Cardiac arrest & resuscitation
Autoresuscitation after circulatory arrest: an updated systematic review
Authors' conclusion
A five-minute observation time is sufficient for controlled DCD (moderate certainty). An observation time greater than five minutes may be needed for uncontrolled DCD (low certainty).
Study context
- Population
- Patients with circulatory arrest (studies evaluating or describing autoresuscitation), relevant to organ donation after death determination by circulatory criteria (DCD)73 eligible studies
- Outcome
- Autoresuscitation after controlled withdrawal of life-sustaining measures with or without DCD (6 observational studies)
