Safe use of medical syringes includes three main stages

• Before Injection: Check sterile packaging, expiration date, handwashing, and proper syringe size
• During Injection: Use a new needle, correct injection angle, air bubble control, and smooth plunger movement
• After Injection: Cover injection site, dispose syringe in sharps box, avoid bending needle, record injection
• Waste management and healthcare staff safety: using Sharps Containers, full staff training, prevention of needle‑stick injuries, and adherence to biohazard waste protocols.

Before Injection

• Expiration date check: Always verify the expiration date printed on the syringe packaging.
• Ensuring sterile packaging: The packaging must not be opened or damaged.
• Handwashing and wearing gloves: This helps prevent contamination.
• Choosing the appropriate syringe size: The size must match the type of medication and injection site.
• Medication preparation: The medication must be prepared under sterile conditions and protected from environmental contamination.

During Injection

• No touching the needle: The needle must not come into contact with the hand or any non‑sterile surface.
• Correct injection angle: Depending on the medication, the injection may be subcutaneous (Subcutaneous), intramuscular (Intramuscular), or intravenous (Intravenous).
• Smooth plunger movement: The injection must be performed with even pressure so the patient feels less pain.
• No reuse: Each syringe must be used only once.
• Air bubble control: Air bubbles must be removed from the syringe before injection to reduce the risk of embolism.

After Injection:

• Covering the injection site: With sterile cotton or bandage to prevent bleeding and infection.
• Not bending or breaking the needle: This increases the risk of injury and contamination.
• Immediate syringe disposal: The syringe must be placed immediately after use into the designated container (Sharps Container).
• Injection documentation: The medication type, dose, and injection time must be recorded in the patient’s file.

مدیریت پسماند پزشکی

• Use of standard safety box: Puncture‑resistant containers for collecting syringes.
• Replacing the safety box at the right time: It must be replaced when three‑quarters full.
• No disposal in household waste: Syringes must be disposed of through the medical waste management system.
• Safe waste transport: Safety boxes must be transported to medical waste disposal centers.

نکات ایمنی برای کادر درمان

• Full staff training: Nurses and doctors must receive proper training on injection and safe syringe disposal.
• Prevention of needle‑stick injury: Using safe techniques to prevent accidental needle penetration.
• Use of protective equipment: Gloves, mask, and gown are necessary in certain situations.
• Incident reporting: In case of needle‑related injury, it must be reported immediately and medical action taken.
