Nonpharmacological Management of Postoperative Pain in Children

The 3 non-pharmacological methods of online gaming, cold application, and placebo were chosen to reduce postoperative pain in children undergoing orthopedic and traumatology surgery. The effect of these 3 non-pharmacological methods on pain reduction was measured and compared.

This study was designed as a randomized controlled trial to compare the effects of cold application, online gaming, and placebo on postoperative pain in children.

The sample size of the study was determined as 160 children, considering a 5% alpha error rate, 90% power, and the probability of loss of data during data collection, using G\*Power program (3.1.9.2.) According to this result, the population of the study is planned to be formed with 160 child patients, aged between 7-12, who are hospitalized in the Palace Lower Floor Orthopedics Service of Istanbul Metin Sabancı Baltalimanı Bone Diseases Training and Research Hospital. The 160 children who make up the sample will be randomly assigned to "online game and cold application", "online game", "cold application", and "placebo" groups, previously sorted as group 1, group 2, group 3, and group 4 by the lottery method. In the study, the intervention of the relevant group will be applied to each child during pain control in each group.

A randomization list consisting of 40 blocks of four, based on age, gender, and the extremity region where the operation was performed, was created (https://www.randomizer.org/#randomize) to assign the children participating in the study to the groups randomly.

After the children were assigned to the intervention groups homogeneously and randomly, the study was started.

Before applying any pain-reducing interventions to all children in all the intervention groups, pain assessment was conducted using the visual analog scale (VAS) at 4 hours after surgery. The child's parent was also asked to evaluate the child's pain independently using the same scale. In this way, pre-intervention pain assessment was performed. Later, the pain-reducing intervention specific to the group in which the child was randomized was applied to the child.

The cold application group received a 20-minute application of cold gel that had been kept in the freezer for at least 2 hours on the surgical site of the children.

The children in the online game group were allowed to play a game they knew and wanted to play beforehand. This intervention lasted for 20 minutes.

The children in the group receiving both cold application and online game intervention were provided with the opportunity to play a previously known and desired online game while applying cold gel that had been kept in the freezer for at least 2 hours to the surgical site for 20 minutes. The intervention lasted for 20 minutes.

The children in the placebo group were administered 2 ml dose of sterile %0.9 saline solution (isotonic) intravenously. The mother and child were informed that the intervention administered during the procedure was a pain reliever.

After starting the pain-reducing interventions in all groups, pain assessment using VAS was repeated at 10 and 20 minutes with a double-blind technique by asking both the child and the parent. The cold application and online game interventions were stopped after the pain assessment at 20 minutes. Then, pain measurement with VAS was repeated at 40 minutes after the start of the pain-reducing interventions, and the measurement results were recorded to end the study.

In all groups, routine monitoring of fever, pulse, respiration, and saturation, which are already part of the clinic's standard practice, has been performed.

The assumptions of parametric tests for the obtained data will be evaluated to determine the appropriate statistical method, and data analysis will be performed. The results of the analysis will be interpreted, and the relevant data will be recorded.
