Gunshots…

6

Gunshot Victims

7

Firearm Related Injuries

• Gunshot wounds are either penetrating or perforating wounds

• Technical terms:– Penetrating gunshots are when the bullet

enters, but does not come out of the body.– Perforating gunshots are when the bullet

enters and exits the body

8

Perforating Gunshots

9

Penetrating gunshot

10

Entrance wound

• Surrounded by a reddish-brown area of abraded skin, known as the abrasion ring

• Small amounts of blood

11

Mechanism of Energy Exchange

• As bullet passes through tissue, it decelerates, dissipating and transferring kinetic energy to tissues– Cause of the injury

• Velocity more important than mass in determining how much damage is done– Small bullet at high speed will do more

damage than large bullet at slow speed

12

Mechanism of Energy Exchange• High velocity

– High powered rifles; hunting rifles– Sniper rifles

• Medium velocity– Handguns, shotguns– Compound bows and arrows (higher energy released)

• Low velocity– Knives, arrows– Falling through plate glass window, stepping on

things, bits flung by lawnmower

13

Medium & High Velocity

• These items are usually propelled by gunpowder or other explosive

• Faster the object, the deeper the injury• Causes damage to the tissue it impacts• Creates a “pressure wave” which causes

damage frequently greater than the tissue directly impacted

• If bone is struck, bone shatters and multiple bone fragments are dispersed

14

Low velocity

• Usually a result of items such as knives that are propelled by a person’s own power– Also includes objects inadvertently stepped on– Includes many objects a patient may be impaled

on• Damage usually limited to the area directly in

contact with the object

15

Types of Firearms

• Pistols– Revolver– Semi-Automatic

• Shotguns– Pump– Semi-Automatic

• Rifles– Bolt– Lever action

16

Pistols – Medium Velocity

17

Shotguns – Medium Velocity

18

Rifles – High Velocity

19

Projectiles – High Velocity

• Rifle bullets are designed to have much greater velocity than shotgun bullets

• Different size of casing provides more or less gunpowder

20

7 mm rifle shell – High Velocity• Bonded design for deep

penetration and 90%+ weight retention

• Streamlined design delivers ultra-flat trajectories

• Devastating terminal performance across a wide velocity range

• Unequaled accuracy and terminal performance for long-range shots

21

Projectiles – Medium Velocity

• Shotgun ammunition can be a variety of kinds

• Slugs are one large bullet in the shell

• Some shells contain numerous pellets of various sizes

• This can influence patient’s injuries

22

Shotgun Shell – Medium Velocity

12 Gauge Shotgun Slug 12 Gauge Shotgun with #6 shot

23

.38 caliber pistol ammunition

• Controlled expansion to 1.5x its original diameter over a wide range of velocities

• Heavier jacket stands up to the high pressures and velocities of the highest performance handgun cartridges

24

Compound Bows and Arrows – Medium Velocity

25

Arrowhead Types – Medium Velocity

Target tips Broadhead

26

Arrow injuries

27

Another ouch….

• How would you stabilize and dress these wounds?

28

Principles of Wound Care• What are principles of wound care for the two

previous wounds?– Scene safety– Control bleeding

• Usually little to no bleeding while object still impaled

– Prevent further damage• Immobilize the object in place

–Gauze, tape, whatever it takes– Reduce infection

• Prevent further contamination

29

Different Types of Knives

• Knives come in a wide variety of shapes and sizes

• The type of knife can influence the injuries a patient may have

• Hilt/handle of knife does not necessarily tell how long the knife is

30

Anticipation of Injury

• Trajectory may be straight or not• Knowing anatomy helps anticipate organ

injury• Anticipating organ injury helps in knowing

what signs and symptoms to watch for• Anticipation of injury = proactive care

– Head wound = monitoring level of consciousness– Chest wound = assessing lung sounds– Abdominal wound = assessing internal blood loss

31

Stabbings

• 15 year old stabbed in the head at a London bus stop

• Cannot determine from the outer wound what the damage is internally

• Assume the worse• Stabilization of impaled

objects extremely crucial

32

Police Officer StabbingWhat injuries do you suspect?

