Randomized Controlled Trial Comparative Study Clinical Trial
Comparison of effects of intraoperative and postoperative methadone: acute tolerance to the postoperative dose?
The effects of methadone 10 mg administered in two different clinical contexts, at induction of anaesthesia and following operation, were studied in two groups of patients undergoing elective total hip replacement. The intraoperative group received methadone 10 mg i.v. at induction of anaesthesia as part of a balanced anaesthetic technique. The postoperative group received methadone 10 mg i.v. following operation, extradural bupivacaine being used for the operative period. ⋯ Subsequently, the postoperative group had a significantly greater analgesic requirement which resulted in significantly greater plasma methadone concentrations the following morning. Thus, the administration of methadone following operation appeared to exert less analgesic effect than the same dose given during operation. The reasons for this are discussed.

The incidence of pain in 170 children recovering from surgery was surveyed in two major teaching hospitals along with an analysis of analgesic medication prescribed and administered. Analgesic medication was not ordered for 16% of the patients and narcotic analgesic medication ordered was not given for 39% of the patients. In 29% of the patients, where an order for "narcotic or non-narcotic analgesic medication' was written, the non-narcotic drug was given exclusively. ⋯ Others expressed a dread of "the needle' as a way of administering analgesics and preferred to suffer pain to an injection. We have concluded that there is considerable scope to improve pain management in children after surgery. This improvement must be based on improved education of medical and nursing staff in contemporary clinical pharmacology and on improved communication between staff, parents and patients.

This study attempted to predict postoperative pain from preoperative level of anxiety and the amount of information patients possessed regarding their surgery. Pain was assessed via the McGill Pain Questionnaire (MPQ) and a measure of pain complaints--number of analgesics taken. ⋯ Biographical variables were unrelated to postoperative pain. The results were discussed in terms of State-Trait Anxiety theory, Janis' curvilinear prediction model and a contextual perspective of information imparting.
