SAEMS PRE- HOSPITAL PROTOCOLS 75 SCOPE OF PRACTICE ADMINISTRATIVE 2.9

I. PURPOSE This protocol defines the scope of authority afforded to prehospital providers in the performance of their duties with and without on-line medical direction. This protocol will enable the pre-hospital provider to understand all skills allowed without on-line medical direction, specialized skills allowed with proof of training and skills allowed only AFTER on-line medical direction has concurred.

II. DEFINITIONS A. STANDARD PERMISSIVE SKILLS Standard permissive skills are defined as skills that MAY be performed by pre-hospital personnel after approved initial training WITHOUT on-line medical direction. No telemetry or verbal orders are needed prior to the initiation of these skills for stabilization. Verification of on-going competency skill assessments must be obtained every two (2) years.

Page 6: Basic EMT IV Therapy Dawn Daniels RN, CCRN Tucson Medical Center Pre-hospital Program

B. EXPANDED SCOPE OF PRACTICE: NON PERMISSIVE

Expanded practice is defined as skills allowed by prehospital personnel with advanced training in the specific area. Prior approval of administrative medical direction authority is required. These skill MAY require on-line medical direction at the discretion of the medical direction authority.

Anatomy

Page 12: Basic EMT IV Therapy Dawn Daniels RN, CCRN Tucson Medical Center Pre-hospital Program

Introduction

• Knowing the anatomy will aid you in performing your skills, even when you cannot see the veins.

• After this block of instruction you should be able to differentiate between veins and arteries, and show where these items can be found.

Page 13: Basic EMT IV Therapy Dawn Daniels RN, CCRN Tucson Medical Center Pre-hospital Program

• What is skin?

• What is an artery?

• Where are arteries found?

• What is a vein?

• Where are veins found?

• What is blood?

• Question:

Some questions we’ll need to answer

Page 14: Basic EMT IV Therapy Dawn Daniels RN, CCRN Tucson Medical Center Pre-hospital Program

Skin• Covers the entire body and acts as a protective layer

between the body and the environment.

• The main functions of the skin are:– Protection from harmful influences

– Control of body temperature

– Conveyance of sensory impressions

• Some areas of the bodies skin are highly sensitive and the insertion of a needle in one area may cause a great deal of pain, while another area may be practically painless.

Page 15: Basic EMT IV Therapy Dawn Daniels RN, CCRN Tucson Medical Center Pre-hospital Program

•Besides epithelial cells and connective tissue cells, the skin also contains delicately entwined nerves and blood vessels.

Page 16: Basic EMT IV Therapy Dawn Daniels RN, CCRN Tucson Medical Center Pre-hospital Program

Blood Vessels• With the exception of capillaries, the

walls of the blood vessels consist of three layers, though the thickness or construction of the individual layers can vary according to the vessel type.

Page 17: Basic EMT IV Therapy Dawn Daniels RN, CCRN Tucson Medical Center Pre-hospital Program

Blood Vessels• The outer layer consists of connective tissue and

facilitates the fitting of the vessel into its environment.

• The middle layer is composed of smooth muscle containing elastic fibers.

• The inner layer consists of thin connective tissue. It is covered by a layer of single-layered endothelial cells.

Page 18: Basic EMT IV Therapy Dawn Daniels RN, CCRN Tucson Medical Center Pre-hospital Program

Arteries• The arteries are blood vessels which

transports blood away from the heart.• They are different in construction from the

veins in that they have an additional layer of an elastic membrane situated between the inner and middle wall layers.

Page 19: Basic EMT IV Therapy Dawn Daniels RN, CCRN Tucson Medical Center Pre-hospital Program
Page 20: Basic EMT IV Therapy Dawn Daniels RN, CCRN Tucson Medical Center Pre-hospital Program

Arteries

•Depending on the task and the location of the artery, its middle layer may be dominated by smooth muscle or elastic fibers.

Page 21: Basic EMT IV Therapy Dawn Daniels RN, CCRN Tucson Medical Center Pre-hospital Program

Arteries• When the heart pumps blood into the

arteries during the expulsion phase (systole), their high proportion of elastic fibers permits them to distend.

