[Influence of the mode of collection on the result of blood cultures].
In a prospective study of 133 patients with suspicion of a septic process the influence of the withdrawal modus on the bacteriologic result was examined using an open blood culture system. For patients without pretreatment with antibiotics or without high temperature the "one time" withdrawal of the blood culture should be preferred to the "multi-time" method. A multi-time withdrawal showed similar and better evidence quotas with patients without fever and under influence of antibiotics. The result depends on the number of blood cultures for each patient. If there is presupposed a minimum of 2 positive blood cultures for each patient as indication of a septic process, a 83 per cent indication quota is attained with 12 one-time blood cultures, a 70 per cent indication quota with 8 blood cultures, and a 53 per cent indication quota with 4 blood cultures. In multi-time withdrawal the comparable indication quotas are 55, 45 resp. 32 per cent.
