Patient-controlled sedation (PCS) with propofol has been used successfully
as an adjunct to local anaesthetic procedures. We studied a group of
elderly patients (mean age 75.4 yr) undergoing cataract surgery and
attempted to increase patient acceptability and comfort of local
anaesthesia. Propofol was self-administered in a dose of 0.25 mg kg-1 for
patients more than 60 yr of age, with a lockout period of 3 min. A total of
14 of 20 patients used PCS; eight of 20 used the PCS only once and another
six had three tries or less. Despite this, 18 of 20 patients claimed they
found the PCS useful. However, while it is possible to administer PCS
successfully to elderly patients undergoing cataract surgery and produce a
decrease in the level of anxiety, we found it unacceptable because of head
movement in two patients. These patients received only two and three
divided doses, to a maximum of 29 and 30 mg, respectively. There were no
other adverse events.
