Lab case 385

Posted on by

21-year-old girl with history of type I DM. Her BSL level at home was 37 mmol/L. So, she self-administered 10 units of Actrapid. She rechecked her BSL 1 hour later and it was 38 mmol/L so she decided to present to ED. On arrival to ED her VBG showed the following:

PH = 7.344

pCO2 = 34.8 mmol/L

pO2 = 47.2 mmol/L

HCO3 = 18.4 mmol/L

Na = 138 mmol/L

K = 3.6 mmol/L

Cl = 99 mmol/L

Hb = 142 g/L

Glucose = 20.7 mmol/L

Lactate = 9.5 mmol/L

Creatinine = 52 umol/L

Questions:

  1. Interpret these results
  2. How will you manage this patient
