Medical Malpractice is a cause of action held by a patient for negligence against a doctor. In it you have to prove that:
1) the doctor breached the standard of care that a objectively reasonable doctor would have provided under the circumstances;
2) the breach of duty caused the injury; and
3) the valuation of the damages.
Wrongful death is an action that is brought by the next of kin (spouse, child, or parent) to recover damages for the death caused by a third party by a tort
such as medical malpractice. In other words, it gives the family the right to bring the malpractice suit on behalf of the deceased. Thus, in this case, you must show that you have standing under the wrongful death statute in your state and you must then prove medical malpractice as the cause of the death.
The factors you mention above could likely be a cause of malpractice which led to the death of your loved one. However, to know for sure you will need to contact an attorney to review the medical records in your case. The attorney will closely inspect the records and if he/she thinks you have a case, they will hire a third party doctor to act as an expert witness to provide an expert opinion that the standard of care was breached by doctor and medical facility that treated the deceased patient.
