common condition causing hypothermia

Cold-water immersion acute illness (e.g., sepsis) Traumatic injury Shock states Immobilization Cold weather (especially for people who are homeless or work outdoors) Older age Use of medications (e.g., phenothiazines, barbiturates) Inappropriate alcohol and substance use Undernutrition Hypothyroidism Inadequate clothing or shelter (e.g., the homeless population)

snake bite prevention

Do not keep venomous snakes or constricting snakes as pets. Be extremely careful in locations where snakes may hide, such as tall grass, rock piles, ledges and crevices, woodpiles, brush, boxes, and cabinets. Snakes are most active on warm nights. Wear protective attire such as boots, heavy pants, and leather gloves. When walking or hiking, use a walking stick or trekking poles. Inspect suspicious areas before placing hands and feet in them. Do not harass any snakes you may encounter. Striking distance can be up to two thirds the length of the snake. Even young snakes pose a threat; they are capable of envenomation from birth. Be aware that newly dead or decapitated snakes can inflict a bite for up to an hour after death because of persistence of the bite reflex. Do not transport the snake with the victim to the medical facility for identification purposes; instead, take a digital photo of the snake at a safe distance if possible.

A: airway

Establish a patent airway by positioning, suctioning, and administering oxygen as needed Protect the cervical spine by maintaining alignment; use a jaw-thrust maneuver if there is a risk for spinal injury If the Glasgow Coma Scale (GCS) score is 8 or lower or the patient is at risk for airway compromise, prepare for endotracheal intubation and mechanical ventilation.

D: disability

Evaluate the patient's level of consciousness (LOC) using the GCS or APVU Re-evaluate the patient's LOC frequently.

Hazardous Materials training undergone by ED physicians, providers, and nursing staff learn how to recognize patterns of illness in patients who present for tx that potentially indicate biologic terrorism agents such as anthrax or smallpox

advanced cardiac life support (ACLS)

Invasive airway-management skills, pharmacology, and electrical therapies; special resuscitation situations

C: circulation

Monitor vital signs, especially blood pressure and pulse Maintain vascular access with a large-bore catheter Use direct pressure for external bleeding; anticipate need for a tourniquet for severe, uncontrollable extremity hemorrhage, wound packing, and/or use of a hemostatic dressing.

Pediatric Advanced Life Support (PALS)

Neonatal and pediatric resuscitation

Basic Life Support (BLS)

Noninvasive assessment and management skills for airway maintenance and cardiopulmonary resuscitation (CPR)

lightening strike prevention

Observe weather forecasts when planning to be outside. a lightning strike is imminent if your hair stands on end, you see a blue halo around objects, and you hear high-pitched or crackling noises. If you cannot move away from the area immediately, crouch on the balls of your feet and tuck your head down to minimize the target size; do not lie on the ground or make contact with your hands to the ground. Seek shelter when you hear thunder. Go inside the nearest building or an enclosed vehicle. Avoid isolated sheds and cave entrances. Do not stand under an isolated tall tree or structure (e.g., ski lift, flagpole, boat mast, power line) in an open area such as a field, ridge, or hilltop; lightning tends to strike high points. Instead, seek a low area under a thick growth of saplings or small trees. Leave water immediately (including an indoor shower or bathtub) and move away from any open bodies of water. Avoid metal objects such as chairs or bleachers; put down tools, fishing rods, garden equipment, golf clubs, and umbrellas; stand clear of fences, exposed pipes, motorcycles, bicycles, tractors, and golf carts. if inside a car with a solid hood, close the windows and stay inside. If in a convertible, leave the car at least 49 yards (45 meters) away and huddle on the ground. If inside a tent, stay away from the metal tent poles and wet fabric of the tent walls. If you are caught out in the open and cannot seek shelter, attempt to move to lower ground such as a ravine or valley; stay away from any tall trees or objects that could result in a lightning strike splashing over to you; place insulating material between you and the ground (e.g., sleeping pad, rain parka, life jacket). If inside a building, stay away from open doors, windows, fireplaces, metal fixtures, and plumbing. Turn off electrical equipment, including computers, televisions, and stereos to avoid damage. stay off land-line telephones. Lightning can enter through the telephone line and produce head and neck trauma, including cataracts and tympanic membrane disruption. Death can result. Avoid use of cellular phones, which can transmit loud static that can cause acoustic damage.

