Hi oowright
Please, what is the relationship between ml, unit and mcg as used in this forum?
Not just this forum but everywhere -- The U.S. uses the inch/pound/quart/pint/etc. system. Everywhere else uses the metric system. (meters/grams/liters) U.S. system is very confusing (1' = 12", 3'=1 yard, 1 lb = 16 oz, 4 qts = 1 gallon, etc), metric system is clearer. Everything is a multiple of 10. All scientists worldwide use the metric system.
a ml (milliliter) is 1/1000 of a liter (.001) and is a measurement of a liquid
a mg (milligram) is 1/1000 of a gram and is a measurement of a solid (powder, rock, etc.)
a mcg (microgram) is 1/1,000,000) of a gram and is a measurement of a solid
Injections are based on a standard insulin syringe which has graduations called units from 0 to 100 (for a 1 ml syringe) and 0 to 50 for a 0.5 ml syringe. Thus, 25 units on either syringe is equal to 1/4 of a ml. (0.25 ml)
Scripts for injections are typically given with using weight/milliliter. A typical starting script of 10, 30, 1 means
10 mcg/ml of PGE-1, 30 mg/ml of papaverine and 1 mg/ml of phenolamine. Note the PGE-1 is usually in mcg not mg. Some docs and/or pharmacies also list the concentration of chemicals per the size of the vial supplied (Empower does this.) Thus, a 5 ml vial will have numbers 5x larger that above.
So then, to confuse the unwary FrankTalk user even more, people on this board often list their scripts as their docs write them, and every doc has his own style. They reorder the chemicals, some specify the PGE-1 in mg, rather than mcg, etc.
If you really want an intelligent answer to a problem here, always list your script with the gms/ml #'s for each chemical as well as the number of units used for an injection. Without that info, and response is limited.
Hope I helped you, ............ Big