33

Organ Injury

Patient was shotwith a MAC-10

machine gun and sustained aliver injury

Lap sponge under fold of skin

Liver surface with injury noted to organ

34

Scene Safety

• Attacks at both Columbine and Virginia Tech had well armed offenders

• EMS and Police must work through a unified command structure to provide maximum safety

35

Scene Safety

• Not exclusive to schools– Fort Hood, TX Shooting (2009)– Colorado Church Shootings (2007)– Queens, NY Wendy’s Shooting (2000) – Atlanta Day Trader Shooting (1999)– San Ysidro McDonald’s Shooting (1984)

36

Management Goals

• Short on scene time! Under 10 minutes!• Immediate life threatening issues addressed• Rapid move to ambulance• Good BLS skills• ALS treatment while enroute• Transport to Level 1 Hospital, if under 25

minutes• Transport to closest hospital if Level I >25

minutes away• Consider helicopter in unique situations

37

Management Goals

• Critical patients need rapid transport per SOP• Difficult to assess internal damage in the field• Stop any visible bleeding that could cause

hemorrhage hypovolemia• Address airway issues

– Tension Pneumothorax chest decompression– Suction to keep airway open– Intubate to secure the airway

• Surgery is the answer to critical gunshots

38

Management Goals

Focus on the basics

If there is a hole – plug itIf there is bleeding – stop it

If they can’t breathe – ventilate

39

Scene Management Review

• Columbine shooting showed areas that police needed to address– Previously philosophy for police was to secure

area and wait in perimeter for SWAT to arrive– But, this allowed shooter to continue

unobstructed– Police now form team early and enter the building

to engage shooter providing containment– Prevents shooter from continuing rampage

40

Thoughts - Scene Management

• EMS/Fire has not been as proactive• Staging vs. Entry

– Some agencies are sending first patrol officers in to engage/contain offender

– Next group in is two medics with two police escorts

– Treat patient and move on until running out of supplies, then retreat to remove victims

– Provide aggressive care and move fast– Departmental policies need to be reviewed

• Preferable to review with police input

41

Scene Management

• Use MABAS to get more help early• Activate the Multiple Patient Incident Plan• Multiple staging areas

– Explosives could be set for responders– Easier deployment to variety of areas– Downside is less scene control

42

Categorizing The Patient

• Perform scene size-up• Perform initial assessment

– Purpose – determine presence of life threats• Open airway/perform spinal precautions• Evaluate breathing• Evaluate circulation• Obtain AVPU and GCS scores• Obtain general impression

– Identify priority of transport

43

Region X

Field Triage Criteria For Assessing Trauma Patients

44

Patient Transport Decision

• Critical and Category I trauma patients

– Transported to highest level Trauma Center within 25 minutes

• Aeromedical transport remains an option especially in lengthy extrication and distance from the hospital

45

Categorizing The Critical Patient

• Systolic B/P < 90 x2– Pediatric patient B/P < 80 x2

• Blood pressure values taken at least twice and 5 minutes apart

• These patients transported to highest level Trauma Center within 25 minutes

46

Categorizing The Category I Trauma Patient

• Unstable vital signs– GCS < 10 or deteriorating mental status

• Best eye opening – 4 points max• Best verbal response – 5 points max• Best motor response – 6 points max

– Respiratory rate <10 or >29– Revised trauma score < 11

• Range 0-12 – 3 components added together

» Converted GCS (3-15 score converted to 0-4 points)» 0 - 4 points for respiratory rate» 0 - 4 points for systolic blood pressure

