Review Comparative StudyEpidural and intrathecal opiates in obstetrics.
The use of epidural and intrathecal opiates in obstetrics is reviewed. Opiate receptors in the substantia gelatinosa of the spinal cord appear to be the main site of drug action after both epidural and intrathecal modes of drug administration. However, an additional systemic effect for this selective spinal analgesia cannot be excluded, especially after epidural drug administration. ⋯ After intrathecal injection of opiates, there was a strong analgesic action during delivery, but an unacceptable amount of side effects prevents their routine use. In post-cesarean patients, epidurally administered opiates are quite effective analgesics, but they still have one serious unwanted effect: respiratory depression of delayed onset. Thus, in routine obstetric practice, epidural or intrathecal opiates play only a limited role.

Many critically ill patients suffer pain which can produce by itself undesirable effects. Consequently, pain must be carefully prevented, or at least, treated early and effectively. ⋯ Computer-assisted intravenous "on demand" analgesia with Fentanyl can also be used. When pain coverage is required during transient events such as active physiotherapy or dressing changes, additional intravenous of a narcotic (1-2 mg morphine e.g.) or inhalation of nitrous oxide with oxygen are usually effective.
