title: Status of liver enzymes in babies with perinatal asphyxia.
abstract: Because of hypoxemia, different organ systems of the body are affected in perinatal asphyxia. In this study, the functional status of liver of the asphyxiated babies was assessed through estimation of liver enzymes to see any correlation existing between enzyme changes and severity of perinatal asphyxia. A total of 70 full-term asphyxiated newborns (study group) were studied during January'2008 to December'2008 in the department of Paediatrics, Mymensingh Medical College Hospital. After enrollment these babies were grouped according to Sarnat & Sarnat stages of Hypoxic-ischemic encephalopathy (HIE) as stage I, II & III. Babies who are small for gestational age, having severe jaundice, sepsis or congenital anomalies of the hepatobiliary system were excluded from the study. Another 50 healthy newborns were also studied as control group. Venous blood was analyzed between 2nd and 5th day of life to estimate serum AST, ALT & alkaline phosphatase (ALP). Unpaired student's 't' test and Spearman's rank correlation was used for data analysis and P value of <0.05 were considered significant. Mean AST, ALT and ALP of the asphyxiated babies were 76.27±37.44, 82.16±48.08 & 369.59±123.05 U/L and that of normal babies were 23.46±8.45, 26.54±7.76 & 208.20±46.95 U/L respectively and these rise were statistically significant (p<0.001). The levels of transaminases and ALP were positively correlated with the severity of asphyxia and these correlations were also statistically significant (p<0.001). So, this study concludes that AST, ALT & ALP significantly elevated in perinatal asphyxia and this elevation was proportional to the severity of hypoxia.
