taVNS-Paired Breastfeeding to Improve Breastfeeding at Discharge
What this study is about
Investigators aim to improve the skills of premature or sick term infants in breastfeeding by boosting motor learning with transcutaneous vagus nerve stimulation. Investigators will recruit 10 premature, ≥ 35 weeks gestational age, or convalescing sick term infants admitted to the NICU at MUSC to participate in this study.
View original scientific description
Investigators aim to improve the skills of premature or sick term infants in breastfeeding by boosting motor learning with transcutaneous vagus nerve stimulation. Investigators will recruit 10 premature, ≥ 35 weeks gestational age, or convalescing sick term infants admitted to the NICU at MUSC to participate in this study. Infants will receive taVNS treatments once a day with breastfeeding's for up to 14 days. Before each treatment, the researcher will determine how much electrical stimulation is needed for the infant to feel a slight tingle without discomfort, and during daily treatment paired with breastfeeding the infant will continue to receive this level of electrical stimulation, coinciding with latching and sucking, repeated over the duration of the feed. Investigators will collect information about the pre- and post-feed weights, the length of time for each feed, and observations of latch, suck, and swallow techniques by the infant from parents and the lactation consultant. Investigators will also evaluate parental satisfaction associated with their infant's ability to breastfeed after taVNS by providing parental satisfaction surveys at the beginning, after 1 and 2 weeks, and at 3 months after the end of the study to assess infants' progress in and maintenance of breastfeeding abilities. If the pairing of breastfeeding with taVNS is able to result in improved outcomes of effective breastfeeding in infants in the neonatal intensive care units, this intervention could be further utilized by NICUs to increase the rate of premature and sick term infants who are successfully able to breastfeed at the time of discharge and maintain breast feeding longer after discharge. This would allow premature infants to acquire the many benefits of breastmilk as well as contribute towards the strengthening of the maternal-infant bond that breastfeeding has been shown to enhance.
Interventions
DEVICE
taVNS soterix device
Soterix is a custom modified, FDA-cleared electrical stimulator that meets the criteria of the FDA for investigational use. Neoleads will be placed in order to deliver electrical stimulation using microcurrent (\<2.5mA) with breastfeeding, on with sucking and swallowing and off with rest for 5 feeds per week for 2 weeks.
Primary outcome measures
Adequate volume transfer during breastfeeding
Time frame: 2 weeks
Measured by pre- and post-feed weights (grams)
Infant's ability to sustain breastfeeding for a length of time
Time frame: 2 weeks
Average length of active feeding at the breast (minutes)
Targeted motor learning of skills involved in breastfeeding
Time frame: 2 weeks
Demonstration of successful latch, suck, and swallow techniques by the infant per LATCH scoring (L= latch, A= audible swallowing, T= type of nipple (inverted, flat, everted after stimulation), C= Comfort of mother during feed, H= Hold/positioning of infant), scoring 0-10 (2 points per question) with 10 being the highest and optimal score.
Targeted motor learning of skills involved in breastfeeding
Time frame: 2 weeks
Demonstration of successful latch, suck, and swallow techniques by the infant by study personnel descriptions (Only lactation consultants are trained to obtain LATCH scores, thus when no lactation consultant is present, study personnel will simply describe infant's demonstrated skills during the session without a specific measurement tool)

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.
