As a part of the chain of survival, the emergency medical communication centre (EMCC) and the emergency medical dispatcher (EMD) has an important role in early identification of out-of-hospital cardiac arrests (OHCA). The EMD may provide instructions to the caller and thereby initiate cardiopulmonary resuscitation in a substantial number of subjects and thus contribute to increased survival. The EMCC provides a response with first responders, ambulances, physician manned units and potentially other health care providers. ⋯ In research there is a growing focus on the EMCC/EMDs impact on survival in OHCA. The lack of standards in reporting results from medical dispatching is an obstacle for thorough evaluation of results in this area and comparison of data. The objective for this paper is to introduce a framework for uniform reporting of the dispatching process for quality improvement, collecting and reporting data and exchanging information regarding OHCA.

Randomized Controlled Trial Comparative Study
Comparison of six different intubation aids for use while wearing CBRN-PPE: a manikin study.
Respiratory failure following chemical exposure can be fatal and although supraglottic airway devices have been evaluated for use in the management of CBRN casualties' intubation remains the gold standard airway. ⋯ In this manikin-based study all intubation aids evaluated while wearing CBRN-PPE were adversely affected by the loss of dexterity associated with wearing Butyl gloves. Standard intubation and intubation utilising a stylet resulted in the fastest intubation times; whereas the ILMA offers the highest intubation success rate and was deemed to be the easiest intubating aid to use. An important consideration with regards future research is the impact of a learning curve with regards to different intubation aids and whether preassembling all the intubation aids prior to the intubation attempt may improve intubation speed. The impact of intubator familiarity with regards to individual intubation aids is also an important consideration but established intubation aids like the Bougie are more difficult to use when dexterity is reduced due to CBRN-PPE.

Comparative Study
Difficult prehospital endotracheal intubation - predisposing factors in a physician based EMS.
For experienced personnel endotracheal intubation (ETI) is the gold standard to secure the airway in prehospital emergency medicine. Nevertheless, substantial procedural difficulties have been reported with a significant potential to compromise patients' outcomes. Systematic evaluation of ETI in paramedic operated emergency medical systems (EMS) and in a mixed physician/anaesthetic nurse EMS showed divergent results. In our study we systematically assessed factors associated with difficult ETI in an EMS exclusively operating with physicians. ⋯ In a physician staffed EMS difficult prehospital ETI occurred in 13% of cases. Predisposing factors were limited surrounding space on scene and certain biophysical conditions of the patient (short neck, obesity, face and neck injuries, and anatomical restrictions). Unexpected difficult ETI occurred in 5% of the cases.

Comparative Study
Visual evaluation of left ventricular performance predicts volume responsiveness early after resuscitation from cardiac arrest.
Haemodynamic optimisation is a fundamental goal of post-cardiac arrest therapy. Therefore, predicting volume responsiveness is a key issue in therapy of these high-risk patients and transoesophageal echocardiography (TEE) may provide helpful information. The aim of the present study was to evaluate the performance of visual evaluation (eyeballing) of standardised TEE-loops to predict volume responsiveness during post-cardiac arrest period. ⋯ In post-cardiac arrest period, visual evaluation of long-axis TEE loops allows prediction of volume responsiveness with good sensitivity and reasonable specificity even by novice users, and may therefore be suitable for implementation into treatment protocols.

Comparative Study
Good outcome in every fourth resuscitation attempt is achievable--an Utstein template report from the Stavanger region.
Out-of-hospital cardiac arrest (OHCA) is a major cause of death in the western world. We wanted to study changes in survival over time and factors linked to this in a region which have already reported high survival rates. ⋯ Overall, good outcome is now achievable in every fourth resuscitation attempt and in every second resuscitation attempt when patients have a shockable rhythm. The reason for the better outcomes is most likely multi-factorial and linked to improvements in the local chain of survival.
