Emergency patients receiving anaesthesiologist-based pre-hospital treatment and subsequently released at the scene.
The Mobile Emergency Care Unit in Odense, Denmark consists of a rapid response car, manned with an anaesthesiologist and an emergency medical technician. Eleven per cent of the patients are released at the scene following treatment. The aim of the study was to investigate which diagnoses were assigned to patients released at the scene following treatment, to investigate the need for secondary contact with the hospital and to assess mortality in patients released at the scene. ⋯ Patients treated and released at the scene presented poorly defined conditions. Ninety-three per cent of all cases required no secondary contacts with the health care system. However, caution should be exercised when releasing patients at the scene following traffic accidents.

Early intensive care unit-acquired hypernatremia in severe sepsis patients receiving 0.9% saline fluid resuscitation.
Intensive care unit (ICU)-acquired hypernatremia is associated with increased mortality and ascribed to excessive sodium/insufficient free water intakes. We aimed to determine whether the volume of intravenous 0.9% saline fluid resuscitation was associated with hypernatremia in severe sepsis. ⋯ Early acquired hypernatremia is a frequent complication in severe sepsis patients and is associated with the volume of 0.9% saline received during the first 48 h of admission.

Pulmonary function after hemorrhagic shock and resuscitation in a porcine model.
Hemorrhagic shock may trigger an inflammatory response and acute lung injury. The combination adenosine, lidocaine (AL) plus Mg(2+) (ALM) has organ-protective and anti-inflammatory properties with potential benefits in resuscitation.The aims of this study were to investigate: (1) pulmonary function and inflammation after hemorrhagic shock; (2) the effects of ALM/AL on pulmonary function and inflammation. ⋯ Hemorrhagic shock and resuscitation did not cause acute lung injury or pulmonary inflammation. The question whether ALM/AL has the potential to attenuate acute lung injury is unanswered.

Calculation of volatile anaesthetics consumption from agent concentration and fresh gas flow.
The assessment of volatile agents' consumption can be performed by weighing vapourisers before and after use. This method is technically demanding and unavailable for retrospective analysis of anaesthesia records. Therefore, a method based on calculations from fresh gas flow and agent concentration is presented here. ⋯ By application of the presented specific volatile agent constants and equations, it becomes easy to calculate volatile agent consumption if the fresh gas flows and the resulting inhaled concentration of the volatile agent are known. By this method, it is possible to extract data about volatile agent consumption both ways: (1) retrospectively from sufficiently detailed and accurate anaesthesia recordings, as well as (2) by application of this method in a prospective setting. Therefore, this method is a valuable contribution to perform pharmacoeconomical surveys.
