Nurse anaesthetic care during cataract surgery: a comparative quality assurance study

We studied whether a new model of nurse-provision of conscious sedation for cataract surgery maintained patient satisfaction and safety.

We prospectively and non-randomly studied 106 patients who had outpatient cataract surgery on a day when an anaesthetist was present at the UBC, Vancouver Hospital Eye Care Centre, and 105 patients with no anaesthetist, but instead a surgical suite nurse trained to give conscious sedation was present. Questionnaires determined patient perception of well-being, pain, and anxiety before surgery, before discharge, at 48 hours and at 6 weeks postoperative. Hospital records and a surgeon questionnaire were used to determine complications. Ophthalmology records were used to determine visual acuity (preoperative and at 6 weeks).

No anaesthetic complications were reported in either group and there were no significant differences in surgical complications. Patient responses to assessments of discomfort, well-being, and anxiety, preoperatively and postoperatively, were very similar on the nurse days and anaesthetist days.

Conscious sedation of cataract surgery patients can be safely and effectively provided by a trained nurse for selected patients. This nursing role is likely replicable in similar operating room settings.
