A

Start trying distally then move proximally as needed

29
Q

Advantages and disadvantages of central venous access?

A

Advantage:
good for reuse in hospital setting
they don’t collapse easy

disadvantages:
they require xray to confirm placement
cannot be used with other procedures like CPR
they risk things like air embolism, rupture, etc

30
Q

Which type of access is not one that paramedics will use but may run into in transports between hospitals?

A

Central Venous Access

31
Q

What is a PICC and when is it usually used?

A

Its a Peripherally Inserted Central Catheter; typically used in children with long hospital stayed; it is a long thin tube that is inserted in a peripheral venous access but threads to a central vein (we wont be inserting these)

32
Q

What is a Colloid and what are 4 common ones?

A

Colloidal solutions contain large proteins that cannot pass through the capillary membrane. They help maintain vascular volume (not usually given in prehospital care)

  • Plasma protein fraction
  • albumin (each gram given can retain 18mL of H2O in blood)
  • dextran
  • hetastarch
33
Q

What is are Crystalloids?

3 types of concentrations?

A

Crystalloids are the primary out of hospital care IV solutions given, they are a combo of electrolytes and water.
(solutions measured by “tonicity”)

Isotonic solutions: Equal tonicity to blood plasma
Hypertonic solutions: Have higher solute concentration (makes fluids move out of cells)
Hypotonic solution: Have lower solute concentration (makes fluids move into cells)

To make sense of fluid motion remember that water is going to move towards whichever side has more solute (like salt and water) (to hyper is like pooring in salt to soak up water while hypo is like pooring in a bunch of water into salt pockets.

34
Q

3 Most commonly used IV fluids and what are they?

A
  1. Lactated Ringer’s (Hartman’s Solution) - Isotonic solution containing sodium chloride, potassium, chloride, calcium chloride, and sodium lactate in water. (isotonic electrolyte solution)
  2. Normal saline solution - Isotonic electrolyte solution with 0.9% sodium chloride in water.
  3. 5% dextrose in water (D5W) - hypotonic glucose solution used to keep a vein patent and to supply calories needed for cellular metabolism.
35
Q

Should you ever warm or cool IV fluids?

A

Yes you can warm or cool IV bags to lower or raise PT body temp; either a fridge or heater can be used or the trucks heater/ac

36
Q

What is the most desirable fluid for replacement?

A

Whole blood; it is seldom used in ambulance though because it is a precious commodity and usually saved for mass casualty incidents or helo-air care

37
Q

3 pieces to IV packaging? (bags)

A
  • label
  • medication administration port
  • administration port
38
Q

Parts of macro and micro drip tubing and brief description: (8)

A
  • spike (sharp plastic piece that pierces the IV admin port)
  • Drip chamber (clear, squeezable chamber usually 3/4 full that allows you to see the drip rate)
  • Drop former (plastic piece that comes through the top of the drip chamber and is either very narrow or a little wider depending on micro or macro)
  • Tubing
  • Clamp (is able to immediately stop flow, also prevents air entering when bag is changed or backflow of fluids/meds)
  • flow regulator (allows for constant flow monitoring; rolled toward bag increases drip flow, towards pt decreases drip rate)
  • medication injection port (port that allows for hypodermic needle to inject meds into ; some models dont need hyperdermic needle)
  • Needle adapter (rigid plastic device designed to fit into the hub of an intravenous cannula)
39
Q

3 basic types of IV cannulas:

A
  • Over-the-needle catheter (IV catheter or cannula)
  • Hollow-needle catheter
  • Plastic catheter insert through a hollow needle
40
Q

Micro VS Macro drip rate per 1mL

When would you want to use them?

A 
Microdrip = 60 drops per 1mL
Macrodrip = 10 drops mer 1mL

Micro is good for when you need to watch how much fluid you give your pT

Macro is good for fluid replacement in situations like shock, or hypotension

41
Q

Over-the-needle catheter is also called the?

4 parts include?

A

IV catheter or cannula and it is a semi flexible catheter enclosing a sharp metal stylet; hollow; beveled

  1. metal stylet (needle)
  2. flashback chamber (lets you see blood enter when you’ve entered the vein, confirms placement)
  3. Teflon catheter (slides over the metal stylet into a successfully punctured vein
  4. Hub (on back of teflon catheter, recieves the needle adapter of the admin tubing once removed from the metal stylet.
42
Q

For peripheral venous access which IV cannula is preffered? why?

