“…[4][5][6]8,[11][12][13] The majority of Nigerian studies on the prevalence rate and pattern of hypoglycaemia among children admitted into the emergency room were at cut-off values of blood glucose concentration <2.2 mmol/L or plasma glucose concentration <2.5 mmol/L, which were acceptable at the time as the definition for hypoglycaemia but at which point complications, especially neurological sequelae, may have set in. [5,6,[10][11][12] Concerns to avoid these complications arising from hypoglycaemia, especially neurological sequelae, have caused the bar to be raised in the definition of hypoglycaemia, to blood glucose <3.1 mmol/L (55 mg/dL), [2] and plasma glucose <3.4 -3.5 mmol/L (60.5 -63.3 mg/dL). [2] The present study sought to determine the prevalence of hypoglycaemia among children admitted into the children's emergency room of a typical Nigerian teaching hospital, at a plasma glucose cut-off value <3.4 mmol/L, identify some of its associated Background.…”
