BACKGROUND AND PURPOSE Spinal cord stimulation is a well-known treatment of rigorously selected failed-back surgery syndrome patients. Efficacy levels over 50% of pain relief have been reported in long-term studies. The objective of this multicenter prospective evaluation was to analyze the cost to benefit ratio of spinal cord stimulation treatment for(More)
The use of intraspinal narcotics has been widely accepted as pain relief treatment for intractable cancer pain. Intraspinal low doses of morphine induce a potent selective long lasting analgesia. To avoid repetitive lumbar puncture, a drug delivery device was surgically implanted in 41 patients. The surgical procedure is described. The mean amount of(More)
The technique is of interest in deep bone pain in terminal metastasized cancer, but early relapses often occur. The hypoalgesia or analgesia obtained does not seem to result from endocrine mechanisms only, nor from the release of endogeneous opioid peptides. This neuroadenolysis seems to interfere in the pain pattern either through still unknown(More)
Low dose morphine epidurals (0.5 to 4 mg) provide a good way of controlling either per or postoperative pain (210 cases) or chronic, somatic, intractable pain (282 cases). Selective and metameric medullar hypoalgesia is induced at a level which varies with the level of injection. There is an acquired tolerance which restricts the use of such injections to(More)
The authors report their experience with 35 guanethidine intravenous local injections in algodystrophic and neurotrophic syndromes. Although excellent results are obtained in post-traumatic algodystrophies which are treated early, they are less remarkable in long standing sequelae due to injuries of the nervous system, and where, at best, only an antalgic(More)
Pain due to bone metastasis in hormonodependent cancer (of the breast or the prostates more particularly) can be relieved by surgery directed at the endocrinic system. The most efficient techniques are hypophysectomies and hypophysiolysis (or neuroadenolysis). The intrasellar injection of alcohol through the transnasal-transsphenoidal route is a fairly(More)
Twenty five healthy pregnant women received an epidural injection (at levels varying from T11-T12 to L3-L4) of morphine (2 or 3 mg in 10 ml of saline solution 9 p. thousand) in order to achieve pain relief for delivery. The degree of dilation never exceeded 5 cm at time of injection. Pain level decreased in 22 cases (88 p. cent) but only 16 women (64 p.(More)
