Cardiac arrest & resuscitation
Impact of chest wall injuries after cardiopulmonary resuscitation in non-traumatic and successfully resuscitated cardiac arrest: insights from the DISCAR study
Authors' conclusion
CWI in successfully resuscitated UCA patients are frequent, clinically largely underdiagnosed, and may be associated with lower 28-day-survival with ventilator-free-days.
Study context
- Population
- Non-traumatic adults hospitalized in ICU after successfully resuscitated unexpected cardiac arrest, excluding ECLS or death within 48 h
- Participants
- 383 adults
- Exposure
- Chest wall injuries (CWI) vs no CWI
- CWIn = 101
- Outcome
- 28-day survival with ventilator-free days
- Follow-up
- 28 days
Methodological detailssingle-centre
- Single-centre
Main finding
As reported in the abstract
- CWI vs Non-CWI: P < 0.001
Observational data: associations, not effects.
Further findings
| Outcome | P value |
|---|---|
| In-ICU length of stayIncreased with CWI | P = 0.017 |
- Prevalence of CWI
- 26 % · 101
- Prevalence of CWI — Diagnosed only clinically
- 4
- Prevalence of CWI — Diagnosed with CT-scan alone
- 87
- Prevalence of CWI — Diagnosed with both, concordant
- 10
- Prevalence of CWI: Chest CT performed in 174 patients (45 %)
Survival with favourable neurological outcome (multivariable)
- Age, bystander CPR, no-flow and low-flow durations, shockable rhythm, but not CWI, independently associated
Factors associated with CWI (multivariable)
- Older age, prolonged low-flow duration and hypoxic unexpected cardiac arrest (UCA) independently associated with CWI
