VR During Accessing a Port With Huber Needle

Study hypotheses H1: The venous port access-related pain, fear and anxiety scores of patients in VR group during access the venous port with Huber needle is lower from the control group.

Methods Study Design and Sample This is a randomized controlled study of virtual reality during access the venous port with Huber needle performed in a pediatric hematology and oncology setting at two university hospital in Izmir. Data were recorded on 42 children and adolescents with cancer aged 6-17 undergoing Huber needle insertion into a subcutaneously implanted intravenous port.

Gpower 3.1.0 statistical program showed that 21 patients in each group were needed based on an effect size of 0.20, at a power of 0.80, and an acceptable type I error size of 0.05.

Randomization Forty-two children enrolled the study. They were allocated by the blocked randomization; gender, age (6-12/13-18), subcutaneously implanted intravenous port insertion time (≤1month/>1month). Randomization was performed with a computerized random-number generator. Forty-six children were assessed for eligibility; 4 children were excluded; refused to participate (n = 2); had visual problem (n = 1); did not want to wear VR glasses to see access the venous port with Huber needle before the procedure (n = 1).

Instruments Demographic Form. This form included the child's gender, age, the last blood draw time, blood draw success and also the parent demographics such as age, educational level.
