We aimed to determine the value of sidestream end-tidal carbon dioxide (SS-ETCO2) measurement in patients with chronic obstructive pulmonary disease (COPD) in the emergency department. Cross-sectional associations between ETCO2 and PaCO2 were examined in the study. This prospective cross-sectional study has been carried out over a 3-month period in a tertiary care university hospital emergency department with an annual census of 75 000 visits. ⋯ Mean arterial PCO2 levels were 43.24±14.73 and mean ETCO2 levels were 34.23±10.86 mmHg. Agreement between PCO2 and ETCO2 measurements was 8.4 mmHg and a precision of 11.1 mmHg. As there is only a moderate correlation between PCO2 and ETCO2 levels in COPD patients, ETCO2 measurement should not be considered as a part of the decision-making process to predict PaCO2 level in COPD patients.

We wanted to identify incidents that led or could have led to patient harm during prehospital cardiopulmonary resuscitation. A nationwide anonymous and Internet-based critical incident reporting system gave the data. During a 4-year period we received 548 reports of which 74 occurred during cardiopulmonary resuscitation. ⋯ In most cases, prevention can be accomplished by simple strategies with the Poka-Yoke technique. Insufficient training of emergency medical service physicians in Germany requires special attention. The critical incident reports raise concerns regarding the level of expertize provided by emergency medical service doctors.

The interobserver variability of capillary refill time (CRT) has been questioned. Earlier studies of interobserver variability of CRT have been on a large number of patients but with few observers. The objective of our study was to investigate how a large group of nurses and nurse assistants would grade CRT. ⋯ This is the largest interobserver study of CRT when looking at the number of observers. We found an only moderate agreement for the exact value of CRT and a moderate agreement for normality. We believe that CRT should be used with caution in clinical practice.

The aim of our study was to determine the usefulness of pneumococcal urinary antigen (UA) collected in the emergency department (ED) for the microbiologic diagnosis of community-acquired pneumonia (CAP) in HIV patients and to compare it with other diagnostic tests. Prospective study from 1 January 2007 to 31 December 2008 included HIV-infected patients admitted at the ED with respiratory symptoms and who were diagnosed of CAP. UA, two blood cultures and sputum sample for culture determination were collected from every patient. ⋯ The statistical analysis showed that the test with best performance was the UA, both in relation to blood and sputum cultures (P<0.05). Two patients died during hospitalization (series mortality of 3%). In conclusion, given its good diagnostic performance, UA should be requested in the ED for the aetiological diagnosis of CAP.

The diagnosis of patients with acute dyspnoea is challenging, as clinical history and physical examination are often nondiagnostic and inaccurate. Consequently, clinicians often rely on the results of chest radiography (CXR) to determine the initial intervention and guide further treatment. ⋯ US-JVD is a sensitive test for identifying pulmonary oedema on CXR in dyspnoeic patients with suspected congestive heart failure.
