Day ophthalmic surgery: aspects of perioperative care

At Flinders Medical Centre in Adelaide, eye surgery under local anaesthesia (peribulbar block) has been carried out in the day ophthalmic surgery unit since 1987. In a subset of 536 patients, 112 patients required additional anaesthesia (supplementary retrobulbar block or regional muscle infiltration) to achieve full ocular paresis, and 10 patients required intraoperative supplementation of anaesthesia because of discomfort. Six patients had their surgery postponed (one had a retrobulbar haemorrhage and five became anxious after the procedure commenced). Sedation was rarely required and there were no adverse effects of the anaesthetic on surgical procedures or patients' vision. The authors conclude that peribulbar block provides satisfactory anaesthesia and that day ophthalmic surgery is safe and effective.
