In a double blind study 40 patients, aged 1-9 years, undergoing electi
ve minor surgery were examined and randomly divided in two groups (20
children each). After light general anaesthesia Group 1 received cauda
l injection of bupivacaine 0.25% 2 mg.kg(-1) while Group 2 received 0.
2% ropivacaine 2 mg.kg(-1). No differences were observed in demographi
c data, HR, BP and duration of surgery; the onset time of anaesthesia
was 12 min and 9 min in Group 1 and 2 respectively. Ten patients in Gr
oup 1 received paracetamol in the first 24 h after surgery while only
two children in Group 2 needed analgesic; even the duration of analges
ia in the patients requiring paracetamol was superior in group 2 (520
min vs 253 min). No motor block was apparent at awakening in either gr
oup and no side effect was noticed. In conclusion ropivacaine seems to
be an effective and safe drug in paediatric regional anaesthesia.
