When medication administration is subcutaneous tissue , substances get much faster blood circulation unless administer orally. In addition, subcutaneous injection produces far less damage to the intramuscular and low risk .
Absorbed by capillary circulation , drugs recommended to administer subcutaneously are aqueous solutions or suspensions of approximately 0.5 – 3 ml . Heparin and insulin , for example , be administered substances , particularly in this way . Drugs administered in this way with a needle are short and thin. The most common subcutaneous injection sites are exerioară the arms, the outer thighs, lower abdomen fat , upper thigh , upper back , upper buttocks . Subcutaneous injections are contraindicated in inflamed areas , edematiate that lesions .They can also be contraindicated for people with disorders of coagulation . When treatment is administered subcutaneously long time , such as insulin administration sites will be selected by rotation .Heparin is administered , preferably in the lower abdominal fat and insulin , in the upper part of the arms and belly .

 confirming patient identity
 patient explains the procedure to ensure its full cooperation and to reduce anxiety
 ensure privacy

 skin fold is issued to introduce no substance in the tissue under compression and do not irritate the nerve fibers
 aspirate to see if we are in a blood vessel
 If blood appears in the syringe and suction will throw technique will resume
 there are sucked in making heparin and insulin injections ( it is not necessary to insulin and heparin may produce hematoma)
 injected substance , lifting the needle gently but quickly , in a single movement, in the same angle as it was inserted
 cover the injection site with a gauze pad or fortified gentle massaging , circular to facilitate absorption of the drug ( will not be rubbing when adminstrează insulin or heparin)
 remove compress and check the place to detect any bleeding or bruising

Special considerations :
 for boilers instead of heparin is indicated in the lower abdomen, below the navel
 will always have to be alternate injection sites to prevent complications ( lipodystrophy , for example , the body’s natural immune response occurring in the case of repeated injection at the same site )
 after injection of heparin remains the syringe 10 seconds before removing . Avoid massaging the injection site .
 if there is bruising at the injection of heparin may apply ice for the first 5 minutes after injection and then do compression
