Summary
Head injury is common in patients with major trauma, many of whom are young adults. The extent of head injury has a major influence on patient outcome. Low blood pressure after trauma worsens the extent of brain injury by decreasing its blood supply at a critical stage. Much of this secondary brain injury occurs before the patient reaches hospital.

The extent of head injury has a major influence on patient outcome. Low blood pressure after trauma worsens the extent of brain injury by decreasing its blood supply at a critical stage. Much of this secondary brain injury occurs before the patient reaches hospital. Hypertonic saline (HTS) is an intravenous salt solution which has been used in intensive care patients for many years to decrease brain swelling in head injured patients. We know that HTS can be given to patients before they reach hospital, is safe, and acts by rapidly increasing blood pressure and decreasing brain swelling. Accordingly HTS may minimise secondary brain injury and lead to increased survival. Importantly, HTS is likely to dramatically improve neurological function of survivors without any significant risk of side effects. This study is designed to determine the effectiveness of prehospital HTS in head injured trauma patients with traumatic coma and low blood pressure.Read moreRead less

A Randomised Controlled Trial Of Prophylactic Hypothermia In Severe Traumatic Brain Injury.

Summary
Patients who suffer from a severe head injury (traumatic brain injury) have a 50% chance of having severe long term neurological disability or death. Some of this damage occurs after the initial injury and may be reduced by artificially lowering the body termperature for up to 7 days to protect the brain from further damage. This project will determine if early, sustained cooling is safe and if it can improve the long term neurological outcomes of patients with traumatic brain injury.
Multi-centre Randomised Trial Of Early Decompressive Craniectomy In Patients With Severe Traumatic Brain Injury

Summary
Despite optimal neurosurgical and intensive care therapy, many trauma patients with severe brain injury (typically young males) have very poor long term neurological outcomes. Current knowledge suggests that a key contributor to secondary brain damage which occurs after injury and to poor neurological outcomes is brain swelling and subsequent increase in brain pressure. Present intensive care therapies to control brain pressure are often not effective, and favourable neurological outcomes occur ....Despite optimal neurosurgical and intensive care therapy, many trauma patients with severe brain injury (typically young males) have very poor long term neurological outcomes. Current knowledge suggests that a key contributor to secondary brain damage which occurs after injury and to poor neurological outcomes is brain swelling and subsequent increase in brain pressure. Present intensive care therapies to control brain pressure are often not effective, and favourable neurological outcomes occur in only 20-30% of these patients. Small studies suggest that a surgical operation called decompressive craniectomy (DC) may decrease brain pressure and improve neurological outcomes in these patients. DC involves temporarily surgically removing a piece of skull bone (during the swelling period) and replacing it when the swelling has subsided. DC is done under general anaesthetic in unconscious patients and is used occasionally at present, although due to insufficient research the benefits are controversial. The proposed study is a multi-centre randomised controlled study of best current therapies plus early decompressive craniectomy vs best current therapies alone in selected unconscious patients with severe head injury. The study outcome is patient neurological function measured 6 months after the injury. A study of this type is required before early DC could become a routine therapy in Australia. Next of kin will sign informed consent for the study and then also for the surgery if patients are randomised to surgery. The study will be managed at the Alfred Hospital-Monash University in Melbourne and includes fifteen collaborating ANZ neurotrauma centres over 3.0 years. There are >200 patients in Australia annually in this category with potential for DC to increase favourable outcomes in >40 patients annually. Lifetime costs for these patients with severe disability are > $2.4 million, so there may be substantial economic and social impact.Read moreRead less
A Randomised, Placebo-controlled Trial Of Erythropoietin In ICU Patients With Traumatic Brain Injury

Summary
Patients who suffer a moderate or severe head injury (traumatic brain injury) have a 50% chance of having a long term neurological disability or death. Erythropoietin is a medication which encourages red blood cell formation but its other beneficial effects are likely to improve outcomes after traumatic brain injury. This study will examine the safety and effects of erythropoietin on long term neurological function in patients who have suffered a traumatic brain injury.
How Does Activated Protein C Create Intact, Non-leaky, Stable Blood Vessels?

Summary
Vascular dysfunction is a common feature of many diseases, including sepsis, diabetes, atherosclerosis, tumours and asthma. These vessels have compromised structural and functional integrity, leading to leakage of blood components and causing inflammation in tissues. Based on our recent findings, this project aims to discover how activated protein C creates normal, healthy non-leaky blood vessels and prevents vascular dysfunction in disease.
Functional Electrical Stimulation Assisted Cycling (eStimCycle):A Novel Intervention To Improve Outcomes In The Critically Ill

Summary
The legacy of critical illness leaves millions of survivors worldwide with long lasting deficits in physical and brain function as well as anxiety, depression and post-traumatic stress disorder. Early rehabilitation may prevent or minimise these effects. This study evaluates the effectiveness of functional electrical stimulation of muscles with assisted in-bed cycling (eStimCycle) on muscle bulk, strength, physical and brain function at hospital discharge, 6 and 12 months.
Therapeutic Thermal Regulation In Critical Illness

Summary
Patients who are admitted to intensive care units often develop abnormalities of their body temperature as part of their illness. Common illnesses include infections and injuries to the brain from trauma or strokes. Clinicians are unsure of how to react to these changes in temperature. My research is designed to provide high quality evidence on body temperature and the use of treatments, so that clinicians can improve patient outcomes.
