About this study
The purpose of this study is to look at whether the use of a simple technique before surgery, which involves inflating a blood pressure cuff on the infant's leg, can improve development of language, motor and thinking skills at 12 months of age. Some research has found that a brief shortage of blood supply to an organ (such as a leg) at level that does not cause harm may help the body to tolerate a longer and more severe shortage of blood (for example, during surgery).

Neurodevelopmental Assessment:
The Bayley Scales of Infant and Toddler Development, Third Edition (Bayley-III)9 assesses the developmental functioning of infants and young children between the ages of 1 month and 42 months. Cognitive, language, and motor development are assessed through structured play activities. Social-emotional and adaptive functioning are assessed through parent questionnaires. Administration time is 45 - 60 minutes, depending on the child's performance and behavior. Psychometric properties are well defined and acceptable. Composite scores for cognitive, language, motor, social-emotional, and adaptive behavior are standardized with a mean of 100 and a standard deviation of 15.
The Infant Development Inventory (IDI)10 will also be used to assess neurodevelopmental functioning, based on parent report. Parents are asked to rate their child's developmental skills in five domains: social, self help, gross motor, fine motor and language. Administration time is approximately 10 minutes. Infants are categorized as delayed or not delayed for each of the five domains.

The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 16 Mar 2020. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Neurodevelopment (time frame: 12 months of age). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 Mar 2020; AzTrials last refreshed its copy on 7 Nov 2026.
