among patients with chronic unrelieved pain, war veterans of eight years long iraq - iran war deserve especial attention. they not only suffer from severe intractable pain but also should bear some intangible consequences of unrelieved pain and severe disability. this perspective study reviews the outcome of implantation of intrathecal opioid pumps in these patients. ten war veterans (mean age ...

BACKGROUND Intrathecal opioid administration has been used widely in patients suffering from severe cancer pain that is not managed with conventional modalities. However, the potential serious neurological complications from the procedure and the side effects of intrathecal opioids have made many clinicians reluctant to employ continuous intrathecal analgesia as a first-line therapeutic option ...

Fluorescence under ultra-violet irradiation has been described by one of us as a criterion for the detection of Ps. pyocyanea on culture plates (Lowbury, 1951). In mixed cultures we have recently found colonies showing typical fluorescence which proved on subculture to be Bact. coli. The colonies of the subculture did not fluoresce. It was thought that colonies of these bacteria in the original...

intrathecal administration of midazolam has been reported to have antinociceptive action, and to be an effective analgesic agent. in this prospective double-blind study we aimed to evaluate the postoperative effects of intrathecal midazolam with lidocaine following perineal operation. forty patients were randomly allocated to two groups: 20 patients in the control group received 2 ml of 5% heav...

BACKGROUND Intrathecal administration of acetylcholinesterase inhibitors produces antinociception in both animals and humans, but their effect on diabetic neuropathic pain has not been studied. In the current study, we determined the antiallodynic effect of intrathecal injection of an acetylcholinesterase inhibitor, neostigmine, in a rat model of diabetic neuropathic pain. In addition, since ac...

BACKGROUND Nonsteroidal antiinflammatory drugs are commonly used to treat postoperative and chronic pain. Animal studies suggest that these drugs act, in part, by blocking prostaglandin production in the spinal cord. The authors tested intrathecal ketorolac in patients with chronic or postoperative pain. METHODS After approval of the institutional review board and the Food and Drug Administra...

The primary mode of action of local anesthetics is through sodium channel and axonal conduction blockade. Local anesthetics have also extensive effects on pre-synaptic calcium channels that must function to stimulate the release of neurotransmitters. Thus, interference with calcium channel conductance may enhance spinal anesthesia with local anesthetics. The present study was designed to invest...

BACKGROUND Although intrathecal clonidine produces pronounced analgesia, antinociceptive doses of intrathecal clonidine produce several side effects, including hypotension, bradycardia, and sedation. Intrathecal tizanidine, another alpha(2)-adrenergic agonist, has provided antinociception without producing pronounced hemodynamic changes in animal studies. However, it has been unclear whether an...