A

over-the-needle catheter is preferred because it is easier to place and anchor; permits freer movement.

43
Q

Which IV cannula is better for children or Pts with smaller/delicate veins?

A

Hollow Needle Catheter

44
Q

Hollow Needle Catheter is also called? Describe it?

A

Winged or Butterfly Catheters (because they have wings for guidance); they do not have a teflon tube and instead just use the stylet and secure it

45
Q

Catheter inserted through the needle is also called what? Desribe it.

A

AKA - intracatheter

It is a Tephlon catheter that is inserted through a large metal stylet used in the hospital setting to implement central lines (we will not use these)

46
Q

What are the different uses for a 22 gauge, 20 gauge, and (18/16/14) gauge?

A
  • 22 gauge (small) is good for fragile veins (old and young)
  • 20 gauge (medium) is good for average adult that does not need fluid replacement
  • 18/16/14 gauges are used to increase volumes or viscous meds.
47
Q

Blood can only be given by what gauge or larger?

A

16 gauge or larger

48
Q

On what side of the intended injection site do you place the venous constricting bang? What is maximum amount of time you should leave the band on for?

A

On the proximal side of injection side (to stop venous return and engorge veins); it should be left on no longer than 2 minutes

49
Q

What might you want to do after injection of IV catheter but before connecting an IV tube?

A

Take a venous blood sample

50
Q

8 steps of Peripheral Intravenous access?

  1. Examine IV fluid for clarity and exp date
  2. Spike the IV bag
  3. Squeeze fluid into drip chamber to fill line
  4. Open clamp/flow regulator and flush solution through tubing to remove any air bubbles
  5. Shut down flow regulator and replace cap over the needle adaptor (remember if contamination occurs this must be restarted with new equipment)
52
Q

What should be placed on the label that goes onto the IV bag?

A
  • Date and time initiated

- Person initiating the IV access

53
Q

All 12 steps in order of Intravenous access in the hand, arm, leg: (step 6 is insert IV cannula, try to remember what comes before and after)

54
Q

When inserting an IV should you pinch or pull skin taught?
Bevel?
Angle?

A
  • pull skin taught to stabilize the vein and keep it from rolling
  • Bevel up
  • Insert at 10 to 30 degree angle

(continue until you feel the “pop” of entering the vein and blood go into the flashback chamber)

55
Q

When inserting a catheter, how far past the needle end should you insert it?

A

0.5cm

56
Q

After you insert the catheter with the stylet still in, how do you take the stylet out?

A

Once catheter is inserted, tamponade (press down slightly) at the catheter tip to prevent blood from flowing from the catheter and or air from entering into the circulatory system as you remove the stylet.

57
Q

When you need to continue IV therapy, at what mL do you start to prepare a new bag?

A

When your current bag gets around 50mL you can prep the new bag

58
Q

What is an intravenous bolus?

A

involves injecting the circulatory system with a concentrated dose of medication through the medication admin port of an established IV

59
Q

Intravenous infusion is also called what? what is it?

A

AKA “Piggybacking”

Deliver a steady, continual dose of medication through an existing IV line

60
Q

If IV infusion is premixed, what should you check the label for? (4)

(if its not premixed you should put this info on the bag label you put on)

A
  • Name of med
  • Total dosage in weight mixed in bag
  • Concentration (weight per single mL)
  • Expiration date

(if its not premixed you should put this info on the bag label you put on)

61
Q

what is a herapin lock?

A

A herapin lock is a peripheral IV port that does not use a bag of fluid. It is for Pts that need the occasional bolus but not a continuous flow of fluids or meds

62
Q

What should be injected into a herapin lock following meds and why?

A

After meds inject sterile saline to fill the port and keep it open

63
Q

3 types of venous access devices?

Placed into what kind of veins and why?

A
  • Tunnel
  • Medication port
  • Peripherally inserted central catheter (PICC)

placed into large veins because they clot less easily and can remain in place for a long period of time

64
Q

Electromechanical infusion pumps are?

A

devices that permit precise delivery of fluid and or medication through electronic regulation

65
Q

2 types of electromechanical infusion pumps?

A
  1. infusion controllers : gravity flow devices that regulate the fluids passage through the pump
  2. Infusion pumps : deliver fluids and meds under positive pressure.
66
Q
