BACKGROUND: The purpose of this study is to attempt to evaluate the knowledge of medical rescue personnel within the scope of advanced resuscitation procedures in children. MATERIALS AND METHOD: We conducted a quantitative survey. The study included a group of 482 medical personnel. The knowledge of medical staff was assessed by their correct answers to the survey questions. RESULTS: Especially among nurses, there was insufficient knowledge of the following issues: determination of the child's body weight (32-62%), the second dose of amiodarone during resuscitation of the child (42-90%), the volume of fluids used during fluid resuscitation (47-100%). CONCLUSIONS: Among studied groups, nurses are the worst prepared for conducting resuscitation in children. Nurses presented a low level of knowledge within the scope of advanced resuscitation procedures in children.
