Forty children undergoing strabismus surgery as day patients were rand
omly allocated to receive oxybuprocaine 0.4% eyedrops or 0.1% diclofen
ac eyedrops for perioperative analgesia. A non-invasive anaesthetic te
chnique using the reinforced laryngeal mask airway was used. The study
demonstrated that both topical analgesics provided good to excellent
analgesia and the anaesthetic technique was associated with a relative
ly low incidence of nausea and vomiting. Complications were limited to
two children who were admitted with persistent postoperative nausea a
nd vomiting.
