Abstract

Introduction: Perinatal asphyxia is defined as the failure to initiate and sustain breathing at birth. Aim: compare functional echocardiographic parameters of perinatal asphyxiated term neonates with non asphyxiated term neonates. Methodology: This observational study, conducted at the Division of Pediatric Cardiology in M.D.M Hospital under the Department of Pediatrics, Dr. S.N. Medical College, Jodhpur, focused on perinatal asphyxia and hypoxic ischemic encephalopathy (HIE). Perinatal asphyxia severity was classified as moderate or severe based on breathing patterns and APGAR scores at 1 minute after birth. HIE diagnosis relied on physical examination, utilizing the modified Sarnat & Sarnat staging system to determine severity. Result: our observational study compared functional echocardiographic parameters between perinatal asphyxiated term neonates and non-asphyxiated term neonates. The findings revealed significant differences in certain parameters between the two groups: La and Ao did not differ significantly between the study and control groups.The ratio of La to Ao was significantly higher in the study group. LVES was significantly larger in the study group. EF and FS were significantly lower in the study group, indicating impaired cardiac function. Other parameters such as LVMPI, MAPSE and mitral E/A and E/e' ratios did not show significant differences between the two groups. However, the diastolic diameter of the tricuspid annulus was significantly larger in the study group compared to the control group. Conclusion: The perinatal asphyxia may impact specific echocardiographic parameters indicative of cardiac dysfunction, particularly in terms of left ventricular systolic function.Early recognition and management of cardiac involvement may improve outcomes in this vulnerable population.
