These data suggest the presence of peripheral opioid receptors that are involved in the clinical perception of pain. This is a radical change in our traditional thinking of opioid pharmacology and pain management. Most clinicians have been taught that opioids work through the central nervous system. ⋯ Further data, specifically, additional dose-response data with varying amounts of morphine, additional studies in pain syndromes other than knee arthroscopy, and the development and pharmacology of orally active opioid compounds that do not cross the central nervous system, are necessary to confirm and expand the present findings. The possibility of providing opioid pain relief free of central nervous system adverse effects is an exciting prospect. Additional studies of topical opioid preparations also would be of interest.

Case ReportsThe risk of infection from epidural analgesia in children: a review of 1620 cases.
We reviewed cases to determine whether suspected or confirmed epidural infection was associated with epidural analgesia for 1620 infants, children, and adolescents treated over a 6-yr period at Children's Hospital, Boston. Postoperative patients (1458/1620) received epidural infusions for a median of 2 days (range, 0-8 days). No postoperative patient had an epidural abscess. ⋯ A second oncology patient and two patients with reflex sympathetic dystrophy were evaluated for epidural abscess, but none was found. We conclude that the risk of epidural infection is quite low in pediatric postoperative patients receiving short-term catheterization. Use of prolonged epidural analgesia in the management of chronic pain in children requires careful monitoring of warning signs of infection.

The purpose of this study was to determine the correlation between patient controlled analgesia and continuous epidural analgesia after total knee or total hip replacement on the length of hospital stay. Stress responses to postoperative pain, including decreased mobility, compromised respiratory function, increased catecholamine release, and hypercoagulation, may adversely affect patient recovery, thus lengthening hospital stay. A retrospective chart review of 127 adult, American Society of Anesthesiology (ASA) I, II, or III, patients who had undergone total knee arthroplasty (TKA) or total hip replacement (THR) was obtained. ⋯ These findings were not statistically significant at P = 0.054. LOS did not correlate with age, weight, height, type or surgery, or the ASA classification. Further research into the effectiveness of continuous infusion of epidural bupivacaine and epidural morphine and their impact on LOS may be warranted.

A postal survey of all maternity units in the UK was conducted to gain information regarding the management of inadvertent dural taps occurring during the sitting of epidurals for pain relief in labour. Of the units surveyed only 58.5% had a written protocol for the management of dural taps. ⋯ In 46% of the units, patients who had a dural tap were allowed to push in the second stage of labour. As prophylaxis against the development of headache, 70% of the units infused crystalloids into the epidural space, whereas only 8.6% were in favour of an early prophylactic blood patch.
