BURNS

• Burn injuries caused by extreme heat sources but may also result from exposure to cold, chemicals, electricity, or radiation.

Incidence

• Approximately 1/4th of cases are below 10 yrs of age.

• About 65% of burnt children are <5yrs of age.• >80% of burn accidents occurs in the child’s

own home.• Scalds from hot liquids constitute maximum

numbers than others(flame, electrical, chemical).

• Incidence increased in diwali festival & winter season.

ETIOLOGY• Scald injury from moist heat : kitchen or

bathroom – (water at 68oC / 156oF can cause 3rd degree burn in one second.

• Flame injury : faulty

electrical wiring, cigarettes,

kerosene stove, gas stove,

cloths catches fire, crackers.

• Electrical injury : inserting

conductive objects into electrical outlets, bite or suck in electrical cords.

Causes contd..

• Chemical injury and contact injury : handling or ingestion of caustic household agents.

• Radiation injury : overexposure to ultra violet rays from the sun

Radiation burn

The effect of burns …• Circulating plasma volume loss →decrese cardiac output (by 36

hrs. of burn).

• Hypovolemia → diminished renal perfusion → reduced GFR→renal failure.

• Water, electrolyte, albumin & protein extravate into interstitial & intracellular compartments, forming edema.

• Decrease perfusion in peripheral tissue, metabolic acidosis, hypotension.

• Polycythemia due to hemoconcentration

• Increase blood viscosity leading to slugging in the vasculature.

• Acute gastric dilation→abdominal distension→ regurgitation; decrease blood supply→decrease motility→malabsorption; gastric ulceration.

Clinical manifestations• Body surface area burnt

• Shock (pallor, cyanosis, poor muscle tone, rapid pulse, hypotension, subnormal temp.)

• Inhalation cases – inflammation /edema of airway → obstruction of airway ( dyspnea, tachypnea, hoarseness, stridor, chest retractions, nasal flaring, restlessness, cough, drooling)

• Pulm. Edema, spasm leads to severe airway obstruction, bronchiolitis

• Toxemia- fever, vomiting, ededma, oliguria, tachycardia, glycosuria, unconsciousness

Classification According to depth of burn injury :• Superficial (partial thickness) –

- Superficial partial thickness

- Superficial deep thickness

• Full thickness

According to event of burn injury :• 1st degree

• 2nd degree

• 3rd degree

According to severity :• Minor

• Major

Estimation of depth of burn injury

• First degree : affecting the epidermal layer is characterized by erythema due to vascular response, edema occurs in the basal layer irritating the nerve ending & causing discomfort.

• Second degree : subdivided into superficial partial & deep partial thickness burns.

-- In superficial partial thickness – the surface may be covered with blisters, the skin beneath it is glistening bright pink & red, sensitive to touch, temp. & airflow.

-- Deep partial thickness –destroys entire thickness of epidermis.

• Third degree : full thickness burns involves all epidermis & dermis. The burnt skin is hard & dry, tan or fawn colored. Higher morbidity.

4th degree

Classification --• Minor – 1st degree, 2nd degree of <10% of

body surface area, 3rd degree <2% of BSA.

• Moderate – 2nd degree with 10-25% of BSA, 3rd degree <10% of BSA (except face, hand & feet).

• Major – 2nd degree >25% of BSA or 3rd degree over face, hand or feet or/ > 10% of BSA.

Estimation of burn area

• Rule of hand : one hand surface(child’s own hand) with closed fingers amounts to 1% of body surface area.

• Rule of nines : first described by Pulaski & Tennison & popularized by Wallace; applicable only to children >10yrs of age & adults.

*Leg= 13.5 each leg

*Head front

& back=18%

Adult & *children

HEMORRHAGE

• Hemorrhage is a condition in which a person bleeds too much and can not stop the flow of blood.

CLASSIFICATION

• IT IS CLASSIFIED ACCORDING TO APPEARANCE AS:

1. EARLY ONSET

2. CLASSIC ONSET &

3. LATE ONSET

EARLY

• Sign and symptoms of hemorrhagic disease typically appear within hours of birth.

SIGN AND SYMPTOMS:

• Oozing from the umbilicus or circumcision site

• Bloody or black stool

• Hematuria

• Epistaxis or bleeding from punctures.

CLASSIC

• It occurs usually at 1-7 days after birth

• Sign and symptoms are same as that of early onset

DIAGNOSTIC MEASURES:

1. Prolonged prothrombin time

2. Partial thromboplastin time

3. Fibrinogen level

4. Platelet count

LATE ONSET• It appears at approximately 2 -12 weeks of

age . This form occurs in totally or predominantly 2 to 12 weeks of age

CLINICAL MANIFESTATION:

• Evidence of intracranial hemorrhage

• Deep echymoses and

• Bleeding from the gastrointestinal tract, mucous membranes, skin punctures or surgical incision.

ASSESSMENT

• The prothrombin time ,blood coagulation time are prolonged.

• Levels of prothrombin (II) and factors (VIII),(IX) and(X)are markedly decreased.

