Society for Vascular Surgery clinical practice guidelines of thoracic endovascular aortic repair for descending thoracic aortic aneurysms.

Thoracic aortic diseases, including disease of the descending thoracic aorta (DTA), are significant causes of death in the United States. Open repair of the DTA is a physiologically impactful operation with relatively high rates of mortality, paraplegia, and renal failure. Thoracic endovascular aortic repair (TEVAR) has revolutionized treatment of the DTA and has largely supplanted open repair because of lower morbidity and mortality. These Society for Vascular Surgery Practice Guidelines are applicable to the use of TEVAR for descending thoracic aortic aneurysm (TAA) as well as for other rarer pathologic processes of the DTA. Management of aortic dissections and traumatic injuries will be discussed in separate Society for Vascular Surgery documents. In general, there is a lack of high-quality evidence across all TAA diseases, highlighting the need for better comparative effectiveness research. Yet, large single-center experiences, administrative databases, and meta-analyses have consistently reported beneficial effects of TEVAR over open repair, especially in the setting of rupture. Many of the strongest recommendations from this guideline focus on imaging before, during, or after TEVAR and include the following: In patients considered at high risk for symptomatic TAA or acute aortic syndrome, we recommend urgent imaging, usually computed tomography angiography (CTA) because of its speed and ease of use for preoperative planning. Level of recommendation: Grade 1 (Strong), Quality of Evidence: B (Moderate). If TEVAR is being considered, we recommend fine-cut (≤0.25 mm) CTA of the entire aorta as well as of the iliac and femoral arteries. CTA of the head and neck is also needed to determine the anatomy of the vertebral arteries. Level of recommendation: Grade 1 (Strong), Quality of Evidence: A (High). We recommend routine use of three-dimensional centerline reconstruction software for accurate case planning and execution in TEVAR. Level of recommendation: Grade 1 (Strong), Quality of Evidence: B (Moderate). We recommend contrast-enhanced computed tomography scanning at 1 month and 12 months after TEVAR and then yearly for life, with consideration of more frequent imaging if an endoleak or other abnormality of concern is detected at 1 month. Level of recommendation: Grade 1 (Strong), Quality of Evidence: B (Moderate). Finally, based on our review, in patients who could undergo either technique (within the criteria of the device's instructions for use), we recommend TEVAR as the preferred approach to treat elective DTA aneurysms, given its reduced morbidity and length of stay as well as short-term mortality. Level of recommendation: Grade 1 (Strong), Quality of Evidence: A (High). Given the benefits of TEVAR, treatment using a minimally invasive approach is largely based on anatomic eligibility rather than on patient-specific factors, as is the case in open TAA repair. Thus, for isolated lesions of the DTA, TEVAR should be the primary method of repair in both the elective and emergent setting based on improved short-term and midterm mortality as well as decreased morbidity.

The North East Multispecialty Delphi Project - Collaboration Between Trainee Research Networks.

Trainee research collaborative networks have revolutionized how trainees participate in clinical research. Three North East of England trainee-led research groups, the Intensive Care and Anesthesia Research Network of North East Trainees (INCARNNET), the Northern Surgical Trainees Research Association (NOSTRA) in General Surgery and the Collaborative Orthopedic Research Network (CORNET) in Trauma and Orthopedics have joined, creating a multispecialty collaborative. This multispecialty collaborative undertook a two-phase research Delphi, between November 2017 and June 2018, to identify key research questions. This Delphi identified three high priority research questions common to the three specialties: what is the impact of diabetes control on perioperative outcomes, what factors affect theater efficiency, and how to prevent postoperative chest infection following emergency surgery? These research questions will be developed into collaborative projects. The Delphi also identified specialty-specific questions to be taken forward as research projects by each network.

High impact interventions to control infection.

