Appropriate fluid replacement is an essential component of trauma patient resuscitation. Once haemorrhage is controlled, the restoration of normovolaemia is a priority. In the presence of uncontrolled haemorrhage, aggressive fluid resuscitation may be harmful. ⋯ A number of haemoglobin solutions are under development but one of the most promising of these has been withdrawn recently. It is highly likely that at least one of these solutions will eventually become routine therapy for trauma patient resuscitation. In the mean time, contrary to traditional teaching, recent data suggest that a restrictive strategy of red cell transfusion may improve outcome in some critically ill patients.

Inter-individual variability in drug response is a major clinical problem. Adverse drug reactions (ADRs) are common, are responsible for a number of debilitating side effects following drug therapy and are a significant cause of death. It is now clear that much of the observed variability in drug response has a genetic basis, arising as a result of genetically-determined differences in drug absorption, disposition, metabolism or excretion. ⋯ Individuals at risk of developing ADRs as a result of genetically-determined variation in genes such as CYP2D6 can now be identified using DNA-based tests. A detailed knowledge of the genetic basis of individual drug response is potentially of major clinical and economic importance and could provide the basis for a rational approach to drug prescription. This would have significant benefits for human health.

In the UK, emergency ambulances are responding to astonishing increases in levels of emergency calls, in the order of a 40% increase nationally in the last 5 years. Pressures in primary care service out-of-hours provision, and increasing community-based care of elderly patients, as well as increased expectation by the public are contributory causes. Services are also being pressed to improve response times, particularly to life-threatening cases. These various aspects are discussed below.

ReviewOptimal use of resources for the treatment and prevention of injuries.
Injuries are an important cause of mortality and morbidity. Although accidental injury rates have been declining throughout the twentieth century in the UK, this pattern has been variable. ⋯ Although there is little evidence that road traffic accident case fatality rates have been improving, there is some evidence that improvements in trauma care have been responsible for reducing injury death rates in children. Thus, although there have been considerable successes in the primary prevention of accidents, and the secondary prevention of injuries in accidents, there is an important role for tertiary prevention, that is in the prevention of avoidable outcomes through good trauma care.

Since the introduction of manual positive pressure ventilation during the Copenhagen polio epidemic of 1952, a range of mechanical devices and methods of ventilatory support have been developed to provide life-saving respiratory therapy to critically ill patients. In addition to the development of the equipment hardware to enable effective mechanical ventilation, there has been a gradual realisation that a single mode of ventilation is not universally applicable to all patients, individual pathologies, or to individual patients at various stages in the evolution of their pulmonary pathology. ⋯ This iatrogenic problem is known as ventilator induced lung injury and, although it may be a problem in any patient requiring mechanical ventilation for any reason, is of particular importance to those patients requiring mechanical ventilation as a consequence of trauma. This chapter describes the range of ventilatory support techniques available, the problem of ventilator induced lung injury with specific reference to trauma patients and offers a strategy for ventilatory support in the trauma patient.
