ABSTRACT
Background: Hyperbilirubinemia in newborn is quite common. Phototherapy (PT) is one of the most common noninvasive methods for the treatment of this hyperbilirubinemia. There are limited studies available on effect of PT on platelet count with contrasting results. So, this study was conducted to determine the effect of phototherapy on platelet counts of hyperbilirubinemic neonates in tertiary care hospital.Methods: This was a hospital based prospective study on 60 eligible neonates admitted in neonatal intensive care unit (NICU) for neonatal hyperbilirubinemia and phototherapy during January 2021 to June 2022. Platelet count was done before starting phototherapy, 24 hours after phototherapy and before discontinuing phototherapy. The results were analyzed statistically using Chi square test and t-test. P value <0.05 was considered as statistically significant.Results: In this study, total of 60 neonates were included of which 33 were males and 27 were females. The mean (±SD) platelet counts were 201764.92±18 before phototherapy and 156578.33±38 after phototherapy. There was a significant decline in the mean platelet count 24 hours after phototherapy and before stopping phototherapy. (p<0.05).Conclusions: In our study, the mean platelet count was decreased significantly after phototherapy. Hence, unnecessary use and prolongation of phototherapy should be avoided.
ABSTRACT
Background: Screening for congenital hypothyroidism (CH) is a routine practice in most developed countries of the world. This can be done by measuring cord blood thyroid stimulating hormone (CBTSH). Apart from foetal thyroid status and iodine nutrition status of the population, many perinatal factors may also affect CBTSH. The influence of these perinatal factors may affect the sensitivity of CBTSH as a screening tool for CH. The present study was carried out to study the influence of various perinatal factors on CBTSH level.Methods: It was a cross sectional study conducted in tertiary care centre in North Maharashtra. 793 new-borns were included in study. Effects of perinatal factors like maternal age, parity, gender of the baby, birth weight, mode of delivery, gestational age, birth asphyxia on CBTSH was analysed with appropriate scientific method.Results: The mean TSH level in the study group was 7.56±3.9 mIU/l. Among the associated factors vaginal delivery, low gestational age, low birth weight and birth asphyxia were significantly associated with elevated CBTSH values. Hence, any rise in cord blood TSH should be seen in the light of these factors.Conclusions: Among all the associated factors, primi-parity, vaginal delivery, low gestational age, low birth weight and birth asphyxia were significantly associated with elevated CBTSH values. However, no association was observed between CBTSH values and gender of the baby and maternal age.
