I thought I would start off my series of posts with one of the most basic reasons we do Kangaroo Care.
Thermoregulation is the process of maintaining an infant’s temperature within normal range. Thermoregulation is extremely important for the newborn (term or preterm). An infant’s body surface area is 3X greater than an adult’s, causing them to potentially lose heat rapidly, up to 4X faster. When cold stressed, infants use energy and oxygen to generate warmth. Oxygen consumption can increase by as much as 10%. Thermoregulation of the infants allows them to conserve energy and build up *reserves”.
What Happens When An infant Is Placed Skin to Skin?
When the term infant is placed skin to skin at birth, the mother’s breasts immediately start to warm and conduct heat to the infant, helping to maintain normal blood sugar levels due to the infant not having to use their own brown fat to stay warm (Bergstrom et al.,2007;Bystrova et al.,2007;Ludington-Hoe et al.,2000,2006) (Chantry,2005;Christensson et al.,1992).
Kangaroo Care maintains a Neutral Thermal Environment (defined as the ideal setting in which an infant can maintain a normal body temperature while producing only the minimum amount of heat generated from basal life-sustaining metabolic processes).
In our unit, any infant that needs an incubator to maintain their temperature can only come out to be held by Kangaroo Care instead of being bundle held. To help maintain thermoregulation we make sure the infant and parent are in a draft free area, and use 2-4 layers of blankets over the infant (you can always remove a layer if needed). Infants weighing less than 1000gms should wear some type of head cap and monitor them using the incubator’s temperature probe. Remember too, we don’t want any bras or clothing between the infant and the mother, fabric will interfere with the conductance of heat from mother to infant (Ludington-Hoe et al.,2000).
One of the interesting things about KC and thermoregulation is if a mother holds twins in KC each breast works independently to warm each infant (Ludington-Hoe, et al.,2006). Triplets? Not sure, but our mothers hold their “trips” together all the time and we have had no issues.
Now, how about the father? Does he thermoregulate like the mother? With mothers you have what is called Thermal Synchrony (maternal breast temperatures changing in response to the infant’s temperature) (Ludington-Hoe, et al.,1990;1994,2000) where the fathers chests will warm up when the infant is placed in KC but will not cool down (Maastrup & Greisen, 2010). We don’t have any issues with our fathers overheating, just lots of hair to be picked off the infant after!
Hi, my name is Diane Schultz and Michael has asked me to write a series of posts on his blog about Kangaroo Care (KC). Seeing as I am one of the Champions (they call you that, but sometimes the word begins with a B) for KC in my unit, I was thrilled. I thought I would begin with an introduction as to why I want to write about this.
I have been a Neonatal Nurse for 29 years working in the NICU at St. Boniface Hospital in Winnipeg. I felt that I had always given good care to the families but did not really make connections with them.
I was fortunate enough to meet Dr. Susie Ludington about 10 years ago at an Academy of Neonatal Nursing conference. She was a general session presenter and was speaking about Kangaroo Care. The first thing she said was “My goal is Kangaroo Care 24/7”. All I could think of was WTF!? I would have to listen to this Nutbar for an hour? Our unit had been doing KC for years but only occasionally and usually the parent would ask for it, we certainly did not promote it or do it with our more fragile infants.
After listening to Dr. Ludington present, my world changed. What she said hit a cord; she presented benefit after benefit with rationale and evidence that made complete sense to me. I felt guilty I had not been doing this at work and guilty that I had not held my own daughters this way. I am now lucky to be able to call Dr. Ludington a friend, and know she has changed my life.
Now, there is a lot of evidence out there touting the benefits of KC, but the real way to understand and believe in it is to do it. KC creates its own evidence. Every time I bring out a medically fragile infant to be held in KC, I know that this is the right place for that infant to be: with their parent being held. You can see the relaxation on all of their faces (decreasing cortisol), the infant is able to go into a deep sleep (promotes brain maturation), and the family is able to connect in the best way possible. I feel KC is as important as anything else we do at the bedside and is an extremely necessary therapy.
Promoting KC in my unit has benefited me at so many levels; I believe it has actually saved my career and given me a focus that I didn’t have before. You can’t help but make connections with your families, and these families are able to make connections with their little ones. KC is also a very important part of Family Integrated Care, as this is something that the family can contribute to their child’s care.
I also couldn’t be more proud of my unit; the staff I have the pleasure to work with are some of the best health care professionals around. They make every effort to bring our fragile infants out for KC and it has become part of our culture in our NICU. KC happens in our unit with almost all of our infants, the only exceptions being actively cooling babies and infants with chest tubes. We have also created a Standard Work Protocol so all medically fragile infants come out the safest way possible without creating extra stress on the infant or family.
In my series of posts I will present the many benefits of KC for infants and their families and share some of my experiences. I hope you will be able to take something away from this, begin to try KC in your own unit, and create your own evidence.
