Compounding Sterile Products-indian-doctors

 

• Hospitals carry out unique activities, such as the preparation, handling, and disposing of hazardous drugs.

  A major responsibility of the pharmacy tech involves compounded sterile products (CSPs).

  Aseptic technique – the processes and physical preparation methods used by sterile compounding personnel to avoid introducing pathogens, into parenteral products.

  Compliance with sterile compounding and aseptic technique standards established by USP. 

  
  

• Sterile Supplies for IV Preparation and Administration

• Syringes and Needles: used for withdrawing or injecting solutions during the preparation of CSPs.

  IV push (IVP) – bolus administration; rapid injection of a medication.

  Syringes: made of glass or plastic; glass – limited use, expensive; plastic – less expensive, supplied in sterile packaging, disposable.

  
  

  Main components of a syringe:
• • Syringe tip
  • Barrel – contains calibration marks
  • Rubber-tipped piston plunger
  • Syringe Selection and Measurement
  • Technicians should choose the smallest syringe that is able to hold the desired volume; at least ¾ full.
  • Technicians should count the number of marks between labeled measurement units, to get the most accurate dose.
  • The volume of solution is measured at the point of contact between the rubber-tipped piston plunger and the inside of the barrel.

  • Needles
  • Needles are made of stainless steel or aluminum. The needle size is determined by length and gauge and the lengths range from 3/8 inch to 6 inches. Gauge refers to the diameter of the opening; the larger the gauge number the smaller the opening (or size of the lumen). 
  • 31-gauge (smallest bore)
  • 13-gauge (largest bore)
  • Parts of a needleeedle shaft
  • Needle lumen
  • Needle hub
