The ambulance helicopter is a prerequisite for centralised emergency care.
During the summer seasons of 1978-1983 (56 weeks), trial activity with a physician-manned ambulance helicopter was carried out in the County of Stockholm (population 1.5 million). The area includes an extensive archipelago. Within the region there are 11 large general hospitals, three of which are supplied with a helicopter pad. ⋯ By special training of emergency call operators, the number of unnecessary helicopter missions could be minimised (9% of all missions). To continuing specialisation and centralisation of emergency care with extended catchment areas, demands an advanced transport system. This trial has shown that through the use of a physician-manned ambulance helicopter the emergency care within the region can be centralised with retention of adequate turn-out times.

Clinical TrialHigh doses of corticosteroids in the treatment of septic shock.
High doses of corticosteroids are reported to be beneficial in the treatment of septic shock in many animal species, e.g. dog, rat and rabbit. Recent findings in baboons subjected to E. coli shock indicate that early treatment with a combination of antibiotics and steroids strongly enhance survival rate. ⋯ In part this may be explained by variations in the amount of steroids used or by the fact that in some studies the steroid is administered late in shock. The dose recommended, 30 mg/kg bw of methylprednisolone or an equivalent amount of another glucocorticoid given once or twice, is based on animal as well as clinical documentation.

Renal oxygen and lactate metabolism in hemorrhagic shock. An experimental study.
Renal oxygen and lactate metabolism as well as central and renal hemodynamics were investigated in hemorrhagic shock in dogs. The animals were bled progressively until a 40-50% blood loss was achieved. Following a 20-, 40-, 60-, or 80-minute shock phase the shed blood was gradually returned. ⋯ After reinfusion of shed blood renal lactate uptake failed to return to the prehemorrhage level. The renal lactate uptake was inversely related to the arterial pH under baseline conditions whereas after blood return the correlation between these parameters was less significant. The present findings suggest that in hemorrhagic shock renal metabolism may become limited by hypoxia and the susceptibility to the development of hypoxia is greater in the cortex than in the medulla.(ABSTRACT TRUNCATED AT 400 WORDS)
