Resuscitating the resuscitation: A single-centre experience on extracorporeal cardiopulmonary resuscitation.

AIM

Extracorporeal cardiopulmonary resuscitation (ECPR) is the rapid deployment of venoarterial extracorporeal membrane oxygenation (ECMO) during active cardiopulmonary resuscitation or in patients with intermittent return of spontaneous circulation. This study aimed to describe the demographic characteristics and outcomes of patients undergoing ECPR to identify survival-associated factors.

METHODS

The study was conducted in an extracorporeal life support centre of a tertiary hospital in Turkey and included all patients who underwent ECPR for in-hospital cardiac arrest between April 2013 and June 2021. Complications included bleeding, neurological injury, renal failure, hepatic failure, limb ischemia and bloodstream infections. The primary outcomes were survival of ECMO and survival to discharge. Neurological outcomes were assessed using the Pediatric Cerebral Performance Category Scale for children and the Category of Cerebral Performance Scale for adults.

RESULTS

The study included 26 patients (24 paediatric, 2 adults), 22 (85%) of them had cardiac pathology. Bleeding was the most common complication. Twelve (46%) patients survived ECMO, 9 (35%) survived to discharge. Sex, age, primary diagnosis, cardiac arrest rhythm and ECMO duration were not significantly associated with the primary outcomes. Bleeding, neurological injury and renal failure were associated with poorer survival to discharge. The neurological outcomes of all survivors to discharge were good.

CONCLUSIONS

ECPR is not commonly accessible. Sharing the experience of the few treating centres to date is crucial to accumulating sufficient knowledge about its efficiency and raising clinician awareness. This limited single-centre experience demonstrated the utility of ECPR.
