The Use of Computed Tomography (CT) to Measure Skeletal Muscle Quantity and Quality in Patients Receiving ECMO

February 14, 2019 updated by: Danielle Bear, Guy's and St Thomas' NHS Foundation Trust
This is a retrospective, observational study and will investigate the clinical predictive value of and change in muscle quantity and quality in critically ill patients with severe respiratory failure requiring veno-venous extracorporeal membrane oxygenation (VV-ECMO).

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Detailed Description

The use of veno-venous extra-corporeal membrane oxygenation (VV-ECMO) for severe respiratory failure - mainly hypoxaemia - has increased over recent years. Similar to the general population in the Intensive Care Unit (ICU), these patients become deconditioned, severely weak (ICU acquired weakness- ICUAW) and require prolonged rehabilitation after disconnection from VV-ECMO. However, data regarding the magnitude of muscle wasting and recovery in this specific group is lacking.

Both poor muscle quantity and quality have been found to be a predictor or poor outcome. As all patients receiving VV-ECMO at our hospital will get an initial CT scan of their chest, abdomen and pelvis, these CT scans will be used to measure muscle quantity and quality of different muscle groups of the abdomen at admission and then using any follow-up CT scan performed within 10 days. In addition, the relationship between the loss of muscle over the course of VV-ECMO and perceived recovery of renal function at ICU discharge will be investigated.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.

Measure Description
Time Frame
All cause mortality
Time Frame: On ECMO (expected to be about 10 days)
Using total muscle quantity and quality measured from CT slice of the third lumbar region.

Secondary Outcome Measures
