Opioids are the most effective and widely used drugs in the treatment of severe pain. They act through G protein-coupled receptors. Four families of endogenous ligands (opioid peptides) are known. The standard exogenous opioid analgesic is morphine.…

BACKGROUND: No comprehensive review has been published to date, which provides information for nurses on pharmaceutical alternatives to morphine in palliative care. As nurses are often the health professional most involved with terminally ill…

BACKGROUND: Bisphosphonates form part of standard therapy for hypercalcemia and the prevention of skeletal events in some cancers. However, the role of bisphosphonates in pain relief for bony metastases remains uncertain. OBJECTIVES: To determine the…

Children and adolescents with recurrent or chronic pain and headache are a complex and heterogenous population. Patients are best served by multi-specialty, multidisciplinary teams to assess and create tailored, individualized pain treatment and…

We describe the successful use of methadone in the restoration of sedation and provision of analgesia in two morphine-tolerant, paediatric patients who had suffered significant thermal injuries and were undergoing mechanical ventilation. Both…

BACKGROUND: Codeine analgesia is wholly or mostly due to its metabolism to morphine by the cytochrome P450 enzyme CYP2D6, which shows significant genetic variation in activity. The aims of this study were to investigate genotype, phenotype and…

OBJECTIVE: Review and analyze the evidence base comprising methadone conversion methods and associated dosing ratios for the treatment of pain. DESIGN: Systematic review. METHODS: Clinical trials and retrospective analyses, case series, and case…

Development of analgesic tolerance and withdrawal-induced pain enhancement present serious difficulties for the use of opioids for pain control. Although neuronal mechanisms to account for these phenomena have been sought for many decades, their…

Traditionally, opioids have been administered as fixed doses at fixed dose intervals. This approach has been largely ineffective. Patient-controlled analgesia (PCA) and upgraded traditional approaches incorporating flexibility in dose size and dose…

Records on recovery after cholecystectomy of patients in a suburban Pennsylvania hospital between 1972 and 1981 were examined to determine whether assignment to a room with a window view of a natural setting might have restorative influences.…

Recently, patient controlled analgesia (PCA) has gained prominence in the treatment of pain for children suffering from vaso-occlusive crisis associated with sickle cell disease. Because there are several different regimens that can be used for PCA,…

The treatment of severe pain with opioids has thus far been limited by their unwanted central side effects. Recent research promises new approaches, including opioid analgesics acting outside the central nervous system, targeting of opioid…

OBJECTIVES: Professional societies, ethics institutes, and the courts have recommended principles to guide the care of children with life-threatening conditions; however, little is known about the degree to which pediatric care providers are aware of…

Patients with cancer sometimes are admitted to the emergency room due to severe pain. Despite the fact that morphine's hydrophilicity can delay its peak effects after intravenous administration up to 30 minutes, it is still the most commonly used…

The purpose of this study was to evaluate the need for pain medication and the adequacy or inadequacy of the analgesia achieved, in children with cancer who died while in terminal care. Of the 100 pediatric patients with cancer treated at the…

OBJECTIVE: Pain relief is still inadequate in many hospitalized patients, especially children in whom suboptimal use of analgesic drugs is still common. In the past 2 years, oral methadone has been used extensively in our institution for treating…

PURPOSE: Methadone is still regarded as a second line opioid for patients suffering from severe pain, and is rarely used in hospitalized patients. The infrequent use of methadone is probably due to its long plasma half-life that could lead to…

AIM: To assess the use of methadone in patients with cancer pain who fail to respond to increasing doses of other opioids or experience intolerable side-effects from them. METHOD: Inpatients of a specialist palliative care unit were titrated onto…

The opiate hypothesis maintains that patients engage in self-injurious behavior (SIB) either because they are partially analgesic (pathologically altered pain threshold) or because SIB supplies a "fix" for an addicted endogenous opiate system. The…

This fact fact will review sedation techniques.

Ingestions of opioid analgesics by children may lead to significant toxicity as a result of depression of the respiratory and central nervous systems. A review of the medical literature was performed to determine whether low doses of opioids are…

Over the last 5-10 years, there has been significant growth in the knowledge and strategies of pain management in children. Investigations are required to discern whether concomitant improvements in clinical practice have occurred. The purpose of…
