ObjectiveTo evaluate the short-term efficacy and safety of methoxyflurane for the treatment of acute pain in patients presenting to an emergency department (ED) with minor trauma.MethodsSTOP! was a randomised, double-blind, multicentre, placebo-controlled study conducted at six sites in the UK. A total of 300 patients, 90 of whom were adolescent patients (age 12–17 years), were randomised 150:150 to receive either methoxyflurane via a Penthrox inhaler or placebo. The primary end point of the study was the change in pain intensity as measured using the visual analogue scale (VAS) from baseline to 5, 10, 15 and 20 min after the start of study drug inhalation. Patients were supplied with one inhaler containing 3 mL methoxyflurane or 5 mL placebo after enrolment and initial assessments. Age group (adolescent/adult) and baseline VAS score were controlled for in the statistical analyses.ResultsA total of 149 patients received methoxyflurane, and 149 patients received placebo. Demographic and baseline characteristics were comparable between the groups. Methoxyflurane reduced pain severity significantly more than placebo (p<0.0001) at all time points tested, with the greatest estimated treatment effect of −18.5 mm (adjusted change from baseline) seen at 15 min after the start of treatment. Methoxyflurane was well tolerated, with the majority of adverse reactions being mild, transient and in line with anticipated pharmacological action.ConclusionThe results of this study suggest that methoxyflurane administered via the Penthrox inhaler is an efficacious, safe, and rapidly acting analgesic.Trial registration number:NCT01420159.

This is the first article in a three-part series detailing the lessons identified during the NHS England clinical debrief meetings which followed the response to the 2017 Manchester and London terrorist incidents. It covers the prehospital phase including the overall key learning points, timeline information, scene challenges, resource utilisation, triage, distribution and helicopter emergency medical service feedback.

The provision of medical care during the reception and definitive care phases of a terrorist incident will likely take place in designated receiving hospitals such as Major Trauma Centres. There is a need for an enhanced capability in such units to receive, initially manage and hold casualties with more serious injuries. Also, even less severely injured casualties may require significant time and clinical input such as risk management in potential bloodborne viruses.The distribution of casualties from the incident scene requires advance consideration of the injury pattern and regional network organisation of specialist services, such as maxillofacial, neurosurgery or severe burns care. Paediatric centres are also more sparsely distributed and often only in large city networks which represents a significant challenge for planners and responders in other regions. An effective response relies on a coordinated multidisciplinary approach including emergency and front-of-house teams, surgical, medical and clinical support services.

This is the third paper in a three-part series detailing the lessons identified during the National Health Service (NHS) England clinical debrief meetings which followed the response to the 2017 Manchester and London terrorist incidents. It covers the postincident and recovery phases including rehabilitation, bereavement support, psychological support, network and regional lessons, NHS communications and supply organisations. It also summarises the military application of these lessons and outlines the next steps for further development.

IntroductionThe WHO Constitution enshrines ‘…the highest attainable standard of health as a fundamental right of every human being.’ Strengthening delivery of health services confers benefits to individuals, families and communities, and can improve national and regional stability and security. In attempting to build international healthcare capability, UK Defence Medical Services (DMS) assets can contribute to the development of healthcare within overseas nations in a process that is known as Defence Healthcare Engagement (DHE).MethodsIn the first bespoke DMS DHE tasking, a team of 12 DMS nurses and doctors deployed to a 1000-bedded urban hospital in a partner nation and worked alongside indigenous healthcare workers (doctors, nurses and paramedical staff) during April and May 2016. The DMS nurses focused on nursing hygiene skills by demonstrations of best practice and DMS care standards, clinical leadership and female empowerment. A Quality Improvement Programme was initiated that centred on hand hygiene (HH) compliance before and after patient contact, and the introduction of peripheral cannula care and surveillance.ResultsAfter a brief induction on the ward, it was apparent that compliance with HH was poor. Peripheral cannulas were secured with adhesive zinc oxide tape and no active surveillance process (such as venous infusion phlebitis (VIP) scoring) was in place. After intensive education and training, initial week-long audits were undertaken and repeated after a further 2 weeks of training and coworking. In the second audit cycle, HH compliance had increased to 69% and VIP scoring compliance to 99%. In the final audit cycle, it was noted that nursing compliance with HH (75/98: 77%) was significantly higher than the doctors’ HH compliance (76/200: 38%); p<0.0001.ConclusionsDHE is a long-term collaborative process based on the establishment and development of comprehensive relationships that can help transform indigenous healthcare services towards patient-centred systems with a focus on safety and quality of care. Short deployments to allow clinical immersion of UK healthcare workers within indigenous teams can have an immediate impact. Coworking is a powerful method of demonstrating standards of care and empowering staff to institute transformative change. A multidisciplinary group of Quality Improvement Champions has been identified and a Hospital Oversight Committee established, which will offer the prospect of longer term sustainability and development.

This study has shown that short-term survival from TCA in a military population is 10.6%. With appropriate and aggressive early management, although unlikely, survival is still potentially possible in military patients who suffer traumatic cardiac arrest.

Acute knee injuries are common presentations that frequently occur during sporting activities and can result in permanent disability. However, they often result in a single visit, seldom receive surgical intervention and, in the main, are cared for entirely by General Practitioners or Emergency Department physicians. Thorough clinical assessment and appropriate early treatment at the primary presentation is vital in order to offer the best chance of maximal functional recovery and to minimize long-term disability. This requires a sound knowledge of basic knee anatomy, careful assessment of the mechanism of injury, detection and consideration of physical ndings and the results of adjunctive investigations. This article aims to give a comprehensive review of the examination, investigation and early treatment of acute knee injuries at the primary presentation. In addition, comments on important epidemiological and aetiological factors and a brief description of basic knee anatomy are also provided.