• During the relaxation phase (diastole) of the heart, they contract again, transporting blood on further.

• Arteries with muscle predominating are able to widen (vasodilation) or narrow (vasoconstriction) their diameter through contraction, thus enabling the amount of blood contained within them to increase or decrease with the demands of the body.

• Arterioles are the smallest arteries.

Page 22: Basic EMT IV Therapy Dawn Daniels RN, CCRN Tucson Medical Center Pre-hospital Program

Veins•The veins are the blood vessels which transport blood towards the heart.•The wall layers of the veins are thinner than those of the arteries, yet contain more connective tissue.•The muscle layer is less marked.

•The diameter of veins are larger than that of arteries.

Page 23: Basic EMT IV Therapy Dawn Daniels RN, CCRN Tucson Medical Center Pre-hospital Program

Veins• As a result of the thin layer of muscle the veins are not

able to move blood themselves. They are aided by the surrounding musculature around them.

• In order to prevent the blood from flowing back, some of the veins, especially those within the extremities, are equipped with venous valves.

• When the blood is flowing towards the heart, the venous valves lie flat against the venous wall. If the blood congests or starts to flow back, the valves close.

Page 24: Basic EMT IV Therapy Dawn Daniels RN, CCRN Tucson Medical Center Pre-hospital Program

Capillaries• Capillaries are the smallest blood

vessels in the body

• They are connected to the arterioles and into the venules, thus representing the link between arteries and veins.

Page 25: Basic EMT IV Therapy Dawn Daniels RN, CCRN Tucson Medical Center Pre-hospital Program

Capillaries• In contrast to arteries and veins, capillaries have neither a middle

or outer wall layer. They only have an inner layer, constructed of connective tissue and endothelial cells.

• The diameter of capillaries is very small because of they are so small they circulate in single file. This fact, and the thinness of their wall layer promote their ability toexchange material and Water with theirenvironment.

• The oxygen and nutrients contained within the blood are pressed out of them as a result of the blood pressure and passed off to the intercellular cavities.

• Carbon dioxide and metabolic products are absorbed by the blood in the exchange

Page 26: Basic EMT IV Therapy Dawn Daniels RN, CCRN Tucson Medical Center Pre-hospital Program

Blood• 4-5x thicker than water

• Liquid connective tissue

– Adults = 7% of patients weight • 4-6 Liters of blood

– Children = 9% of patients

weight

Page 27: Basic EMT IV Therapy Dawn Daniels RN, CCRN Tucson Medical Center Pre-hospital Program

Physical Characteristics of Blood

• Color range– Oxygen-rich blood is scarlet red– Oxygen-poor blood is dull red

• pH must remain between 7.35–7.45• Blood temperature is slightly higher than body

temperature (100.4)

Page 28: Basic EMT IV Therapy Dawn Daniels RN, CCRN Tucson Medical Center Pre-hospital Program

Functions of BloodTransportation – oxygen, nutrients, hormones,

heat, electrolytes.Carries away from the body tissues

- Waste matter- CO2

Protection – Vital role in our immune system; clotting mechanisms that prevent blood loss

Regulation – pH, body temperature, water

content

Page 29: Basic EMT IV Therapy Dawn Daniels RN, CCRN Tucson Medical Center Pre-hospital Program

Components of Blood

PLASMA – is the yellowish fluid of the blood and consists primarily of water (92%) and plasma proteins (7%)

Proteins – albumin and fibrinogenFORMED ELEMENTS – solid component of

the blood consisting of red blood cells, white blood cells, and platelets

BLOOD = 55% plasma

Page 30: Basic EMT IV Therapy Dawn Daniels RN, CCRN Tucson Medical Center Pre-hospital Program

Blood Plasma

• Composed of approximately 92 percent water

• Contains:– Nutrients, salt solution– Respiratory gases– Hormones– Proteins, Waste products

Page 31: Basic EMT IV Therapy Dawn Daniels RN, CCRN Tucson Medical Center Pre-hospital Program

Plasma Proteins

• Albumin – regulates osmotic pressure

• Clotting proteins – help to stem blood loss when a blood vessel is injured

• Antibodies – help protect the body from antigens

Page 32: Basic EMT IV Therapy Dawn Daniels RN, CCRN Tucson Medical Center Pre-hospital Program

