Fluids as oxygen carriers and the potential role in trauma resuscitation

Shirley, P. J — 2008-08-29

Patients with major trauma present a challenge, often using large quantities of banked blood both at the time of injury and during their hospital stay. Blood transfusion is not without risk and is associated with high costs; it is immunosuppressive, rendering patients more susceptible to infection. In the western world, banked blood is fully screened and relatively safe; the same is not true in parts of the developing world, where high rates of HIV carriage make blood transfusion a risky undertaking. Additionally, blood transfusion as a vector for transmission of illnesses such as prion disease is a distinct possibility, for both the developed and developing world alike. The introduction of artificial blood substitutes would ameliorate some risk and also remove the cost of extensive blood testing. For trauma outside hospital, blood substitutes could compete directly with fluid resuscitation as donated blood is not usually available. Patients with prolonged transport times would appear to be the most obvious beneficiaries and volume expansion, along with improvement in oxygen-carrying capacity would be the ultimate goal. All clinicians confronted with the need for transfusion of homologous blood would welcome the development of a safe and reliable alternative to red blood cells in order to ensure oxygen transport to the tissues. However, even though research on red cell substitutes started more than 100 years ago, even now none of the heavily investigated compounds based on haemoglobin or perfluorocarbons has been released in Europe or the USA for routine clinical use.

Acetabular fractures in the 21st century

Rickman, M., Bircher, M. — 2008-08-29

Acetabular fractures are uncommon other than in the polytrauma setting, and most orthopaedic surgeons will never develop a wide exposure to them. The early management of these injuries can have profound effects on the long term outcomes from what is often a significant injury in a young patient. We present a current review of the anatomy, classification and management guidelines for acetabular fractures, including a comprehensive review of the major decision making processes, as well as describing the most common complications and the expected outcomes.

Injuries to the proximal humerus

Costan, L., Ashwood, N. — 2008-08-29

Five to seven percent of all fractures involve the humerus, with most occurring in ladies over the age of 60 who have osteoporosis. and suffer fractures after a simple fall. In younger individuals such fractures result from high energy injuries (road traffic accidents). Around 75% are non-displaced fractures according to Neer's classification and can be treated non-operatively. The remaining 25% require surgical intervention based on the understanding of the anatomy of the proximal, the mechanism of the injury and the quality of the patient's bone. The displaced fractures may lead to avascular necrosis, osteoarthritis, pseudoarthrosis, and reduced motion and function. Involvement of the specialist is needed at an early stage in order to restore the limb functionality and the quality of life.

Paediatric chest trauma (part 1) -- Initial Lethal Injuries

Kerr, M., Maconochie, I. — 2008-08-29

Chest trauma is the second greatest cause of mortality from trauma, a leading cause of death in children over the age of one. Prompt diagnosis can be difficult as the underlying thoracic injuries are often disproportionately severe compared to the visible surface injury and symptoms may not appear for several hours. Diagnosis is easily underestimated, delayed or missed. This is a two part article reviewing paediatric chest trauma and its current management. The injuries are usefully classified into six lethal injuries that need excluding in the primary survey and six hidden injuries that must be considered in the secondary survey. The first article reviews paediatric anatomy and biomechanics, and mechanisms of injury with a view to improving the awareness and understanding of the unique response of children to thoracic trauma. This is followed by an in depth review of each of the six lethal injuries. The subsequent article reviews the six hidden injuries as well as the role of chest trauma in non-accidental injury.

Paediatric chest trauma (part 2) -- Hidden Injuries

Kerr, M., Maconochie, I. — 2008-08-29

Chest trauma is the second greatest cause of mortality from trauma, a leading cause of death in children over the age of one. Prompt diagnosis can be difficult as the underlying thoracic injuries are often disproportionately severe compared to the visible surface injury and symptoms may not appear for several hours. Diagnosis are easily underestimated, delayed or missed. This is the second of a 2 part article reviewing Paediatric chest trauma and its current management. The injuries are usefully classified into 6 lethal injuries that need excluding in the primary survey and 6 hidden injuries that must be considered in the secondary survey. The 6 lethal injuries are covered in the first part of this article along with biomechanics and mechanisms of injury. This article looks in depth at the 6 hidden injuries, along with a review of chest trauma in non-accidental injury.
