Irregular Breathing in Newborns: What You Should Know

By

On October 27, 2020

In Neonatal Care, Newborn Screening, Newborns

New parents may be alarmed when their newborn has trouble breathing. Babies often breathe irregularly in the hours following their birth and in the first few days of life. Here is a brief overview of irregular breathing in newborns — and what warrants a visit to the pediatrician.

Normal Breathing in Newborns

Newborns typically breathe through their nose rather than their mouth and have smaller breathing pathways. These smaller pathways mean babies can’t take in as much as oxygen and breathe more rapidly. Babies usually take between 30 and 60 breaths per minute while they are awake and 20 breaths per minute during sleep. In comparison, an adult breathes between 12 and 20 times per minute.

It is normal for a baby to take several rapid breaths and then pause for several seconds. This is especially true in the newborn days when the respiration system is still developing. Most breathing irregularities typically resolve within the first few months of life.

Breathing Problems in Babies

Becoming familiar with a baby’s normal breathing pattern can make it easier for parents to distinguish any problems that occur. Some of these problems may include:

Barking cough and/or hoarse cries

Croup often hits in the middle of the night and terrifies parents. It is marked by a barking, seal-like cough, hoarse cries, breathing difficulties and/or a fever.

Whistling noises

Whistling sounds are often due to blockages in the nostrils. Babies breathe through their nostrils rather than their mouths. Any blockage in the nostrils due to allergies or a cold can make breathing difficult.

Wheezing

Wheezing can be a sign of a more serious condition in babies. When the airways become constricted due to asthma, pneumonia or respiratory syncytial virus (RSV), the baby isn’t able to draw enough oxygen during each breath.

Fast-paced Breathing

Fast-paced breathing is often accompanied by an elevated heart rate. Fluid in the airway from pneumonia or another infection could be the cause.

When to See a Doctor

Breathing problems are common during cold and flu season. An estimated 15 to 29 percent of all hospital admissions in babies are due to breathing problems. If parents notice any changes in their child’s breathing, they should notify a doctor immediately. Call 911 or go to the nearest emergency room if:

  • the baby stops breathing for more than 20 seconds
  • a blue color is noticed in the lips, toenails or fingernails
  • the muscles in the neck pull in during breathing

Taking care of a child when their breathing is irregular can be very stressful. Learning to watch for the signs and knowing when to alert the child’s pediatrician can help keep newborns safe and healthy as they grow.

Neonatal Septal Defects: An Overview

By

On July 30, 2020

In Child Health Care, Neonatal Care, Newborns, Research, Uncategorized

Ventricular septal defects, or VSD, refers to an opening in the wall that separates the lower ventricles of the heart. The condition occurs naturally in neonates at a rate of one out of every 250 to 330 births. Normally, the hole closes before the infant is born, which prevents oxygenated blood from combining with unoxygenated blood.

 

Under normal circumstances, blood enters the right side of the heart and continues into the lungs to receive oxygen. The blood then travels to the left side of the heart and is pumped through the body. But, when VSD occurs, more blood enters the lungs than normal, which stresses the heart and the lungs.

 

If the hole is small, physicians might hear a murmur when listening to the heart using a stethoscope. Otherwise, the child exhibits no symptoms. The opening is not large enough to add stress. However, if the hole is large, the infant breathes faster and harder than normal secondary to the stress on the heart and lungs. They may also exhibit difficulties when suckling and gasp for breath. Symptoms may occur shortly after the birth of the child. Or, the signs may not appear until weeks later when the lungs become hypertensive. If the child does not receive medical intervention, the lungs and blood vessels may endure irreversible damage.

 

Small hole defects commonly close without intervention. However, if the defect is deemed to be large, surgical repair is required. The procedure used depends on the size of the defect. Some are easily corrected in a cath lab. If the hole is not extremely large, surgeons may simply sew the detector closed. Other options include surgically applying a fabric or tissue patch over the hole. The patch is later naturally covered by normal tissue that lines the heart.

 

Banding the pulmonary artery is another option, which reduces the amount of blood that flows into the lungs. The scheduled surgery takes place anytime from early infancy into later childhood depending on the severity of the condition and accompanying symptoms.