Formed Elements“Types of Cells”

• Erythrocytes = Red Blood Cells

• Leukocytes = White Blood Cells

• Thrombocytes = Platelets

Page 33: Basic EMT IV Therapy Dawn Daniels RN, CCRN Tucson Medical Center Pre-hospital Program

Erythrocytes “Red Blood Cells”

• The main function is to carry oxygen• Anatomy of circulating erythrocytes

– Cells without a nucleus– Produced continuously in the bone marrow

from stem cells at a rate of 2-3 million cells per second.

─ Hemoglobin 95% of a red cell– Approximately 120 days life span

• Outnumber white blood cells 1000:1

Page 34: Basic EMT IV Therapy Dawn Daniels RN, CCRN Tucson Medical Center Pre-hospital Program

Leukocytes“White Blood Cells”

• These are complete cells, with a nucleus

• Crucial in the body’s defense against disease. Ingest pathogens & destroy

• Produce antibodies

• Can respond to chemicals released by damaged tissues

Page 35: Basic EMT IV Therapy Dawn Daniels RN, CCRN Tucson Medical Center Pre-hospital Program

Thrombocytes“Platelets”

• Cell fragments without nuclei that release blood clotting chemicals

• Life span of 5-9 days

• Needed for the clotting process

• Platelets and clotting proteins work together.

Page 36: Basic EMT IV Therapy Dawn Daniels RN, CCRN Tucson Medical Center Pre-hospital Program

So….Why should we allow EMT’s to start IV’s??

Page 37: Basic EMT IV Therapy Dawn Daniels RN, CCRN Tucson Medical Center Pre-hospital Program

Purpose of starting IV’s

• To deliver fluids

• To deliver medications

Page 38: Basic EMT IV Therapy Dawn Daniels RN, CCRN Tucson Medical Center Pre-hospital Program

Cellular Physiology

• Body Fluid– 1. Total body water = 60% of body

weight• Intracellular = 45% of body weight• Extracellular = 15% of body weight

– 2. Electrolytes• Cations = positive charge

– sodium– potassium– magnesium– calcium

Page 39: Basic EMT IV Therapy Dawn Daniels RN, CCRN Tucson Medical Center Pre-hospital Program

• Anions = negative charge– Bicarbonate– chloride

• Principles of electrolyte balance– Water follows sodium– Potassium > intracellular– Sodium > extracellular– Changes in ion concentration effect

muscle and nerve function

Page 40: Basic EMT IV Therapy Dawn Daniels RN, CCRN Tucson Medical Center Pre-hospital Program

• 3. Protein– Albumin– Plasma– Other

• 4. Fluid loss– Blood loss– Plasma loss– Nausea/vomiting/diarrhea– Sweating

Page 41: Basic EMT IV Therapy Dawn Daniels RN, CCRN Tucson Medical Center Pre-hospital Program

Movement of Body Fluids• Osmosis – the flow of fluid across a

semi permeable membrane (cell wall) from a lower solute concentration to a higher concentration.

Page 42: Basic EMT IV Therapy Dawn Daniels RN, CCRN Tucson Medical Center Pre-hospital Program

Isotonic – IV fluids that approximate the osmolaity of blood plasma. I.e.: 0.9% Normal Saline (note the biconcave shape of the cells as they circulate

in blood.)Hypotonic – IV solutions that have a lower osmolarity than blood plasma

thus drawing fluids into the cell. I.e.: D5W. (note the cells are visibly swollen and have lost their biconcave shape, and at 100 mOs, most have swollen so much that they have ruptured, leaving what are called red blood cell ghosts.

In a hypotonic solution, water rushes into cells.)Hypertonic – IV fluids that have a higher osmolality than normal blood plasma thus drawing fluids out of the cells and they get irritated when

infused.I.e.: D50 (note water has flowed out of the cells, causing them to collapse and assume the spiky appearance you see.)

