Two hundred patients completed a questionnaire about their experiences
of patient-controlled analgesia. The questionnaire covered the follow
ing topics: pre-operative information, reasons for pressing and not pr
essing the button, pain relief, side-effects, safety, advantages and d
isadvantages of patient-controlled analgesia, worries associated with
its use and control over pain. A high level oi satisfaction with the d
evice, together with a view that it afforded control over pain, emerge
d from replies to simple, general questions, However, more detailed qu
estions revealed side-effects and fears that constrained its use and h
ence patients' ability to control pain. Control is predominantly a fea
ture of the professional's view of patient-controlled analgesia, rathe
r than the patient's experience of this analgesic technique.
