Pneumothorax is present in about 20% of blunt major trauma cases. Insertion of an intercostal tube drainage is one effective treatment, however it is unclear whether the thoracostomy has more advantages if placed in the ventral (2.-3. intercostal space) or lateral (4.-6. intercostal space) approach. The aim of this study was to determine, whether there are any differences between the two approaches in respect of malposition and complications. ⋯ In our setting physicians preferred the lateral approach on-scene as well as in-hospital. In every fifth patient malpositioning of the tube was observed, mostly interlobal after lateral chest tube, however only few were associated with relevant clinical malfunctions. The probability of interlobal malpositioning is significantly higher when using the lateral approach as opposed to the ventral approach. Correction of malpositioned and ineffective chest tubes was necessary in every 17th case. No statistically significant difference between the two approaches for functional malposition was observed. Hence both approaches for emergency chest tube insertion seem to be equally justified.

The response to exchange transfusion with red blood cells (RBCs) saturated with carbon monoxide (CO) in amelioration of microvascular function and providing tissue protection in hemorrhagic shock resuscitation was investigated in the hamster chamber window model. Shock was induced by the withdrawal of 50% of blood volume (BV). Blood volume was restored 1 h after hemorrhage with a single volume infusion (resuscitation) of 25% BV with fresh RBCs (saturated or unsaturated with CO) suspended in human serum albumin (HSA). ⋯ CO saturated blood partially mitigated cell injury at 8 h after resuscitation. The precise cellular mechanisms involved require further elucidation. CO is a novel experimental strategy to improve tissue viability and requires the appropriated preclinical studies to confirm its efficacy.

Terlipressin as an adjunct vasopressor in refractory hypotension after tricyclic antidepressant intoxication.
To report the management of cardiovascular failure refractory to standard catecholamine therapy with terlipressin in a patient with tricyclic antidepressant (TCA) intoxication. ⋯ Successful management of cardiovascular failure with terlipressin after TCA intoxication refractory to catecholamines suggests a potential role for terlipressin as an adjunct vasopressor in severely hypotensive patients.

As part of a health system improvement project, the Republic of Croatia has been conducting a pilot project aimed at rationalizing care delivery across the primary care, hospital and secondary care systems. One component was the development of an emergency department at Dr T Bardek Hospital in Koprivnica and training of its staff. This paper describes how a training programme was conducted, using an established emergency department in Australia as the training host, and the outcome of the project. This type of training programme could form a model for specialist Emergency Medicine training in the future.

Case Reports
Amniotic fluid embolism after surgical trauma: two case reports and review of the literature.
Amniotic fluid embolism (AFE) is a relatively rare condition usually occurring during or shortly after pregnancy and is catastrophic in most cases. The classical description is a sudden onset of dyspnoea, cyanosis and hypotension out of proportion to the blood loss, followed quickly by cardiorespiratory arrest. ⋯ We report on two cases of severe and near fatal amniotic fluid embolism during pregnancy. Surgical trauma, caused by a blow in the stomach and a surgical intervention, was considered to be the aetiology.