Page 43: Basic EMT IV Therapy Dawn Daniels RN, CCRN Tucson Medical Center Pre-hospital Program

Types of IV Solutions

• 0.9% Sodium Chloride

• Lactated Ringers

• D5W

Page 44: Basic EMT IV Therapy Dawn Daniels RN, CCRN Tucson Medical Center Pre-hospital Program

0.9% Sodium Chloride• Also called normal saline• Isotonic solution of sodium chloride in

water• 9 grams of sodium chloride per liter• Indications

– Restore loss of water and sodium chloride• Fractures• Trauma• Dehydration• Hypoglycemia• Non-traumatic hypoperfusion

• Contraindications– Use with caution in CHF and pulmonary edema

Page 45: Basic EMT IV Therapy Dawn Daniels RN, CCRN Tucson Medical Center Pre-hospital Program

Lactated Ringers• Source of water, electrolytes, and

calories• Indications

– To replenish fluid and calories, and restore loss of electrolytes

• Trauma • Burns• OB• Non-traumatic hypotension• dehydration

• Contraindications– Use with caution in CHF, pulmonary

edema, and liver disease

Page 46: Basic EMT IV Therapy Dawn Daniels RN, CCRN Tucson Medical Center Pre-hospital Program

D5W

• Hypotonic solution of dextrose in water (50 grams of dextrose per liter)

• Indications– Directed by MD

• Contraindications– Head injury– Children

Page 47: Basic EMT IV Therapy Dawn Daniels RN, CCRN Tucson Medical Center Pre-hospital Program

Combinations of Normal Saline, Lactated Ringers, and D5W are

often common.

All fluids come in 250cc, 500cc, and 1000cc bags.

Page 49: Basic EMT IV Therapy Dawn Daniels RN, CCRN Tucson Medical Center Pre-hospital Program

Assemble and prepare the necessary equipment

You will need:

The correct IV solution

The correct administration set

An IV catheter

An IV start pack

Tourniquet

Alcohol prep

Opsite or equivalent

Tape

Page 50: Basic EMT IV Therapy Dawn Daniels RN, CCRN Tucson Medical Center Pre-hospital Program

Inspect the container and solution

• Check the label and the expiration date

• Look for tears in the bag

• Assess the clarity of the solution; if it is not clear – DO NOT USE IT!

• Look at the pull-tab and make sure that it is intact

Page 51: Basic EMT IV Therapy Dawn Daniels RN, CCRN Tucson Medical Center Pre-hospital Program

Types of administration sets

• IV administration sets differ mainly in the drop factor

(the rate of flow they produce)

Page 52: Basic EMT IV Therapy Dawn Daniels RN, CCRN Tucson Medical Center Pre-hospital Program

Minidrip/Microdrip/Pediatric Drip

• Delivers 60 gtts (drops) per cc (ml). Used on all patients that fluids need to be restricted on. I.e.: heart failure patients, dialysis patients, and pediatric patients.

Page 53: Basic EMT IV Therapy Dawn Daniels RN, CCRN Tucson Medical Center Pre-hospital Program

Standard/Macrodrip• Delivers 10-20 gtts (drops) per cc

(ml). Used on patients that require a large amount of IV fluid. i.e.: trauma, overdoses, burns, heat related emergencies.

Page 54: Basic EMT IV Therapy Dawn Daniels RN, CCRN Tucson Medical Center Pre-hospital Program

Blood tubing• A “Y” shaped tubing that is also is a

10 gtts per cc set, but is used with NS for blood administration.

Page 55: Basic EMT IV Therapy Dawn Daniels RN, CCRN Tucson Medical Center Pre-hospital Program

Preparing the IV bag• Remove the protective tab from the

insertion port• Close the flow clamp on the administration

set• Remove the protective cap from the

administration set• Holding the port carefully and firmly with

one hand, insert the spike with the other hand

• Hang the bag and squeeze the drip chamber until it is half full

Page 56: Basic EMT IV Therapy Dawn Daniels RN, CCRN Tucson Medical Center Pre-hospital Program

Priming the IV tubing• Open the flow clamp. Hold the end of

the tubing over a collection container. Be sure to maintain the sterility of the tubing!

• Leave the clamp open until the IV solution flows through the entire length of the tubing, forcing out all air.

• After priming the tubing, close the clamp.

