Purpose: To examine the reasons for unplanned overnight hospital admission in paediatric patients undergoing strabismus repair, to identify preventable causes (particularly postoperative nausea and vomiting), and to compare the rate of unplanned overnight stay with a group undergoing inguinal hernia repair.
Method: A retrospective review of consecutive patients under age 17 having strabismus surgery over a 5-year period between January 1995 and December 1999 was undertaken at Christchurch Hospital, New Zealand. A control group, from a similar period, of children having elective inguinal hernia repair was used to compare the rate of overnight stay.
