Frequency of major congenital malformations in neonates born in three tertiary care hospitals of Pakistan.

Abstract

Objective: To assess the frequency of major congenital anomalies in newborns delivered in three different hospitals of Pakistan. Study Design: Cross Sectional study. Setting: Department of Pediatrics Hameed Latif Teaching Hospital, Lahore, Ittefaq Hospital Lahore and HITEC-IMS Taxilla. Period: Jan 2023 to November 2023. Methods: 205 neonates who met the inclusion criteria were included in the study from labour room of Hameed Latif Teaching Hospital Lahore, Ittefaq Hospital Lahore and HITEC-IMS Taxilla. Informed consent was obtained from parents. Demographic variables (name of mother, gender, birthweight and gestational age at birth) were recorded. Then neonates were admitted in NICU and evaluated for presence of congenital malformations including cardiovascular system defects, limbs anomalies, genitourinary system, central nervous system and chromosomal anomalies. All data was entered in specially designed performa. Results: We found that overall gestational age was greater than 32 weeks with mean age of 37.190±2.00 weeks. Mean birth weight was 2.938±0.31 Kg. Frequency and %age of patients according to gender was 60% males and 40% females. Major congenital malformation was seen in 2.9% patients. Among infants with major congenital malformations, cardiovascular system defects were seen in 33.3% infants, limb anomalies 16.7%, genitourinary system 16.7% and central nervous system defects were 33.3%. Parents of 67.7% of cases were cousins. It was observed that only 32.3% of the mothers had taken the recommended daily dose of folic acid in antenatal period. Conclusion: Central nervous system and cardiovascular system defects were the most prominent anomalies detected. Prenatal diagnosis may be helpful in decreasing mortality by offering early termination.