Arthropod Bite/Sting Prevention

Wear protective clothing, including gloves and shoes, when working in areas known to harbor venomous arthropods such as spiders, scorpions, bees, and wasps. Cover garbage cans. Bees and wasps are attracted to uncovered garbage. Use screens in windows and doors to prevent flying insects from entering buildings. Inspect clothing, shoes, and gear for insects before putting on these items. Shake out clothing and gear that have been on the ground to prevent arthropod "stowaways" and inadvertent bites and stings. Consult an exterminator to control arthropod populations in and around the home. Eliminating insects that are part of the arthropod's food source may also limit their presence. Identify nesting areas such as yard debris and rock piles; remove them whenever possible. Do not place unprotected hands where the eyes cannot see. Avoid handling insects and arthropods or keeping them as "pets." Do not swat insects, wasps, and Africanized bees because they can send chemical signals that alert others to attack. Carry a prescription epinephrine autoinjector and antihistamines if known to be allergic to bee and wasp stings. Ensure that at least one significant other person is also able to use the autoinjector.

patients who are most medically stable may be discharged early, including those who:

Were admitted for observation and are not bedridden Are having diagnostic evaluations and are not bedridden Are soon scheduled to be discharged or could be cared for at home with support from family or home health care services Have had no critical change in condition for the past 3 days Could be cared for in another health care facility such as rehabilitation or long-term care

moderate hypothermia interventions

active external and core (internal) rewarming methods applying external heat with heating blankets can promote core temperature "after-drop" by producing peripheral vasodilation After-drop is the continued decrease in core body temperature after the victim is removed from the cold environment; it is caused by the return of cold blood from the periphery to the central circulation. Therefore the patient's trunk should be actively rewarmed before the extremities core rewarming methods: administration of warm IV fluids; heated oxygen or inspired gas to prevent further heat loss via the respiratory tract; and heated peritoneal, pleural, gastric, or bladder lavage.

emergency medicine physician

receive specialized education and training in emergency patient management

frostbite first aid/prehospital care

recognition of frostbite is essential to early, effective intervention and prevention of further damage to tissue integrity ask a significant other to frequently observe for early signs of frostbite such as a white, waxy appearance to exposed skin, especially on the nose, cheeks, and ears, is an effective strategy to identify the problem before it worsens in people with dark skin, skin becomes paler, waxy, and somewhat gray. In this case the best remedy is to have the person seek shelter from the wind and cold and attend to the affected body part superficial frostbite is easily managed using body heat to warm the affected area. teach patients to place their warm hands over the affected areas on their face or to place cold hands under the arms.

signs of human trafficking

recurrent STIs pregnancy tests and abortions physical signs: headaches, dizziness, back pain, missing patches of hair, burns, bruises, vaginal or rectal trauma, jaw problems, head injuries unusual tattooing or branding marks - signify ownership stress, paranoia, fear, suicidal ideation, depression, anxiety, shame, and self-loathing unable to identify home address, deny having finances, and defer to the controlling presence of an individual who has accompanied them to the ED

blunt trauma

results from impact forces such as those sustained in a MVC, fall or assault with fists, kicks, or baseball bat blast effect from exploding bomb

