Hi Doctors, actually my mum had kidney problems, recently doctors said the phosphate level of my mum is very high, so have to operate to remove the phosphate. After the operation which is done 12.30pm afternoon, my mum seem to be ok, but around 9.30pm, my mum have difficulty to breath, according to doctor, the blood is clogged. So the doctor do a second operation to remove the clog blood. In the operation, doctor said my mum s heart stop function for estimated for 5 min. My mum in the ICU now, she is awake, i noticed that my mum cannot see anyone of us. Any problem with her eyes? She can recognize us, and her hand and legs also can move..just the visions problem. Can i know why is it so and any recovery can be done? My mum is 57 years old, and had undergo kidney dialysis for 8 years. My mum is around 1.60 in height and 55 kg in weight.
