Objective: The knowledge and skills of the nurses about the newborn resuscitation are very important in terms of the survival of the baby. In this study, it was aimed to determine the knowledge level of crisis management education based on the simulation given to neonatal intensive care nurses and the effect of debriefing on self-evaluation. Material and Methods:This study was conducted with a semi-experimental, onegroup pre-test and post-test research design. Participants were 79 neonate nurses who successfully completed the both in class neonatal nursing and newborn resuscitation training programs among the 157 nurses working in the newborn intensive care unit in a private hospital. Pre-test and post-test were applied to the nurses in the sample group before and after the “Newborn Crisis Management in the Delivery Room” simulation training. Prior to and after the analysis of the simulation training, self-evaluation was provided with the “Newborn Resuscitation Participatory Self-Evaluation Form” and opinions about the training were obtained at the end of the training. The data that was obtained in the research was analyzed with IBM SPSS Statistics 22 Turkish. Results: The majority of participants (50.6%) are university graduates. According to the duration of the experience on neonatal intensive care unit, 29.1% of the participant were 0-12 months, 38% of were 13-36 months, 32.9% of were 37 months and over. The average pre-test was 57.09±11.05 in the pre- training period, whereas the posttest post-test average was 70.13±11.35 in the post-training period. According to the pre-training, the increase in the cognitive levels of the participants after the training was statistically significant. When the results of the self-evaluation of participants were examined, “Prepared aspirator”, “checked oxygen source”, “prepared hypothermia protective clothing”, “suction the mouth first then the nose” steps were found to be “missing/wrong” or unperformed, although they did not make the statistical significance. Conclusion: As a result, simulationbased trainings provide experience and allows student to learn from their mistakes. Newborn resuscitation training given in the simulation environment contributes to awareness and self-evaluation as well as cognitive development. We can say that applications that are incomplete or incorrectly constructed or not at all are the result of not reflecting a complete emotional resemblance, despite the provision of physical and conceptual similarity. Although this seems to be a disadvantage of the simulation training, we can say that the simulation method is an effective way to develop nurses without harming the actual patient.
