Case ReportsContinuous intrathecal fentanyl infusion for postoperative analgesia.
Following inadvertent dural puncture during epidural catheter placement, a 20 gauge polyethylene catheter was placed in the intrathecal space, and continuous spinal anesthesia with hyperbaric bupivacaine was administered intraoperatively to supplement general anesthesia. Following surgery, a continuous intrathecal fentanyl infusion (0.2 mcg/kg/hr) was administered to provide postoperative analgesia. The child was awake and comfortable throughout this time and required no supplemental analgesic agents. Although epidural catheters are still our preferred method of analgesia, intrathecal fentanyl infusion is one alternative when inadvertent dural puncture occurs.

Validation of World Health Organization guidelines for cancer pain relief during the last days and hours of life.
The efficacy of the World Health Organization's guidelines for cancer pain relief was examined in 401 dying patients. At the time of death, only 3% of the patients experienced severe or very severe pain; whereas 52% had no pain at all, 24% experienced only mild or moderate pain, and 20% were unable to rate their pain intensity. Analgesic drugs were the mainstay of therapy during the last 24 hr of life, being administered by mouth in 47% and parenterally in 44% of the patients. ⋯ Additional adjuvant drugs to treat special types of pain or other symptoms were prescribed in 90% of the patients. Nonpharmacological measures, such as radiotherapy, nerve blocks or neurosurgery played only a very minor role at this stage of the disease. This study shows that cancer pain can be treated satisfactorily until death.

Clinical Trial Controlled Clinical TrialA clinical study on the use of codeine, oxycodone, dextropropoxyphene, buprenorphine, and pentazocine in cancer pain.
The authors report a prospective study on 944 cancer pain patients treated with one of the following opioids: codeine, oxycodone, dextropropoxyphene, buprenorphine, and pentazocine. Level of analgesia, duration of treatment, side effects, and drop out were evaluated for each drug. ⋯ Pentazocine did not show an evident analgesic effect during the first 2 wk of treatment. The other opioids were found to be valid therapeutic instruments for chronic cancer pain control in a limited number of patients.

Case ReportsPiriformis muscle syndrome: an underdiagnosed cause of sciatica.
This is a retrospective review of 26 patients with sciatica due to the piriformis muscle syndrome. Most patients had pain in the buttock area and sciatica, and most experienced difficulty walking and sitting, even for short periods of time. Reproduction of the sciatica upon deep palpation, either by gluteal or rectal route, was diagnostic. ⋯ Other signs were helpful but not consistent. After the appropriate diagnosis, the treatment was relatively easy and rewarding. This study emphasizes that the diagnosis of piriformis muscle syndrome is clinical; without the appropriate clinical examination, it can be easily misdiagnosed.

This survey compares costs of two commonly utilized implantable narcotic delivery systems. The systems are classified into type-I (exteriorized system using the DuPen epidural catheter) and type-II (implanted system using the Synchromed pump). Costs were analyzed by reviewing actual patient hospital financial service records and Homecare vendor quotations. From the perspective of cost analysis alone, we conclude that savings accrue when patients requiring treatment beyond 3 months duration are managed with a type-II implanted system compared with a type-I system with an external pump.
