BACKGROUND: Pain is considered as being one cause of post-operative emergence agitation (EA) from sevoflurane anaesthesia. The purpose of this study was to investigate the pure effect of post-operative pain on EA after sevoflurane anaesthesia in preschool children undergoing excision of scalp nevi.
METHODS: Forty-four children, 1-7 years old, undergoing scalp nevus excision were enrolled. Patients were randomly assigned to two groups: the remifentanil group received single intravenous injection of short-acting synthetic opioid, remifentanil 1 mug/kg just before the scalp incision, and the block group received scalp nerve block with 0.25% ropivacaine after intubation. The end-tidal sevoflurane concentration was maintained around 1.5 vol% unless the mean arterial pressure is out of +/-20% range of preoperative values during surgery in both groups. Watcha behaviour scale for EA and face, legs, activity, cry, consolability (FLACC) scale scores for pain were recorded post-operatively.
RESULTS: There was no difference in end-tidal sevoflurane concentration between the two groups during surgery and the emergence period. Agitation incidence and scores were not different between the two groups during the recovery period. FLACC scale was significantly lower in the block group than in the remifentanil group at post-anaesthesia care unit (PACU) arrival, at 10 and 20 min after PACU arrival, respectively.
CONCLUSION: The scalp nerve block decreased the early post-operative pain after paediatric nevus excision, but it did not decrease the incidence of EA with sevoflurane anaesthesia.
