title: [Treatment of pain with peridural administration of opioids].
abstract: The advantages and disadvantages associated with epidural opioids require careful selection of the opioid and its dosage. There is presently no ideal opioid available for epidural use. Comparative pharmacokinetic data help to select the appropriate epidural opioid. Morphine (provided it is given in small doses and volumes) is very appropriate for epidural pain treatment, especially for longer periods of treatment, due to excellent analgesia and very low systemic morphine concentrations. The faster onset of analgesia with epidural pethidine, alfentanil und fentanyl make these opioids recommendable. However, due to the increased risk of respiratory depression during continuous treatment, these drugs should not be given over extended periods. Epidural administration of methadone, sufentanil und buprenorphine cannot be recommended since the advantages over systemic use do not outweigh the risks. Epidural tramadol may be useful in clinical routine, if opioids are not available and supervision of the patient is not guaranteed, because tramadol is not restricted by law and has a low potential for central depressive effects. The safety of the patients should be paramount. If patients are harmed by inappropriate opioids or dose regimens this will discredit a valuable for treating postoperative pain. Postoperative epidural dosages should be as low as possible and be titrated to the patient's individual needs for analgesia. Epidural morphine treatment is an alternative to step 4 of the WHO treatment regimen for patients with intractable pain or those suffering from systemic opioid side effects. Careful selection of patients helps to increase successful treatment. If implantable devices (ports or pumps, according to the life expectancy) are employed, the intrathecal route of administration is preferable to the epidural route, as the latter has a 10 times higher morphine dose requirement.
