Randomized Controlled Trial Comparative StudyOpioid-induced respiratory effects: new data on buprenorphine.
When selecting the appropriate long-acting opioid to treat cancer pain, both analgesic efficacy and safety need consideration. Generally, opioids are well tolerated. However, of opioid-typical adverse events, respiratory depression is especially important because of the risk of a fatal outcome. ⋯ In conclusion, buprenorphine is more favourable compared with fentanyl in respect to ventilatory control. Buprenorphine causes limited respiratory depression with a ceiling effect at higher doses, while fentanyl causes dose-dependent respiratory depression with apnoea at high dose levels. In the rare instance of respiratory depression, reversal is possible with a sufficient and continuous infusion of naloxone.

Randomized Controlled Trial Clinical TrialSelf-administered nitrous oxide for the management of incident pain in terminally ill patients: a blinded case series.
The treatment of incident pain in terminally ill cancer patients receiving long-term opioid therapy remains a challenge. Self-administered inhaled nitrous oxide has been used for short-term analgesia in this setting, with mixed results. It is unclear whether nitrous oxide exhibits cross-tolerance with opioids, and there is the possibility of a strong placebo effect in previous unblinded reports. ⋯ The patient population was very heterogeneous with respect to disease, pain scores and concurrent treatments. Nitrous oxide was beneficial during incidents in five of seven patients; the remaining two patients reported an overall preference for the nitrous oxide day. We conclude that a trial of self-administered inhaled nitrous oxide should be considered in patients with difficult incident pain.

Randomized Controlled Trial Clinical TrialA randomized controlled trial of aromatherapy massage in a hospice setting.
Research suggests that patients with cancer, particularly in the palliative care setting, are increasingly using aromatherapy and massage. There is good evidence that these therapies may be helpful for anxiety reduction for short periods, but few studies have looked at the longer term effects. This study was designed to compare the effects of four-week courses of aromatherapy massage and massage alone on physical and psychological symptoms in patients with advanced cancer. ⋯ There were also statistically significant reductions in depression scores in the massage group. In this study of patients with advanced cancer, the addition of lavender essential oil did not appear to increase the beneficial effects of massage. Our results do suggest, however, that patients with high levels of psychological distress respond best to these therapies.

Randomized Controlled Trial Comparative Study Clinical TrialA randomized controlled trial of supplemental oxygen versus air in cancer patients with dyspnea.
The symptomatic benefits of oxygen in patients with cancer who have nonhypoxic dyspnea are not well defined. ⋯ Currently, the routine use of supplemental oxygen for dyspnea during exercise in this patient population cannot be recommended.
