Purpose: To evaluate data about cardiopulmonary resuscitation (CPR) in Paediatric Intensive Care Unit (PICU) Ljubljana, and data about CPR in survivors of intra- and out-of-hospital cardiac arrest, who were admitted to PICU. The evaluation was performed in the view of preparation for introduction of the new uniform paediatric Utstein style based electronic report of CPR events in our hospital.
Methods: Retrospective analysis of the electronic and paper documentation of children admitted to PICU in the years 2017 and 2018. 
Results: Altogether 915 children were admitted to the PICU in the said period, among them 31 children (3.4%) needed CPR. The average age of resuscitated children was 26.8 (±42.1) months. According to the location resuscitation took place in PICU (45%), in the operating theatre (13%), other hospital departments (7%), other hospitals (19%), and out-of-hospital (16%). PICU cardiac arrests most commonly occurred during the winter (36%), and surprisingly, 21% in the short period during the changing of shifts (half an hour three-times per day).
The most common cause of cardiac arrest was circulatory failure (58%), followed by respiratory failure (39%), and trauma (3%). The mean resuscitation time was 23.7 (±32.4) minutes, and the most common cardiac arrest rhythm was terminal bradycardia (55%), followed by asystole (29%), PEA (6.5%), and VF (6.5%). ROSC was achieved in 71% of subjects. 64% of children survived until PICU discharge, and neurological outcome was favourable in 56% of them.
Conclusions: The lack of standardized form in reporting pediatric CPR in our country, which we have noticed during the research, should be addressed in the future, together with introducing the new electronic report of CPR events at our institution. Beside that, high level of CPR events during some particular periods in PICU (winter, shift changing time) should be addressed as well.
