subcutaneous injection... My 6 year old Italian Greyhound is very sick :-( We give him 1.5 ML - 2 ML every other night from an IV bag... sometimes every night.... treating chronic renal kidney failure.
Needle Angles: Standard medication doses for adults are to be rounded to the nearest tenth (0.1) of a milliliter. The standard 3-mL syringe is calibrated in tenths of a milliliter. The nurse should not administer more than 3 mL per intramuscular or subcutaneous injection site; when a volume greater than 3 mL is required, a 5-mL syringe, calibrated in fifths, may be used.
Comparison of the angles of insertion for intramuscular (IM), subcutaneous, and intradermal injections. An IM injection is given at a 72- to 90-degree angle. A subcutaneous injection is usually given at a 45-degree angle, but may be given at up to a 90-degree angle, if a short needle is used or if the person is heavy. The intradermal injection is given holding the syringe nearly parallel to the skin (10- to 15-degree angle).
