AbstractInvestigators from Bristol described a fentanyl- and diclofenac-based analgesic technique for tonsillectomy with low postoperative nausea and vomiting rates and low pain scores. This study compared the effectiveness of a modified Bristol technique with a codeine-based regimen with respect to PONV and analgesia. Sixty-five children, ASA 1-2, were randomly assigned to either the Bristol group (fentanyl 1-2 μg.kg(-1) and diclofenac 1-2 mg.kg(-1)) or codeine group (codeine 1.5 mg.kg(-1)). All children received paracetamol 15 mg.kg(-1) and dexamethasone 0.1 mg.kg(-1) . Postoperative nausea and vomiting and pain scores were recorded hourly, and fitness for discharge was assessed at 4 h. The overall incidence of postoperative nausea and vomiting was 21% with no difference between groups (Bristol group 8/30, codeine group 5/32, p = 0.29). Children in the Bristol group required analgesia earlier than those in the codeine group (p < 0.005), but maximum pain scores were not different (Bristol group median (IQR [range) 4.5 (3-5 [0-5]), codeine group 4.0 (2-5 [1-5]), p = 0.15). Twenty-three per cent of children were assessed as not fit for discharge at 4 h. The codeine-based regimen may have a small advantage over the Bristol regimen, but neither technique seems ideally suited for a day-case service without a longer period of observation.