Page 57: Basic EMT IV Therapy Dawn Daniels RN, CCRN Tucson Medical Center Pre-hospital Program

IV Catheters

Page 58: Basic EMT IV Therapy Dawn Daniels RN, CCRN Tucson Medical Center Pre-hospital Program

Selecting the IV catheter• Two types of needless and catheters

are commonly used in peripheral lines:– Over-the-needle catheters– Winged-tip or scalp-vein needles

Page 59: Basic EMT IV Therapy Dawn Daniels RN, CCRN Tucson Medical Center Pre-hospital Program

IV catheters• The higher the number, the smaller

the gauge

• The larger the gauge, the more fluid that can be delivered

• The shorter the catheter the more fluid that can be delivered

Page 60: Basic EMT IV Therapy Dawn Daniels RN, CCRN Tucson Medical Center Pre-hospital Program

General rule of thumb for selection of size:

• Medical patient’s– Use at least a 20 gauge catheter– A 22 gauge can be used if the patient

has small, fragile veins

• Pediatric patient’s (NOT USED on ages SIX and UNDER)– Use 20-22 gauge

• Trauma patient’s– Use at least an 18 gauge catheter

Page 61: Basic EMT IV Therapy Dawn Daniels RN, CCRN Tucson Medical Center Pre-hospital Program

Selecting the site

• Peripheral veins – usually for short-term use (less than 3 weeks)– When choosing a peripheral vein both

arms should be assessed.– Large veins are best suited for

emergency infusions– Avoid arms with injuries, burns, open

sores. Call for medical direction for mastectomy side possible

– Start with a vein at the most distal site so you can move upward as needed for additional insertion sites.

Page 62: Basic EMT IV Therapy Dawn Daniels RN, CCRN Tucson Medical Center Pre-hospital Program

• EXCEPTION:In a code arrest use the antecubital vein as it is closer to the central circulation. Fluids and medications do not have as far to travel to reach the central circulation.

Page 63: Basic EMT IV Therapy Dawn Daniels RN, CCRN Tucson Medical Center Pre-hospital Program

The most favorable venipuncture sites are:

- veins in the dorsum of the hand

- antecubital vein

- basilic vein

- cephalic vein

Be sure the vein can accommodate the catheter used.

Page 64: Basic EMT IV Therapy Dawn Daniels RN, CCRN Tucson Medical Center Pre-hospital Program

Factors affecting site selection

• Type of solution

• Condition of vein

• Duration of therapy

• Cannula size

• Patient age

• Patient preference

• Patient activity

• Presence of disease or prior surgery, i.e.: mastectomy or shunt (Call for medical direction)

Page 65: Basic EMT IV Therapy Dawn Daniels RN, CCRN Tucson Medical Center Pre-hospital Program

Patient preparation

• TALK TO YOUR PATIENT. Explain what you are going to do

• Prepare equipment

• Check solution for correct type, valid expiration date, and clarity

• Place patient in supine position to decrease vasovagal reaction

Page 66: Basic EMT IV Therapy Dawn Daniels RN, CCRN Tucson Medical Center Pre-hospital Program

• Select site and catheter

• Apply tourniquet

• Cleanse site

Page 67: Basic EMT IV Therapy Dawn Daniels RN, CCRN Tucson Medical Center Pre-hospital Program

• Hold skin taut, by placing thumb on non-dominant hand 1-2 inches below intended insertion site and gently pull skin

Page 68: Basic EMT IV Therapy Dawn Daniels RN, CCRN Tucson Medical Center Pre-hospital Program

• Insert needle through the subcutaneous tissue at a 20-30 degree angle beside or directly into the vein, bevel up

Page 69: Basic EMT IV Therapy Dawn Daniels RN, CCRN Tucson Medical Center Pre-hospital Program

• Assess for blood return

• When blood return is obtained decrease the angle of the catheter and very carefully advance the needle and the catheter approximately ¼ inch to assure the catheter is in the vein

• A steady backflow of blood indicates a successful venipuncture

Page 70: Basic EMT IV Therapy Dawn Daniels RN, CCRN Tucson Medical Center Pre-hospital Program

• Pull needle back into but not out of the catheter. Advance the catheter into the vein while continuing to hold the skin taut

Page 71: Basic EMT IV Therapy Dawn Daniels RN, CCRN Tucson Medical Center Pre-hospital Program

• Release the tourniquet

• Gently place pressure over the vein above the catheter tip to prevent bleeding while removing the needle. Do not compress catheter!

