Increasing numbers of severely injured patients have been presenting to Emergency Rooms worldwide due to advances in pre-hospital trauma care. Some of these patients may be candidates for Emergency Department Thoracotomy (EDT). Large advisory bodies have identified selection criteria for EDT in Developed Countries, but there are no regional statistics to guide the selection process in Developing Caribbean Nations. ⋯ Several health care limitations have been uncovered in this setting that must be improved if we are to expect improved outcomes. Focused preparation of the Emergency Room is an initial step that can be easily achieved. We also need to define strict management protocols using selection criteria that are tailored to our local environment in order to exclude futile procedures in unsalvageable patients.

Retaining an appropriate level of moisture at the interface between a healing wound and an applied dressing is considered to be critical for effective wound healing. Failure to control exudate at this interface can result in maceration or drying out of the wound surface. The ability to control moisture balance at the wound interface is therefore a key aspect of wound dressing performance. ⋯ The composite hydrofibre dressing retained moisture at the wound interface throughout the experiments while areas of the foam dressing quickly became dry, even during constant injection of fluid. The abundance of sensors allowed a moisture map of the surface of the wound dressing to be constructed, illustrating that the moisture profile was not uniform across several of the dressings tested during absorption and evaporation of liquid. These results raise questions as to how the dressings behave on a wound in vivo and indicate the need for a similar clinical monitoring system for tracking wound moisture levels.
