- Examples include drawing blood samples, aspirating fluid from joints, or removing excess fluid from the body.
- Diagnostic Procedures: While lancets are specifically designed for obtaining blood samples, some procedures might involve the use of needles.
Needles in Medical Practices
- Precise Delivery: Needles allow healthcare professionals to deliver medication to specific areas of the body, ensuring targeted action and efficacy.
- Rapid Absorption: Intramuscular and subcutaneous injections made with needles provide faster absorption compared to oral medications.
- Sterility: Medical-grade needles are designed to be sterile and disposable, minimizing the risk of infection.
In conclusion, the primary role of needles, as per the provided reference, is for injecting medications under the skin, while related instruments like syringes and lancets have their own unique purposes in the medical field.
