Autoresuscitation is a phenomenon of the heart during which it can resume its spontaneous activity and generate circulation. It was described for the first time by K. Linko in 1982 as a recovery after discontinued cardiopulmonary resuscitation (CPR). J.G. Bray named the recovery from death the Lazarus phenomenon in 1993. It is based on a biblical story of Jesus’ resurrection of Lazarus four days after confirmation of his death. Up to the end of 2022, 76 cases (coming from 27 countries) of spontaneous recovery after death were reported; among them, 10 occurred in children. The youngest patient was 9 months old, and the oldest was 97 years old. The longest resuscitation lasted 90 min, but the shortest was 6 min. Cardiac arrest occurred in and out of the hospital. The majority of the patients suffered from many diseases. In most cases of the Lazarus phenomenon, the observed rhythms at cardiac arrest were non-shockable (Asystole, PEA). Survival time after death ranged from minutes to hours, days, and even months. Six patients with the Lazarus phenomenon reached full recovery without neurological impairment. Some of the causes leading to autoresuscitation presented here are hyperventilation and alkalosis, auto-PEEP, delayed drug action, hypothermia, intoxication, metabolic disorders (hyperkalemia), and unobserved minimal vital signs. To avoid Lazarus Syndrome, it is recommended that the patient be monitored for 10 min after discontinuing CPR. Knowledge about this phenomenon should be disseminated in the medical community in order to improve the reporting of such cases. The probability of autoresuscitation among older people is possible.

Background: The aim of the study was to assess the impact of having various sources of information in the field of first aid on the level of knowledge of dental and medical students, as well as to recognize if medical stereotypes exist in the domain of first aid. Methods: We tested 818 Native-(N) and English (E)—speaking students of medicine (M) and dentistry (D). The questionnaire was constructed in a way that it could detect the issues which created the biggest challenges to the students. It consisted of both theoretical and clinical questions. The intention was to find out whether there were any medical stereotypes. The students were asked to provide the sources of their knowledge to each question, and information about the presence of first aid classes at school. Results: We found medical stereotypes, but only in the questions pertaining to theory: questions concerning defibrillation, opening the airway in infants and the causes of airway obstruction of an unconscious adult. Correlations were found between the sources of knowledge with answers to the questions in each group of students and between the groups. The sources of knowledge in N students came mostly from school, or the students were not able (NA) to indicate the source of knowledge, but E groups gave out of school courses, mass media and their own knowledge (or from the others), as well as NA answers. Interestingly in ED group, among other answers, students also indicated schools as a source of their knowledge. Conclusions: We confirmed that medical stereotypes among dental and medical students exist, and they were not related to multiculturalism or the use of different sources of knowledge.

The Lazarus phenomenon (LP), also called auto-resuscitation, may happen after the end of ineffective cardiopulmonary resuscitation (CPR), or after death is confirmed in a person who did not undergo CPR, and heart activity returns spontaneously. The aim of the study was to focus on older individuals (aged >60) experiencing the LP and to analyse distractors that cause this phenomenon. Methods. PubMed, Scopus, and Web of Science electronic databases were searched to find cases of LP from the year 1982 until 31 December 2025. Of the 81 total cases found, 48 patients were included in the study. For the analysis they were divided into two subgroups dependent on age: No 1 (60–79), No 2 (≥80). Results. Based on the descriptive analysis, the causes of cardiac arrest were divided almost equally between cardiac and non-cardiac causes (47.6% and 52.3% respectively). Cardiac arrest occurred equally in the IH and OH. In 16 out of 37 cases where such data were reported, a return to consciousness was confirmed, representing 43.2%. Conclusions. In older people, even those of very advanced age, the Lazarus phenomenon may occur. Based on the analysis carried out and given the lack of available data and the small sample size (48 individuals), it is not possible at this stage to definitively identify the causes of LP in the elderly population. As a potential cause of LP, age-related changes should be taken into account. Given that LP also occurs in the older population, consideration should be given to the need for extended monitoring of vital signs following the declaration of death. With a view to raising awareness of LP, it seems appropriate to include information on this phenomenon in the CPR guidelines.
