The Science - The Zaky ZAK®

This page includes only studies that utilized The Zaky ZAK®.

For evidence and publications about skin-to-skin or kangaroo care visit www.kangaroo.care.

Summary:
The studies on The Zaky ZAK® demonstrate its effectiveness in improving duration, frequency, and parent satisfaction in the NICU. Key findings include enhanced cognitive and autonomic development, improved neurophysiological outcomes, increased parental confidence, and reduced unplanned extubations. The Zaky ZAK® is instrumental in promoting skin-to-skin contact, reducing stress, and supporting the release of oxytocin in infants, contributing to better neurobehavioral patterns. These studies emphasize its importance of providing safety and immediate and quiet access while holding infants in neonatal and developmental care.

Implications for Learning and Autonomic Nervous System Function in Infants With Critical Congenital Heart Disease (CCHD)

Conclusions:

Findings suggest improvements in cognitive and autonomic development in 3-month-old infants with CCHD who received neonatal Skin-to-Skin-Care.

Learning and autonomic function results in infants with CCHD who had not received SSC suggest reduced capacity to muster the physiologic resources to carry out this cognitive task. Findings provide preliminary evidence in support of implementation of SSC with infants with CCHD and support additional research.

Every mom/baby dyad used The Zaky ZAK® (previously known as Kangaroo Zak®) during skin-to-skin contact sessions, as acknowledged and described on page 3 of the paper.

by Jillian S. Hardin, Nancy Aaron Jones,  Krystal D. Mize, Melannie Platt

Findings suggest Kangaroo Care may garner favorable neuro-maturational and neurobiological outcomes for dyads.

Full-term (> 37 weeks GA) babies and mothers that were assigned to the Kangaroo Care Group were given The Zaky ZAK® (Kangaroo Zak®.)

"Improving The Frequency And Duration Of Skin To Skin Holding [with The Zaky ZAK®] To Promote Parental Confidence In NICU"

by Elizabeth Jeanson PT DPT; Sheri Fischer, MSN RN CBC; Andrea Bunn DNP RN; David Munson, MD; Jessica Schnyders BSN RN; Nate Harris BSN RN

Sanford Improvement Academy selected The Zaky ZAK® as part of their Kangaroo Care implementation. The goal was to improve parent confidence, duration, and frequency by 20%.

Here are the results:

• Parental confidence increased by 62% on the PPCI
• Duration of STS holding increased by 62%
• Frequency of STS holding increased by 26%
