Abstract
OBJECTIVE: To establish the advantages and disadvantages of three sedation techniques for day care cataract surgery. DESIGN: Randomized allocation of patients into three groups comprising: no sedation, oral temazepam or intravenous fentanyl and droperidol. Assessment of patient anxiety, operating conditions and postoperative recovery by linear analogue anxiety scale, questionnaire and reaction time testing. Surgeons were unaware of the nature of the sedation given. SETTING: Day care cataract ophthalmic surgical unit. PATIENTS: Patients undergoing local anaesthetic day care cataract surgery at Leicester Royal Infirmary. RESULTS: Patients given intravenous fentanyl and droperidol were the least restless during surgery but this was associated with more postoperative problems and a longer hospital stay. Oral temazepam was associated with an increased pain score during the operation. Patients having temazepam were the most restless during surgery. CONCLUSION: No sedation provides operating conditions at least as good as oral temazepam and because postoperative problems are avoided, no sedation may be the best technique for day care local anaesthetic cataract surgery.
