The control of pain is crucial for the provision of good day-case anaesthesia. There must be good communication between the anaesthetist and the patient to increase compliance with the prescribed medication and ensure that the patient's expectations are realistic. Many patients are reluctant to take tablets because of worries about side-effects and drug dependence. Often, they expect and tolerate unnecessarily high levels of pain. Before surgery, the methods of analgesia for the specific procedure should be explained and discussed and, if applicable, consent obtained for local techniques and rectal drug administration. Fear about side-effects can be addressed at this stage.
