BURN
Require only symptomatic treatment.
Usually heals in 7 days.
No blister formation.
Skin is red, painful, and tender.
Involves only the Epidermal layer of the skin.
Leaves no scars.
I= 1st DEGREE BURN
The deeper layer of the dermis, hair follicles, sweat glands and sebaceous glands are spared
II= 2nd DEGREE BURN1- SUPERFICIAL – PARTIAL THICNESS The burn extends to the dermis
The epidermis and superficial (papillary layer) dermis are injured
Blistering of the skin
Exposed dermis is red, moist at blister base
Very painful to touch
Good perfusion of dermis with intact capillary refill
Heal in 14 – 21 days
Scaring usually minimal
II= 2nd DEGREE BURN2- DEEP – PARTIAL THICKNESS
Extends into the deep reticular layer of the dermis
There is damage in the hair follicles, sweat glands, & sebaceous glands
Caused by steam, hot liquids, flameSkin may be blisteredThe burned areas don’t blanchNo capillary fillingAbsent pain sensationHealing takes 3 W – 2 monthsScaring is commonSurgical debridement & skin grafting may be necessary to obtain maximum function
III= 3rd DEGREE BURN
Involves the entire skin thickness
All epidermal and dermal layers are destroyed
Caused by flame, hot oil, steam and contact e’ hot object
Skin is charred, pale, painless, leathery
Injuries will not heal spontaneously
Surgical repair and grafting are necessary
Injuries will leave significant scaring

3. Toxins:MethanolEthylene glycolPropylene GlycolLactic acidUremiaAspirinPhenforminIronIsoniazidCyanide
4. Renal failure, causes high anion gap acidosis by decreased acid excretion and decreased HCO3
− reabsorption. Accumulation of sulfates, phosphates, urate, and hippurate accounts for the high anion gap.

Helpful in establishing a diagnosis when the exposure is not well defined.
Certain clinical findings may narrow the etiologic possibilities
Common Toxic Syndromes (Toxidromes) Anticholinergic Common
signs
Delirium with mumbling speech, tachycardia, dry flushed skin, dilated pupils, myoclonus, slightly elevated temperature, urinary retention, decreased bowel sounds. Seizures and dysrhythmias may occur in
severe cases.
Common causes
Antihistamines, antiparkinsonians, atropine, scopolamine, amantadine, antipsychotics, antidepressants, antispasmodics, mydriatics, muscle relaxants.
Sympathomimetic
Common signs
tachycardia (or bradycardia with pure a-agonist), hypertension, hyperpyrexia, diaphoresis, Delusions, paranoia, piloerection, mydriasis,
hyperreflexia. Seizures, hypotension, and dysrhythmias. Common causes
Cocaine, amphetamine, methamphetamine and its derivatives, ephedrine, pseudoephedrine. In caffeine and theophylline overdoses, similar findings, except for the organic psychiatric signs, result from
catecholamine release.
Common Toxic Syndromes (Toxidromes) Opioid/sedative/ethanol Common
signs
Coma, respiratory depression, miosis, hypotension, bradycardia, hypothermia, pulmonary edema, decreased bowel sounds, hyporeflexia, needle marks. Seizures may occur after overdoses of some narcotics
(e.g., propoxyphene) Common causes
Narcotics, barbiturates, benzodiazepines, glutethimide, methyprylon,
methaqualone, meprobamate, ethanol, clonidine, guanabenz
Cholinergic Common
signs
Confusion, central nervous system depression, weakness, salivation, lacrimation, urinary/fecal incontinence, gastrointestinal cramping, emesis, diaphoresis, muscle fasciculations, pulmonary edema, miosis,
bradycardia/tachycardia, seizures Common causes
Organophosphate and carbamate insecticides, physostigmine,
