital on June 5. She was infused blood of a wrong group during surgery. Her lungs and kidneys are damaged. Administration is now threatening to stop treatment if I refuse to pay the bills. I have already paid Rs 2.5 lakh," the woman's husband has said. He has also sent a letter to West Bengal Chief Minister Mamata Banerjee asking her to take strict actions against the hospital authorities.