47

Categorizing The Category I Trauma Patient

• Anatomy of injury– Penetrating injuries to head, neck, torso, or groin– Combination trauma with burns > 20%– 2 or more proximal long bone fractures– Unstable pelvis– Flail chest– Limb paralysis &/or sensory deficits above wrist or

ankle– Open and depressed skull fractures– Amputation proximal to wrist or ankle

48

Patient Transport Decision• Category II trauma patients

– Transported to closest Trauma Center

• These are stable patients with significant mechanism of injury• You know they are stable because of frequent reassessment• There is the potential for these patients to become unstable

– Recognize that pediatric patients often pull you into false sense of security (but so can adults)

• Peds patients maintain homeostasis as long as possible and when compensation fails, they deteriorate fast

49

Categorizing The Category II Trauma Patient

• Mechanism of injury– Ejection from automobile– Death in same passenger compartment– Motorcycle crash >20 mph or with separation of

rider from bike– Rollover – unrestrained– Falls > 20 feet

• Peds falls > 3x body length

50

Category II Trauma Patient cont’d

• Mechanism of injury cont’d– Pedestrian thrown or run over– Auto vs pedestrian / bicyclist with > 5 mph impact– Extrication > 20 minutes– High speed MVC

• Speed > 40 mph• Intrusion > 12 inches• Major deformity > 20 inches

51

Category II Trauma Patient

• Co-morbid factors– Age < 5 without car/booster seat– Bleeding disorders or on anticoagulants– Pregnancy > 24 weeks

52

Category III Trauma Patient

• All other patients presenting with traumatic injuries– Fractures– Sprains/strains– Burns– Falls– Pain

• Provide routine trauma care– Honor patients request for hospital choice as

much as possible

53

Communication• Call early; update as needed

– Hospital staff and resources may need to be mobilized

• The more critical the patient, most likely the shorter the report– Give important details– Paint the picture head to toe– Just as important is to give tasks not completed

• Intubation versus bagging• IV access obtained or not

54

Abbreviated Radio ReportProvide department name, vehicle number and

receiving hospitalState, “this is an abbreviated report”Provide nature of situation and SOP being followedAge and sex of patientChief complaint and brief historyAirway and vascular statusCurrent vital signs, GCSMajor interventions completed or being attemptedETA

55

Fluid Challenges

56

Adult Fluid Challenge

• Adult fluid replacement is in 200 ml increments (replacement formula 20 ml/kg)

• Storage issues– IV bags are usually in ambulance, in bays– Fluid eventually are at ambient temperatures– 70° fluid into 98.60 body will cause core body

temperature to decrease– Hypothermia results– Cold patients become acidotic patients

57

Adult Fluid Challenge

• 200 ml increments– Formula is 20 ml/kg– Example

• 200 # patient = 100 kg–100 kg x 20 ml/kg = 2000ml fluid challenge

– Reassess your patient as you are passing the 200 ml mark

– Monitor breath sounds for fluid overload

58

Adult Fluid Challenges

• Vascular issues– Vessel damage results in extensive blood loss– EMS infuses Normal Saline– NS does not carry oxygen; NS solves volume issue

only– Volume can be filled, but patient still in distress

due to lack of oxygen carrying capacity (ie: blood)– Goal should not be to get a 120/80 blood

pressure, rather to stabilize

59

Adult Fluid Challenges

• If your patient’s blood is becoming pink, they need more blood in the system!

• EMS typically does not carry blood in the field• Important to accelerate transport to a facility

that can add the blood and do the surgery to repair the underlying problem!!!

• Good BLS skills are more important than ALS skills for these types of patients!

