Phantom pain may occur in up to 85% of patients after limb amputation. Although the pathophysiology of postamputation phantom pain is not well understood, it seems to be produced by a complex multifactorial interaction between the peripheral, sympathetic, and central nervous systems. ⋯ Among the pharmacological agents proved effective against phantom pain are beta-blockers, tricyclic antidepressants, and anticonvulsants. Surgical management includes peripheral nerve stimulation, thermocontrolled coagulation of the spinal cord, spinal cord stimulation, transcutaneous nerve stimulation, and stereotactic deep brain stimulation.

Randomized Controlled Trial Comparative Study Clinical Trial
Double-blind comparison of the efficacy of extradural diamorphine, extradural phenoperidine and i.m. diamorphine following caesarean section.
A randomized, double-blind study of the efficacy, duration of action and side effects of three analgesic regimens following Caesarean section is described. Patients received i.m. diamorphine 5 mg, extradural phenoperidine 2 mg or extradural diamorphine 5 mg. Analgesia was of rapid onset in all groups, as judged by reductions in linear analogue pain scores and rank pain scores. ⋯ Itching was reported on direct questioning by 50% of patients in the extradural groups. No serious side effects were reported. Factors affecting the disposition of extradurally administered diamorphine are discussed.

ReviewAnalgesic drug therapy in cancer pain: principles and practice.
Drug therapy represents the mainstay of treatment for patients with cancer pain. Non-narcotic, narcotic, and adjuvant analgesics are the commonly used agents. The choice of a specific analgesic drug regimen is dependent on the type of pain and its severity, and the drug must be titrated to the individual needs of the patient.

Randomized Controlled Trial Clinical Trial
Intraoperative bupivacaine during outpatient hernia repair in children: a randomized double blind trial.
Postoperative pain is a major problem following surgery in the ambulatory child. A study was undertaken to test the effect of intraoperative bupivacaine on postoperative pain in children undergoing outpatient hernia repair. Ninety-nine children aged 1 to 7 years underwent outpatient inguinal herniorrhaphy under general anesthesia. ⋯ Activity level at home on the day of surgery did not differ significantly between groups, but activity level over the following 48 hours was higher in group 1 (P less than .05). The two groups were similar with respect to all other parameters. We conclude that intraoperative bupivacaine decreases post-operative pain and analgesic use, and promotes early ambulation in children undergoing hernia repair.
