Seizures in Asphyxiated Term Newborns Based on Admission Thompson Score at the Women and Newborn Hospital, University Teaching Hospitals in Lusaka, Zambia.

Abstract

Purpose: The main purpose of the study was to investigate seizures in asphyxiated term neonates based on the admission Thompson score at the University of Zambia, Women and New-born Neonatal Intensive Care Unit. Methodology: A cross-sectional descriptive study design was used to conduct the study between (May 2022 to April 2023) in the Neonatal Intensive Care Unit (NICU) at the University Teaching Hospital for Women and Newborns in Lusaka Zambia. Stratified sampling was used to collect 217 files of neonates born at the tertiary facility as well as those referred from other centres with Apgar scores of ≤ 7 at one and five minutes of life. A structured questionnaire was used to collect data from medical records, the Thompson score (TS) was assessed on admission and details of neonatal seizures were analyzed using chi-square, fisher’s exact test and multivariable logistic regression. Findings: On admission, TS assessment was conducted on all 217 neonates of which 169 (77.9 %) neonates were classified with mild HIE,45 (20.9 %) moderate and 3(1.4 %) with severe HIE. Most neonates (77.4%) presented with seizures on admission. Results of the chi-square and fisher's exact tests showed that Thompson's score on admission was significantly associated with seizure occurrence (p=0.001). On multivariable binary logistic regression neonates with moderate HIE had over 10 times more odds of seizure occurrence compared to neonates with a mild HIE score (aOR=10.6, CI=2.32, 48.1, p=0.002). A unique contribution to theory, practice, and policy: The study concluded that seizures were present in all categories of HIE, the majority of who were classified with moderate HIE based on the Thompson score. Therefore, improving the quality of intrapartum care at the Women and Newborn Hospital can significantly reduce the occurrence of asphyxia and its complication.
