WebMain component of rubbing alcohol Hallmark is osmolar gap, ketosis, that is without acidosis Metabolized to acetone, not to an acid Takes 30-60 min for acetone to appear in blood; 3 hr to appear in urine Lethal Dose: 4-8 g/kg or 250 mL in average adult (calculated using volume of pure isopropyl alcohol) WebA good example of how assumptions can be flawed concerns calculating the serum osmolality in the setting of alcohol poisoning where the true osmolality may be considerably higher than the estimated osmolality (using the formula: osmolality = [2 x Na +] + [BUN/ 2.8] + [ glucose / 18]).