 

Once the defect is medically corrected, the infant or child may resume a normal life. A pediatric cardiologist may advise that the child undergo periodic evaluations to ensure the ongoing health and detect possible complications. In rare cases, a heart valve may develop a leak once the child is older, which also requires intervention.

COVID-19’s Potential Impact on Newborns

By

On July 6, 2020

In Child Health Care, Neonatal Care, Newborn Screening, Newborns

COVID-19 produces victims of all ages. Concern grows for pregnant women and unborn children. Facilities around the world continue studying the microbe and reveal their findings thus far. Some studies suggest that infants born to mothers having the virus have a high risk of suffering ill effects.

From January 20 to February 5, nine women gave birth to 10 infants in five different hospitals in China’s Hubei province. Eight of the expectant mothers tested positive for COVID-19 before delivery. One mother tested negative. However, a fever and a CT scan of her chest revealed pneumonia that could not be contributed to any other underlying cause but the virus.

The women suffered a variety of prenatal complications that included intrauterine distress, ruptured members prior to the onset of labor, amniotic fluid abnormalities and placenta previa. Seven of the mothers delivered their babies via cesarean section. The other two women had normal vaginal deliveries.

The mothers were treated with Tamiflu or a combination of the antiviral plus interferon following delivery. After birth, all of the infants were tested for COVID-19 via oral swabs. All of the tests were negative. Four of the babies were full-term and six were premature. All of the infants exhibited unusual symptoms that included fevers, difficulty breathing, elevated heart rates, inability to feed, vomiting, gastric bleeding and bloating from liver malfunction. Seven of the infants exhibited abnormal chest X-rays. Two of the premature babies died nine days after birth.

A team of researchers from Northwestern University in Illinois recently discovered that the virus damages the placenta in expectant mothers. The study involved 16 pregnant women who tested positive for COVID-19. Following delivery, the placenta tissues were evaluated. The team discovered that the blood vessels within the placentas exhibited abnormal development or were otherwise damaged. However, all of the infants tested negative for the virus and were in reported good health.

Researchers from the University of California San Diego expanded the MotherToBaby program to gain a better understand the short- and long-term effects of the virus on expectant mothers and infants. Previously, the program was designed to evaluate medications and environmental factors that might affect pregnant women, newborns and breastfeeding.

The study will involve the examination of medical records and phone calls to women who volunteer for the research. The program also includes monitoring the neurological development of children to determine possible emotional, learning or memory issues.

A Closer Look at Neonatal Polycythemia

By

On June 1, 2020

In Neonatal Care, Newborns

Polycythemia occurs when bone marrow is manufacturing too many red blood cells, thereby increasing the volume percentage of red blood cells in the blood. It can also be caused by a low plasma count in relation to blood cells, causing an imbalance. These excess cells, in turn, thicken the blood, which slows down the overall blood flow leading to more serious issues, such as blood clots. Polycythemia is essentially the opposite of anemia, which is when there are too few blood cells being produced. 

Neonatal is a term used to describe babies within the first 28 days of life. Neonatal polycythemia is diagnosed when a baby’s blood is composed of more than 65% red blood cells. This is a common problem with newborns, but that number is expected to decrease within a few hours if everything is normal. 

Some babies who are at a higher risk include those who are born small for their gestational age, babies who are post-term, infants of mothers with diabetes, twin-to-twin blood transfer in utero, low oxygen levels in fetal blood, and babies born with chromosomal abnormalities. 

It can be hard to diagnose this condition when babies are first born, because, aside from a high blood viscosity, babies might be asymptomatic before showing any metabolic changes due to this disorder. Samples should be taken from a largely free-flowing blood vessel in order to get an accurate hematocrit result. Signs that blood is affected include poor blood flow returning to a site after pressure is applied (peripheral perfusion), and blood having a ruddy, dusky appearance. There are also other clinical symptoms that include lethargy, irritability, tremors, seizures, lack of interest in feeding, hypoglycemia, rapid breathing (tachypnea), and bluish/grayish skin coloration (cyanosis).

There are several other conditions that share similar symptoms with neonatal polycythemia, which is why it is vital to rule them out before attempting any course of treatment. Some conditions that are similar include hypoglycemia, neological dysfunction, renal failure, or respiratory issues. Once a firm diagnosis is confirmed, there is a recommended course of action. 

