Summary
In this study, we will assess neurocognitive function in patients with obesity hypoventilation syndrome (OHS – too slow or too shallow breathing) using a battery of tests including driving simulation, before and after 3 months of positive airway pressure therapy (CPAP). This will assess if chronically raised carbon dioxide levels contribute to impaired thinking capacity in addition to low oxygen levels.
Targeted Therapeutic Mild Hypercapnia After Resuscitated Cardiac Arrest: A Phase III Multi-Centre Randomised Controlled Trial (The TAME Cardiac Arrest Trial)

Summary
The TAME Cardiac Arrest trial will study the ability of higher carbon dioxide (CO2) levels to reduce brain damage, comparing giving patients ‘normal’ to ‘slightly higher than normal’ blood CO2 levels and assessing their ability to return to normal life-tasks. It will be the largest trial ever conducted in heart attack patients in the ICU. This therapy is cost free and, if shown to be effective, will improve thousands of Australian lives, transform clinical practice, and yield major savings.

Summary
In the first few days after birth, some premature babies develop low blood pressure. It is thought that this meant that the amount of blood and oxygen going to the brain would also fall. If blood pressure became very low, this could injure the brain. Drugs are used to prevent low blood pressure, but their effect on blood flow and oxygen in the brain is uncertain. This study aims to develop simple cotside monitoring procedures that allow neonatologists to monitor oxygen supply and blood flow in t ....In the first few days after birth, some premature babies develop low blood pressure. It is thought that this meant that the amount of blood and oxygen going to the brain would also fall. If blood pressure became very low, this could injure the brain. Drugs are used to prevent low blood pressure, but their effect on blood flow and oxygen in the brain is uncertain. This study aims to develop simple cotside monitoring procedures that allow neonatologists to monitor oxygen supply and blood flow in the brain in tiny babies who weigh less than 1000gm, and what happens within the brain when drugs are given to raise blood pressure. We will employ a new instrument that generates low intensity near infrared light which passes safely into the brain and is absorbed according to the amount of oxygen present in very small blood vessels. As the methodology is new, we intend to first validate the measurement in immature lambs. The instrument will then be applied in studies of babies undergoing intensive care and at risk for low pressure and brain injury, as many as 5000 babies each year in Australia.Read moreRead less
