Trial of a laminar air-flow enclosure for the control of infection in a burns operating theatre.
A series of 22 patients with full-skin thickness burns had skin grafting operations in a Piekenrood-Vinitex BV open-topped laminar air-flow enclosure, and a parallel control series of 18 patients were grafted in the same operating room without the use of the laminar flow unit; the operating room in which both series of operations were performed had standard plenum ventilation with 20 air changes per hour. None of the patients acquired on their burns Staph. aureus of phage types and antibiotic sensitivity patterns corresponding with those isolated from carriers who were in the theatre at the time of the operation; 16 patients acquired on their burns strains of types corresponding with those of strains isolated from burns of other patients in the ward. Settle plates exposed during operations showed a relatively small reduction in bacterial counts associated with the use of the laminar flow enclosure.