Not all babies require treatment, but if there are signs of metabolic distress, the first priority is to lower the hematocrit by performing a partial exchange transfusion (PET). Either a saline solution may be used or a 5% protein solution. Saline is the preferred material because it won’t risk infection and has a better price point. It is strongly advised to avoid fresh frozen plasma because studies have shown a correlation between its use and necrotizing enterocolitis.

Top Pregnancy Myths: 2020

By

On April 17, 2020

In Neonatal Care, Newborns, Research

Some of the information expectant mothers receive is often based on myths or old wives’ tales. Dispelling the myths may bring comfort and reassurance in addition to ensuring the health of the expectant mother and growing infant.

You’re Eating for Two

For decades, women were encouraged to substantially increase their dietary intake in order to ensure they were consuming enough nutrients for the growing infant. However, overeating leads to obesity, which leaves the mother and baby at risk. Being overweight increases the chances of developing gestational diabetes or hypertension. The excess weight also stresses the cardiovascular system. Health care providers suggest that increasing daily calorie intake by a mere 200 to 300 calories is more than sufficient to ensure a healthy pregnancy.

Belly Size and Shape Reveals Gender

Physicians rebuke the belief that external appearance correlates with the baby’s gender. Some women carry the baby high while others carry it lower. However, the difference is often equated with genetics and physical characteristics and not infant gender.

Moisturizing Prevents Stretch Marks

Cocoa butter has long been touted as being one of the solutions to prevent stretch marks. While moisturizing preparations are good for the skin, they do not prevent the physiological effects that a growing infant causes on external skin. Women develop varying degrees of marks depending on genetics and the extent that the abdomen needs to stretch to accommodate the infant.

Stay Away from Cats

There is no reason why expectant mothers cannot have and care for a feline companion. The danger lies in changing the litter box. Feline waste products commonly contain a parasite that has the potential for causing toxoplasmosis. While the mother may or may not experience flu-like symptoms, the illness has the potential of becoming serious in infants. Best to leave litter box duties to someone else. The disease can also be contracted by eating undercooked meat or unwashed fruits and vegetables.

Coronavirus and Pregnancy: What to Know

By

On March 24, 2020

In Child Health Care, Neonatal Care, Newborns, Research

Historically, viral illnesses become more serious in the very young, the elderly and in individuals having a weakened immune system. Given that victims of all ages have become infected with the coronavirus, many are understandably concerned about the effect the illness may have on expectant mothers.

Pregnancy and Covid-19

The World Health Organization reports that in a study of 147 pregnant women, eight percent developed more severe forms of the illness. One percent required critical care.

A study of nine afflicted women who gave birth indicated that none of the infants tested positive for the virus. But, the women all became infected during the last trimester of pregnancy. It remains yet unknown how the virus might affect a fetus during the early months of development.

Another study involved 10 newborn infants who developed serious forms of the illness. According to a physician from the Northwestern University Feinberg School of Medicine, the amniotic fluid, breast milk, and cord blood were tested. But, all of the fluid was negative for Covid-19. So, physicians do not believe that the illness passes from the mother to the developing infant. Theories revolving how the babies became infected include that the women may not have undergone testing and found to be afflicted before delivery. The babies may have come in contact with their infected mothers shortly after birth.

An obstetrician affiliated with the American College of Obstetricians and Gynecologists advises that pregnant women should undergo testing at their initial appointment and separated from patients who tested negative. Pregnant women are advised to use the same precautions recommended for the general public.

About Covid-19

After exposure, individuals may develop symptoms in two days to two weeks. The majority of afflicted individuals suffer symptoms that are equated with the common flu. The experience may include fever, generalized fatigue and upper respiratory symptoms. Others suffer muscle aches and diarrhea. The World Health Organization reports that the virus causes serious illness in one out of every six patients. More severe cases exhibit difficulty breathing and shortness of breath. Individuals experiencing more serious symptoms are advised to seek medical attention.

Scientists recently revealed that the virus has two strains, one of which is more aggressive than the other. Health care providers also report that it is possible for individuals to suffer a relapse, which is often more serious.