Impact of Event Scale (IES-R)

self-administered questionnaire that is used to detect PTSD or ASD score greater than 33 (possible 88) is indicative of probable PTSD high scores indicate a need for further eval and counseling: refer to mental health specialist

human trafficking

sexual exploitation - type of modern day slavery in which the victim is forced or coerced to provide sex to others in exchange for money or valuables that are given to the trafficker

mild hypothermia first aid/prehospital interventions

shelter from cold environment remove all wet clothing undergo passive or active rewarming non-complicated- drink warm high-carb liquids w/o alcohol and caffeine

mild hypothermia symptoms

shivering dysarthria --- slurred speech decreased muscle coordination impaired cognition diuresis

personal emergency preparedness plan

should outline the preplanned specific arrangements that are to be made for child care, pet care, and older adult care if the need arises, especially if the event prevents returning home for an extended period assemble a go bag, arrange for child and pet care, note who will be called when the plan is activated, note where a nurse is expected to report, collect names, addresses, and telephone numbers to be used if a crisis occurs

hand-off communication components

situation - reason for being in the ED and admitting diagnosis Pertinent medical HX, including implantable devices, and any hx of organ transplant assessment and diagnostic findings, particularly critical results transmission-based precautions and safety concerns (fall risk, allergies) interventions provided in the ED and response to those interventions

sexual assault nurse examiners (SANEs) or sexual assault forensic examiners (SAFEs)

specialize in helping victims of sexual assault

heat exhaustion interventions

stop physical activity immediately and move to a cool place cooling measures: cold pack on neck, chest, abdomen, and groin soak individual in cool water or fan whole spraying water on skin remove constrictive clothing provide sports drinks or oral rehydration-therapy - drinking plain water can worsen sodium deficit DO NOT GIVE SALT TABLETS if s/s persists call ambulance

exertional heat stroke

sudden onset and is often the result of strenuous physical activity (esp. when wearing too heavy clothing) in hot, humid conditions

drowning prevention

swim and are in or around water. do not swim alone. test the water depth before diving in head first; never dive into shallow water. avoid alcoholic beverages and substance use when swimming and boating and while in proximity to water. ensure that water rescue equipment such as life jackets, flotation devices, and rope is immediately available when around water.

heat exhaustion

syndrome resulting primarily from dehydration caused by heavy perspiration and inadequate fluid and electrolyte intake during heat exposure over hours to days if untreated can lead to heat stroke

primary survey and resuscitation

the ABCDEs of emergency care; once the problem(s) is identified, resuscitative action should begin immediately

grade 1 frostbite

the least severe type of frostbite, involves hyperemia (increased blood flow) of the involved area and edema formation.

grade 4 frostbite

the most severe form, there are blisters over the carpal or tarsal (instead of just the digit) the part is numb, cold, and bloodless. full-thickness necrosis extends into the muscle and bone at this stage, gangrene develops, which may require amputation of the affected part. Of note, except for frostnip, other degrees of frostbite may all have the same general appearance while the body part is frozen; the differentiating features of each degree of frostbite only become apparent after the part is thawed. Gangrene may evolve over days to weeks after injury.

frostnip

type of superficial cold injury that may produce pain, numbness, and pallor or a waxy appearance of the affected area but is easily relieved by applying warmth it does not cause impaired tissue integrity typically develops on areas such as the face, nose, finger, or toes. Untreated, it is a precursor to more severe forms of frostbite.

preventing ASD and PTSD following a mass casualty event

use available counseling encourage and support co-workers monitor each other's stress levels and performance take breaks when needed talk about feelings with staff and managers drink plenty of water and eat health snacks for energy keep in touch with family, friends, and significant others do not work more than 12 hours per day

severe hypothermia interventions

use extracorporeal rewarming methods such as cardiopulmonary bypass or hemodialysis cardiopulmonary bypass, which requires specialized personnel and resources, is the fastest core rewarming technique. However, this device is not available in all hospitals monitor for early signs of complications that can occur after rewarming such as fluid, electrolyte, and metabolic abnormalities; acute respiratory distress syndrome (ARDS); acute renal failure; and pneumonia.
