Resuscitation

Haemorrhagic shock causes ischaemia and subsequent fluid resuscitation causes reperfusion injury, jointly resulting in high morbidity and mortality. We tested whether the anti-inflammatory fibrin-derived peptide, Bbeta(15-42), also called FX06, is tissue protective in a model of haemorrhagic shock. ⋯ FX06 - when administered as an adjunct to fluid resuscitation therapy - is organ protective in pigs. Further investigations are warranted to reveal the protective mechanism of FX06.

Comparative Study
Emergency cricothyrotomy-a comparative study of different techniques in human cadavers.
Emergency cricothyrotomy is the final lifesaving option in "cannot intubate-cannot ventilate" situations. Fast, efficient and safe management is indispensable to reestablish oxygenation, thus the quickest, most reliable and safest technique should be used. Several cricothyrotomy techniques exist, which can be grouped into two categories: anatomical-surgical and puncture. ⋯ In inexperienced health care personnel, anatomical-surgical techniques showed a higher success rate, a faster tracheal tube insertion time and a lower complication rate compared with puncture techniques, suggesting that they may be the techniques of choice in emergencies.

This study aimed to determine factors linked to hypothermia (<35 degrees C) in Queensland trauma patients. The relationship of hypothermia with mortality, admission to intensive care and hospital length of stay was also explored. ⋯ Trauma patients in a predominantly sub-tropical climate are at risk of accidental and endogenous hypothermia, with associated higher mortality and care requirements. Prevention of hypothermia is important for all severely injured patients.

Under current resuscitation guidelines symptomatic ventricular tachycardia (VT) with a palpable pulse is treated with synchronised cardioversion to avoid inducing ventricular fibrillation (VF), whilst pulseless VT is treated as VF with rapid administration of full defibrillation energy unsynchronised shocks. The additional delay in setting up the ECG to provide accurate synchronisation has been the main reason for advocating this approach, although many current defibrillators allow accurate synchronisation via just the adhesive defibrillator pads. The aim of this study was to investigate whether the timing of defibrillatory shocks in rapid VT-affected resuscitation outcome. ⋯ Defibrillator shocks within the QRS complex had a success rate of 93% compared to a success rate of 42% for outside the QRS complex (p=0.0016 two-tailed Fishers' exact test, odds ratio=19.6, 95% limits=3.1-123.1). There was no significant effect of age or sex of the patient, the underlying heart disease, rate of VT or anti-arrhythmic medication on the outcome, although the number of patients was too small to definitively exclude this. Therefore, defibrillation shocks delivered shortly after the peak of the QRS complex in rapid VT do appear to offer significant advantages over defibrillation shocks at other parts of the cardiac cycle for very rapid ventricular tachycardia.

Physicians are expected to manage their role as teamleader during resuscitation. During inter-hospital transfer the physician has the highest medical credentials on a small team. The aim of this study was to describe physician behaviour as teamleaders in a simulated cardiac arrest during inter-hospital transfer. Our goal was to pinpoint deficits in knowledge and skill integration and make recommendations for improvements in education. ⋯ Junior physicians performed well with respect to the treatment given and the delegation of tasks. However, variations in the time of initiation it took for each treatment indicated lack of leadership skills. It is imperative that the education of physicians includes training in leadership.
