How would you treat her?


One thought on “Lab Case 133

  1. She has a mixed acidosis (HAGMA and NAGMA). Winter’s formula would suggest it is not adequately compensated (there is a relative respiratory acidosis)…

    So you need to go looking for the cause of a three problems

    Ketones are up, so likely dehydrated – so some fluids, urine output monitor, then serial gases. Avoid saline, maybe hartmann’s or plasmalyte as perhaps the 3rd space loss, fistula, diarrhoea or a RTA has put up the chloride relative to the low bicarbonate.

    Screen for sepsis

    GIve some thiamine

    If she has chronic pancreatitis could consider screening with CT for complications such as pseudocysts.

    Call surgeons

    Admit to HDU
