Case ReportsClinical experience using intrathecal (IT) bupivacaine infusion in three patients with complex regional pain syndrome type I (CRPS-I).
To date, there is no reliable method for treating the severe pain and for modifying the natural evolution of CRPS-I. Therefore, we explored the effect of long-term IT bupivacaine infusion (with or without buprenorphine) on this syndrome. ⋯ The IT pain treatment with bupivacaine (with or without buprenorphine) alleviated the "refractory" pain, but affected neither the associated symptoms and signs of the CRPS-I, nor its natural evolution. Thus, the IT treatment cannot be recommended in preference to other pain treatment regimens for CRPS-I.

In five depressive patients associated with chronic pain, the efficacy of electroconvulsive therapy (ECT) for pain relief was evaluated retrospectively. In all of the patients treatment with tricyclic antidepressant medication was not successful, but ECT alleviated or diminished the chronic pain associated with depression. It seems that ECT as a treatment for chronic pain in patients with depression should be taken into consideration in cases in which other treatments have failed.

Over the last 10 years, there has been a fundamental change in physicians' attitudes toward analgesia and sedation in pediatrics. In this time, basic and clinical research have provided a wealth of information. ⋯ Fortunately, the attitude of physicians toward these matters has changed significantly and much more attention is now paid to the alleviation of pain and provision of adequate sedation. However, there remains, according to most estimates, incongruity between these advances and what is practiced clinically.

Levobupivacaine: a new safer long acting local anaesthetic agent.
The choice of local anaesthetic is influenced by several factors; it must provide effective anaesthesia and analgesia for the duration of the procedure and meet the expectations for post-operative pain management. Of primary concern is patient safety. Bupivacaine, currently the most widely used long acting local anaesthetic agent in both surgery and obstetrics, generally has a good safety record but its use has resulted in fatal cardiotoxicity, usually after accidental intravascular injection. ⋯ Nevertheless, levobupivacaine has been shown to have less effect on myocardial contractility and QTc prolongation, early signs of cardiotoxicity, than bupivacaine in healthy subjects. In clinical use levobupivacaine has been shown to be equally efficacious as bupivacaine at comparable doses and concentrations, and has been found to produce similar anaesthetic characteristics (onset, duration and density of block). As levobupivacaine now becomes commercially available, the database available with which to make efficacy and safety comparisons with other local anaesthetics will increase, and the true value of this new long acting local anaesthetic should become even more apparent.

Clinical TrialBarriers to better pain control in hospitalized patients.
Pain is often inadequately treated. To evaluate a common method of assessing pain and to identify some barriers to improving pain control, 50 hospitalized patients in pain, their nurses, and their physicians were interviewed about the pain experienced by the patients. The patients' "pain behavior" was assessed and literatures was reviewed to identify the risk for developing iatrogenic drug addiction in patients with no prior history of drug abuse. ⋯ Barriers to better pain control in acutely hospitalized patients include: (1) exaggerated fear of iatrogenic addiction, (2) an attitude among staff that patients exaggerate the intensity of their pain, (3) poor correlation between pain behavior and pain intensity that can mislead staff who rely on pain behavior to assess pain intensity, and (4) a lack of agreement between doctor and nurse in estimating the intensity of a patient's pain. A new way of thinking about patients in pain, assessing pain as either present or absent, is proposed for evaluation. If pain is present, one should attempt to ameliorate it in a manner consistent with the desire of the patient and the acceptability of adverse effects.