Page 72: Basic EMT IV Therapy Dawn Daniels RN, CCRN Tucson Medical Center Pre-hospital Program

• Attach fluid source

• Regulate flow rate

Page 73: Basic EMT IV Therapy Dawn Daniels RN, CCRN Tucson Medical Center Pre-hospital Program

Arm boards• Arm boards should be used to support areas of

joint flexion or to restrain IV sites in extremely active patients or children

• Arm boards should be padded to maintain comfort and prevent nerve or tissue damage

• Normal joint configuration should be maintained by supplemental padding

• Tape should NOT be wrapped completely around the patient’s arm, nor should it be applied too tightly because it will act as a tourniquet, decreasing peripheral circulation distal to the IV site

Page 74: Basic EMT IV Therapy Dawn Daniels RN, CCRN Tucson Medical Center Pre-hospital Program

Complications of IV therapy

• The potential hazards of IV therapy range from minor to life threatening

• They may be associated with the venipuncture or with the infusion

• Lack of aseptic technique is a major cause of complications as it induces pathogens into the circulatory system

• Complications may be local or systemic

Page 75: Basic EMT IV Therapy Dawn Daniels RN, CCRN Tucson Medical Center Pre-hospital Program

Local Complications

Page 76: Basic EMT IV Therapy Dawn Daniels RN, CCRN Tucson Medical Center Pre-hospital Program

Site infections (Local contamination of insertion site)

• Signs and symptoms– Redness, warmth, tenderness, and swelling at

site– Possible purulent material

• Possible causes– Failure to maintain aseptic technique during

starting or removing IV catheter

• Actions– Remove IV and restart in unaffected arm

• Prevention measures– Maintain strict aseptic technique of IV insertion

Page 77: Basic EMT IV Therapy Dawn Daniels RN, CCRN Tucson Medical Center Pre-hospital Program

Clotting (Blockage at the end of the device in the patient’s vein)

• Signs and symptoms– Tenderness at IV site– Sluggish flow rate

• Possible causes– IV rate too slow to maintain patency of catheter– Activity of patient causes increase back-flow of

blood• Actions

– Remove IV and restart in another area• Prevention measures

– Maintain constant flow rate– Tightly secure all connections

Page 78: Basic EMT IV Therapy Dawn Daniels RN, CCRN Tucson Medical Center Pre-hospital Program

Hematoma (Raised, discolored area caused by leakage of blood at puncture site)• Signs and symptoms

– Tenderness at venipuncture site– Area around site appears “bruised”– Inability to advance IV

• Possible causes– Vein “blown” or punctured through other wall at time of

venipuncture– Leakage of blood from needle displacement

• Actions– Remove IV catheter– Apply pressure to area

• Prevention measures– Do not advance needle further if resistance is met on

venipuncture– Choose a vein that can accommodate size of IV catheter

Page 79: Basic EMT IV Therapy Dawn Daniels RN, CCRN Tucson Medical Center Pre-hospital Program

Infiltration (Leakage of IV fluids into surrounding tissues)• Signs and symptoms

– Swelling, tenderness above the IV site that may extend along the entire arm

– Decreased skin temperature around the site– Fluid continues to infuse even when vein is occluded– Back-flow of blood is absent– Flow rate is slower or stopped

• Possible causes– Catheter is dislodged from vein or vein is perforated

• Actions– Remove IV catheter– Apply ice (early) or warm (later) to aid absorption– Elevate extremity– Restart IV infusion above infiltration or in another limb

• Prevention measures– Check IV site frequently– Do not obscure area above site with tape– Restrict movement of limb by placing on arm board

Page 80: Basic EMT IV Therapy Dawn Daniels RN, CCRN Tucson Medical Center Pre-hospital Program

Phlebitis (Irritation along vein)

• Signs and symptoms– Area along vein is red, tender, and warm– Vein is hard and cord-like when palpated– Irritation increases with infusion

