Unconsciousness

Hello, the situation is as follows: My grandmother is 86 years old and in good health.
She can cook, do laundry, and climb stairs by herself.
Last Friday, she experienced some chest pain and went to the Tzu Chi Hospital in Xindian.
The doctor informed us that she needed to undergo a coronary artery bypass graft surgery and assessed that my grandmother did not have high blood pressure or any other kidney issues.
Her heart function was strong enough to proceed with the surgery, and the doctor confidently encouraged us to support her decision to have the operation.
He also mentioned that due to time constraints, the surgery needed to be done as soon as possible.
Therefore, we trusted the doctor's expertise and confidence, and the next day she was taken to the operating room.
The surgery lasted 12 hours.
After resting for a day post-surgery, my grandmother surprisingly did not regain consciousness.
The doctor then stated that there was an issue with blood flow and that they needed to investigate the cause.
Consequently, she underwent a second surgery on Sunday, which lasted another 6 hours.
Since then, she has not woken up.
Now, the doctor suggests that my grandmother may have suffered a stroke, indicating that there were previous signs and that there was a risk involved.
These comments were made after the fact, and we wonder if it is too late to address these concerns.
As a medical professional, he should have been aware of these risks beforehand, so why were we only informed after the events occurred?
I have also consulted with others and learned that the first surgery may have failed, resulting in a blood vessel not being sutured properly, which could have prevented blood from reaching the brain, leading to the stroke.
Now, she may become a vegetative state due to this oversight.
My grandmother was in good health, and now, because of this personal negligence, she is facing lifelong suffering, along with the regrets and grief of our family.
We hope you can help us.
We are extremely grateful.

Hello: Since I have not personally seen the patient, I cannot make a judgment.
It would be better to consult the attending physician.
Older patients undergoing surgery or cardiac catheterization have their own risks, including the possibility of stroke.
Further examination should be conducted for confirmation.
I apologize for not being able to assist more.

More Info

I'm truly sorry to hear about your grandmother's situation. It's understandable to feel overwhelmed and frustrated when faced with such a serious medical issue, especially when it involves a loved one. Let's break down the concerns regarding coma after heart surgery, the associated risks, and the responsibilities of medical professionals.

Understanding Coma After Heart Surgery
Coma is a state of prolonged unconsciousness that can occur after major surgeries, including heart surgeries. The risk of developing a coma post-surgery can be influenced by several factors, including the patient's age, pre-existing medical conditions, the complexity of the surgery, and the overall health of the patient prior to the operation.

In your grandmother's case, at 86 years old, she is considered a high-risk patient for any major surgery, even if she appeared to be healthy and active. Age alone can increase the likelihood of complications during and after surgery. Additionally, if there were any undiagnosed conditions, such as vascular issues or previous transient ischemic attacks (mini-strokes), these could contribute to post-operative complications.

Risks Associated with Heart Surgery
1. Neurological Risks: One of the significant risks of heart surgery is the potential for neurological complications, including stroke. This can occur due to emboli (blood clots) that may dislodge during surgery or due to inadequate blood flow to the brain. If your grandmother had any pre-existing vascular conditions, these could have heightened her risk.

2. Anesthesia Complications: The use of anesthesia can also pose risks, particularly in older adults. Anesthesia can affect blood flow and oxygen delivery to the brain, which may lead to cognitive issues or coma.

3. Surgical Complications: As you mentioned, if the first surgery did not go as planned, it could have resulted in complications that necessitated a second surgery. If there was a failure to properly repair blood vessels, this could indeed lead to inadequate blood flow to the brain, resulting in a stroke.

Responsibilities of Medical Professionals
Medical professionals have a duty to inform patients and their families about the risks associated with any surgical procedure. This includes discussing potential complications, especially in high-risk patients like your grandmother.
1. Informed Consent: Before any surgery, patients (or their families) should be provided with comprehensive information about the procedure, including risks and benefits. This process is known as informed consent. If there were any indications that your grandmother had a higher risk of complications, this should have been communicated clearly.

2. Post-Operative Monitoring: After surgery, patients should be closely monitored for any signs of complications. If your grandmother was not waking up as expected, the medical team should have investigated this promptly and communicated their findings to you.

3. Transparency: If complications arise, it is the responsibility of the medical team to be transparent about what happened. While it can be difficult to accept, sometimes complications occur that are not due to negligence but rather inherent risks of surgery.

Moving Forward
It’s essential to have open communication with the medical team caring for your grandmother. Ask them to explain the situation in detail, including what they believe caused her current condition and what steps they are taking to address it. If you feel that there has been a lack of communication or transparency, consider seeking a second opinion or discussing your concerns with a patient advocate within the hospital.

Lastly, it's crucial to take care of your emotional well-being during this challenging time. Seeking support from friends, family, or professional counselors can help you navigate the complex feelings that arise in such situations.

I hope this information provides some clarity and helps you advocate for your grandmother's care.
