Newborn Breathing Problems (Birth Asphyxia) Neonatal

A major concern for many parents as the mother approaches full term  is the complications that may arise after delivery,  particularly breathing problems that may affect the newborn. At birth, the focus of the attending physician is to assure healthy and spontaneous breathing of the newborn as any impediment may result in damage to the brain tissue or even death.

However in certain cases, problems with adequate ventilation may arise, especially in high risk pregnancies.

What is Asphyxia Neonatorum?

Asphyxia is the lack of oxygen (hypoxia) or increase in carbon dioxide (hypercapnia) within the body due to problems with breathing.

Asphyxia neonatorum (sometimes referred to as birth asphyxia) is the hypoxia and/or hypercapnia that occurs in newborns. This may be categorized into perinatal asphyxia or neonatal asphyxia.

The chances of asphyxia neonatorum is significantly higher in high risk pregnancies, premature births, multiple births (twins, triplets or more), severe maternal bleeding or toxemia.

Perinatal Asphyxia

Perinatal asphyxia or fetal asphyxia is the asphyxia that results in the baby before or during labor. A rapid delivery is essential to secure the airways and ensure spontaneous breathing is possible.  Perinatal asphyxia may occur as a result of :

  • Umbilical cord compression
  • Abruptio placentae which is the premature detachment of the placenta from the wall of the uterus thereby cutting off vital oxygen rich blood from the mother to the baby.
  • Uterine tetany which is the continuous or prolonged uterine contractions that may occur as a result of complications in labor or certain drugs like oxytocin.
  • Maternal hypotension (low blood pressure) which hampers the delivery of sufficient oxygen to the fetus.
  • Uteroplacental insufficiency which prevents adequate gas exchange between the fetus and mother due to problems.
  • Fetal exsanguination which is the loss of blood from the fetus.

Neonatal Asphyxia

Neonatal asphyxia (newborn asphyxiation) is the asphyxia that results after the baby is delivered. Asphyxia neonatorum may occur as a result of :

  • Perinatal asphyxiation
  • Drugs – anesthetic or analgesics administered to the mother or the use of narcotics (‘crack mothers’)
  • Malformation of the lungs or breathing muscles.
  • Airway obstruction due to meconium, blood or fluids.

Clinical Evaluation of Asphyxia Neonatorum

Typically, the Apgar score system is used to evaluate the condition of the newborn, taking note of color, heart rate, respiration, reflex responses and muscle tone of the baby. These five physical signs are graded as 0, 1 or 2 and a total score of less than 5 is an indication of possible neurological damage and the need for an emergency response to ensure that the newborn survives.

Apgar Score

Apgar Score

The Apgar score is recorded immediately after birth and another recording is taken approximately 5 minutes after birth.


  • Newborn is blue or pale = 0
  • Body is pink but extremities are blue = 1
  • Body and extremities are pink = 2

* Color indicates either adequate or inadequate oxygenation of the blood. Pale or blue extremities at birth should not be an immediate concern if the body is pink and other factors do not indicate any depression.

Heart Rate

  • Absent = 0
  • Heart rate less than 100 beats per minute = 1
  • Heart rate greater than 100 beats per minute = 2

* Infant heart rates are significantly higher than adult heart rates and a rate of 100 beats per minute or greater is considered normal.

Respiration (Breathing)

  • Absent = 0
  • Slow or irregular breathing = 1
  • Good breathing = 2

* A crying baby is usually an indication of good breathing.

Reflex Response

This is assessed by the reflex response to stimulation, often from the insertion of a nasal catheter, usually upon suctioning although stimulation of the sole of the foot may also be considered.

  • No reflex response = 0
  • Grimace or noticeable facial movement upon stimulation = 1
  • Baby sneezes, coughs or pulls away upon stimulation = 2

Muscle Tone and Activity

  • Extremities are limp with little or no movement = 0
  • Some movement and flexion of the extremities = 1
  • Baby’s limbs are active and movement is spontaneous = 2

* Flexion refers to the bending of the limb at the knee or elbow or raising of the arms or leg at the shoulder or hip joint respectively.

A score of less than 5 indicates severe depression and the need for emergency medical attention. The maximum score of 10 is not often present even in healthy newborns and parents should not be concerned if their baby scores a healthy 8 or 9 on the Apgar score. Premature babies often have a lower apgar score and usually require ventilation at delivery.

In cases where the newborn’s Apgar score is recorded at less than 5, resuscitation is usually required.

Treatment of Neonatal Asphyxiation

The immediate priority of the attending physician is to secure integrity of the airway by clearing any secretions, fluid or blood. This is often done by suctioning with a soft catheter. In newborns who are well oxygenated but slightly limp due to the use of analgesics or anesthetics, the attending physician may gently slap the feet of the baby before commencing with suctioning.

After clearing the airway, ventilation with oxygen is usually necessary in asphyxia neonatorum. The attending physician may commence resuscitation with a neonatal bag mask with positive pressure ventilation. Efforts to stimulate the circulation may follow if positive pressure ventilation does not assist with suitable oxygenation noted by a pink color of the extremities. The newborn’s body temperature must be maintained during ventilation and efforts to stimulate circulation and this is usually done through heaters rather than just blankets.

Once the newborn baby is stabilized, he or she will usually be placed into an incubator to ensure positive pressure ventilation as well as suitable temperature regulation. This is often conducted in a neonatal ICU (intensive care unit)  where close observation by trained staff will ensure that there are no other episodes of hypoxia.

    my aby is 12 year old with birth asphyxia out of ventillator after 10 days , feed by pipe please advice me about her future and present

  • srk

    My baby is 17 days old with birth asphyxia. out of ventilator after 8 days. now he is good and discharged from hospital. will there be any future complications. what to do? how quickly it has to be treated.

      Hi SRK

      There are possible complications relating to mental development, neurological disorders and so on which will be difficult to assess at this early stage. There is also some evidence to suggest that there may be an increased chances of SIDS (‘cot death’). I think this is an issue you should discuss directly with your pediatrician. Parents tend to panic when reading articles online or in magazines as they are unable to decipher the relevant information. Your pediatrician will guide you through it. While there are these possibilities, it is also important to remember that many babies in this situation will grow up to be healthy children. It just depends on the individual case and the attending doctor/gynecologist will be better able to advise your pediatrician who can then direct you accordingly.


    My sister son was born on 26.07.2010 as soon he was born he was having breathing problem.i.e 100 plvs breathing rate…and doctor shifted him in nicu…

  • juvi

    my baby is 13 months old and i born him with moderate asphyxia and until now he cant afford to sit with his own and walk?is this a side effect?

    • Dr. Chris

      Hi Juvi

      It really depends on whether there was any brain damage at birth or not. He may just be a late developer in terms of walking but yes, at this point he should be sitting up on his own. There could be other musculoskeletal or neuromuscular problems that may also be responsible. You should take him to a pediatrician as there is no way of saying for sure just from what you mention.


    How long does the neck of the baby born with severe birth asphyxia take to get strong? He’s three months old now.

    • Dr. Chris

      Hi GMoloto

      A lot depends on the severity of the infarct (tissue death), whether is was bilateral and so on. Weaness usually starts to improve by 3 months. However, it varies on a case by case basis. The pediatrician and neurologist attending to your child will be better able to inform you.
