Audit of neural blockade for palliative care patients in an acute unit

Opioid poorly-responsive cancer pain. Part 3. Clinical strategies to improve opioid responsiveness

Some pain syndromes may be difficult to treat due to a poor response to opioids. This situation demands a range of alternative measures, including the use of adjuvant drugs with independent effects, such as antidepressants, sodium channel-blocking agents, steroids and anti-inflammatory drugs (NSAIDs); drugs that reduce opioid side effects; and drugs that enhance analgesia produced by opioids, such as N-methyl-D-aspartate (NMDA) antagonists, calcium channel antagonists, and clonidine. Other approaches, including opioid trials, neural blockade when necessary, and psychological interventions, also may be useful.

The use of interpleural analgesia using bupivacaine for pain relief in advanced cancer

The use of interpleural analgesia is described in six patients with a variety of advanced malignancies suffering from pain uncontrolled by opioids. The benefits and complications of the technique are discussed including management of the catheters at home and the measurement of plasma bupivacaine concentrations. Interpleural analgesia can provide good analgesia in a small, selected population of patients with otherwise uncontrolled pain of malignant origin.

Assessing the effectiveness of a hospital palliative care team

A prospective study was carried out of 125 hospital inpatients with malignant disease, referred to the King's College Hospital advisory palliative care team. A palliative care assessment (PACA) tool was developed in order to assess the outcome of interventions made within two weeks of referral with regard to: symptom control, change in the patients' and their relatives' insight regarding diagnosis and prognosis, and facilitation of patient placement. Reliability was assessed by cross-observer analysis, and validity by comparison with data obtained using the McCorckle symptom distress scale in a separate group of hospice inpatients. At initial assessment, the commonest symptom was pain, as reported by 74% of patients. One-third of the patients were unsure of their diagnosis and placement had not been decided in 61%. In total, the team undertook 245 pharmacological interventions for symptom control, 165 interventions regarding insight and 114 interventions concerning placement. Analysis of the data showed statistically significant improvements in pain (p < 0.001), nausea (p < 0.009), insomnia (p < 0.004), anorexia (p < 0.001) and constipation (p < 0.02). Discussion regarding diagnosis significantly changed the insight of patients (p < 0.001) and relatives (p < 0.02). Appropriate placement was assisted by interventions undertaken by the team. This study shows that a hospital palliative care team is effective at improving symptom control, facilitates understanding of the diagnosis and prognosis, and contributes to the appropriate placement of patients.
