Comparative Study
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.

An evaluation of bag-valve-mask ventilation using an ergonomically designed facemask among novice users: a simulation-based pilot study.
We sought to compare the ability of novice operators to provide artificial ventilation using a standard facemask and a new ergonomically designed facemask. Whether or not proper technique was used was also assessed. ⋯ Novice airway operators were better able to provide facemask ventilation using an ergonomically designed mask than with a traditional facemask. We conclude that better hand position facilitating improved mask seal and less operator fatigue account for our findings.

Following a CBRN incident attending medical personnel will be required to instigate life saving airway interventions whilst wearing CBRN-PPE. CBRN-PPE is known to adversely affect fine motor skill but little is known about whether the position of the patient compounds this problem. ⋯ the position of the patient is likely to be an independent factor when choosing to either intubate or insert a LMA whilst wearing the current NHS CBRN-PPE.

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.