Transmission occurs through airborne droplets or coming in contact with infected animals, surfaces or fecal matter.

Exploring Current Neonatology Trends

By

On February 24, 2020

In Neonatal Care, Newborn Screening, Newborns

As technology has aided in advanced medical care over the last few decades, neonatology treatments and care options have improved and grown in number. Maternal mortality prevention is the goal of neonatology, and these trends are helping caregivers achieve their goals.

Here are a few prevailing neonatology trends to keep an eye on in 2020. 

More Resources for Practicing Neonatologists

There are more available than ever for practicing neonatologists, primarily because of the growing need for more highly capable practitioners. The increasing number of mothers who are addicted to drugs or alcohol, increasingly poor nutrition, diabetes and high blood pressure are some driving factors of this trend. Neonatologists and medical professionals with similar disciplines can connect with the Section on Neonatal-Perinatal Medicine (SONPM) website, which is an affiliate of the American Academy of Pediatrics.

Preventing Neonatal Sepsis

Neonatal sepsis is another condition that affects millions of children every year. This is a bacterial bloodstream infection (BSI) that is potentially life-threatening to babies, especially those of low birth-weight. This can happen quite unexpectedly and for many reasons, including pneumonia, meningitis and gastroenteritis. This makes the detection of neonatal sepsis before it fully takes hold of the child imperative. Treatments can be applied speedily to rid the bloodstream of the infection when it’s detected early.

Improving Communication with Parents

When your newborn child is in the intensive care unit (ICU), it can be the most trying experience of your life. To reduce the stress and anxiety that can come from not knowing, neonatologists are trying to be more transparent and open to communicating with the parents. In cases of premature infants, this can mean encouraging skin-to-skin contact between the parents and the baby. Research has even shown the babies’ vital signs tend to suddenly improve when they are being held by their parents. The relief the parents feel to know their child is in good care is an added benefit.

With the help of specialized supplements for newborn babies, malnutrition is no longer a problem. However, optimizing the use of breastmilk is a tradition that most neonatologists are trained to believe in. Breastfeeding is encouraged, but when this can’t happen, donor milk is promoted as an option before other methods for nutrition aid are considered.

Neonatal Necrotizing Enterocolitis: What is It and How is it Managed?

By

On January 31, 2020

In Neonatal Care, Newborn Screening, Newborns, Research

Necrotizing enterocolitis, or NEC, is a serious intestinal affliction that affects one in every 2,000 to 4,000 infants. The disease process more commonly occurs in premature babies born before the 32nd week of gestation. But, the disorder has been found in babies born at full term who also have heart anomalies or other health conditions. NEC develops when the large or small intestine becomes inflamed or injured by naturally occurring bacteria. The affected site may eventually weaken, which enables the bacteria to pass through and cause a life-threatening systemic infection.

NEC Causes

Researchers have not determined a specific cause for the disease development. However, there is a theory that a number of factors contribute to the problem.

  • Abnormally high level of intestinal bacteria
  • The presence of invasive bacteria or viral colonies that instigate an infection
  • Insufficient blood flow and oxygen to the intestine
  • Intestinal lining injury
  • Baby formula
  • Underdeveloped intestines

Necrotizing Enterocolitis Signs and Symptoms

Infants develop symptoms within the first month after birth. As the disorder progresses, the infant’s abdomen swells, becomes red and tender. The child may become constipated or pass dark, bloody diarrhea. The infant may vomit green bile. The baby’s body temperature, heart rate, blood pressure, and respiratory rate decrease. The infant becomes lethargic.

NEC Treatment

Once diagnosed, feedings are temporarily discontinued. The infant receives fluids and nutrition via IV supplements. A surgeon inserts a gastric or a nasogastric tube into the stomach, which enables air and fluid to escape. The presence of infection, or to prevent infection, requires antibiotic treatment. The baby undergoes frequent abdominal exams and X-rays to monitor progress. The child’s stools are monitored for stool changes. Blood tests determine anemia or infection. In severe instances, the child may require surgery.

