Hypnosis Reduces Distress and Duration of an Invasive Medical Procedure for Children

Abstract

Hypnotic relaxation may provide a systematic method for improving the overall medical care of children with urinary tract abnormalities and may be beneficial for children who undergo other invasive medical procedures. Because the VCUG is an essential part of the evaluation of urinary tract infections and vesicoureteral reflux in children, lower distress during the procedure may improve patient and family compliance with initial as well as follow-up evaluations. These findings augment the accumulating literature demonstrating the benefits of using hypnosis to reduce distress in the pediatric setting. The present findings are noteworthy in that this study was a controlled, randomized trial conducted in a naturalistic medical setting. In this context, we achieved a convergence of subjective and objective outcomes with moderate to large effect sizes, including those that may have an impact on patient care and procedure cost, that were consistently supportive of the beneficial effects of hypnosis-a noninvasive intervention with minimal risk. The findings, therefore, have immediate implications for pediatric care. Limitations of this study include the lack of participant and staff blindness to the child's condition assignment, which could have introduced bias into reports. However, the objective procedural time differences between groups were consistent with the other, more subjective outcome findings. The sample was also small and primarily white in ethnic/racial makeup, which may have restricted our ability to detect some differences and may limit the generalizability of findings to more representative samples. In addition, the sample comprised children who had already undergone at least 1 VCUG during which they had had difficulty. Consequently, additional research is needed to determine whether hypnosis would be helpful to those who are undergoing their first VCUG. Additional limitations, clinical observations, and directions for future research are also discussed.
