Infant Massage for Lymphedema and Comfort in Preterm Newborns

Preterm infants born before the 37th week of gestation frequently encounter health challenges due to immature physiological systems, with lymphedema being a significant clinical concern precipitated by circulatory insufficiency and prolonged immobilization in the Neonatal Intensive Care Unit (NICU). This condition is characterized by abnormal fluid accumulation that, if untreated, can lead to chronic pain, infection risks, and developmental delays. While manual lymphatic drainage is the standard for adults, its application in preterm infants is limited due to skin fragility, and surgical options carry substantial risks. Consequently, there is an urgent need for non-invasive approaches to facilitate fluid movement in the absence of natural physical activity.

Although infant massage is known to enhance weight gain and reduce stress, its specific efficacy in mitigating immobilization-related lymphedema through mechanical drainage has not been rigorously examined. This randomized controlled trial aims to evaluate the clinical effectiveness of infant massage as a non-invasive intervention for reducing lymphedema symptoms and enhancing comfort levels among preterm neonates. The study will be conducted at a Level III NICU, involving preterm infants hospitalized for a minimum of two weeks who meet specific eligibility criteria, including hemodynamic stability and a diagnosis of lymphedema.

Participants will be randomized into an intervention group receiving standardized massage therapy and a control group receiving standard care. The intervention consists of a 15-minute daily massage regimen applied for 14 consecutive days, focusing on affected extremities and lymphatic regions using an oil-free, hypoallergenic formula. Primary outcomes, including extremity circumference measurements (wrist, elbow, ankle, knee) and pitting edema grading, will be assessed on Day 0, Day 7, and Day 14. Secondary outcomes involving neonatal comfort will be evaluated using the Premature Infant Comfort Scale (PICS). The study seeks to determine whether mechanical stimulation can effectively mitigate fluid accumulation and alleviate physiological distress in this vulnerable population.

Inclusion criteria

To ensure a homogenous and clinically stable sample, infants meeting the following criteria will be recruited:

• Clinical diagnosis of lymphedema.
• Hemodynamic and clinical stability.
• No current or recent (within 24 hours) administration of analgesic or sedative medications that could mask comfort assessments.
• Intact skin integrity with no contraindications for topical massage.
• Absence of congenital heart disease or neurological disorders (antenatal or postnatal diagnosis).
• No immediate requirement for endotracheal aspiration.
• Requirement for only non-invasive respiratory support (e.g., nCPAP).
• Provision of written informed consent by the legal guardians (parents).

Exclusion criteria

Infants will be excluded if they present with:

• Major congenital anomalies.
• Severe respiratory, cardiac, or neurological instability during the study period.
• Any acute medical contraindication identified by the attending neonatologist.
