Effects of parental holding on pain response in young children during cystometry: A randomized controlled trial.

Introduction: Cystometry is essential for evaluating bladder function. However, children may react negatively to the physical pain of urethral catheterization or anxiety and fear of an unfamiliar environment. These pain responses during the cystometry procedure may interfere with the cystometry procedure and make it difficult to interpret the cystometry result. In this regard, the International Children's Continence Society has advised performing cystometry while holding infants as an effective nonpharmacological pain management method, but there is insufficient evidence to support this.

Purpose: This study aimed to analyze the effect of parental holding on reducing pain in children during cystometry.

Methods: This was an experimental study in a randomized controlled pre-post test design. A total of 64 participants aged 6-18 months were recruited. During cystometry, the participants in the experimental group were placed on the parent's laps and held in the parents' arms. The participants in the control group were laid down on the examination table. During the procedure, both groups of parents were allowed to touch their children in all ways except holding them and to use the pacifier if they wished. The behavioral (face, leg, activity, cry, consolability scale) and physiological (oxygen saturation and heart rate) pain responses were measured at three-time points (immediately, 3, and 10 min after urethral catheter insertion).

Results: Comparing the two groups, in the experimental group, the behavioral pain response at 3 min after urethral catheter insertion (t = -2.165, p = 0.034) and 10 min after (t = -3.155, p = 0.002) was decreased compared with that immediately after urethral catheter insertion. In addition, oxygen saturation increased more (t = 2.021, p = 0.048), and the heart rate decreased more (t = -2.033, p = 0.047) at 10 min than at 3 min after urethral catheter insertion in the experimental group.

Conclusions: This study revealed that parental holding could reduce pain responses during cystometry in children. Further research is required to confirm the applicability and usefulness of parental holding during cystometry.
