Mannion and Chaloner have emphasised the importance of packing open a
potentially contaminated wound. They have not added the important step of
immobilising the soft tissues and, where possible, the joint above and
below the wound, with a plaster-of Paris cylinder to prevent bacterial
spread by movement in the tissue planes.
This is useful, too, in multiple small superficial soft tissue
puncture wounds. These may form localised small abscesses which can be
drained easily at a later date.
Most bacteria are sessile. When the tissues are immobilised in this
way, systemic infection is avoided and local collections of pus can be
drained when the dressing is changed first after 48 hours. The cast is
retained until clean granulation tissue covers the entire exposed wound
surface.
The occlusive plaster technique was brought to this country by
Professor Josep Trueta after the Spanish Civil War.
