A consecutive series of 100 microneurosurgical revision operations on lumbar discs has been evaluated in a prospective and randomized clinical trial analyzing the influence of dexamethasone on postoperative clinical outcome. ⋯ After revision operations on lumbar discs, corticosteroids are a helpful adjuvant drug for relief of lumbar or radicular pain, but they do not significantly improve the final clinical outcome.

In this case report, we describe continuous subcutaneous infusion of opiates as PCAO (patient controlled analgesia in outpatients) in one patient with metastatic carcinoma of the rectum (liver and bone metastases, partial bowel obstruction) with severe cancer pain and vomiting in the terminal phase. The parenteral administration of opioids extended over 58 days. The infusion was powered by an external portable clockwork-driven syringe pump (Perfusor M, Braun Medical/Germany). ⋯ When he received outpatient radiation therapy the patient needed extra injection doses of up to 360 mg morphine a day. The PCAO procedure by continuous subcutaneous infusion with opiates is a safe and efficient method of pain management for outpatient patients suffering from severe cancer pain and intractable nausea in the terminal phase. Its validity has also been proven especially for radiation treatment of bone metastases.
