Abstract

BACKGROUND Cardiopulmonary resuscitation (CPR), although lifesaving may cause chest wall injury (CWI) because of the physical force exerted on the thorax. The impact of CWI on clinical outcome in this patient group is unclear. The primary aim of this study was to investigate the incidence of CPR-related CWI and the secondary aim to study injury pattern, length of stay (LOS), and mortality in patients with and without CWI. METHODS This is a retrospective study of adult patients who were admitted to our hospital due to cardiac arrest (CA) during 2012 to 2020. Patients were identified in the Swedish CPR Registry and those undergoing CT of the thorax within 2 weeks after CPR were included. Patients with traumatic CA, chest wall surgery prior or after CA were excluded. Demographic data, type and length of CPR, type of CWI, LOS on mechanical ventilator (MV), in intensive care unit (ICU) and in hospital (H), and mortality were studied. RESULTS Of 1,715 CA patients, 245 met the criteria for inclusion. The majority (79%) of the patients suffered from CWI. Chondral injuries and rib fractures were more common than sternum fractures (95% vs. 57%), and 14% had a radiological flail segment. Patients with CWI were older (66.5 ± 15.4 vs. 52.5 ± 15.2, p < 0.001). No difference was seen in MV-LOS (3 [0–43] vs. 3 [0–22]; p = 0.430), ICU-LOS (3 [0–48] vs. 3 [0–24]; p = 0.427), and H-LOS (5.5 [0–85] vs. 9.0 [1–53]; p = 0.306) in patients with or without CWI. Overall mortality within 30 days was higher with CWI (68% vs. 47%, p = 0.007). CONCLUSION Chest wall injuries are common after CPR and 14% of patients had a flail segment on CT. Elderly patients have an increased risk of CWI, and a higher overall mortality is seen in patients with CWI. LEVEL OF EVIDENCE Prognostic and Epidemiological; Level IV.
