This month’s update comes from the Emergency Department at Northern General Hospital, Sheffield. We used a multimodal search strategy, drawing on free open-access medical education resources and literature searches. We identified the five most interesting and relevant papers (decided by consensus) and highlight the main findings, key limitations and clinical bottom line for each paper.

  • Worth a peek—interesting, but not yet ready for prime time.

  • Head turner—new concepts.

  • Game changer—this paper could/should change practice.

A non-inferiority randomised controlled trial comparing nebulised ketamine to intravenous morphine for older adults in the emergency department with acute musculoskeletal pain. Kampan et al

Topic: Analgesia

Outcome rating: Head turner

Inadequate management of acute pain in older adults contributes to adverse outcomes including decline in mobility, cognition and mood. Effective analgesia is important but must consider the physiological changes associated with ageing that affects pharmacokinetics. Although opioids are effective, they do have undesirable effects.

This study compared the analgesic efficacy and safety of nebulised ketamine to intravenous morphine in older patients.1 This non-inferiority, double-blind, randomised control trial was carried out in a tertiary centre in Thailand. Final analysis included 92 patients aged ≥65 years presenting to the emergency department with acute, moderate-to-severe musculoskeletal pain, including superficial injuries and limb fractures. An 11-point numeric rating scale (NRS) was used to measure pain levels.

There was no significant difference in mean NRS between the nebulised ketamine and intravenous morphine groups (5.2 vs 5.7) at 30 min. The comparative mean difference in the NRS change from baseline between nebulised ketamine and intravenous morphine was 0.2 (95% CI −0.49 to 0.89), which did not exceed the non-inferiority margin of 1.3. Results were comparable at other time points between 15 min and 120 min. There was also no significant difference between the two groups in use of rescue therapy or vital signs. Side effects, particularly nausea and dizziness, …
