Objectives
Identify the types and sizes of needles Identify the uses for needles versus the using needle-less system Describe what are “safety engineered devices” Identify the use for the blunt needle (filtered and non filtered) Differentiate the types and sizes of syringes (leur lock vs slip tip) Demonstrate aseptic technique to open needle, non-needle and syringe
packaging Demonstrate aseptic technique to connect needle or non-needle and
syringe Demonstrate the correct aseptic technique to withdraw fluid from a vial
or glass ampoule Demonstrate correct technique to inject fluid Demonstrate correct mapping technique for administering an IM
injection Demonstrate correct mapping technique for administering a SC
injection Demonstrate correct disposal of sharps and syringes.
Safety Engineered Devices
A device that has a built in sharps injury protection mechanism such as an attached sheath covering the needle or scalpel after use or needles that retract after use.
Other types of safety devices include blunt needles or needle-less systems for access
Needles versus Needle-less System
When do needles and syringes get used? Skin Injection – IM, SC, Intra-dermal, hypodermoclysis, IV
insertion Reconstitution – mixing medications, transferring medications to
IV bags, IV push medications & fluids Syringe only – flushing catheters Needless System – connecting IV lines, sample collection from
arterial lines or venous catheters (central line port cap), irrigation and flushing, injecting medication / saline into IV tubing port with plastic cannula, withdrawing fluid / blood from venous / arterial access device via interlink cap / non-needle system from port
Needle Colour Codes
2 Styles of Safety Engineered Devices in AHS
Eclipse Available in small needle
lengths (< 1 inch) & longer needle length (1-1 ½ inch) as well as sizes from 30g to 18g.
Available in device used with slip tip syringes in needles 25-30 g. This has a metal strip seen at the hub.
SafetyGlide Available in needle sizes
from 30 g to 18 g. Not available in small needle
lengths < 1inch. Used in Insulin, TB, & Allergy
style needles. This system has a slightly different closure but is still called SafetyGlide.
Red Blunt Fill Needle (with or without filter)
Never Inserted into patient Never inserted into IV tubing (will destroy the membrane of the
needle-less tubing system). Withdraws from multi or single dose vial or ampoule Puncture stopper of vial at 90º angle to minimize risk of catching
internal wall of vial stopped. Remember, to insert equal volume of air to amount being removed from vial.
May be used to add medication to IV bag or minibag Discarded into sharps container Filtered Needles – use when withdrawing from glass ampoule
Withdrawing from Vial or Ampoule
Twinpak
All in one design
Activation of Safety Cover
Safety Glide
Eclypse
Syringes
Leur Lok Has a secure connection
where the tip is threaded for a locking fit and is compatible with needles, catheters and other devices
Available in 1, 3, 5, 10, 20 & 60 cc sizes
Slip Tip Has no locking connection Available in 1, 3, 5, 10, 20 &
60 cc sizes
Safety Lock Syringes
Locking device on syringe to cover needle completely. Needle retracts after use into a protective cover.
Syringes
TB & Insulin Syringes do differ
Preparing to Give an Injection
Know anatomy of site Avoid major blood vessels Avoid major nerves Awareness of landmarking of sites essential Considerations needed for size and age of patient
Average weight – you can reach SC tissue by using a ½” needle and inserting at a 90º angle
Thin – use a 5/8” needle and insert it at a 45º angle Elderly patients – consider using a shorter needle for IM
injections Select needle of sufficient length to reach targeted tissue (IM or
SC), depending upon size of patient Administer volumes appropriate to the target muscle
Injection Routes
Intramuscular (IM) – an injection into the muscle tissue (< 3mLs). Larger volumes require larger muscle (vas lat) while smaller volumes (up to 1 mL) can be injected into deltoid).
Subcutaneous (SC) – an injection into the fatty layer which lies beneath the dermis (≤ 0.5 – 1 mL). Less blood supply than of muscle tissue.
Intra-dermal (ID) – an injection into the dermis (0.1 mL). Used mostly to determine patient’s sensitivitiy (allergy testing, TB)
Injection Sites
Rotate sites frequently
IM Injections – Ventrogluteal Site
Landmarking
IM Injections - Deltoid
Landmarking
IM Injections – Vastus Lateralis
Landmarking
Standard Injection Procedure
Pediatric Considerations
Children can be very anxious or fearful of needles Assistance with proper positioning and holding of the child is necessary Distraction, such as blowing bubbles and pressure at the injection site
before giving the injection can help alleviate the child’s anxiety Children < 12 months of age – use the vastus lateralis muscle with a 3
mL syringe / 25 gauge / 1inch needle. Insert the needle at a 90º into the vastus lateralis. This site can be used for children older than 12 months of age with inadequate deltoid muscle mass.
Children > 12 months of age – use of deltoid (unless decreased muscle mass) with a 3 mL syringe / 25 gauge / 5/8 – 1 inch needle depending on the present muscle mass. Insert the needle at a 90º angle at the mid-portion of the deltoid.
Immediate disposal of syringe / needle into sharps container
Proper Positioning and Stabilization of Vastus Lateralis Muscle Children receiving a vastus lateralis site injection should be
stabilized in either of the following positions:
0-12 months of age
Positioning
Older child positioning
Prefilled Normal Saline Syringes
Designed for flushing vascular access devices PosiFlush XS saline filled syringes are terminally sterilized
following filling, labeling and packaging. Able to place on sterile field
Latex and preservative free Available in 3 mL, 5 mL, & 10 mL volume with leur lok Pre-filled saline syringes are NOT to be used for medication
administration as per the Institute for Safe Medication Practices Canada (ISMP) Syringe may not be correctly labeled once medication is
added Volumes may not be precise
Single use only device. DO NOT REUSE Dispose of unused solution One syringe / one patient only
Syringes & PSI
1 PSI (pounds per square inch) = 50 mmHg pressure Example: when a BP cuff is inflated to 200 mmHg pressure = 4 PSI A force of 3.5 PSI is required to activate a syringe plunger on most
small, prefilled syringes, so when a 3.5 PSI is applied to a 3 mL syringe a little over 29 PSI is generated as compared to a pressure of approximately 11 PSI when the same force is applied to a plunger of a 10 mL syringe.
Maintaining Sterility When Opening Packaging Maintaining sterility of contents when opening packages of
syringes and needles Quick observation of packaging for no tears/punctures or
water / fluid saturation that would render contents not sterile Notice of expiry date
Maintaining sterility of needles and syringes when connecting together Do not lay contents on counter once opened before
assembling needle to syringe
Correct Practice
Peel back the outer cover, ensuring not to contaminate the end of the syringe or needle.
Unacceptable Practice to Open Packaging
Do not “crack” open the packaging to retrieve contents
Contamination Risk
Do not lay opened contents on counter before assembling together as contaminates connecting areas on both the syringe and needle
Safe Disposal
Sharps Containers All needles & attached syringes Glass ampoules Blunt filled needles 5 Gallon Biohazard Pails Narcotics – squirt unused portion into pail (may be rendered
unusable). Do not drain down sink!
General Waste Empty plastic vials Empty syringes (no needle attached)
