(5)


Indications

Alternatives
Potential Outcomes from the injection procedure
 

9

What three things are involved in documenting patient's consent to injection?


Sign a consent form
Third party should witness the patient’s signing
Consent is kept in the patient’s chart
 

10

At what angle should you inject intradermally?  What are the uses of these injections?  What guage needles for this?

~15 degrees


Used primarily for diagnostic purposes (allergy, TB, Candida) or applying local anesthetics
 


Usually uses small syringes and small gauge needles
 

11

What are 3 types of cutaneous injections?

Intradermal (ID)           
Subcutaneous (SQ)
Intramuscular (IM)
 

12

ID injections usually create a _____ on the skin.  Common sites inlude:   _______ and ______

Wheal

Arms and back

13

At what angle should a subcutaneous injection be administered?

What would this be used for and what is the absorption speed?

 

Needle size?

45 degrees


Allows for slow sustained absorption of medications, such as insulin, and  opiates
 


uses a variety of syringe and needle sizes, depending on the medication being used. 
 

14

Common sites of SQ injections>>

Abdomen

Lateral and posterior upper arm

Anterior Thighs

Ventrolateral gluteal region

(Anywhere with a nice juicy layer of subcutaneous fat)

15

At what angle should intramuscular (IM) injections be given?

What must be done with this that is not necessary with other injections covered in this set.

90 degrees


Should aspirate first, then inject medication...
... No blood, continue with injection
... Blood present-  withdraw slightly and redirect the needle, then inject; if needle comes out of skin, then start over. 
 

16

What are some examples of things that IM injections are commonly used for?


Includes vaccines such as Hep A/B, MMR,DPT Pentacel,  tetanus, B12, epinephrine, opiates, promethazine.
 

17

Common injection sites for IM?

Deltoid

Gluteus Medius

Vastus Lateralis

Rectus Femoris

Gluteus Maximus

Luke

18

What are some complications of injections?

Quite a few, so discuss


ÒVasovagal syncope
ÒSkin infection
ÒToxic rxn. to local anesthetics
ÒHematoma formation
ÒNeuritis
ÒRebound pain
ÒUnintended intravascular delivery
ÒPneumothorax or Compartment syndrome
 

19

What are the indications for joint injections?

DIAGNOSTIC

1.Acute or chronic symptoms present
2.Diagnosis is unclear or needs confirmation and
3. consideration of other diagnostic modalities has been made
4.Septic arthritis has been ruled out

THERAPEUTIC

1.Acute or chronic symptoms are present
2.After the diagnosis and therapeutic plan have been made
3.After consideration of obtaining radiographs

20

What are joint injections used for?


ÒAspiration/Arthrocentesis of fluid from a grossly swollen joint for pain relief or assessment of the synovial fluid (i.e. dx of gout, arthritis and joint infections)
ÒDelivery of local anesthetics for pain relief
ÒDelivery of corticosteroids or visco-supplementation (hyaluronic acid) for suppression of inflammation and improved ROM
 

21

Absolute contraindications of therapeutic joint injections?

Local cellulitis

Septic arthritis

Acute fracture

Bacteremia

Joint prosthesis

Achilles or patella tendinopathies

History of allergy or anaphylaxis to injectable pharmaceuticals or constituents

More than 3 previous corticosteroid injections within the past year in a single joint*.

__________________: 27-30 gauge 1/2inch needles,

                       1-3 cc syringes

___________________: 22-25 gauge 1.5inch needles,

                     1-10cc† syringes

__________________: 18-20 gauge 1.5 inch needles, Sterile

                      3-60cc syringes, hemostat, culture tubes

Anesthesia

Injections

Aspiration

23

What does epinephrine do with regard to lidocane?

Makes it stay put! Due to vasoconstriction cannot do on fingers, nose, hose (penis) toes, and earlobes.  (the mnenonic kind of falls apart there at the end)

24

How is lidocaine administered?

What is its duration?

What can it cause besides local anesthesia?


ÒLocal Cutaneous infiltration (lac repair, skin biopsy), field blocks
ÒQuick onset, short duration (30-60 minutes)
ÒCan cause vasodilatation:  Use if vascular disease is present or pt. is immuno-compromised or in contaminated wounds
 

25

What is the duration of bupivacaines?  What is a problem with this?  When might one use it though?


ÒLonger duration, but 4x toxicity than lidocaine; may cause cardiac arrythmia, contraindicated in pregnancy
ÒNerve blocks, when more time is needed 
 

26

Instructions for injecting anesthesia?


ÒUse the smallest needle possible (27-30gauge)

To minimize pain:

ÒWarm the anesthetic in your hands before injecting
ÒBuffer if lidocaine is used
ÒGently pinching or vibrating the skin
ÒInject rapidly thru skin into the Sub Q level
ÒInject the anesthetic slowly and steadily while withdrawing the needle

27

What two major condition types are treated with corticosteroids?  What are examples of each?


ÒArticular Conditions treated with steroids include: RA, OA, Gout and

     Tendonitis, Neuritis, Tender Points

28

What are some bad consequences of corticosteroids?

ÒMay weaken tendons or ligaments
ÒPost-injection (Steroid) Flare (4%)
ÒInfection or bleeding into a joint
Ò Tendon rupture
Ò Facial flushing, skin atrophy and/or

     depigmentation,

ÒHypersensitivity  rxn., transient paresis

29

What are the elements of a procedure note?  This one is for you Michael Plump.

 

(11 things)

A clear but succinct description of procedure performed:

1.Patient ID: Name , sex and DOB

10.Disposition of the patient: IS pt. stable, then what?  Sent home, admitted into hospital, taken to surgery?? Also any directions given to the pt., such as wound care, signs of infections, etc.

30

Choose the type/angle/location of injection and the syringe size, needle size and length for each of the following:

  3. Adult patient requiring a flu shot (1cc)
  4. Adult patient requiring  125mg  (1 cc)of antibiotic Ceftriaxone, mixed with 1 cc of lidocaine)

  1.  

31

For these, also decide on what meds to use.?

  1. Patient has a 1 inch clean laceration on his arm.  You plan to place 4 sutures. 
  2. Patient has a ¾ avulsion type  laceration near the tip of his finger.  He will need 4 sutures to hold in place.
  3. Patient suffers from chronic pain and swelling of his right elbow.  There is no effusion.  
  4. Patient comes in with an effusion of his right knee, you suspect Gout. What do you do?
