Doctors at Fortis Escorts Heart Institute here successfully conducted a bypass surgery to revive a woman, who was nearly brain dead with no oxygen supply to the brain and "zero" blood pressure level for 10 minutes, the hospital said on Wednesday.
Saraswati Devi, who had undergone a stenting procedure a few months ago, began experiencing chest pains recently. She was diagnosed to have a worsened cardiac condition, which needed an urgent bypass procedure, said the hospital in a statement.
As doctors at Fortis Escorts Heart Institute were preparing for the surgery, the woman suffered a massive heart attack and her blood pressure level plummeted to zero and could not be revived even after 20 minutes of CPR (cardiopulmonary resuscitation).
However, the doctors hurriedly managed the surgery -- from sterilising the surgical site to opening up the chest cavity -- in 10 minutes during which the heart beat and blood pressure was zero and the oxygen supply to the organs was also completely cut off.
"We had to work fast as we needed to ensure that the brain does not go without oxygen supply for too long. Medically a person is declared brain dead if the oxygen has not reached the brain for four minutes. In this case, oxygen did not reach the brain for 10 minutes," said SN Khanna, Associate Director (Cardiac Surgery) at the hospital.
While the surgery was successful overall, the doctors feared that due to substantial lag in oxygen supply to her brain, the woman could suffer from severe brain impairment.
"We were extremely apprehensive about the condition the patient would be in when she woke up but there was no untoward damage to her brain functions. It was nothing short of a miracle," Mr Khanna said.
Saraswati Devi, 50, recovered well and was discharged from the hospital, the doctor said.