• Haematemesis, epistaxis, malena

NURSING MANAGEMENT• Careful administration of vitamin-k into the

vastus lateralis muscle or ventrogluteal injection sites.

• Observe for signs of disorder.

• Notify the physician for appropriate diagnosis and treatment.

• Breast feeding mother are encouraged to increase their intake of food containing vitamin k eg. green leafy vegetables.

• Protection of child

• Education to parents

FOREIGN BODY INGESTION AND ASPIRATION

• Common in infants and children between the age group of 6 months and 3 years.

• Boys are twice as

likely as girl to

aspirate.

• Coins, nuts, metals,

bones, vegetables

and plastic objects

WHY …..• Small children are curious & innocent for

inserting various object into their orifices like mouth, nose, ears, anus & vagina.

• Severity is determined by the location, type of object aspirated, extent of obstruction.

SIGN AND SYMPTOMS

❑Dysphagia, choaking, gagging,

coughing

❑ Inability to speak

❑ Poor feeding

❑ Vomiting

❑ Neck or throat pain

❑ Refusal to eating or drinking

❑Cyanosis, dyspnea, stridor, wheezing

❑Unconsciousness, death

Treatment • Laryngoscopic or bronchoscopic removal of

foreign body.

• If the object is lodged in the larynx, tracheostomy may be necessary.

• After removal of foreign body, child is placed in a high humidity atmosphere.

• Antibiotics to prevent secondary infection.

• Observation.

NURSING MANAGEMENT

• Recognize the sign of aspiration →immediate removal.

• Foreign bodies should not be allowed to remain in the esophagus more than 24 hours

• Prepare the patient for flexible endoscopy if prescribed.

• Teach family and parents regarding prevention of foreign body ingestion.

Contd……

• Teach children not to put anything in their mouth except food.

• Promote safe environment to infant and toddlers.

• Teach to immediately seek treatment if a child swallows an object.

• Prevent secondary infection

Prevention • Keeping small objects such as toys with

movable parts, safety pins, small candies, nuts, marbles out of children.

• Adult should not do such danger activities which children can imitate.

• Supervised play for small children.

• Teaching parents regd. safety & security

• Constant supervision

• (? Effect of mass media)

POISONING

• Common medical emergency in children.

• Under 5 yrs. of age all poisoning are accidental.

• Nearly 75% of all poisoning episodes involve ingestion of substance which are nontoxic or have mild toxicity.

• Poisoning is defined as a morbid condition caused by the ingestion of a toxic substance.

POISON!

• A poison is any substance that when ingested, inhaled or absorbed even in relatively less amounts can cause damage to a structure or disturbance of body function by its chemical action.

Definitions

• A poison exposure is the ingestion of or contact with a substance that can producetoxic effects.

• A poisoning is a poison exposure that results in bodily harm.

• Poison exposures can occur by accident without intent, and these exposures are defined as unintentional poisonings. In some situations, poison exposures are the result of a conscious, willful decision; these cases are defined as intentional poisonings.

Poisoning agents

Shannon M. N Engl J Med 2000;342:186-191

Agents Most Commonly Ingested by Children Less Than Six Years of Age, 1995 to 1998

54

Epidemiology: “the numbers”

• Nearly 90% of exposures occurring at home

• During pre-adolescence : slight high in male

– This reverses in ages 13-19 with females accounting for 55 percent of poisonings

• Children, especially those under age 6, are more likely to have unintentional poisonings than older children and adults (Ref.- Litovitz 2001).

• Adolescents are also at risk for poisonings, both intentional and unintentional. About half of all poisonings among teens are classified as suicide attempts (Ref.- Litovitz 2001).

55

Common clinical manifestations

• GI Disturbances : nausea, vomiting, anorexia, abdominal pain, diarrhea, discomfort.

• Respiratory & Circulatory : possible unexplained cyanosis, shock, collapse.

• CNS : lethargy, sudden loss of consciousness, convulsion, dizziness, coma.

• Approach begins with initial

evaluation and stabilization (ABCDE)!!!!!!!

• This is followed by a thorough approach

to identify the agent(s) involved

• Often, the suspected toxic agent will determine the priorities of management

• Supportive cares, prevention of poison absorption, antidotes, enhanced elimination may subsequently be involved

Approaching the Poisoned Child

Management for poisoning & overdose…

• Evaluation of child status in terms of immediate , potential or no danger.

• Weight & age to estimate level of potential toxicity.

• Time of ingestion

• Type, amount & route of exposure

Poisoning in ChildrenABC’s of Toxicology:• Airway• Breathing• Circulation• Drugs:

• Resuscitation medications if needed• Universal antidotes

• Draw blood: • chemistry, coagulation, blood gases, drug levels

• Decontaminate• Expose / Examine• Full vitals / Foley / Monitoring• Give specific antidotes / treatment

Poisoning in Children• Decontamination:

1. Ocular:– Flush eyes with saline

2. Dermal:– Remove contaminated clothing– Brush off– Irrigate skin

3. Gastro-intestinal:– Activated charcoal:

– May Prevent /delay absorption of some drugs/toxins– Almost always indicated

– Naso/oro-gastric Lavage– Bowel Irrigation:

– Recent ingestions 4-6 hrs– Awake alert patient– 500 cc NS Children / 2000cc adults– Oro / Nasogastric tube

EMERGENCY ANTIDOTES

Primary assessment & intervention

• Vital functions

• Maintain an open airway because some substance may cause soft tissue swelling of the airway.

