Lazarus Phenomenon

Lazarus phenomenon refers to autoresuscitation of a patient declared dead after cessation of cardiopulmonary resuscitation (CPR). The Lazarus phenomenon is rarely encountered and pathophysiology is not very well understood, but physicians need to be aware of this phenomenon. It is prudent that a physician leading a CPR effort waits for some time and monitors the patient further using blood pressure and electrocardiogram before confirming that a patient is actually dead.

Abstract Background: High levels of arterial oxygen pressures (PaO2) have been associated with increased mortality in extracorporeal cardiopulmonary resuscitation (ECPR), but there is limited information regarding possible mechanisms linking hyperoxia and death in this setting, notably with respect to its hemodynamic consequences. We aimed therefore at evaluating a possible association between PaO2, circulatory failure and death during ECPR.Methods: We retrospectively analyzed 44 consecutive cardiac arrest (CA) patients treated with ECPR to determine the association between the mean PaO2 over the first 24h, arterial blood pressure, vasopressor and intravenous fluid therapies, mortality, and cause of deaths.Results: Eleven patients (25%) survived to hospital discharge. The main causes of death were refractory circulatory shock (46%) and neurological damage (24%). Compared to survivors, non survivors had significantly higher mean 24h PaO2 (306±121 mmHg vs 164±53 mmHg, p < 0.001), lower mean blood pressure and higher requirements in vasopressors and fluids, but displayed similar pulse pressure during the first 24h (an index of native cardiac recovery). The mean 24h PaO2 was significantly correlated with hypotension and vasoactive therapies. Patients dying from neurological cause had better preserved blood pressure and lower vasopressor requirements. Patients dying from circulatory failure died after a median of 17h, compared to a median of 58 h for patients dying from a neurological cause (OR 0.95, 95% CI 0.90–0.99, p = 0.001).Conclusion: In conclusion, hyperoxia is associated with increased mortality during ECPR, possibly by promoting circulatory collapse or delayed neurological damage.
