Emergency ultrasound has established itself as a key procedure of primary diagnostic work-up for blunt abdominal and multiple trauma. However, in a systematic review published in 2001 ultrasonography turned out to provide an unexpectedly low sensitivity. We conducted an update of this analysis to investigate if test characteristics will be maintained including recent studies. ⋯ In pediatric trauma, ultrasound showed even worse test characteristics (negative LR = 0.43). Thus, in case of a 35% prevalence, the post-test probability has to estimated at 19%. Emergency ultrasound provides high specificity but insufficient sensitivity to reliably rule out intraabdominal injury.

Meta Analysis
[Can selective decontamination of the digestive tract as a routine procedure on intensive care units be recommended?].
After giving an overview on the epidemiological and microecological background, the applicable drugs, and the necessary microbiological surveillance for Selective Decontamination of the Digestive tract (SDD), the results of 2 new metaanalyses of 22 and 25 individual randomized studies are discussed. A 50%-reduction of the pneumonia incidence results in an only marginal reduction of the mortality rate in the subgroup of topically plus for the first few days systemically treated patients in mixed intensive care units. ⋯ The chance and the need to confirm a mortality benefit in multicentre trials enrolling large numbers of homogeneous surgical patients are explained. At the present time, SDD as a routine can not (yet) be recommended.
