Incidence of congenital anomalies in newborn in tertiary care hospital

Abstract

Background: Just about three decades ago (1976) congenital malformations comprised 8% of perinatal deaths, from available data and ranked fifth as a cause of perinatal mortality. But the trend is rapidly changing over the years. perinatal death was due to congenital malformation, is the second commonest cause. This changing trend over years warns us that with the control of nutritional and infectious diseases, congenital malformations will come to the forefront as it is in India. To find out the incidence of congenital anomalies in stillbirth. And the probable etiology of congenital anomalies.Methods: The study was conducted at Government Mohan Kumaramangalam Medical College Hospital, Salem in the year 2017 August- September 2018. Totally 5000 babies born of consecutive deliveries were taken for the study, over the period of one year. All mothers were interrogated within 48 Hours of delivery as per the proforma prepared, which contains the following particulars like, maternal and paternal age, consanguinity, detailed antenatal history with reference to exposure to teratogens, especially during 1st Trimester.Results: Of the five thousand consecutive deliveries 48 deliveries were multiple delivers and a number of stillbirths were 108. The incidence of congenital anomalies was 30.4 per 1000 live birth (152 cases). Major malformations were present in 20.8 per 1000 (104 cases) while minor malformations were 9.6 per 1000 (48 cases).Conclusions: Incidence of malformation were higher in preterm babies 6.31%. Incidence of malformations were higher in male babies, especially genitourinary system anomalies. Antenatal events in the 1st trimester like fever, drug intake could be implicated in the etiology of malformations especially neural tube defects in our study.
