Observational trial of correlations between skin conductance and postoperative pain in children

This study is looking at whether a simple, painless test that measures sweating on the hand (called skin conductance) can help us understand how much pain a child is feeling after surgery. Right now, accurately measuring pain in young children — especially toddlers who cannot explain how they feel — is very difficult. Researchers will measure skin conductance using small sticky sensors on the hand at the same time that nurses assess pain using standard tools. The goal is to see if skin conductance could one day be used as an objective, pain-free way to measure a child's pain level. You may be eligible if: - Your child is between 1 and 16 years old - Your child is recovering from surgery in the post-anaesthesia recovery room You may NOT be eligible if: - Your child has developmental delay - Your child has a syndrome or major systemic medical condition - Your child takes medicines that affect the autonomic nervous system (such as anticholinergics, antidepressants, or ADHD medications) - Your child is classified as ASA category 3 or 4 (high anaesthetic risk) - Your child's hands are not accessible - Your child has a known reaction to adhesive patches Talk to your doctor about whether this trial might be right for you.
