Deep chest compressions can crack ribs, but they reduce brain damage during cardiac arrest, reports a study presented today at ESC Congress 2020.

The 2010 recommendation for deeper chest compressions generated concerns over the possibility of increasing CPR-related injuries. This study examined the impact of this advice on neurological outcomes in survivors of cardiac arrest. It also assessed the rate of CPR-related injuries and their association with prognosis.

In 2006 to 2020, the study enrolled consecutive patients admitted to an acute cardiac care unit after a cardiac arrest in hospital or in the community. Patients were divided into three groups corresponding to updates of the CPR guidelines: 2006–2010, 2011–2015, and 2016–2020.

The study included 510 patients who survived cardiac arrest and were admitted to hospital while unconscious. The average age was 63 years and 81% were men. CPR by lay bystanders and the use of automated external defibrillators (AEDs) progressively increased over the study period.

After 2010, there was a higher proportion of CPR-related injuries: 12.7% in 2006–2010, 23.5% in 2011–2015, 22.7% in 2016–2020. Just over half of patients survived and were discharged from the hospital (51.6%). Brain performance at three months significantly increased over the course of the study (i.e. it was highest in the 2016–2020 group).

Patients with CPR-related injuries were more likely to have better brain performance. Nearly two-thirds (65.1%) of patients with injuries had high brain function compared to 43.2% without injuries. The most common injuries were rib or sternal fractures.

“Survival and neurological outcome improved significantly during the 14-year study,” said researchers. “Members of the public increasingly came to the rescue with CPR and there was greater use of AEDs. Injuries from CPR rose, but these patients were less likely to have brain damage.”
