needlestick injuries, accidental skin punctures resulting from contact with hypodermic syringe needles, IV cannula stylets, needles used to “piggyback” IV infusions, and needles used for drawing blood or administering parenteral injections. The contact may occur accidentally during efforts to inject a patient or as a result of carelessly touching discarded medical waste. Such injuries can be dangerous, particularly if the needle has been used in treatment of a patient with a severe blood-borne infection, such as human immunodeficiency virus. To prevent injuries, used needles are not capped or broken and are disposed of in a rigid puncture-resistant container located near the site of use.
