Introduction. Intrathecal octreotide has been considered an alternative to opioids in chronic infusion for pain. Octreotide is an analog of the growth hormone sandostatin. Previous work has shown the drug to be efficacious in cancer patients who had failed intrathecal opioids. ⋯ The Saint Francis Hospital IRB and FDA approved the ongoing use of intrathecal octreotide for research. Conclusions. Intrathecal octreotide, at doses as high as 20 µg/hr, appeared to be as safe as saline when given as a continuous intrathecal infusion. Further work is needed on dose-range analysis and efficacy.

Meralgia paresthetica is a clinical syndrome of pain, dysesthesia or both, in the anterolateral thigh. It is associated with an entrapment mononeuropathy of the lateral femoral cutaneous nerve. Diagnosis of meralgia paresthetica is typically made clinically and is based on the characteristic location of pain or dysesthesia, sensory abnormality on exam, and absence of any other neurological abnormality in the leg. The majority of patients with meralgia paresthetica respond well to conservative treatment. ⋯ An implanted spinal cord stimulator may be an ideal treatment for intractable meralgia paresthetica after conservative treatments have failed because it is not destructive and can always be explanted without significant permanent adverse effects.

Multiple studies have documented the incidence of illicit drug use and abuse of opioids. Over the years, several hypotheses have been proposed. Short-acting opioids such as hydrocodone are generally considered to predispose patients to poor pain management, dependency, misuse, or abuse; whereas long-acting opioids such as methadone are thought to provide sustained pain management without dependency or abuse. ⋯ There were no significant differences as to illicit drug use and/or misuse of opioids in patients treated with hydrocodone or methadone. These findings suggest that the use of a long acting opioid formulation by patients with chronic pain does not reduce the risk of drug abuse or improve compliance with medical therapy.

Despite preclinical evidence suggesting a synergistic interaction between ketamine and opioids promoting analgesia, several clinical trials have not identified dosing regimens capable of eliciting a benefit in the co-administration of ketamine with opioids. ⋯ A serum concentration of ketamine that did not alter indices of sedation potentiated the antinociceptive effect of fentanyl. This potentiation of antinociception occurred without an increase in sedation suggesting that low steady doses of ketamine (30-120 ng/ml) might be combined with mu opioid agonists to improve their analgesic effect in a clinical setting.
