Cord Milking Impacts Neurodevelopmental Outcomes in Very Low Birth Weight Infants (Cordmilking)
Neurodevelopmental Outcomes of Cord Milking in Preterm Infants: Randomized Controlled Trial
Premature birth is a major risk factor for perinatal brain damage and cerebral palsy (CP) with 47% of all CP cases occurring in infants with birth weight less than 2500 g. CP has life-long neurological consequences that affect quality of life for the patient. In the last 2 decades, improvements in neonatal intensive care have improved survival of VLBW infants significantly. This increased survival of VLBW infants poses new challenges towards developing novel treatments and interventions to decrease neurodevelopmental impairment and CP. While it is common for extremely preterm infant to survive at 23 weeks of gestation, the neurologic consequences range from learning difficulties and cognitive defects to severe disability and cerebral palsy. Currently prenatal neuroprotective agents such as corticosteroids are utilized whenever a preterm birth is anticipated. However, there are no proven postnatal interventions to prevent brain damage and cerebral palsy in VLBW infants.
Many recent studies show that delaying umbilical cord clamping (DCC) may improve hemodynamic stability and decrease intraventricular hemorrhage (IVH) in preterm infants. A decrease in incidence of IVH has a conceivable prospective benefit of decreasing brain injury and improving long-term outcomes. Based on these findings, the American College of Obstetricians and Gynecologist and American Academy of Pediatrics endorse that DCC may benefit the preterm infants. However, these recommendations have not been adopted by most obstetricians in USA. The main concern regarding the practice of DCC is the care delay in initiating resuscitation and providing the needed care to this vulnerable population.
Therefore, as an alternative to DCC, method of cord milking (CM) has been developed to provide cord blood transfusion to premature infants. CM offers a more practical alternative to delayed cord clamping that may provide the same benefits without the need to delay resuscitation. However, there are very few studies of CM in VLBW infants and there is no evidence demonstrating long-term neurological outcomes and CP after CM.
The investigators hypothesize that cord milking in VLBW infants will result in improving cerebral oxygenation, function and result in improved long-term neurodevelopmental outcomes at 2 years of post-menstrual age. Premature infants born at less than or equal to 32 weeks gestation age will receive cord milking after cutting versus standard care of immediate cord clamping.

Detailed Description
Primary Aims
To Measure:
- Cerebral oxygenation and function (aEEG abnormalities) in first 24 hours of life
- Neurodevelopmental outcomes at 18 - 24 months PMA Secondary Aims
1. Assessment of Improved transition: Delivery room resuscitation, Apgar scores, acidosis from cord gas or first hour blood gas 2. Neurological injury assessment: IVH/PVIH/PVL on head ultrasound on day #3-5 and day #7-14, and at 36 wk PMA, MRI at 36 wk CGA 3. CVS response: Blood pressure and ionotropic support in first 3-5 days 4. Hematological assessment: Hemoglobin, Hematocrit of admission, and first 72 hours of life, need for phototherapy and highest bilirubin level in first 7 days, blood transfusions needed till 36 wk PMA 5. Gastrointestinal protection: Necrotizing enterocolitis till 36 wk PMA In this pilot study, we plan to enroll 15 VLBW infants in each group (n=30) from Mattel Children's Hospital and Santa Monica Hospital labor and delivery. Data pertaining to primary and secondary aims will be obtained from EMR. Follow up utilizing Bayley's scores of infant development (BSID III) will be scheduled at 18-22 months PMA

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Cord Milking
The research team member will untwist the cord, and hold it in a vertical position.
The cord will then be milked twice towards the abdominal insertion of the cord.
The cord will be cut 1 inch above the abdominal wall.
After milking for exact measurement of the cord will be obtained.
|
For infants in the cord milking group, the cord will be clamped at the longest distance possible and neonatal team will bring the infant to the resuscitation table for further care.
The clinical care will be provided by the clinicians taking care of the infant.
The research team will be trained and be responsible for requesting the obstetrician in advance to provide the maximum length of umbilical cord.
|
No Intervention: Observational
Observational infants will receive usual care with immediate cord clamping by the delivering obstetrician.
The time of cord clamping will be recorded for both groups using a timer.