If the child’s condition worsens or does not respond to treatment, surgery may be necessary to repair any perforation or to remove dead tissue. In the event that a large area of the intestine suffers damage, the surgeon may reroute the remaining tissue to an opening in the stomach, which is known as a stoma.

When the medical team deems that the infant’s condition is improving, they typically recommend that the child receive breast milk. Breast milk boosts immunity, is easier to digest and promotes the growth of healthy bacteria in the gastrointestinal tract.

In Child Health Care, Hiking, Neonatal Care, Newborns

Neonatal jaundice is caused by unconjugated bilirubin in a newborn’s body. It’s presently the most common condition that requires medical attention or hospital readmission for newborns. This condition can have dire consequences, so early detection and treatment is crucial.

Symptoms Of Neonatal Jaundice

It’s common practice for hospitals to check newborns for jaundice before release,however parents should be aware of what to look for. Some symptoms of jaundice in infants include:

  • Yellow sclera (white part of the eyes)
  • Yellow skin, especially the abdomen and limbs
  • Baby is hard to awaken or lethargic
  • Baby is not gaining weight

If these symptoms appear after a child has been sent home from the hospital, it may be advisable to bring them back in for medical treatment.

Causes Of Neonatal Jaundice

Jaundice in infants can often be caused by the liver being underdeveloped. This leads to an inability for the liver to properly break down the bilirubin in their bodies. Besides immature livers, some other causes of this condition include:

  • Blood infection (sepsis)
  • Viral or bacterial infection
  • Malfunction of the liver
  • Deficient enzymes
  • Internal bleeding
  • Abnormal red blood cells

If symptoms of jaundice appear, the child will need to be checked for underlying causes to form a treatment plan.

Factors That Increase Risk Of Neonatal Jaundice

There are some factors that make jaundice more likely in infants. These factors include:

  • Bruising during birth
  • Mother and child’s blood types are different
  • Birth before 38 weeks
  • Breastfeeding difficulties

If a child has these risk factors, their parents and medical team will need to monitor them.

Treatment Of Neonatal Jaundice

To avoid acute or chronic complications, jaundice needs early treatment. Some ways it can be treated include:

  • Light therapy
  • Intravenous immunoglobulin
  • Exchange transfusion

These methods focus on diluting pathogenic antibodies in the child’s blood that cause jaundice or, in the case of light therapy, help the child’s body to more easily break down and excrete the excess bilirubin.

Diagnosing and Addressing Neonatal Apnea

By

On October 3, 2019

In Neonatal Care, Newborns

Apnea is a term defined as the cessation of breathing for longer than 10 to 15 seconds. While this can happen at any age, it typically affects infants aged two to four weeks until six months.

It is particularly seen in premature infants born around 28 weeks due to their underdeveloped respiratory systems. It happens when the brain and spinal cord do not mature, obstructing breathing

When apnea develops, it can have many causes. The most common links found in neonatal apnea are an infection, neurological, cardiovascular, pulmonary, metabolic, temperature regulation and maternal drug use.

Types of Apnea

There are three main types of apnea. These are central, obstructive and mixed apnea.

Central apnea is when there is no signal of breathing transmitted to the respiratory muscles, causing the system to not respond due to immature development.

Obstructive apnea is when there is a brief pause of airflow in the pharynx where the muscles are too weak to help the infant breathe properly.

Mixed apnea is a combination of the two.

Treating Neonatal Apnea

To manage apnea in infants born before 34 weeks gestation, it is important for professionals in the neonatal intensive care unit to monitor breathing and development. Underlying causes will also have to be determined and close monitoring is imperative. Health professionals will check to see if there is a link to bradycardia and hypoxia.

Bradycardia is a heart rate that is too slow for normal functionality. Hypoxia is when there is an oxygen distribution deprivation. These two conditions are often linked to cases of apnea in infancy.

Management varies between infants and will depend on a series of factors. Medicines will be administered depending on the severity and cause of the issue.

Untreated apnea can cause unwanted effects to the overall wellbeing of the child. These effects can be a failure to thrive or decrease in intellect. Certain types of apnea can also result in death.

Having a wide group of trained health professionals can assist in the monitoring and betterment of neonates. Once proper diagnosis and treatment are implemented, the infant can be treated accordingly until the risks decline and their health improves.