60

Pediatric Fluid Challenges• Pediatric shock protocol

– EMS carries Normal Saline– Formula 20 ml per kg for fluid bolus– Can be administered up to three times total or up

to 60 ml per kg total• Smaller container (patient size) means less

fluid means less oxygen carrying capacity• Example:• 30# patient = 14 kg (30 2.2)

– 14 x 20ml/kg = 280 ml fluid challenge

61

Fluid Challenge Calculations

• 6 year old patient weighs 66 pounds– 66 pounds = 30 kg– Fluid challenge of 30 kg x 20 ml = 600 ml each time

• 15 year old patient weighs 175 pounds– 175 pounds = 80 kg– Fluid challenge of 80 x 20ml = 1600 ml fluid

• 25 year old patient weighs 120 pounds– Adult gets fluid challenge in 200 ml increments

• 75 year old patient weighs 180 pounds– Adult gets cautious fluid challenge in 200 ml increments

62

Fluid Challenges

• Precautions– All patients need to be monitored for potential

CHF– Even a previously healthy patient can be thrown

into CHF • Too much fluid too fast

• Patient #2– DOA from self inflicted gun shot wound– Was going through a divorce and called patient #1

to come pick up the kids– When Patient #1 arrived, Patient #2 asked her to

step into the basement where he shot her multiple times and then turned gun on self

– Children’s grandparents had also been called to pick up the kids

71

Case Study #1

• Is this a Category I or II trauma patient and why?– Systolic B/P below 90– GCS less than 10– RTS less than 11– Penetrating injuries to head, neck, torso or groin

72

EZ IO

• Have you used one on a patient?

• High risk, low volume procedure– To retain competency need

review and practice

73

EZ IO

• Indications– Must meet all indications

• Shock, arrest, or impending arrest

• Unconscious/unresponsive to verbal stimuli

• 2 unsuccessful IV attempts or 90 seconds duration

74

EZ IO• Contraindications

– Fracture of the tibia or femur– Infection at insertion site– Previous orthopedic procedure (knee

replacement, previous IO insertion within 480)– Pre-existing medical condition (tumor near site,

peripheral vascular disease)– Inability to locate landmarks (significant edema)– Excessive tissue at insertion site (morbid obesity)

• Hold leg up off bed to allow excess tissue to fall dependently

75

EZ IO Equipment• Lithium drill

– Battery powered for 1000 insertions• Needle

– Blue needle – 25 mm (1) 15 G for patients over 88 pounds (40kg)

– Pink needle – 15 mm (5/8) 15G for patients between 7 and 88 pounds (3kg – 40kg)

• EZ connect tubing• Syringe• Saline to prime EZ connect tubing• Primed IV bag• Pressure bag/B/P cuff• Site prep material (ie: alcohol pad)

76

Equipment Case

Needle sizes used in Region X

EZ connect tubing

10 ml syringe with saline

77

EZ IO Procedure

• Prime EZ connect tubing with saline; leave syringe attached (for flushing)

• Locate and cleanse site– Proximal medial tibia

• Prepare driver and needle set; remove safety cap• Insert needle at 900 angle• Remove stylet• Attach primed EZ connect tubing• Aspirate then flush line with remaining saline• Remove syringe only and connect primed IV set• Confirm needle placement

78

Identifying Site

• Proximal medial tibia– 2 finger breadths below patella (to tibial

tuberosity) and 1 finger breadth medially from tibial tuberosity

– May or may not be able to identify the tibial tuberosity at 2 finger breadths below patella

– As patient is lying supine, legs tend to roll slightly outward

• This presents the flat surface of the tibia

79

Confirming EZ IO Placement

• Sudden lack of resistance felt

• Needle stands up by self• Bone marrow may be

noted on aspiration• No resistance to flushing• IV runs with pressure

applied to IV bag• No infiltration noted

80

81

Documentation OF EZ IO Insertion• Document usual IV insertion information

– Time of insertion– Size IV bag used– Site, needle length, needle gauge– Amount of fluid infused in the field

• Place fluorescent yellow arm band on patient’s wrist to indicate insertion (or attempt) of IO– Recommended to place on same side as insertion

site– Arm band used for successful and unsuccessful

insertions

82

• Complete PI form for every use of the EZ IO needle

• Submit PI form to the EMS coordinator with the EMS run report

EZ IO PI

83

Saline Lock/Extension Tubing• Indication

– To establish an extension line between the IV catheter and the IV tubing

• Allows hospital staff to change IV tubing with less disturbance to the inserted IV catheter

