Randomized Controlled Trial Clinical Trial
Efficacy of continuous epidural analgesia and the implications for patient care in the early postoperative phase.
Management of postoperative pain has been shown to be inadequately controlled, and, in fact, can have significant deleterious effects on a patient's early postoperative recovery. Continuous epidural analgesia has recently been used to control postoperative pain. This mode of analgesia controls postoperative pain without the delays inherent in the PRN administration of systemic narcotics. ⋯ The results of this study showed that the level of pain relief and recovery of postoperative function was superior to that provided by the more widely used (PRN) systemic administration of narcotics. With the exception of the report of back pain by patients receiving the normal saline epidural solution, complications did not occur in a significantly greater proportion when using the epidural route. Although some nursing care problems were identified, patients who received epidural analgesia were able to be cared for on general care units with no adverse effects reported.

Chronic epidural administration of narcotics and/or local anesthetics is sometimes required in those few patients where utilization of systemic narcotics and appropriate adjuvant medications is unsuccessful in controlling intractable cancer pain. The Du Pen epidural catheter (Davol, Inc.) a silicone-based tunneled catheter modeled after the Hickman central venous catheter, has provided a safe, reliable means of long-term administration of drugs to the epidural space in over 400 patients to date. ⋯ Follow-up care of patients receiving epidural narcotic with or without local anesthetic can be accomplished by a trained home cae team. Successful epidural pain management requires thorough patient and caregiver education, frequent pain assessment, and monitoring of side effects, with close collaboration between patient/family, pharmacist, home care nurse, and physician.

Review[Urinary retention in connection with postoperative pain treatment with epidural opioids].
The incidence of retention of urine in cases of postoperative epidural opioid analgesia varies from 15% to 90%. The extent to which this phenomenon depends upon the dosage employed has not been elucidated. The cause of postoperative retention of urine (PU) is probably a combination of the central and peripheral effect of the opiate involving altered autonomic activity. ⋯ Carbacholine is not effective in the treatment of postoperative retention of urine. In animal experimental studies, kappa-receptor agonists have an analgesic effect without urodynamic side-effects but no clinical trials on man have hitherto been undertaken. When postoperative retention of urine occurs after epidural opioid treatment, clean intermittent catheterization or introduction of a thin suprapubic catheter are recommended.

Indices of vagal and sympathetic activity were studied in 30 elderly males, to elucidate their possible roles in causing hypotension during spinal analgesia. The technique of spinal analgesia and the regimen of intravenous fluids were standardised. An index of vagal activity was derived from the degree of heart rate variation (successive RR interval change) on ECG recordings. ⋯ There was no correlation between vagal activity and the degree of hypotension. The depression of skin conductance responses was not correlated with the degree of hypotension nor with vagal activity. Vagal efferent activity, measured at the heart, does not seem to play a causative role in hypotension occurring during spinal analgesia.
