Diagnosis and discussion
DKA usually is diagnosed by a laboratory glucose that is greater than 11 mmol/L, a blood gas with a pH below 7.3, bicarbonate lower than 20 mmol/L and a positive result for ketones in the urine. In figure 1 it shows the patient’s blood glucose is 55.3 mol/L, the pH is …show more content…
This confirms that the patient is suffering from DKA and needs to be treated urgently according to the DKA protocol. The high CRP suggests an infection is present in the patient and this will need to be treated. This infection is probably the cause of the change in insulin requirements which brought on the DKA episode. Also an EP was ordered along with an urgent potassium and a venous blood gas to check the level of metabolic acidosis. The sodium is only slightly low so there is some hyponatremia present and definite severe metabolic acidosis due to the low pH and base excess. The lactate is very high which can happen when a diabetic patient takes metformin and it will need to be investigated to prevent lactic acidosis also occurring. An ECG can also be completed to check for any abnormalities related to the hypokalaemia. While the potassium seems normal from a second repeat sample sent after the haemolysed sample
