Review[Strategy for peroperative fluid therapy--balancing the central blood volume].
The strategy for preoperative volume treatment is not clear, partly because of the difficulty in monitoring the central blood volume (CBV). The cardiovascular responses to hypovolaemic shock are reviewed with emphasis on the often very low heart rate, which develops when the CBV is reduced by about 30%. ⋯ It is concluded that the deviations reflect the CBV accurately in both experimental and clinical studies. A strategy that maintains the CBV ensures cerebral oxygenation even during extensive haemorrhage.

[Ambulance transportation and prehospital treatment in connection with admission for suspected acute myocardial infarction].
The aim was to describe ambulance transportation and pre-hospital treatment in connection with admission for suspected acute myocardial infarction. ⋯ The study showed that there were quality problems, as every third ambulance took more than 40 minutes to reach the hospital. It also showed that acetylsalicylic acid and morphine were used only to a limited extent in a pre-hospital situation.

[Advanced prehospital treatment of heart arrest by the mobile emergency unit in Aarhus. 1-year survival after out-of-hospital heart arrest--with focus on response time, survival, the given treatment and admission].
The Mobile Emergency Care Unit (MECU) in Arhus includes an experienced anaesthesiologist and a specially trained rescuer. It covers a radius of 25 km from the centre of Arhus with 330,000 inhabitants. Rescue workers in Denmark are permitted to give basic life support and defibrillation. The MECU carriers out advanced cardiac life support in accordance with "The 1998 Guidelines of the European Resuscitation Council". ⋯ These results illustrate that for patients with out-of-hospital cardiac arrest early treatment with advanced cardiac life support performed by experienced doctors probably had a positive impact on survival, as compared to basic cardiac life support.

Review[Ingestion of button batteries. Epidemiology, clinical signs and therapeutic recommendations].
The frequency of ingested button batteries is about 10 per million population per year, and one in every 1,000 battery ingestions causes serious injuries. Most of the patients are children. Seven to 20% develop transient symptoms, owing to irritation or superficial corrosion of the gastrointestinal tract. ⋯ Batteries lodged in the oesophagus may not cause initial symptoms, and it is recommended that when ingestion is suspected patients should be examined by fluoroscopy. Batteries in the oesophagus should be removed promptly by endoscopy, those distal to the oesophagus can be left to pass spontaneously. Passage can be ensured by examination of the stools.
