This prospective randomized controlled study was conducted in the pediatric hematology and oncology polyclinic blood collection unit of a university hospital in Turkey.~Patients undergoing phelobotomy were allocated to virtual reality or control groups according to a stratified randomization scheme.
In this study, the effect of virtual reality, which is one of the pain relief methods, on the pain, fear and emotional appearance associated with the procedure, was evaluated in children aged 4-12 years who will undergo phelobotomy in a Pediatric Hematology and Oncology outpatient clinic.
