History of Kangaroo Care
Kangaroo care was invented in the late 1970s by Dr. Edgar Rey in Bogota Colombia as a response to the extremely high death rate of preterm babies at his impoverished hospital.
Rey’s NICU department did not have enough incubators for all of the preterm babies and few of them survived. Asking for money probably wouldn’t get him anywhere so he started thinking creatively.
He reasoned out a solution that would change the fate of preterm babies all across the world.
What are incubators for, he asked himself? To mimic a mother’s womb by offering the baby constant warmth, nourishment, and oxygen. Well, Rey thought, a mother herself could probably offer the same if not superior incubation. He may have not known exactly why this was true at the time, but indeed, it was true. The method was so successful that it spread to other third world nations and has since been studied extensively and even adopted by many developed nations.
Kangaroo Care Methods
Babies are placed skin to skin against a parent’s chest 24 hours a day (probably less in developed nations where incubators are available). The baby is kept upright to prevent reflux and apnea. They wear a hat and blanket on their backs. Those that need it will receive an IV and oxygen right on the mother’s chest. As soon as the baby is able to start sucking, it will nurse.
Conditions are said to be fair to return home if the baby is pink, can suck, and breath on its own. This generally happens much faster in kangaroo cared infants than in conventionally incubated infants. Sometimes preterm babies and their parents go home the next day.
Benefits of Kangaroo Care
- A woman’s breasts modulate temperature, responding to the thermal needs of the infant, giving the infant the exact temperature it needs to stay warm all the time. (This even works with twins! Each breast has the ability to maintain different temperatures.)
- Kangaroo care infants sleep more. Hence, they grow and develop faster. According to Dr. Ludington, author of Kangaroo Care: The Best You Can Do to Help Your Preterm Infant, babies sleep twenty to twenty-two hours per day in their last six weeks in the womb. In contrast, she says that NICU babies get about 2 hours of quality sleep per day.
- There is greater opportunity for breastfeeding and parent/child attachment in kangaroo cared infants.
- Mothers and fathers of preterm infants are better equipped to manage the care of their tiny baby and more confident in how to handle the challenges of caring for such a small person.
- The mother’s heart rate and breathing help to regulate a premature baby’s heart rate and breathing.
Holly Richardson said in an article entitled Kangaroo Care: Why Does It Work? published in Midwifery Today,
“Researchers have gained significant insight into what happens to an infant’s brain during kangaroo care. Any baby’s heart rate and respiratory rates can be plotted as a sort of artistic drawing. Because premature infants lack the ability to coordinate their breathing and heart rates, the rates “plot out” as chaotic. This means with increased demand on the cardiovascular system, as with crying or fussing, the system does not respond with a related increase in cardiac output. In other words, the baby’s respiratory rate may increase while crying, but the heart rate does not. As preemies mature, these rates become synchronized, or “coupled,” resulting in an orderly drawing when the rates are plotted together. The drawing no longer looks random.
In infants in kangaroo care, researchers found that coupling takes place after only ten minutes. This hardly seemed possible because it equaled four weeks of brain development in the “normal” preemie. As researchers studied brain wave patterns of infants in kangaroo care, they found two significant things. First, there was a doubling of alpha waves—the brain wave pattern associated with contentment and bliss. Second, they found that “delta brushes” were occurring. Delta brushes happen only when new synapses are being formed. So holding the infant skin-to-skin allows his or her brain to continue its work of developing neural synapses.”
Why Incubators Aren’t the Best Option
- Incubated babies are usually not warm enough and preemies must make heat with their own bodies and use their own calories to regulate temperature.This takes a lot of energy that they should be expending on brain development.
- Premature infants in incubators have high rates of irregular heart rates and sleep apnea.
- Premature infants are alone with no skin to skin contact most of the time. Dr. Ludington says that, “Separation is not biologically normal,” hence the irregularities in sleep, breathing, heart rate, and neural brain development.
- Babies receive an IV nutrition and hydration drip while in the incubator. While preterm infant formula is a different formulation than other infant formulas it still contains soy oil, carageenan, non-fat milk, and corn syrup solids.
- The liquid medications babies receive can contain sorbitol, ethanol, aspartame, flavorings, and food colorings. Sorbitol causes nausea and malabsorption.
- Potential infant drug addiction.
- Preterm infant diuretics can contain enough ethanol to get a baby drunk.
Is Preterm Labor Really So Bad?
All of this makes me wonder, do preterm babies suffer so many hardships such as cognitive difficulties later in life because they are preterm? Or is it because preterm infant care is not very good? Infants who don’t sleep enough, don’t absorb nutrients well, don’t feel safe, aren’t warm enough, and are subject to the chemicals in preterm infant drugs are not given the conditions necessary to develop properly.
How Early is Too Early for Preterm Home birth?
The choice to have a baby at home when it comes before 38 weeks gestation is a decision only the parents can make. Many midwives won’t deliver babies any earlier than 36 to 37 weeks, though some will attend an even earlier preterm birth.
The greatest risk for premature babies is respiratory problems, though when they are delivered vaginally, the risk decreases significantly. Midwives generally bring oxygen to births and if further support is needed, the baby can be transported to a hospital via ambulance, which can administer oxygen.
Most babies older than 28 weeks gestation have digestive tracts mature enough for milk feedings, however, they may not be mature enough to suck until 32 weeks gestation, making an IV absolutely necessary.
I think most of us are led to believe that preterm infants (before 38 weeks gestation) cannot survive outside of a hospital. This is often simply not the case and the use of kangaroo care around the world proves it. However, when a baby is at risk for complications, having a hospital nearby can be a life saver.
