Sodium Awareness in Lactation Trial
(SALT)
What this study is about
SALT is a multi-centre, non-blinded, non-randomly assigned forward-looking interventional pilot study teaching lactating parents of hospitalized preterm infants how to test their breastmilk sodium (Na) using point-of-care (POC) meters. A drop in Na is a sign of secretory activation in the breast that is associated with adequate short and long-term breast milk volumes in this vulnerable population.

SALT is a multi-centre, non-blinded, non-randomized prospective interventional pilot study teaching lactating parents of hospitalized preterm infants how to test their breastmilk sodium (Na) using point-of-care (POC) meters. A drop in Na is a sign of secretory activation in the breast that is associated with adequate short and long-term breast milk volumes in this vulnerable population.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Consent provided
- Have delivered a preterm singleton or twin infant at \<35 weeks gestation admitted to a study NICU at birth or transferred into a study NICU from another NICU within the first 72 hours postpartum
- Day 5 or less postpartum (Day 1 = day of delivery) upon enrollment (ideally day 3 or less)
- Plans to lactate at least 2 weeks and initiate lactation with a breast pump
- Expected infant NICU stay of 7+ (ideally 14+) days in enrollment NICU(s)
Exclusion criteria
- Potential study participant's infant is critically ill and not expected to survive or has lethal diagnosis with plans by medical team/family to redirect care
- Has delivered triplets or higher order multiples (potential confounder for lactation challenges; of note, triplets or higher are rare, on the order of a few parents annually)
- Lactation contraindication(s) (i.e., active chemotherapy) or declines lactation initiation
- History of breast surgery that may affect ability to lactate (i.e., breast reduction; breast augmentation that utilized nipple incisions)
- Using or planning to use hormonal birth control in the first 14 days post-partum as may affect secretory activation/lactation
- Unable/unwilling to be present in study NICU during any of first 5 days postpartum
- Presumption by the medical team that infant will be in study NICU for \<5 days
Where
- Seattle, Washington
Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