High impact interventions can be undertaken to improve, and to monitor the effectiveness of, infection control procedures in emergency departments (EDs). Any member of a clinical team can lead on implementing these interventions, although motivating colleagues to take part is sometimes difficult. This article discusses non-compliance with infection control procedures and examines how ED staff can use high impact interventions.

Mechanical Ventilation in the Prehospital and Emergency Department Environment.

Patients who require mechanical ventilation in the prehospital and emergency department environments experience high mortality and are at high risk of ventilator-associated ventilator-induced lung injury and ARDS. In addition, little attention has been given in the literature, trainee education, or clinical emphasis to ventilator management in these patients. ARDS and ventilator-induced lung injury are time-sensitive disease processes that develop early in mechanical ventilation and could potentially be prevented with early lung-protective ventilation. Prehospital and emergency department ventilation, in general, is characterized by potentially injurious tidal volume, high FIO2 , and low PEEP. Recent literature highlights improved subjects outcomes in the setting of early lung-protective ventilation in both subjects with and those without ARDS. This review of the literature led us to recommend that lung-protective ventilation with avoidance of hyperoxia be the default goal ventilator strategy for all patients with prehospital and emergency department mechanical ventilation. This can be achieved by delivering low tidal volumes with stepwise, concurrent titration of FIO2 and PEEP to facilitate adequate oxygenation.

The preparedness of emergency medical services against occupationally acquired communicable diseases in the prehospital environment in South Africa.

BACKGROUND: Emergency medical care is performed in an uncontrolled environment and involves invasive procedures and life support measures. The performance of these duties places emergency care practitioners (ECPs) at risk of occupationally acquired injuries and communicable diseases. Although legislative guidelines exist for the protection of healthcare workers, little is known about the protective measures available for and utilised by ECPs in the pre-hospital environment in South Africa. OBJECTIVES: To review the availability and implementation of emergency medical services (EMS)-specific infection control policies and standard operating procedures in the pre-hospital environment. METHODS: Interviews with key informants were used to collect data concerning policies on communicable diseases and infection control in the EMS, the operational aspects of these policies, and educational programmes on communicable diseases and infection control for ECPs. RESULTS: There is no national policy on communicable diseases and infection control in EMS. Only KwaZulu-Natal, Eastern Cape and Gauteng have EMS-specific standard operating procedures for communicable diseases and infection control. Formal education and in-service training is limited. CONCLUSIONS: A national communicable disease and infection control policy specific to the EMS needs to be developed together with an accredited training module on communicable diseases and infection control for EMS in the pre-hospital environment.

Splinting versus casting of "torus" fractures to the distal radius in the paediatric patient presenting at the emergency department (ED): a literature review.

AIM: To compare outcomes regarding splinting versus casting of paediatric torus fractures in the ED with the aim of establishing the preferred treatment. METHODS: Evidence was collated using electronic databases; Pubmed, Ovid, Medline and Cochrane library. Search terms included [torus fractures; buckle fractures; splinting distal radius fractures; paediatric wrist fractures; paediatric forearm fractures/injuries; cast versus splint]. Searches identified papers published between 1984 and June 2008. RESULTS: The review demonstrated that children with removable splints preferred them to casts, in terms of improved physical functioning and lower pain scores reported after initial injury than those with casts. Children demonstrated this by using their wrists in the first week after injury to shower and bathe more easily. The cast group reported unscheduled visits to ED due to problems with the cast, such as discomfort or re-application of the cast from getting it wet. Using a splint will have considerable economic implications, money was found to be saved in terms of time and resource management. Radiographs taken at 4 weeks in both the cast and splint group confirmed that all fractures healed without significant change in alignment, suggesting that neither clinical nor radiographic follow-up is necessary for injury. CONCLUSION: Torus splints in all the studies were consistently better than plaster immobilisation in terms of clinical outcome, patient preference and cost, with the exceptions of young children or children with special needs who can easily remove the device. Splinting torus fractures may reduce cost, time and resource management if used instead of casting in the ED.
