13 Gunshot Wounds Injuries created by medium or high-velocity weapons

14 Mechanism of Injury

15 Gunshot wounds

16 Mechanism of Injury The physical event that caused an injury (knife wound, gun shot wound, motor vehicle accident, etc.)

17 Velocity Low velocity–knife Medium velocity–handgun, shotgun (generally less than 2,000 feet-per-minute) High velocity–rifle (generally greater than 2,000 feet-per-minute) Body region penetrated Exit wounds Mechanism of Injury: Penetrating Trauma

18 Wound ballistics (Kinematics)

19 GSW's : Ballistics Ballistics is defined as the science of the motions and impacts of projectiles Wounding capacity = kinetic energy deposited in the tissue Kinetic energy = mass times ( V1 squared minus V2 squared)* * V1 = impact velocity V2 = exit velocity (it is zero if the bullet does not exit) 19

20 Factors that contribute to tissue damage include: Bullet size: The larger the bullet, the more resistance and the larger the permanent tract Bullet deformity: Hollow point and soft nose flatten out on impact, resulting in a larger surface area involved. : Wound Ballistics: Medium and High velocity wounds

21 tissue damage continued: Semijacket: The jacket expands and adds to the surface area Tumbling: Tumbling of the bullet causes a wider path of destruction Yaw: The bullet can oscillate vertically and horizontally (wobble) about its axis, resulting in a larger surface area presenting to the tissue. Wound Ballistics: Medium and High velocity wounds

22 To what is cavitation (shock wave) related? Gunshot Wounds: Cavitation

23 Entrance and exit wounds Gunshot Wounds

24 The wound consists of three parts: Entry wound: Usually smaller than the exit wound Exit wound: Not all gunshot wounds will have exit wounds and on occasion there be multiple exit wounds due to fragmentation of bone or the bullet. Generally the exit wound is larger and has ragged edges. Wound Ballistics: Medium and High velocity wounds

25 Entrance and Exit Wounds

26 The wound consists of three parts: Internal wound: Medium-velocity bullets inflict damage primarily by damaging tissue that the bullet contacts; High- velocity bullets inflict damage by tissue contact and transfer of kinetic energy (the shock wave producing a temporary cavity) to surrounding tissues Wound Ballistics: Medium and High velocity wounds

27 Mechanism of Injury: Penetrating Trauma

28 Gunshot wound trauma injuries

29 Head: The skull is a closed space, thus presenting some unique situations: The shock wave has no place to go therefore the brain tissue can be compressed. If the forces are strong enough the skull may explode from the inside out. A medium velocity bullet may follow the curvature of the interior of the skull. This path can produce significant damage Penetrating Trauma Injuries

30 Punctures/Penetrations (Gunshot wounds)

31

32 Thorax: Three major groups of structures inside the thoracic cavity must be considered in evaluating a penetrating injury to the chest: Lungs: Less dense tissue so injuries are generally from the bullet tract and less so from a shock wave. Serious injuries include a pneumothroax or hemothorax Penetrating Trauma Injuries

33 Thorax: Vasular: Blood and muscle is more dense than lung tissue, therefore it is more susceptible to shock waves in addition to the bullet track. Injuries include damage to the aorta and the superior vena cava as well as injury to the heart muscle. Penetrating Trauma Injuries

34 Thorax: Gastrointestinal: The esophagus is located in the thorax and may be injured by the bullet track Injuries include damage to the esophagus as well as spilling any contents into the thoracic cavity which can lead to infection. Penetrating Trauma Injuries

35 Punctures/Penetrations (Gunshot wounds)

36 Abdomen: The abdomen contains structures of three types: Air filled, solid and bony. Gastrointestinal: The majority of the GI system is located in the abdomen. Most of the GI tract structures are considered to be air filled. Injuries include damage to the GI system structures as well as spilling any contents into the abdominal cavity which can lead to infection. Penetrating Trauma Injuries

37 Abdomen: Solid organs: The solid organ of the abdomen are very susceptible to direct injury as well as injury from the shock wave. Injuries include direct and shock wave damage to all of the solid organs such as the liver, spleen, pancreas, and the kidneys in the retroperitoneal space. Let’s not forget about the bladder, uterus, ovaries, gall bladder, and major blood vessels such as the vena cava and the aorta. Penetrating Trauma Injuries

38 Abdomen: Bones: The pelvis is a very vascular organ. Fracture of the pelvic due to a gunshot wound can lead to major blood loss Injuries are generally limited to direct bullet track damage. The bone fragments may become secondary missiles and cause additional damage. Penetrating Trauma Injuries

39 The ultimate in fragmentation is created by shotgun wounds Shotgun Wounds

40 Muscles, peripheral nerves and blood vessels, connective tissue, skin and bones: All of these tissues may suffer direct injury or shock wave injuries. Injuries may include: tissue loss, bleeding, and loss of function, Penetrating Trauma Injuries

41 Open Wound

42 Rapid Trauma Assessment

43 Head Neck Chest Abdomen Pelvis Extremities Posterior

44 Inspect and Palpate for DCAP-BTLS ======== DCAPDCAP Deformities Contusions Abrasions Punctures/ Penetrations ======== BTLSBTLS Burns Tenderness Lacerations Swelling

45 Assess baseline vital signs. Obtain SAMPLE history. Consider requesting ALS. Reconsider transport decision. Significant Mechanism of Injury

46 SAMPLE History S=Signs and symptoms A=Allergies M=Medications P=Pertinent past history L=Last oral intake E=Events leading to injury or illness

47 If No Significant Mechanism of Injury Reconsider mechanism of injury. Determine chief complaint. Perform focused physical exam based on: Chief complaint Mechanism of injury

48 SECONDARY SURVEY

49 The Detailed Physical Exam Assess areas examined in rapid trauma assessment plus: Face Ears Eyes Nose Mouth Head Neck Chest Abdomen Pelvis Extremities Posterior

50 Examine slower than during rapid trauma assessment. Often done during transport. Reassess vital signs. The Detailed Physical Exam

51 Bleeding and Shock

52 External Bleeding

53 Severity of Blood Loss Determined by: General impression of blood loss Signs or symptoms of hypoperfusion

54 Sudden loss of... One liter of blood in an adult Half a liter of blood in a child 100-200cc of blood in an infant...is serious!

55 Uncontrolled bleeding or significant blood loss leads to shock (hypoperfusion) and possibly death! Do not wait for signs and symptoms to appear before beginning treatment! Blood Loss

56 Internal Bleeding

57 Signs & Symptoms of Internal Bleeding Significant MOI Pain, tenderness, deformity, swelling, discoloration Bleeding from the mouth, rectum, or vagina Tender, rigid, or distended abdomen

58 Maintain airway; administer oxygen. Control external bleeding.

59 Elevate lower extremities 8-12 inches. Prevent loss of body heat.
