Acute kidney injury in asphyxiated neonates admitted to a tertiary neonatal unit in Sudan.

Acute kidney injury (AKI) is a recognized complication of birth asphyxia. Early recognition of AKI is important in asphyxiated neonates as it helps in early intervention and appropriate management. The aim of this study was to determine the pattern of AKI in asphyxiated neonates and its relation to the grade of Hypoxic Ischemic Encephalopathy (HIE). This was a prospective hospital based study, conducted in the neonatal intensive care unit (NICU) at Gafaar Ibn Auf Children's Specialized Hospital during the period between January 2013 and December 2013. A total of 85 full term asphyxiated neonates who were admitted in NICU and diagnosed as HIE were enrolled in this study. with 50 (58.8%) less than 7 days of age, 31(36.5%) between (8-15) days and 4(4.7%) between (16-28) days. Males were found to be more affected than females (58.9% and 41.1%) respectively. Spontaneous vaginal delivery was the mode of delivery in 48(56.4%), assisted vaginal delivery in 14(16.5%), emergency caesarian in 19(22.4%) and elective caesarian section in. Percentage of AKI in those babies was 54.1%(46). With 30(65%) from those had non-oliguric type. Ten babies (21.7%) had serum creatinine between (1.5 - 2mg/dl), 29 (63.04%) between (2 - 3mg/dl) and 7(15.22%) between (3-4mg/ dl). This means that the majority of patients presented in injury stage. Hyperkalemia was found in (37.6%), hyponatremia in (27.1%) and hypocalceamia in (25.8%). Most of the babies with AKI had stage (ii) HIE. All babies were treated conservatively and 4(8.6%) died. In conclusion AKI was observed to be a common complication in asphyxiated neonates.