• Possible causes– Hypertonic solutions– Repeated use of same vein for therapy– Movement of catheter in vein– Catheter is too large or flow rate too rapid for size of vein– Clotting at tip of catheter

• Actions– Remove IV catheter– Apply warm packs– Restart IV infusion is a different limb

• Prevention measures– Use large veins for hypertonic solution infusion– Choose smallest IV needle for situation and size of vein– Stabilize the catheter to decrease movement in vein

Page 81: Basic EMT IV Therapy Dawn Daniels RN, CCRN Tucson Medical Center Pre-hospital Program

Systemic Complications

Page 82: Basic EMT IV Therapy Dawn Daniels RN, CCRN Tucson Medical Center Pre-hospital Program

Catheter embolism

• Signs and symptoms– Related to specific location of embolus:

discomfort, decreased BP, cyanosis, weak pulse, respiratory distress, altered LOC

• Possible causes– Rethreading stylet into catheter

• Actions– Apply tourniquet above IV site to discourage

further traveling of device into venous system

• Prevention measures– Withdraw catheter and stylet together is

venipuncture is unsuccessful

Page 83: Basic EMT IV Therapy Dawn Daniels RN, CCRN Tucson Medical Center Pre-hospital Program

Air Embolism

• Signs and symptoms– Respiratory distress– Unequal breath sounds– Weak pulse– Decreased BP– Loss of consciousness

• Possible causes– Disconnect between catheter and tubing thus allowing

air to be sucked in– IV tubing that runs dry or is not purged of air properly– Solution container empty

• Actions– Discontinue IV infusion– Turn patient to left side, head down– Administer oxygen

• Prevention measures– Purge tubing completely of air before infusion starts

Page 84: Basic EMT IV Therapy Dawn Daniels RN, CCRN Tucson Medical Center Pre-hospital Program

Circulatory overload• Signs and symptoms

– Patient discomfort– Neck vein engorgement– Increased blood pressure– Fluid in lungs; rales, shortness of breath

• Possible causes– Roller clamp loosened to allow “run-away” IV– Miscalculation of fluid requirements

• Actions– Slow or stop infusion rate– Raise head of patient’s bed

• Prevention measures– Double check IV rate ordered for size and

condition of patient– Administer oxygen

Page 85: Basic EMT IV Therapy Dawn Daniels RN, CCRN Tucson Medical Center Pre-hospital Program

Systemic infection

• Signs and symptoms– Fever, chills without apparent reason– Nausea, vomiting– malaise

• Possible causes– Contaminated IV devices or solution– Failure to maintain aseptic technique during insertion

• Actions– Remove IV catheter– Restart in another area

• Prevention measures– Examine fluid and container– Monitor vital signs– Maintain aseptic technique– Secure all connections

Page 86: Basic EMT IV Therapy Dawn Daniels RN, CCRN Tucson Medical Center Pre-hospital Program

What to do when infusion stops• Check IV site for infiltration• Check IV catheter (position of patients

extremity, the tip of catheter may be against the wall of vein, tape may be too tight)

• Check the flow clamp• Check the tubing• Check the air vent

– If one is required (i.e.: glass bottles)– Check to be sure the spike is pushed in far

enough into bag– Try flushing the line with 5-10cc of saline.** If the IV still does not run after all the above

have been checked, then it should be discontinued and restarted! **

Page 87: Basic EMT IV Therapy Dawn Daniels RN, CCRN Tucson Medical Center Pre-hospital Program

Changing the solution• Turn the flow clamp off

• Quickly remove the spike from the bag and insert it into the new bag (assure sterility!)

• Turn the flow clamp back on and regulate the rate

Page 88: Basic EMT IV Therapy Dawn Daniels RN, CCRN Tucson Medical Center Pre-hospital Program

Let’s do some drip calculations

Page 96: Basic EMT IV Therapy Dawn Daniels RN, CCRN Tucson Medical Center Pre-hospital Program

IV drip rate:

Volume to be infused (ml) X drip factor of tubing

gtts/min =

Time (min) to be infused

i.e.: 1000ml X 10

= 166 gtts/min

60min
