Increased osmolal gap in alcoholic ketoacidosis and lactic acidosis.
Derivation and validation of a formula to calculate the contribution of ethanol to the osmolal gap.
6) In such cases, the urine osmolal gap
, defined as urine osmolality - (2[Na+ + K+] + [urea] + [glucose]) should be used, since the gap mainly reflects the excretion of N[H.
After hemodialysis was performed, the patient's postdialysis serum showed an osmolal gap of 6 mOsm/kg and an EG concentration of 50 mg/dL (8.
The diagnosis of EG toxicity is made via a combination of the patient's history, the clinical picture, and a laboratory analysis showing an anion gap metabolic acidosis with an increased osmolal gap.
Patients with AKA will present with an increased anion gap in combination with an increased osmolal gap
and osmolality for healthy and ED patients in 1998 and 2007-2009.
As it happened, we were alerted to a potential problem by the unusually large negative osmolal gaps
in all 3 patients.
measurement of the serum or plasma osmolality and calculation of the osmolal gap
, have been studied as alternatives to direct assays of these alcohols (55,56).
Laboratory values on admission are given in Table 1 and include a metabolic acidosis with increased anion gap and an increased osmolal gap
The questions relate to topics like acid-base disturbances, sodium concentration disorders, the utility of urine anion and osmolal gaps
, the use of bicarbonate to treat metabolic acidosis, the use phosphorus binders to treat hyperphosphatemia, the interpretation of changes in plasma creatinine, the urine-to-plasma creatinine ratio, acute renal failure vs.
