Neonatal Seizures, NICUAbstract
Introduction: Neonatal seizure is defined as paroxysmal electrical discharge from the brain. The immature brain seems more prone to seizures. The incidence was found to increase with decreasing gestation and birth weight- preterm neonates (20.8 vs. 8.4 per 1000 live-births) while very low birth weight neonates had more than 4-fold higher incidence (36.1 per 1000 live-births).
Objective: The study was conducted to estimate the incidence, etiological factor, time of onset, clinical types, and biochemical abnormalities among the different types of neonatal seizures.
Methods: This is a hospital based prospective observational study conducted in NICU, Department of Pediatrics, SMIMER during the period of January 2020 to March 2021.
Results: Total patients with neonatal seizures were 90 in our study. Inci-dence of neonatal seizures in our study was 1.1%. Incidence was higher in preterm neonates (4.8%) and more in males (56.67%). Incidence of neonatal seizures was higher in LBW babies (4.3%) and more common in SGA babies (51.11%). Incidence among vaginal delivered babies was 0.9%, LSCS was 1.7% and forceps was 1.1%. Birth asphyxia (41.1%) was the most common cause of all neonatal seizures followed by hypoglycemia (17.8%), neonatal meningitis/septicemia (14.5%), hypocalcemia (12.2%), ICH (7.8%). Subtle seizures (44.4%) were the commonest type of seizure followed by tonic (38.9%), focal clonic (11.1%), multifocal clonic (5.6%). 33.3% of neonatal seizures occurred in < 24hrs & 40% in 24-72 hrs. The most common biochemical abnormality was hypoglycemia (17.8%) followed by hypocalcemia (12.2%).
Conclusion: Incidence of neonatal seizures was 11.1/1000 live births (1.1%) & more common in preterm, LBW & LSCS deliveries. Birth asphyxia was the most common cause and subtle seizures were the most common type of seizure. Subtle seizures were more common in 24-72 hours of life. Most common biochemical abnormality was hypoglycemia followed by hypocalcemia.
