Hi there.
I'm sorry to hear what happened. Unfortunately, there can be events in the medical field that are really unexpected and have little explanation, and what happened to your father maybe no exception. Off hand, I can think of causes like an embolism (blood clot that lodges in the blood supply of the brain) or a transient arrhythmia (problem with the electrical conduction of the heart). However, these would have shown up in the scans and EKG respectively. For stroke patients, neuroprotective agents such as citicholine or piracetam can be given to prevent further brain damage, however I'm not sure if these drugs can be applied to your father's situation. I suggest you discuss this treatment option with your father's doctors, and I hope everything will eventually turn out OK. Regards and God bless.
Thank you very much for responding. I will ask the doctor about these drugs, and see if they can or can't be applied to him. Again, Thank you!
My father had suffered a stroke 4 years ago. do you think that do to the morphine, and antibiotics that were given to him after the surgery that, that might have caused the problem? and if so is there anything else that can be done?
