From the Guidelines

NAI stands for Neonatal Abstinence Syndrome in the context of pediatric seizures, which refers to a condition where newborns experience withdrawal symptoms after being exposed to opioids or other substances in the womb. When evaluating a child with seizures, healthcare providers must consider NAS as a potential cause, particularly if the seizure presentation is accompanied by other symptoms such as tremors, irritability, or feeding difficulties. According to the study by the American Academy of Pediatrics 1, withdrawal-associated seizures seem to be primarily myoclonic, respond to opiates, and carry no increased long-term risk of poor outcome. Some key points to consider when evaluating NAS include:

  • The use of opioids, such as morphine or methadone, as the primary treatment for NAS 1
  • The potential benefits of using clonidine as an adjunctive treatment to reduce withdrawal symptoms 1
  • The importance of monitoring for signs of NAS, such as seizures, tremors, and irritability, in infants born to mothers who have used opioids during pregnancy 1 It is essential to note that NAS is a condition that requires prompt medical attention, and healthcare providers should be aware of the signs and symptoms to provide appropriate treatment and support to affected infants. In terms of seizures, the study suggests that they are a common symptom of NAS, and that they can be effectively managed with opioid treatment 1. Overall, healthcare providers should prioritize the diagnosis and treatment of NAS in infants with seizures, and consider the use of opioids and adjunctive treatments like clonidine to manage withdrawal symptoms.

From the Research

Definition of NAI

  • Non-Accidental Injury (NAI) refers to deliberate inflicted trauma to children, which has been occurring for centuries but has only recently been described as a distinct clinical entity 2.
  • NAI encompasses a broad spectrum of manifestations, ranging from trivial superficial injuries to potentially fatal severe brain trauma, including Non-Accidental Head Injury (NAHI) 2.

Relation to Seizures in Paeds

  • While NAI is a significant concern in pediatric care, the provided studies do not directly link NAI to seizures in children 2, 3, 4, 5, 6.
  • However, it is essential to consider the possibility of NAI in cases of unexplained head trauma or seizures in children, as it may be a contributing factor to the development of seizures or epilepsy 2.

Key Considerations

  • Imaging plays a crucial role in raising the suspicion of NAI and assessing the probability of the condition given the objective imaging features available 2.
  • In cases of suspected seizures or NAI, it is critical to initiate a systematic approach to precise etiologic diagnosis and treatment, including EEG monitoring and urgent evaluation of the seizure etiology 3.
