Michigan HIE Attorney Explains A New Study: Babies with Mild Hypoxic Ischemic Encephalopathy May Not Receive Hypothermia Treatment

Neonates that don’t receive enough oxygen around the time of labor and delivery risk developing a dangerous brain injury called hypoxic ischemic encephalopathy (HIE). HIE is caused by decreased blood flow and oxygen in the brain. HIE can cause permanent brain damage, leaving a child with lifelong conditions, such as seizures, cerebral palsy (CP), developmental disabilities and motor disorders.

A new study found that even mild hypoxic ischemic encephalopathy can cause long-term problems in a child, such as intellectual disabilities, developmental delays, learning disorders, behavioral difficulties, speech delays, autism, attention deficit disorder and dyspraxia. This research is important because there is only one treatment for HIE, and if a child is diagnosed with a mild form of HIE, she will not qualify for the critical treatment. The treatment for HIE is called hypothermia (brain cooling) treatment and it must be given within 6 hours of the time the baby was deprived of oxygen. This usually means the treatment must be given within 6 hours of delivery. Hypothermia treatment for HIE has been shown to halt almost every injurious process that starts to occur when the brain experiences an oxygen-depriving insult. The treatment can significantly decrease the likelihood that HIE will cause permanent brain damage; research shows that this can prevent a child from developing cerebral palsy or it may reduce the severity of the CP.

Michigan HIE Attorney Discusses Birth Asphyxia, the Causes of HIE, and Medical Malpractice

Hypoxic ischemic encephalopathy (HIE) is the most common type of birth injury. It is often caused by oxygen deprivation (birth asphyxia) that occurs during or near the time of birth. During labor and delivery, problems with the umbilical cord, placenta or uterus can cause birth asphyxia. Listed below are conditions that can occur during or near the time of birth that can cause birth asphyxia and hypoxic ischemic encephalopathy (HIE).

Umbilical cord problems, such as a nuchal cord (cord wrapped around baby’s neck), umbilical cord prolapse, short umbilical cord and cord in a true knot
Ruptured uterus
Preeclampsia / eclampsia
Placental abruption
Placenta previa
Anesthesia mistakes, which can cause blood pressure problems in the mother, including a hypotensive crisis. This can greatly decreases the supply of oxygen-rich blood going to the baby, causing birth asphyxia.
Oligohydramnios (low amniotic fluid)
Premature rupture of the membranes (PROM) / premature birth
Prolonged and arrested labor
Intracranial hemorrhages (brain bleeds), which can be caused by a traumatic delivery. Forceps and vacuum extractors can cause brain bleeds. Sometimes intense contractions (hyperstimulation) caused by labor induction drugs (Pitocin and Cytotec) can cause head trauma. Mismanagement of cephalopelvic disproportion (CPD), abnormal presentations (face or breech presentation), and shoulder dystocia also put the baby at risk of experiencing birth trauma and birth asphyxia.
Hyperstimulation caused by Pitocin and Cytotec can also cause oxygen deprivation that gets progressively worse.
Fetal stroke
Postmaturity syndrome
Placental insufficiency and intrauterine growth restriction (IUGR)
Fetal stroke
Postmaturity syndrome
An infection that travels from the mother to the baby at birth, such as chorioamnionitis, Group B Strep, urinary tract infections (UTI) and bacterial vaginosis (BV), which can cause sepsis and/or meningitis
Failure to quickly deliver a baby when fetal distress is evident on the fetal heart rate monitor (delayed emergency C-section)
Mismanaged breathing problems after birth, such as failing to properly intubate and place baby on a breathing machine (ventilator); untreated apnea or respiratory distress; improper settings on the ventilator, which can cause overventilation injuries such as prolonged hypocarbia.

These conditions can cause hypoxic ischemic encephalopathy (HIE), permanent brain damage and lifelong problems such as cerebral palsy if they are not properly managed. Proper management almost always entails quickly delivering the baby before the oxygen deprivation starts to cause brain injury. The baby is supposed to be continuously monitored with a fetal heart monitor during labor and delivery. If the baby starts to become deprived of oxygen, the heart monitor will show nonreassuring heart tracings. Once these occur, it is the job of the medical team to try and alleviate the fetal distress. The team must also make preparations for a quick emergency C-section, in most cases. Babies experiencing oxygen deprivation must be delivered within 18 minutes, in most cases. In severe cases of birth asphyxia, such as a complete placental abruption or umbilical cord compression, the baby must be delivered a lot sooner, usually within a matter of minutes. A delayed delivery can cause hypoxic ischemic encephalopathy in the baby.

