Procedural Pain and Distress in Children – What you do not know may harm them.-Walco – Procedural Pain and Distress in Children

Video Transcription

Video Summary

Dr. Gary Wolko’s talk focuses on procedural distress in children and argues that “pain” and “anxiety/stress” cannot be cleanly separated in clinical practice. He critiques older mind–body split models (traced historically to Descartes) that treated pain as either purely physiological or “in the head,” and instead emphasizes integrated, holistic models showing shared brain circuits and neurotransmitters for pain, stress, and anxiety. Functional imaging demonstrates overlap in regions such as the anterior cingulate cortex and insula, and psychiatric literature implicates neurotransmitters like serotonin, norepinephrine—and even substance P—in anxiety as well as pain.<br /><br />He reviews research showing poor correlation between children’s self-report, observed behaviors, and physiological measures (e.g., heart rate, cortisol), explaining that children can appear calm while highly aroused or vice versa. He highlights developmental vulnerability: inadequately treated pain in infants/young children can alter peripheral nerve growth, reduce precise localization, and contribute to central sensitization, with possible long-term psychological trauma effects linked to later chronic pain risk.<br /><br />Clinically, he recommends treating both nociception and anxiety, tailoring approaches to procedure invasiveness, developmental level, temperament, and coping style (attenders vs distractors). Parent behavior matters: criticism, reassurance, apologies, threats, and inappropriate control worsen distress; distraction, humor, coping coaching, and appropriate control help. He frames preventable procedural pain as an ethical issue and connects early traumatic dental experiences to widespread dental anxiety and avoidance cycles.
