Comparative Study
Testing the validity of the ATLS classification of hypovolaemic shock.
The Advanced Trauma Life Support system classifies the severity of shock. The aim of this study is to test the validity of this classification. ⋯ In trauma patients there is an inter-relationship between derangements of HR, SBP, RR and GCS but not to the same degree as that suggested by the ATLS classification of shock.

Occult pneumothorax (OPTX) is defined as a pneumothorax seen on computed tomography but not apparent on supine plain radiography. Though increasingly common, the acute management of OPTX after trauma remains controversial. This evidence-based review evaluates the existing evidence regarding the safety and efficacy of observation as compared to tube thoracostomy (TT) for management of OPTX in emergency department trauma patients. ⋯ The existing evidence leads to the conclusion that observation is at least as safe and effective as tube thoracostomy for management of occult pneumothorax.

Mid-arm circumference can be used to estimate children's weights.
Accurate measurement of children's weight is rarely possible in paediatric resuscitation, and rapid estimates are made to ensure appropriate drug and fluid doses and equipment selection. Weight is commonly estimated from formulae based on children's age, or from their height using the Broselow tape. Foot-length and mid-arm circumference have also been suggested as the basis of weight-estimation formulae. ⋯ This weight-estimation formula based on mid-arm circumference is reliable for use in school-age children, and an arm-tape could be considered as an alternative to the Broselow tape in this population.

Interpretation and intent: a study of the (mis)understanding of DNAR orders in a teaching hospital.
Do not attempt resuscitation (DNAR) orders have been shown to be subject to misinterpretation in the 1980s and 1990s. We investigated whether this was still the case, and examined what perceptions doctors and nurses had of what care patients with DNAR orders receive. ⋯ Despite widespread use of DNAR orders, they are still misunderstood. This article highlights the frequency with which DNAR orders are interpreted to mean that other care should be withheld. In addition, it shows that although some doctors know that this should not be the case, they believe that DNAR orders affect the care that their patients receive. We propose that options for more detailed care plans should be embedded within the resuscitation decision and documentation to improve communication and understanding.
