Abstract

Hyperlactatemia is a documented complication of diabetic ketoacidosis (DKA). Lactate responses during DKA treatment have not been studied and were the focus of this investigation. Blood gas and electrolyte data from 25 DKA admissions to ICU were sequenced over 24 h from the first Emergency Department sample. Hyperlactatemia (> 2 mmol/L) was present in 22 of 25 DKA presentations [mean concentration = 3.2 mmol/L]. In 18 time-series (72%), all concentrations normalized in ≤ 2.6 h (aggregate decay t1/2 = 2.29 h). In the remaining 7 (28%), hyperlactatemia persisted > 12 h. These were females (P = 0.04) with relative anemia (hemoglobin concentrations 131 v 155 g/L; P = 0.004) and lower nadir glucose concentrations (5.2 v 8.0 mmol/L, P = 0.003). Their aggregate glucose decay curve commenced higher (42 mmol/L v 29 mmol/L), descending towards a lower asymptote (8 mmol/L v 11 mmol/L). Tonicity decay showed similar disparities. There was equivalent resolution of metabolic acidosis and similar lengths of stay in both groups. Hyperlactatemia is common in DKA. Resolution is often rapid, but high lactates can persist. Females with high glucose concentrations corrected aggressively are more at risk. Limiting initial hyperglycemia correction to...Continue Reading

Anemia

Anemia develops when your blood lacks enough healthy red blood cells. Anemia of inflammation (AI, also called anemia of chronic disease) is a common, typically normocytic, normochromic anemia that is caused by an underlying inflammatory disease. Here is the latest research on anemia.
