A number of intravenous medicines are solubilized in propylene glycol, which may accumulate in the plasma over time. Because calcium oxalate is a very low solubility product, significant hypocalcemia can result from precipitation of calcium by oxalic acid. In the ED he is alert and cooperative, oriented to person, place and time. Similarly, using a falling bicarbonate level as indirect evidence of ethylene glycol poisoning will not work if sufficient "blocking" levels of alcohol are present. Worse, the negative predictive value is poor, which means that one can have a significant ethylene glycol poisoning with a small or even absent osmolal gap. Critically ill patients may have elevated osmolal gaps. This can be a set of simple immunoassays for recreational drugs, which can be performed as a Point of Care or a laboratory-based test. Once the presence of ethanol has been excluded, this information can be used cautiously to calculate the approximate amount of ethylene glycol present by the observed gap as follows:.

  • clothing, further tests could be conducted to determine whether significant variation in venom reduction by biting snakes exists with the normal range of thickness.

    A Rapid Qualitative Test for Ethylene Glycol

    METHODS: Clinical manifestations and laboratory tests in the two patients were.
    Unfortunately, the presence of an osmolal gap is neither sensitive nor specific for EG. Although calcium and creatinine may be ordered for routine care, the presence of hypocalcemia and presence of an elevated creatinine direct the diagnosis toward ethylene glycol and away from methanol intoxication.

    In order to assess a possible EG exposure, CPCS recommends obtaining simultaneous measured and calculated osmolalities for which electrolytes, BUN and EtOH will be neededan ethylene glycol level, blood glucose, creatinine, calcium and arterial blood gases. Urine tox screen is negative for drugs of abuse.

    Glycolate and glyoxalate contribute further to the acidosis and further metabolism to oxalate which precipitates in tissues including the kidney.

    Facebook YouTube Twitter. In the absence of a stat EG level or a serum osmolality, the physician caring for the patient elects to follow the serum bicarbonate level as a possible marker of severity of ethylene glycol poisoning. Powered By Decision Support in Medicine.

    Because ethylene glycol is a large molecule relative to, say, ethanol or methanol, it produces significantly less effect on osmolality per equal weighted dose than do the smaller alcohols. Minor effects were attributed to 62 exposures.

    Because calcium oxalate is a very low solubility product, significant hypocalcemia can result from precipitation of calcium by oxalic acid.

    Acid base status should be monitored carefully in patients receiving ethanol. These readily available tests are rapid and inexpensive to perform.

    Glycolate is then metabolized into glyoxylate and finally oxalate. For calculation of the osmolal gap, a simultaneous measurement of serum sodium, glucose, and BUN are required. Rapid recognition and prompt treatment are crucial to prevent renal failure and other serious sequelae.

      A time frame of serum and urine within one to six hours post-exposure creates best results in most cases. Acid base status should be monitored carefully in patients receiving ethanol.
