Hypoxia Clinical Trial - Conservative Versus Liberal Oxygenation Targets

Status Completed

Clinical Trial Summary

A feasibility study to determine if it is possible to perform a safe, adequately powered, and affordable multi-centre study in critically ill children comparing current practice of liberal targets for systemic oxygen levels with more conservative targets.

Clinical Trial Description

Around 19,000 critically ill children are admitted to paediatric intensive care units (PICU) each year in the UK. A large number of these children need breathing support, and this is usually provided through an invasive machine called a 'ventilator'. Clinicians make decisions for treatment based on how much oxygen their patient has in their blood (this is called oxygen saturation or oxygenation) and currently the amount of oxygen critically ill children need is not fully understood. This means that some clinicians use a lower oxygen saturation target, and others, a higher target. This may be problematic as research in neonates (babies) and adults has shown that oxygen saturation levels can influence a patient's chance of survival, how long they stay in hospital and healthcare costs.

Response to oxygen is different in babies, children and adults. This means that the results from the neonatal and adult research are unlikely to be valid or applicable in children due to age-related differences. Urgent high quality clinical evidence is therefore needed to inform on the best targets of oxygenation during critical illness in children.

As large clinical trials are expensive to conduct, it is important to demonstrate that a large-scale trial can be done and that the different components of a trial can all work together. Therefore, the Oxy-PICU study is a 'pilot randomised clinical trial' (a smaller version of the trial we would like to conduct) and will test the feasibility and safety of conducting a large scale trial comparing a restrictive oxygen saturation target (88-92%) with a more liberal oxygen saturation target (>94%). Oxy-PICU will also collect blood and urine samples to allow for in depth study of the biology of the different oxygenation targets.

The pilot trial will take place at three PICUs (two in London and one in Southampton) and aims to include between 115-125 eligible children over six months. Given the emergency nature of these children and the need to provide immediate care, informed consent will be sought after the children are entered into the study (this is known as deferred consent). ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
