Could a drug combo make Kids' foot surgery less painful?
NCT ID NCT07289620
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether adding dexamethasone, dexmedetomidine, or both to a standard numbing shot can make pain relief last longer after foot or ankle surgery in children aged 3 to 12. About 120 kids will get one of three combinations, and neither they nor their doctors will know which. The goal is to see if the combo reduces the need for extra pain medicine and improves comfort.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- dexamethasone and dexmedetomidine
- What this could lead to
- If it works, this could point toward a better way to manage pain after foot surgery in children, reducing the need for strong painkillers.
- What could go wrong
- This is a small, early-stage study (120 children) comparing existing drugs, so results may not apply to all patients. The combination might not work better than either drug alone.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Children aged 3 to 12 years. * Scheduled for elective unilateral lower limb surgery (foot, ankle, or distal lower leg) under general anesthesia with a popliteal sciatic nerve block planned for postoperative analgesia. * ASA physical status I-III. * Ability of parents or legal guardians to understand the study procedures and provide written informed consent. * Child and parents/guardians available for telephone follow-up at 1 week and 1 month after surgery. Exclusion Criteria: * Refusal of the parents/legal guardians to provide informed consent or refusal of the child to cooperate with anesthesia or study procedures. * Known allergy or hypersensitivity to ropivacaine, dexamethasone, dexmedetomidine, or any component of the study medications. * Pre-existing neurological deficit or neuromuscular disease affecting the lower limbs (motor or sensory). * Coagulopathy or current therapeutic anticoagulation that contraindicates regional anesthesia. * Local infection, inflammation, or skin lesions at the planned block site. * Severe cardiac, hepatic, renal, or respiratory disease that, in the investigator's opinion, increases the risk of study participation. * History of clinically significant arrhythmias, severe bradycardia, or second/third degree atrioventricular block not treated with a pacemaker. * Developmental delay or severe cognitive impairment that precludes reliable pain assessment or follow-up. * Chronic use of opioid analgesics or sedatives (≥ 2 weeks of daily use before surgery). * Participation in another interventional clinical trial within the last 30 days. * Any other condition considered by the investigator to interfere with protocol adherence, safety monitoring, or reliable outcome assessment.