• Ventilation and oxygenation

• Systemic support for airway security, ventilation, hemodynamic stability, and adequate CNS function

• Careful attention to pain and agitation

Subsequent assessment

• Identify the poison – try to determine the product taken : where, when, why, how much, who witnessed, time since ingestion.

• Call/rush to emergency.

• Obtain blood & urine tests or gastric contents for toxicology screening.

• Monitor fluid & electrolyte imbalance.

General interventionsSupportive care –

• Initiate IV access

• Administer O2

• Monitor & treat shock

• Prevent aspiration(sidelying with head down, use of oropharyngeal airway & suctioning).

• Insert urinary catheter to monitor renal function.

• Support child having convulsion.

• Monitor & treat – hypotension, coma, cardiac dysrrhythmia, seizure

• Gastric lavage (gastric aspirate

for toxicology screening).

• Forced diuresis (increased urine formation by isotonic fluid & diuretics)

• Hemoperfusion (process of blood through an extracorporeal circuit & a cartridge containing an absorbent, such as charcoal, after which the detoxified blood is returned to patient).

• Dermal cleansing with water or normal saline

– Pay close attention to burns, pain, infection

– Water is absolutely contraindicated with reactive metals; use mineral oil instead

– Tar can be removed safely with vaseline

• Hemodialysis

• Providing antidote -

Opiates, Lomotil – NaloxoneIsoniazid – PyridoxineIron – DeferoxamineAtropine – ProstigmineB-blocker – AtropineCA Channel Blocker – GlucagonCarbon Monoxide – OxygenBenzodiazepine - Flumazenil

Management Considerations• Prevention Strategies – (vigilance & firm guiding)

– Store potentially toxic substances in higher places or out of reach/sight or lock

– Store safe items within the child’s reach; don’t take medicine in front of kids

– Avoid keeping chemicals in the fridge

– Remove toxic plants; avoid exposure to toxic animals

– Keep matches, combustibles out of reach

– Dispose of partially consumed alcohol

– Read labels on products carefully

– Label poisonous substances with stickers & teach children

Management Considerations

• Drugs that can kill the toddler in one or two doses!:– Benzocaine, camphor, chloroquine, Lomotil,

Sulfonylureas, theophylline, phenothiazines, hydrocarbon aspiration.

“Prevention is the vaccine for the disease of injury.”

Drowning

DROWNING

• Drowning = process resulting in primary respiratory impairment from submersion/immersion in a liquid medium

• Submersion in a fluid resulting immediate death or death within 24hrs.

• Drowning without aspiration does not occur

Near Drowning

Is a submersion incident in which the individual survives for more than 24 hrs. irrespective of the eventual outcome.

EPIDEMIOLOGY• Freshwater drowning is more

common than saltwater drowning.

• Places: lakes/rivers/canals/pools

• Toddlers:

– Any container of water can be responsible:

• Buckets/fish tanks/washing machine/toilets/bathtub

Drowning modalities• Infants (age <1) - bathtubs, buckets & toilets

• Children ages 1-4 years - swimming pools, hot tubs & spas

• Children ages 5-14 years - swimming pools & open water sites

Near DrowningGroups at Risk

• Toddlers (40% of deaths < 5 yrs.)

• School age boys

• Teenagers

• Males > females (5:1)

• Children with:

– seizures

– cardiac dysrrhythmias

Toddler Drownings• Tend to occur because of

lapse in supervision

• Majority in afternoon/early evening-meal time

• Responsible supervising adult in 84% of cases

• Only 18% of cases actually witnessed

Causes of Near DrowningRecreational Boating

• 90% of deaths due to drowning

• Small, open boats

Recreational Water Activities

20% of deaths :

too few or no

floatation

Other CausesDiving Injuries

• Peak incidence 18-31 years

– No formal training

– 40-50% alcohol related

Ethanol & Water Activities

Epilepsy

• 2.5-4.6% of drowning victims had pre-existing seizure disorder

• Drowned children with epilepsy more likely to: be older than 5, drown in bathtub, not be supervised

• Foley’s catheter

• Bed rest with head elevation

• Monitoring (general condition,T.P.R, BP, I/O)

• Exogenous surfactant

• Re-warming ( 20-30degree to prevent hypothermia)

• ICP monitoring -

Low ICP → Better outcome

High ICP → Poor outcome

• Antibiotics

• Aseptic technique

Predicting Ability for Discharge

• Child can safely be discharged home if at 6 hours :

– GCS > 13

– Normal physical exam/respiratory effort

– Room air pulse oximetry oxygen saturation > 95%

The problem with looking well

Aspiration of water can cause late complications:

• Pulmonary oedema, Pneumonia, Haemolysis, Hepatic & renal failure, bowel necrosis

• Complications of hypothermia