Michigan HIE Attorney Explains the Long-Term Effects of Hypoxic Ischemic Encephalopathy

HIE typically occurs in term babies, although premature infants can also develop HIE. When premature babies experience birth asphyxia, however, they often develop periventricular leukomalacia (PVL). HIE usually involves damage to the basal ganglia, cerebral cortex or watershed regions of the brain, but it sometimes does include periventricular leukomalacia (PVL).

Listed below are some lifelong conditions that can be caused by HIE and PVL:

Seizure disorders
Cerebral palsy (CP)
Intellectual disabilities
Developmental delays
Learning Disabilities
Motor disorders
Microcephaly
Hydrocephalus
Behavioral Difficulties
Speech Delays
Autism
Attention Deficit Disorder
Dyspraxia

Michigan HIE Attorney Discusses Neonatal Requirements for Hypothermia Treatment

If there is any possibility that a baby suffered a lack of oxygen in the brain, it is crucial for the medical team to closely monitor the baby for signs of hypoxic ischemic encephalopathy (HIE). The reason this is crucial is because hypothermia treatment is not given unless a diagnosis of HIE has been made. If a diagnosis is not promptly made, a baby may not receive the treatment, which means her brain injury may be much more severe than it would have been. The more severe the HIE, the sooner the hypothermia treatment must be started. Indeed, failure to promptly diagnose HIE is negligence.

Signs and symptoms of HIE may include the following:

The baby needed resuscitation at birth or at any time during the neonatal period
Low APGAR scores for longer than 5 minutes. An APGAR score assesses the overall health of a newborn over the first few minutes of life. It assigns scores to factors such as the baby’s skin color / complexion, pulse rate, reflexes, muscle tone, and breathing.
Seizures within the first 24 – 48 hours of delivery are an indication of HIE caused by an event during birth, and seizures while in the NICU or shortly after discharge from the NICU are an indication of an oxygen depriving insult that occurred after birth
Difficulty feeding, including inability to latch, suck or swallow
An acidic umbilical cord blood sample (Low pH)
Abnormal limpness
Multiple organ problems (e.g., involvement of the lungs, liver, heart, intestines)
No brain stem reflexes (e.g., breathing problems and an abnormal response to light, and only blood pressure and heart function reflexes are functioning)
Hypotonia (low muscle tone)

In determining whether a baby is eligible for hypothermia treatment, many hospitals use the criteria that the research trials used when studying HIE and brain cooling. The eligibility requirements for hypothermia treatment in many hospitals are:

Gestational age greater than 36 weeks
pH is less than 7 or base deficit is 16 or greater in umbilical cord arterial blood
If pH is 7.01 – 7.15, base deficit is 10 – 15.9, or a blood gas sample is not available, the additional criteria are required:
An sudden event during labor such as non-reassuring fetal heart tones (late or variable decelerations) umbilical cord prolapse or rupture, uterine rupture, maternal trauma, hemorrhage or cardio-respiratory arrest AND either a 10 minute Apgar score of 5 or less or assisted ventilation (baby is on a breathing machine or is being bagged) at birth that lasts 10 minutes or more
Evidence of seizures or neonatal encephalopathy (global brain injury) by a standard neurological exam

Some hospitals use criteria such as the following from the American Academy of Pediatrics in Virginia:

A. Infants >35 weeks gestation with ONE of the following:

Apgar score of < 5 at 10 minutes after birth
Continued need for resuscitation, including endotracheal or mask ventilation, at 10 minutes after birth
Acidosis defined as either umbilical cord pH or any arterial pH within 60 minutes of birth less than 7.00
Base Deficit > 16 mmol/L in umbilical cord blood sample or any blood sample within 60 minutes of birth (arterial or venous blood)

If the infant meets criteria A then assess for neurological abnormality:

B. Moderate to severe encephalopathy (Sarnat 2 or 3) consisting of an altered state of consciousness (as shown by lethargy, stupor, or coma) and at least one or more of the following:

Hypotonia
Abnormal reflexes including oculomotor or pupillary abnormalities
Absent or weak suck

Physicians at different hospitals may use varying methods for diagnosis of HIE. The key is for them to recognize signs of HIE, quickly diagnose the condition, and then begin hypothermia treatment. If the baby meets the criteria for hypothermia treatment listed above, the therapy should be started right away. Of course, if a diagnosis is made without all the criteria being met, hypothermia treatment should still be given, as long as the baby was born at or later than 36 weeks (greater than 35 weeks at some hospitals), the oxygen-depriving insult occurred within the 6 hour time frame, and there are no contraindications to the treatment. Hypothermia treatment is very easy to give and as of yet, researchers have not seen harmful effects of the therapy when it is properly implemented.
