Effective pain control is essential for the management of patients with cancer. About 70-80 percent of patients with cancer present in an advanced stage of disease. Patients with advanced cancer frequently experience intractable pain, with diverse symptoms that can make daily living impossible and affect the quality of life. ⋯ Nearly 89.6 percent patients had good pain relief with Visual Analogue Scale score less than 3. These promising results were achieved by careful patient assessment, close liaison with clinicians from other specialties, and using a variety of analgesic regimen including oral analgesics, anesthetic procedures, psychological interventions, and supportive care. However, the main stay of treatment was oral analgesics, following the principles of World Health Organization ladder, with continuing follow-up.

Randomized Controlled Trial
Balanced anesthesia with remifentanil and desflurane: clinical considerations for dose adjustment in adults.
The intraoperative combination of volatile anesthetics with opioids is a well-accepted technique because of its hemodynamic stability and side effects. This study in adults was designed to determine the pharmacodynamic interactions between different dosages of remifentanil and desflurane in response to skin incision. ⋯ Remifentanil reduces in a dose-dependent manner the desflurane requirements for skin incision without increasing recovery time. An infusion rate higher than 0.1 microg/kg/min results in a significantly decreased heart rate.

Intrathecal drug delivery (ITDD) has been an option for the management of persistent pain since the 1980s. The discovery of opioid receptors in the central nervous system was the impetus for early attempts to deliver opioids intraspinally. ⋯ However, there is also some evidence for the use of ITDD in those with noncancer pain. This review presents options for ITDD, available drugs, evidence for efficacy, principles of patient selection, and problems with the intrathecal route.

Review Case Reports
Edema caused by continuous epidural hydromorphone infusion: a case report and review of the literature.
Intraspinal drug delivery (IDD) therapy has been increasingly employed in patients with intractable, nonmalignant pain. Before implantation of permanent intraspinal pump, an intraspinal opioid screening trial is conducted to demonstrate the efficacy. The patient-controlled continuous epidural opioid infusion trail, performed in an outpatient setting, is widely accepted by many interventional pain specialists. ⋯ Edema may occur and persist during epidural hydromorphone infusion. This report represents the first case report, to the best of our knowledge, describing severe edema in a patient on continuous epidural hydromorphone administration during an outpatient epidural infusion trial.