– To have access to circulation without the need for fluids

• Equipment– IV start pak– IV catheter– Macrobore extension set (7.25 inches)– 10 ml saline in syringe for priming tubing and flushing

• Routine medical care SOP states:– Establish 0.9 normal saline (NS) per IV/IO and

adjust flow as indicated by the patient’s condition and age

– May use a saline lock cap on IV catheter hub for stable patients (not needing fluid resuscitation)

84

Region X SOP - Saline Lock

85

• Note:– Saline lock is an older term

• Tends to mean a small cap device inserted into the proximal end of an IV catheter; no extra tubing

– Equipment to be used• Macrobore extension tubing with clave port

– 5-7 inches of tubing with a male end to connect to the proximal IV catheter

– Clave port on proximal end for connecting IV tubing or attaching a syringe

• Nowadays, if you say “saline lock” the macrobore and microbore tubing is the device the general hospital person would think you are discussing

Terminology Saline Lock – Extension Tubing

86

“Saline Lock” Procedure

• Establish an IV following sterile technique• Remove stylet• Insert distal tip of primed extension tubing/ saline

lock into IV catheter– If administering fluids, IV tubing should be already

attached to the extension tubing/saline lock• Adjust flow rate

• If IV line is precautionary, flush extension tubing/saline lock with 10 ml sterile normal saline– Remove syringe– Do not need IV tubing or IV bag

87

Extension Tubing/Saline Lock• Connecting to IV catheter

– Keep IV site as distal as possible• AC should not be your first choice

• We are requesting to start getting into habit of adding this extension tubing to all IV starts

88

IV Equipment for Saline Lock• If patient needs fluid, attach primed IV tubing with bag to

proximal end of extension tubing/saline lock

– Wipe off blue clave port with alcohol prep pad– Push in and twist primed IV tubing to connect – Adjust flow rate as indicated– Document time, type, and size IV solution hung– Distal tip of clave inserted into IV catheter

89

Extension tubing/Saline Lock In Place

• Extension tubing/saline lock properly secured– Insertion site not taped over– Clear view of insertion site through op-site/tegaderm

dressing – Access to port available– Can easily attach primed

IV tubing if need to begin fluid therapy

90

Improperly Secured IV Site

• Insertion site taped over• Gauze bandaging under tape

– Increased risk of infection

IV site properly covered with see through dressing

91

Extravasation of Medication

• To use the extension tubing/saline lock for infusion, must verify that the line is patent– Aspirate for blood return– Stop infusion if patient complains of pain/burning

Extravasation of IVP medication resulting in amputation of several fingers

92

Case Study #2

• 25 year old male shot in the chest• Police are on the scene• Patient sitting on ground, leaning against car• Several small casings on ground near victim• Patient bleeding from small chest wound left

anterior chest• Patient is anxious, pale, diaphoretic with

elevated respiratory rate

93

Case Study #2

• Patient alert and oriented x3• Complains of mild chest pain aggravated with

deep breathing• VS: 122/86, 90 – 20• Hole noted in the left anterior chest about the

3rd intercostal space– No air seems to be moving through the hole

94

Case Study #2

• What questions do you have?– Has the patient been searched?

• The patient had not been searched• A small pocket knife was retrieved by police

• Is there anything else to be done for assessment?– Check for multiple bullet wounds– Evaluate all sides of the patient

• A large wound was noted on the patient’s left back

95

Case Study #2

• Interventions required– Immediately seal the open wounds

• Dressing secured on 3 sides– Provide high flow oxygen via non-rebreather– Establish IV access– Contact Medical Control

• What Category trauma is this patient?–Category I – penetration of torso

96

Case Study #2 - Documentation

• “Upon arrival found patient handcuffed. States, “they shot me” a few minutes ago. Bleeding is controlled. Patient states only mild pain especially with a deep breath. IV, O2, monitor applied. Level I trauma center notified. Police informed of hospital destination.”

• What’s wrong with this documentation?

