[Show abstract][Hide abstract] ABSTRACT: Over the last 5 years plastic isolators have been used for the prevention of infection in patients with severe neutropenia. Fifteen patients in differing stages of acute myeloid and chronic granulocytic leukaemia were managed in isolators for a total of 110 patient-weeks. The mean duration of isolation for each patient was 7·4 weeks with a range of 2-14 weeks. There was no evidence that any of the isolated patients acquired infection with any exogenous micro-organism. The psychological problems of isolation proved less onerous for the patients than had been anticipated by the medical and nursing staff and no patient had to be removed from isolation for psychiatric reasons. Unfortunately the reduced incidence of clinical infection in the isolated patients was not obviously associated with an increase in effectiveness of their anti-leukaemic treatment.

[Show abstract][Hide abstract] ABSTRACT: The therapeutic method of reverse isolation in patients using an aseptic environment in the Life Island or Laminar Air Flow Unit apparatus systems is described on the basis of data from the literature and the authors' experience. A historical summary of views on treatment in an aseptic environment is followed by a description of the method of work with the system of reverse isolation, including important technical, operational and other data. The main indications for treatment are given and the authors' experience with the reverse isolation of 36 patients suffering from blood diseases who were treated in this way over the past four years is evaluated. The experience gained confirms data from the literature that reverse isolation is unequivocally successful in reducing the number of infections in immunologically weakened persons. Other aspects have not yet been definitely assessed.
[Show abstract][Hide abstract] ABSTRACT: This article examines a specific technology, the germ-free "isolator," tracing its development across three sites: (1) the laboratory for the production of standard laboratory animals, (2) agriculture for the efficient production of farm animals, and (3) the hospital for the control and prevention of cross-infection and the protection of individuals from infection. Germ-free technology traveled across the laboratory sciences, clinical and veterinary medicine, and industry, yet failed to become institutionalized outside the laboratory. That germ-free technology worked was not at issue. Working, however, was not enough. Examining the history of a technology that failed to find widespread application reveals the labor involved in aligning cultural, societal, and material factors necessary for successful medical innovation.
