11 Insert Fig Anatomy and Physiology of the Nervous System (1 of 2)
12 Anatomy and Physiology of the Nervous System (2 of 2) Divided into the central nervous system and the peripheral nervous system –Central nervous system consists of parts of the nervous system that are covered and protected by bones. –Peripheral nervous system is made up of cables of nerve fibers that link the nerve cells to the body’s organs.
13 Central Nervous System (1 of 2)
14 Central Nervous System (2 of 2) Composed of the brain and spinal cord. The brain controls the body. –Divided into three parts Cerebrum Cerebellum Brain stem The spinal cord carries messages between the brain and the body.
17 Peripheral Nervous System (2 of 3) Anatomic parts –31 pairs of spinal nerves Conduct sensory impulses from the skin and other organs to the spinal cord Conduct motor impulses from the spinal cord to the muscles –12 pairs of cranial nerves Transmit sensations to and from the brain
18 Peripheral Nervous System (3 of 3) Types of peripheral nerves –Sensory nerves carry information from the body to the brain via the spinal cord. –Motor nerves carry information from the CNS to the muscles. –Connecting nerves connect sensory and motor nerves with short fibers.
19 How the Nervous System Works Controls the body’s activities Voluntary activities: somatic nervous system Involuntary activities: autonomic nervous system Sympathetic nervous system: fight-or-flight Parasympathetic nervous system: relax
20 Anatomy and Physiology of the Skeletal System The skull has two layers of bone. –Divided into two large structures: cranium and face The spinal column supports the body. –Has 33 bones or vertebrae –Divided into five sections: cervical, thoracic, lumbar, sacral, and coccygeal
21 Spinal Column
22 Injuries of the Spine Compression Overextension Flexion Rotation Lateral bending Fractures and neurologic defects Distraction
23 Assessment of Spinal Injuries (1 of 3) Mechanisms of Injury –Motor vehicle crashes –Pedestrian-motor vehicle collisions –Falls –Blunt or penetrating trauma –Motorcycle crashes –Hangings –Driving accidents –Recreational accidents
24 Assessment of Spinal Injuries (2 of 3) Questions to ask –Does your neck or back hurt? –What happened? –Where does it hurt? –Can you move your hands and feet? –Can you feel me touching your fingers? Your toes?
25 Assessment of Spinal Injuries (3 of 3) Signs and symptoms –Pain or tenderness of spine –Deformity of spine –Tingling in the extremities –Loss of sensation or paralysis –Incontinence –Injuries to the head
26 Emergency Medical Care Follow BSI precautions. Manage the airway. –Perform the jaw-thrust maneuver to open the airway. –Consider inserting an oropharyngeal airway. –Administer oxygen. Stabilize the cervical spine.
27 Stabilization of the Cervical Spine (1 of 2) Hold head firmly with both hands. Support the lower jaw. Move to eyes-forward position. Maintain the position until patient is secured to a backboard.
28 Stabilization of the Cervical Spine (2 of 2) Do not force the head into a neutral, in-line position if any of the following exist: –Muscle spasms –Pain increases with movement –Numbness, tingling, or weakness –Compromised airway or breathing
29 Preparation for Transport: Supine Patients (1 of 2) Maintain in-line stabilization. Assess pulse, motor, and sensory function. Apply appropriately sized cervical collar. Have the other team members position the immobilization device.
30 Preparation for Transport: Supine Patients (2 of 2) Log roll patient. Ensure that patient is centered on board. Secure patient to backboard. Reassess pulse, motor, and sensory function in each extremity, and continue to do so periodically.
31 Preparation for Transport: Sitting Patients Maintain manual in-line stabilization. Assess pulse, motor, and sensory function. Apply a cervical collar. Place a short board behind patient. Position device around patient. Turn patient and lower to long backboard. Secure short and long backboards together. Reassess the pulse, motor, and sensory function.
32 Preparation for Transport: Standing Patients Stabilize the head and neck and apply a cervical collar. Position board behind patient. Carefully lower the patient to the ground.
33 Head Injuries Scalp lacerations Skull fractures Brain injuries Medical conditions Complications of head injuries
34 Scalp Lacerations Scalp has a rich blood supply. There may be more serious, deeper injuries. Fold skin flaps back down onto scalp. Control bleeding by direct pressure.
