Brain; This study facilitate research on appropriately determining prognosis after cardiac arrest and to establish better treatments for recovering from brain injury, a working group composed of a Johns Hopkins Medicine physician and American Heart Association (AHA) experts have release a scientific statement that provides best practices on how to predict recovery in comatose survivors. The statement was release in the July 11 issue of Circulation.
At this time, there aren’t any rules or set criteria for how to carry out a study to predict recovery. Because of low quality, flawed research; so decisions relate to current policies; which may result in prediction errors that may forecast a poor outcome for patients who may have a good outcome, or vice versa. Moreover, the lack of standards for predicting outcomes has made it all; but impossible to properly study therapies that could potentially heal; so the brain and the rest of the body after being resuscitated from cardiac arrest.
The Brain Resuscitated
To develop this scientific statement, the AHA Emergency Cardiovascular Care Science Subcommittee form an international panel of experts in the adult and pediatric specialties of neurology, cardiology, emergency medicine, intensive care medicine and nursing. The group’s goal is for the clinical research community to develop an accurate; hence precise clinical test for most patients after resuscitation from a cardiac arrest to determine likely prognosis.
They owe it to patients and families to ensure they are doing the best to both not prolong unnecessary suffering while balancing that with not withdrawing care too soon if the person has the potential to recover with a reasonably good quality of life,” says Romergryko Geocadin, M.D., the chair of the expert panel and professor of neurology, neurosurgery, and anesthesiology and critical care medicine at the Johns Hopkins University School of Medicine.
“At the current state of affairs, they have to acknowledge; so the limitations in our practices in this area because we don’t have high-quality science to back our decision-making.” According to the statement, about 8% of the more than 320,000 people who have cardiac arrest outside of a health care setting in the U.S. are release from the hospital with a good outcome, whereas the vast majority of resuscitated patients end up in a coma or another state of consciousness due to brain injury.
Sedatives also influence
During a cardiac arrest, there are two stages of brain injury: One is due to lack of oxygen and the other happens, ironically, after blood returns. Healing may not begin until after the patient has clear this hurdle; which may take at least a week after the cardiac arrest. This further muddies the decision for how long to wait for a patient to awaken. Sedatives may also influence some of the diagnostics that determine brain function; so the authors generally recommend waiting seven days or until after the patient comes off sedatives, whichever happens later.
By using existing or yet to be develop tools properly in better design studies; so they hope researchers can adopt these procedures or enhance them; so to create better diagnostics for predicting long-term brain function. The statement offers clinician researchers parameters for setting up their studies; such as how many people they need to enroll, what statistical methods to use; hence when to reassess function in those that do recover, ways to avoid bias and applying protocols consistently.
The statement’s final section addresses ethical issues like respecting patient or family wishes for being on life support and do-not-resuscitate orders. The authors address that quality of life is an important factor; also stress that currently there is limit data regarding long term outcomes after awakening and more work needs to be done.
