Neonatal convulsions--a 10 year review.
Archives of Disease in Childhood
|December 1, 1983
Summary
Neonatal convulsions, often linked to cerebral hypoxia, saw increased incidence over a decade. While overall mortality decreased, it remained high for hypoxia-related seizures in newborns.
Area of Science:
- Neonatology
- Pediatric Neurology
Background:
- Neonatal convulsions represent a significant clinical challenge.
- Understanding their incidence and causes is crucial for improving outcomes.
Purpose of the Study:
- To review the incidence and aetiologies of neonatal convulsions over a 10-year period.
- To compare trends across different time intervals within the decade.
Main Methods:
- Retrospective review of hospital records for neonatal convulsions.
- Analysis of live birth data across three distinct periods: 1971-4, 1975-7, and 1978-80.
Main Results:
- Overall incidence of neonatal convulsions increased from 2.6 to 8.6 per 1000 live births.
- Cerebral hypoxia and 'fifth day fits' were the most common aetiologies.
- Improved investigations reduced the proportion of unexplained cases to 11%.
Conclusions:
- Despite an overall reduction in mortality, cerebral hypoxia remains a major cause of neonatal convulsions with high mortality rates (>50%).
- Continued research into the causes and management of neonatal seizures is warranted.
