nurse-with-a-smile: Intradermal: This route is usually used for tuberculin testing or checking for medication/allergy sensitivities It may be used for some cancer immunotherapy Use small amounts of solution [0.01-0.1 mL] in a tuberculin syringe with a fine-gauge needle [26 to 27] in lightly pigmented, thin skinned, hairless sites [inner surface of mid-forearm or scapular area of back] at a 10-15 degree angle. Subcutaneous: This route is appropriate for small doses of nonirritating, water-soluble medications and is commonly used for insulin and heparin. Use a 3/8- to 5/8-inch, 25- to 27-gauge needle, or an insulin syringe of 28- to 31- gauge. Inject no more than 1.5 mL solution. For an average size client, pinch up skin and inject at 45-90 degree angle. For an obese client, use a 90 degree angle. Sites are selected for adequate fat-pad size [abdomen, upper hips, lateral upper arms, thighs] Intramuscular: This route is appropriate for irritating medications, solutions in oils, and aqueous suspensions. Most common sites include ventrogluteal, dorsogluteal, deltoid, and vast us lateralis [pediatric] Use needle size 18 to 27 [usually 22- to 25-gauge], 1 to 1.5 inches long, and inject at a 90 degree angle. Volume injected is usually 1-3 mL. If > 3 mL is required, divide into two syringes and use two sites. -- source link