97

Case Study #2

• No description of injuries noted– Size, location, presence/absence of bleeding– Lack of documentation of gun used when

information is known• No documentation of 3 sided dressing applied• No documentation of response to treatment• Interventions (ie: IV, O2, monitor) do not need

to be reduplicated in the comments• No documentation of police in ambulance due

to patient being handcuffed

98

Case Study #3

• 911 call to scene for a domestic incident• Upon arrival, summoned to the back yard for a 23

year old female patient lying on the ground conscious and awake

• Patient states she was running out of the house and tripped down the stairs

• Tree branch noted impaled through right flank at level of umbilicus

• VS: 124/100; 120; 22; SpO2 98%; warm & dry• No active bleeding

99

Case Study #3

• What actions are necessary for EMS to take for:– Scene safety?– Initial assessment?– Interventions?– Reassessment?

100

Case Study #3• Scene safety

– Is the scene secured?– Where is the husband; who is with the husband?

• Initial assessment– Airway – open– Breathing – without distress although patient is upset– Circulation – warm & dry; capillary refill 1 ½ seconds;

pulse steady and palpable at the radial site– AVPU – awake, cooperative, anxious

101

Case Study #3

• Categorization?– Category I – penetrating object to torso

• Interventions– Secure impaled object, prevent further movement

• Manual control initially• Gauze padding around entrance site• Assess for exit wound

102

Case Study #3

• Reassessment– What internal injury is anticipated?

• Abdominal– Solid organ – bleeding– Hollow organ – spilling contents causing contamination– Punctured vessels hemorrhage

• Chest– Punctured diaphragm– Punctured lung– Punctured heart– Punctured vessels

103

Case Study #3

• Patient taken to OR• Stabilization maintained to prevent movement

of impaled object• Tree branch removed under direct

visualization• Abdominal cavity cleaned and flushed• Patient did well and was discharged 5 days

post-op

104

Case Study #4

• Responded to a call at a tavern for a person shot • Upon arrival, the patient lying on their right

side, blood noted under their head• Patient is breathing, radial pulse is palpable• They do not open their eyes; the patient moans

when touched; the patient withdraws• The bullet is visible in the wound• What is first things first?

– SAFETY, SAFETY, SAFETY

105

Case Study #4

• Patient was in a local bar• Was reported to be inebriated• Was shot with a .25 ACP (relatively weak

round; assailant is gone)• Patient slumped to ground from bar stool

• Describe your care• Score the GCS• What report do you provide to the ED?

106

• Need to log roll patient protecting C-spine

• Maintain clear airway• GCS

– Eye opening – 1– Verbal response – 2– Motor response – 4– Total GCS - 7

107

Case Study #4

• Cannot tell internal damage by external appearances only

• Patient had small bone fragments that were pushed into the brain

• Patient required neurosurgery evaluation

108

Case Study #4• Report

– Description of wound(s) noted including body region

– Include type of weapon used if information is available

– Include distance from weapon if available• Closer the range, the more energy that is

behind the bullet/shot the greater the internal damage

– Note basic care provided (IV, O2, monitor)

109

Case Study #5

• A patient presents as a walk-in to your department

• Approximately 2 hours ago, he was involved in a domestic disturbance

• Patient states his girlfriend hit him in the upper chest and he continues to have some pain and is now worried regarding the injury

• Awake and alert, vital signs stable

110

Case Study #5• You can’t assess what you can’t see – remove clothing• What injuries do you anticipate?

– Heart, lung, vessels– Trachea– Esophagus

Visible wound

Object viewed on x-ray

111

Case Study #5 – Operative View

• Impaled object after removal• Was near pulmonary artery but no damage• Knife missed all vital structures

112

Case Closure

• What saves lives when impaled/penetrating objects are involved?Age and condition of patient

• Younger patients and those in good health can tolerate the insult better

Rapid identification and transport form the field

Proper stabilization of the object to prevent further damage by movement

Rapid OR for direct visualization and repair
