Deep chest compression can reduce brain damage during cardiac arrest
New research found that deep chest compressions can break ribs, but it can be helpful to prevent brain damage during cardiac arrest.When the heart stops beating cardiac arrest occurs. To resuscitate a person with cardiac arrest, chest compressions might be done as soon as possible. The depth of each compression should 2 to 2.4 inches, for adults.
These compressions should be done at a rate of 100-120 compressions per minute, on the sternum that is center of the chest. This is the same for both males and females. When compressions are proper, deep chest compressions can make a racking sound. This is because of the fracture of cartilage or ribs
Commonly the injury is not much serious.
New research at the University Hospital La Paz in Spain states that deep chest compressions can break ribs, but it can prevent brain damage during cardiac arrest. According to studies, it improves the blood flow to the brain, by improving the survival and functioning of the brain.
The guidelines or cardiopulmonary resuscitation (CPR) are updated every five years and are used to train health care professionals and members of the public.
Concerns Over Deeper Chest Compressions
According to 2015 recommendations for deeper chest compressions created concerns over the possibility of increasing injuries related to CPR.
The latest study, presented at ESC Congress 2020 The Digital Experience, examined the effect of this advice on neurological outcomes in patients of cardiac arrest. It also assessed the rate of CPR-related injuries and their association with the diagnosis. Researchers say that they need to examine the effect of deep chest compressions during prolonged resuscitation when they could make a real difference to results.
22.7 Percent CPR Related Injuries Reported In 2016-2020
In between the year from 2006 to 2020, the study enrolled consecutive patients admitted to an acute cardiac care unit after getting a cardiac arrest in the hospital or in the community. Patients were divided into three groups corresponding to the updates of the CPR guidelines: 2006-2010, 2011-2015, and 2016-2020. This study included 510 patients who survived cardiac arrest and were admitted to the hospital while unconscious. The average age of those patients was 63 years and 81 percent were males. CPR by lay bystanders and the use of automated external defibrillators (AEDs) gradually increased over the study period.
After 2010, there was a higher ratio of CPR-related injuries: 12.7 percent in 2006-2010, 23.5 percent in 2011-2015, and 22.7 percent in 2016-2020. Just over half of the patients survived and got discharged from the hospital (51.6 percent).
Patients with Such Injuries Reported Better Brain Performance
The performance of the brain significantly increased over the course of the study, in three months. (i.e. it was highest in the 2016-2020 group).
The studies showed that patients with CPR-related injuries were more likely to have better brain functioning. Almost, two-thirds (65.1 percent) of patients with injuries had high brain function compared to 43.2 percent without the injuries.
The most common injuries are rib or sternal fractures. Survival and neurological outcome also improved gradually during the 14-year study.