35 Skull Fracture Indicates significant force Signs –Obvious deformity –Visible crack in the skull –Raccoon eyes –Battle’s sign
36 Brain Injuries (1 of 3) Concussion –Temporary loss or alteration in brain function –May result in unconsciousness, confusion, or amnesia
37 Brain Injuries (2 of 3) Contusion –Brain can sustain bruise when skull is struck. –There will be bleeding and swelling. –Bleeding will increase the pressure within the skull.
38 Brain Injuries (3 of 3) Intracranial bleeding –Laceration or rupture of blood vessel in brain Subdural Intracerebral Epidural
39 Other Brain Injuries Brain injuries are not always caused by trauma. Medical conditions may cause spontaneous bleeding in the brain. Signs and symptoms of nontraumatic injuries are the same as those of traumatic injuries. –There is no mechanism of injury.
40 Complications of Head Injury Cerebral edema Convulsions and seizures Vomiting Leakage of cerebrospinal fluid
41 Assessing Head Injuries Common causes –Motor vehicle crashes –Direct blows –Falls from heights –Assault –Sports Injuries Evaluate and monitor level of consciousness
42 Types of Head Injuries Closed –Associated with trauma Open –Caused by penetrating object
43 Signs and Symptoms (1 of 3) Lacerations, contusions, hematomas to scalp Soft areas or depression upon palpation Visible skull fractures or deformities Ecchymosis around eyes or behind the ear Clear or pink CSF leakage
44 Signs and Symptoms (2 of 3) Failure of pupils to respond to light Unequal pupils Loss of sensation and/or motor function Period of unconsciousness Amnesia Seizures
45 Signs and Symptoms (3 of 3) Numbness or tingling in the extremities Irregular respirations Dizziness Visual complaints Combative or abnormal behavior Nausea or vomiting
46 Level of Consciousness Change in level of consciousness is the single most important observation. Use the AVPU scale or Glasgow Coma Scale (depending on local protocols). Reassess –Every 15 minutes if patient is stable. –Every 5 minutes if patient is unstable.
47 Changes in Pupil Size Unequal pupil size may indicate increased pressure on one side of the brain.
48 Emergency Medical Care Establish an adequate airway. Control bleeding and provide adequate circulation. Start large bore IV. Assess the patient’s baseline level of consciousness.
49 Managing the Airway Establish a patent airway. Perform jaw-thrust maneuver to open airway. Apply cervical collar. Suction as needed. Assess ventilatory status. Provide supplemental oxygen. Check oxygen saturation.
50 Circulation Start CPR if patient is in full arrest. Control bleeding. Apply cervical collar. Treat for shock. Consider IV bolus.
51 Immobilization Devices: Cervical Collars One EMT-I provides continuous manual in-line support of the head. Measure the proper size of the collar. Place the chin support snugly under the chin. Wrap the collar around the neck. Ensure that the collar fits.
52 Immobilization Devices: Short Backboards Short backboards –Used on patients found in a sitting position
53 Immobilization Devices: Long Backboards Long backboards –Provide full-body immobilization
54 Helmet Removal (1 of 6) Is the airway clear and is the patient breathing adequately? Can airway be maintained and ventilations assisted with helmet in place? How well does the helmet fit? Can the patient’s head move within the helmet? Can the spine be immobilized in a neutral position with the helmet on?
55 Helmet Removal (2 of 6) A helmet that fits well prevents the head from moving and should be left on, as long as the following conditions apply: –There are no impending airway or breathing problems. –It does not interfere with assessment and treatment of the airway. –You can properly immobilize the spine.
56 Helmet Removal (3 of 6) Prevent head movement.
57 Helmet Removal (4 of 6) Slide helmet off while partner supports head.
58 Helmet Removal (5 of 6) –Partner supports head. –Remove helmet. –Apply cervical collar. –Pad shoulders if necessary. –Kneel at patient’s head. –Open the face shield. –Stabilize the helmet. –Loosen the strap. –Gently slip halfway off. Preferred method
59 Helmet Removal (6 of 6) Alternative method –Used with football helmets. –Remove chin strap. –Remove face mask. –Remove pads. –Continue in the same manner as the preferred method.
60 Pediatric Needs Immobilize a child in the car seat, if possible. Children may need extra padding to maintain immobilization.
