Prolonged painful wound treatment in a child — DipIMC MCQ

ModerateAnalgesia, sedation and proceduresProlonged painful wound treatment in a childDipIMC

An enhanced-care team is assisting in a rural emergency department with a 9-year-old child who has a contaminated lower-leg laceration after falling through a greenhouse roof. Examination and radiographs show no fracture, tendon injury or neurovascular deficit. The wound needs extensive irrigation, removal of several superficial glass fragments and layered closure; the proceduralist estimates 40–50 minutes of repeated painful manipulation. The child is otherwise well, has intravenous access and remains distressed despite analgesia and reassurance. Staff and monitoring for paediatric procedural sedation are available, as is a theatre team. Which is the most appropriate procedural plan?

Correct answer: A — Arrange wound treatment in theatre under general anaesthesia.

The discriminator is the anticipated **40–50 minutes of repeated painful manipulation**, not a lack of sedation staff or equipment. RCEM describes intravenous ketamine as useful for short paediatric procedures, but advises considering theatre and general anaesthesia when a procedure is likely to exceed 20 minutes because sedation may fail during prolonged work. This child has no threatened limb requiring immediate ED treatment, and a theatre team is available; general anaesthesia is therefore the best plan for completing the procedure reliably. ([rcem.ac.uk](https://rcem.ac.uk/wp-content/uploads/2025/05/RCEM_BPC_Ketamine_Kids_27012020.pdf)) **B** is attractive because ketamine provides analgesia and can be supplemented, but its usual effective sedation period is 10–20 minutes, substantially shorter than the planned procedure. **C** offers titratable sedation, yet propofol does not itself provide analgesia and would require prolonged deep-sedation management alongside local anaesthesia. **D** is less suitable than intravenous ketamine when access already exists; RCEM notes longer recovery and more emesis with the intramuscular route. **E** can help with brief uncomfortable procedures, but is a poor match for sustained deep wound manipulation in a child who remains distressed despite initial measures.
