The World Health Organization reports that trauma will be the major contributor to the 49.7 million annual deaths globally from non–communicable disease in 2020. Trauma and sepsis are the two leading causes of death worldwide. This project aims to examine the effects of trauma and severe infection on oxygen supply to various tissues and organs.
We will study what infection does to metabolism and the degree of inflammation in these tissues. The effects of resuscitation on these tissue parameters while using stored and fresh blood will also be studied.
This project had initially aimed to investigate changes associated with the development of shock and inflammation associated with trauma and haemorrhage. However, due to difficulties with developing a working animal model, this was changed to looking at shock and inflammation associated with sepsis.
The team was successful in developing a ‘two-hit’ ovine model of inflammation (endotoxaemia) and shock, followed by packed red blood cell transfusion, with monitoring at systemic and organ levels. Using this model, the team produced new knowledge on the effects of severe infection on oxygen supply to various tissues and organs; what infection does to metabolism and inflammation in these tissues; as well as the effects of resuscitation using stored and fresh blood on these tissue parameters. Further research papers outlining these results are pending.
