Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The most common reason for admitting babies and infants to an intensive care unit is due to respiratory distress (breathing difficulties). At present there are a number of different treatments for respiratory distress. These include drug treatments; non-invasive ventilation, where oxygen is given at high pressure to push it through the baby's lungs: ventilation where the baby is put on a breathing machine; or Extracorporeal Membrane Oxygenation (ECMO). This works by taking the blood from the body via a tube (usually) in the baby's neck, redirecting through a machine that oxygenates the blood, then returning it to the baby through another tube. Currently we know little about how different treatments have a different impact on brain perfusion (how much oxygen the brain gets). Using specialist, noninvasive ultrasound and doppler techniques, we are proposing to monitor the effect of these treatments on the brain.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Following admission to Paediatric Intensive Care Unit, the clinical team will approach the parents of patients admitted with respiratory failure and introduce the research project. It is unlikely that parents will be have the capacity to provide meaningful full consent at this stage, as admission will be as an emergency. Therefore a two staged approach is proposed. Clinicians will act as gatekeepers to the parents. Parents/ patients deemed suitable for recruitment by clinicians will be provided with a brief explanation of the scan, and introduced to the researcher. Parents/patients may be deemed unsuitable should there be communication issues, legal issues (such as children in care) or clinical issues (where clinicians feel the patient is unlikely to survive and the research would be intrusive). With the parent's permission (documented in the research paperwork), scan data will collected from the patient. However, this will not be analysed or downloaded until after the second stage of consent. At a time deemed appropriate by the clinicians (based on clinical experience, this is expected to be within 24 hours of arrival) the researcher will provide a full explanation of the research and formally record parental consent on an approved form. At this point data generated will be downloaded and analysed. Should the parents refuse no more data will be collected. The measurements of brain blood flow will be taken using small probes located either side of the head. These will be held in place by either tape or a tubular bandage. Using an ultrasound images of the blood vessels (and flow) in the brain will also be measured at the same time. These measurements will be taken for 5-10 minutes on each occasion. Depending on treatment pathway, the data will be collected as follows: Measurements will be taken before treatment starts (in ECMO only). When the child is going onto treatment (during cannulation (ECMO) or intubation conventional)).

One hour after treatment has begun (ECMO only) 24 hours after treatment has started and then on a daily basis for the duration of treatment. During the weaning period where the patient is being prepared to come off treatment.

When the patient is being took off treatment (de-cannulation/extubation). One hour after they have been took off treatment. 24 hours after treatment has stopped. Not all the time points at which data will be collected will be applicable in every case.

Parents can withdraw consent at any point until data is analysed. No identifiable data will be recorded, apart from the consent forms.
