Insights

Hypnosis significantly reduced distress in children before anorectal manometry (ARM). This brief intervention is feasible and well-received by children and parents, although distress during the procedure did not differ.

Area of Science:

  • Pediatric Gastroenterology
  • Psychological Interventions
  • Medical Procedure Support

Background:

  • Functional constipation is a common pediatric issue.
  • Anorectal manometry (ARM) is a diagnostic procedure that can cause distress in children.
  • Minimizing procedural distress is crucial for pediatric patient experience.

Purpose of the Study:

  • To evaluate the effectiveness and feasibility of using hypnosis to reduce distress in children undergoing ARM.
  • To assess the impact of a brief hypnosis session on children's anxiety before and during ARM.

Main Methods:

  • A partially-blinded randomized controlled pilot trial involving 32 children (ages 4-18) undergoing ARM.
  • Children were randomized to receive either a brief hypnosis session or standard care prior to the procedure.
  • Distress levels were assessed using the Observation Scale of Behavioral Distress and a 4-point Likert scale by blinded and non-blinded observers.

Main Results:

  • Children in the hypnosis group showed significantly lower distress levels before ARM compared to the standard care group (P=0.009 and P=0.044).
  • No significant differences in distress were observed during the ARM procedure itself.
  • Hypnosis was positively perceived, with 92.9% of parents and children reporting it helped with relaxation. No procedural differences were noted.

Conclusions:

  • A brief hypnosis session is an easily integrated intervention to lower pre-procedural distress in children undergoing ARM.
  • Hypnosis is a feasible and positively received method for managing pediatric procedural anxiety.
  • Further research may explore sustained effects and broader applications in pediatric procedures.
