Comparative Study
Comparison of CT head interpretation between emergency physicians and neuroradiologists.
Cranial computed tomography (CT) of the head is widely used in the emergency department 24 h a day. We compared the accuracy of CT head interpretation between staff emergency physicians (EPs) and neuroradiologists. We conducted a health records review of patients who required head CT in the emergency department. ⋯ The weighted kappa for agreement was 0.83 (95% confidence interval 0.76-0.90). None of these patients had adverse outcomes related to EP misinterpretation of the CT head. In conclusion, clinically important findings on CT head are not commonly missed by our EPs and patients rarely have inappropriate disposition.

This descriptive study presents availability and content of acute pain protocols in emergency departments (EDs) in The Netherlands. Current acute pain protocols were collected and an a priori list of questions was used for analysis. Findings were compared with current international standards. ⋯ Acute pain protocols are lacking in many EDs. Most protocols did not apply current standards. We exposed an area with space for leadership.

Review Case Reports
A meta-analysis on the utility of peripheral venous blood gas analyses in exacerbations of chronic obstructive pulmonary disease in the emergency department.
The objective of this case-based review is to identify and summarize the relevant evidence for the clinical utility of peripheral venous blood gas (pVBG) analyses in patients with acute exacerbations of chronic obstructive pulmonary disease (COPD) treated in the emergency department. Relevant studies were identified using the Cochrane Library, Medline, Embase, and CINAHL databases and by hand searching of references of published articles. Included studies were prospective trials comparing arterial and pVBG results in patients with COPD or respiratory distress that reported at least average differences and/or limits of agreement between the two results in English. ⋯ No studies investigated the role of pVBG analysis in treatment alteration or clinical outcomes. Available evidence suggests that there is good agreement for pH and HCO3 values between arterial and pVBG results in patients with COPD, but not for pO2 or pCO2. Widespread clinical use is limited because of the lack of validation studies on clinical outcomes.

Multicenter Study
Prehospital ultrasound in emergency medicine: incidence, feasibility, indications and diagnoses.
Sonography is an established diagnostic procedure in hospitals, but is not routinely used in prehospital emergency medicine. Several studies have addressed the use of ultrasound during helicopter flights and in emergency rooms, few in prehospital settings, but most focused on abdominal blunt trauma. Several case reports describe crucial decisions distinguished by ultrasound. ⋯ Ultrasound is the only imaging modality and a useful diagnostic tool in prehospital emergency medicine. Helpful information can be provided in at least one of six cases (or even more) in a trauma-dominated collective. Examination time is short; it will not significantly delay medical care. Ultrasound examination could improve triage in cases of more than one patient in disaster medicine, but further studies are necessary.

Ultrasound (US) has been used for in-hospital evaluation of the trauma victim for many years. The outcome in severely injured patients remains heavily influenced by initial life support and early care, as time plays a major role. Development of handheld, battery-powered, low-weight US machines has created the possibility of bringing US to the prehospital setting, thus gaining a potential for early diagnosis and treatment. ⋯ Several studies in this review showed that prehospital US is feasible and that the procedure is highly reliable in detection of haemoperitoneum or haemopericardium compared with the low accuracy of physical examination and haemodynamic measurements. An early diagnosis will provide the prehospital physician with the knowledge to prioritize the relevant initial treatment and to choose the closest appropriate hospital and transportation form. There is currently no evidence in the literature that prehospital US of the abdomen or thorax improves treatment of trauma patients.
