Q

Excited delirium

A

is a controversial condition that arises typically in male subjects with a history of mental illness and/or acute or chronic drug abuse, particularly stimulant drugs. Some groups claim that this condition was “invented” to cover up the use of excessive force by law enforcement the American College of Emergency Physicians has accepted excited delirium as a unique syndrome, despite the World Health Organization, and the American Psychiatric Association failing to acknowledge it as a medical or psychiatric diagnosis.

Q

Paramedics should consider the following when dealing with a patient displaying the signs of excited delirium:

A

• Are we safe? • Consider the need for physical restraint and sedation (ALS skill). Physical restraint is something that should be conducted with appropriate resources and preferably the assistance of law enforcement. • Is the patient safe? • Arms, legs, and body securely affixed to the cot? • If the choice to restrain is made are we restraining the patient in such a way to allow for breathing and airway control? • If ALS sedates the patient are we in a position to assist with breathing and provide supplemental oxygen? • What else could be going on? • remember that we need to rule but all other conditions before deciding on one specifically.

Q

pathophysiology of Type 1 diabetics (insulin dependant)

A

Cell takes glucose into cell to create energy but insulin dependent diabetics’ cells don’t let glucose in so it uses fat as energy which is converted to fatty acids The fatty acids create a lot of ketones as by products Ketones convert to hydrogen ions, CO2 and heat This can lead to diabetic ketoacidosis

Q

Diabetic Ketoacidosis

A

Life threatening Occurs when certain acids accumulate in the body DKA occurs when the cells experience famine Because the cells are lacking glucose to convert to energy they begin to use other sources for energy The metabolism of fat causes the build up of acids and ketones The body also experiences a loss of water and electrolytes due to high levels of glucose in the blood

79
Q

Seizures

A

Sudden erratic firing of neurons Abnormal electrical discharge from the brain Signs and symptoms depends on the part of brain Causes- we don’t really know why idiopathic

80
Q

Generalized seizure

A

Affect large portion of the brain Includes tonic-clonic and absence types Tonic clonic: full body movement

81
Q

Steps of a tonic clonic

A

Aura: pt experiences a sensation Loss of cx: pt loses consciousness Tonic: body wide rigidity Hypertonic: arched back and rigidity Clonic: rhythm contraction of major muscle groups Post seizure: muscles relax Postictal: “rest” period for the brain may last minutes to hours Breathing will sound abnormal

82
Q

Absence Seizure

A

Absence spells (thousand-mile stare) Most common in children Short duration

83
Q

Partial seizures

A

affecting a limited portion of the brain

84
Q

Complex partial Simple partial (Jacksonian March)

A

Complex partial -Subtle loss of cx -Head or eyes make small movement Simple partial (Jacksonian March) -Tonic clonic activity to one body part -No aura or loss of cx

85
Q

Febrile seizures

A

Caused by high body temp Neurons in the brain are highly sensitive to temperature changes As the temp rises the effects on the neurons become more profound and if allowed to progress may lead to a seizure Simple and short- if they’re long or hard to stop the seizure is probably in conjunction with an underlying problem Very short to no postictal period

86
Q

Status epilepticus

A

A seizure that last for longer than 4-5mins OR consecutive seizures that occur without return of cx between seizure episodes True medical emergency!!

87
Q

Convulsive Disorders ASSESSMENT

A

Stay calm Communication Questions –Where and what was the patient doing before the seizure –How long did it last What did it look like –Does the pt have a history of seizures ——Are they like this one ——Any medication changes -Pt have a fever -Was the pt apneic, cyanotic or vomiting -Incontinence? -SAMPLE -v/s

88
Q

Convulsive Disorders- TREATMENT

A

OPA/NPA Positioning Supplemental oxygen Don’t let tubing get tangled Suction ready Rule out treatable causes Temp BGL Pupils- drugs IV- med route Cardiac monitor ALS

89
Q

Sinus headache

A

pain is usually behind the forehead and/or cheekbones Caused by inflammation or infection of sinus cavities in the face Increase with movement Usually worse when person first wakes up Can be flu symptoms

90
Q

Cluster headache

A

pain is in and around one eye Vascular type Often start in face Last 30-45 mins Pain radiates to entire side of face Can occur multiple times a day and then just go away

91
Q

Tension headache

A

Pain is like a hand squeezing the head Cause from stress Tense muscles Most common

92
Q

Migraine headache

A

pain, nausea and visual changes are typical of classic form Some patients experience aura before Pain unilateral and focused Pain will change or spread over time Throbbing, pounding or pulsing in nature Can last hours to days

93
Q

cluster headache Treatment

A

Symptomatically Supportive and comfort

94
Q

Bell’s Palsy

A

Temporary paralysis of 7th cranial nerve 7th cranial nerve controls facial movement Takes weeks to months to go back to normal

95
Q

Bell’s Palsy Treatment

A

Symptomatically Supportive and comfort

96
Q

Trigeminal neuralgia

A

The normal function of facial blood vessels produces severe pain As the blood vessel change in diameter to meet the needs of surrounding tissue their positions can irritate the trigeminal nerve This nerve is responsible for receiving signals related to pain, temperature and pressure on the face

97
Q

Cerebrovascular Accidents (CVA)2 types:

A

Ischemic stroke: blockage -Thrombotic -Embolic Hemorrhagic: ruptured artery/vesel -Loss of blood flow to some part of the brain -Temporary or permanent damage from lack of oxygen -Signs and symptoms depends on artery and area of brain

98
Q

Ischemic CVA

A

75% most common Caused when a blood vessel becomes occluded and blocked blood flow Only the tissue on the blockage will be affected Eventually will plateau Severity depends on part of brain

99
Q

Hemorrhagic

A

Bleeding that has interfered with the brains ability to function 20% less common More devastating because it worsens overtime Can start to see signs and symptoms of ICP Pressure on them medulla oblagata results in Cushing’s reflex Common complaint “worst headache they’ve ever experienced”

100
Q

Transient ischemic attack (min stroke)

A

Temporary artery blockage s/s resolve within 24hrs warning sign of a larger CVA to come present similar to CVA except s/s resolve encourage transport for further assessment

101
Q

signs and symptoms of CVA/ TIA

A

slurred speech unilateral weakness or paralysis facial droop arm drift headaches decreased LOC seizures N/V
