Types of Inoculation injuries
   Mucous membrane

   Contamination or splashing
    of the mucous membrane
    with blood or body fluids
   eyes, nose, mouth or
   conjunctiva with blood or
    body fluids

Inoculation Injuries in General Dental
practice (Safer Needles Network 2006a)

   Large number of injuries
    occur during administration
    of anaesthesia

   However , many injuries
    occur after the injection has
    been carried out
Common Injuries in Dental Practice

   During needle re -sheathing / removal

   During Surgery decontamination

   During Instrument tray clearing

   Incorrect placement of syringes
Blood Borne Viruses

   Blood borne viruses (BBV) are viruses that
    some people carry in their blood and which
    may cause severe disease in certain people
    and few or no symptoms in others. The virus
    can spread to another person, whether the
    carrier of the virus is ill or not.
Blood borne Viruses

 Hepatitis B (HBV)
 Hepatitis C (HCV)
 H.I.V
Hepatitis B Virus (HBV)

   Blood-borne viral infection that can be
    prevented through vaccination.

   The hepatitis B virus (HBV) causes hepatitis
    (inflammation of the liver)

   Can also cause long-term liver damage
Hepatitis C (HCV)

   Virus that can cause long-lasting infection
    and can lead to liver disease.

   There is no vaccination to prevent HCV.
Human Immunodeficiency Virus

   Causes Acquired Immune Deficiency
    Syndrome (AIDS).

   HIV destroys the body's ability to fight
    infection by attacking the immune system.

   This results in infected individuals becoming
    susceptible to opportunistic infections.
Risk of BBV transmission

        Hep B 33.3% (1 in Hep C 3.3 % (1 in HIV 0.33% (1 in
               3)               30)              300)
 How much   blood is required to
  transfer a blood-borne virus?
   As little as 0.00004 ml from an infected

               A blue needle holds 0.1ml
Body Fluids

   High risk
    –   Blood
    –   Amniotic fluid        –   Pericardial fluid
    –   Vaginal secretions    –   Synovial fluid
    –   Semen                 –   Saliva - dentistry
    –   Breast milk
    –   Cerobrospinal fluid
    –   Peritoneal fluid
Increase risk of transmission depends on:

   How deep the injury is                   High Risk Activities:
                                             IV drug users
   Visible blood present                    Blood transfusion pre-1991
                                             Residence in Sub Sahara
   Needle from source patient’s              Africa/Far East

         Never attempt to separate a needle and syringe;
          discard as one unit*.

         Store sharps containers at waist level or above, NEVER

         ALWAYS out of reach of children and vulnerable adults.

         Use temporary closure mechanism when container not

         Complete location sticker on sharps container and sign
          and date at assembly, locking and disposal.

     If a needle and syringe must
      be separated, the appropriate
      slot on the sharps container
      should be used to remove the
      needle from the syringe.

      absolutely unavoidable, a
      needle guard should be used.

     The one-handed technique
      can be used if staff are
      trained and competent to do
Policy and Procedure
   Each practice should have clear guidelines including :

   Inoculation injury management policy

   Flowchart for assessing and dealing with needlestick injury

   Programme for Hepatitis B immunisation

   Appropriate PPE

Individuals Exposed To Blood Borne Viruses
in Health Care Settings

   Any person exposed to the risk of blood borne viruses in any
    healthcare setting (including a domiciliary care situation) should
    be assessed and managed according to the principles laid out
    in the guidance provided by Occupational Health or A & E
    department at Doncaster Royal Infirmary.

   Support will be available to the individual during and after the
    incident. This support can be accessed through several sources
    including line management, Human Resources or Occupational
First Aid Percutaneous injury

   Aim to reduce bio burden
o   Wash under running water
o   Apply downstream pressure to help
    extrude infectious material
o   Apply waterproof dressing

   Report and document incident to
o   Seek advise from Occupational health

o   Do not squeeze , suck or scrub area
First Aid Mucous Membrane

   Flush affected area with
    copious amounts of
    cold water

required at Occupational
     Health or A&E
 Details of injury
 Patient’s name
