Recognition and Management of Acute Pesticide Poisoning - Article

ABSTRACT: Most poisonings from pesticides do not have a specific antidote, making decontamination the most important intervention. For maximal benefit to the patient, skin, eye, and gastric decontamination should be undertaken while specifics of the poisoning are being determined. As in most illnesses and injuries, the history of the poisoning is of great importance and will determine specific needs for decontamination and therapy, if any exist. Protection of health care workers during the decontamination process is important and frequently overlooked. Skin decontamination is primarily accomplished with large volumes of water, soap, and shampoo. Gastric decontamination by lavage is indicated if ingestion of the poisoning has occurred within 60 minutes of patient presentation. Activated charcoal, combined with a cathartic, is also indicated in most poisonings presenting within 60 minutes of ingestion. With large volume ingestion poisonings, activated charcoal may be used after 60 minutes, but little data exist to support this practice. Syrup of ipecac is no longer recommended for routine use. The cholinergic syndrome "all faucets on" characterizes poisoning by organophosphates and carbamates. Organochlorine insecticides (lindane and other treatments for scabies and lice) can produce seizures with excessive use or use on large areas of nonintact skin. Non-dipyridyl herbicides, biocides (including pyrethrins, pyrethroids, and Bacillus thuringiensis) rarely produce anything other than mild skin, eye, and/or gastrointestinal irritation on topical exposure or ingestion.

Poisoning, Envenomation, and Trauma from Marine Creatures - Article

ABSTRACT: In the course of their clinical work or during leisure activity, family physicians occasionally may encounter patients with injuries from marine creatures. Poisoning, envenomation, and direct trauma are all possible in the marine environment. Ciguatera poisoning can result from ingestion of predatory fish that have accumulated biotoxins. Symptoms can be gastrointestinal or neurologic, or mixed. Management is mostly symptomatic. Scombroid poisoning results from ingestion of fish in which histamine-like substances have developed because of improper refrigeration. Gastrointestinal and systemic symptoms occur. Treatment is based on antihistamines. Envenomations from jellyfish in U.S. waters and the Caribbean are painful but rarely deadly. Household vinegar deactivates the nematocysts, and manual removal of tentacles is important. Treatment is symptomatic. Heat immersion may help with the pain. Stingrays cause localized damage and a typically severe envenomation. The venom is deactivated by heat. The stingray spine, including the venom gland, typically is difficult to remove from the victim, and radiographs may be necessary to localize the spine or fragment. Surgical débridement occasionally is needed. Direct trauma can result from contact with marine creatures. Hemorrhage and tissue damage occasionally are severe. Infections with organisms unique to the marine environment are possible; antibiotic choices are based on location and type of injury. Shark attacks, although rare, require immediate attention.

Evaluation and Management of Common Childhood Poisonings - Article

ABSTRACT: Family physicians often manage substance ingestions in children, most of which are nontoxic in nature. Physicians should know the phone number of the poison control center, understand the appropriate initial assessment of suspected toxin ingestion, and recognize important toxidromes. Rapid triage is crucial, including airway, respiration, and circulation stabilization. Appropriate supportive or toxin-specific treatment should be initiated. Gastric decontamination, such as activated charcoal and gastric lavage, are no longer routinely recommended. These methods should be reserved for the most severe cases, with poison control center support. The use of ipecac is no longer recommended. A child with few symptoms or a witnessed toxin exposure may be monitored at home. However, some long-acting medications have delayed toxin effects and require additional surveillance.

Treatment of Ethylene Glycol Poisoning - Article

ABSTRACT: Ingestion of ethylene glycol may be an important contributor in patients with metabolic acidosis of unknown cause and subsequent renal failure. Expeditious diagnosis and treatment will limit metabolic toxicity and decrease morbidity and mortality. Ethylene glycol poisoning should be suspected in an intoxicated patient with anion gap acidosis, hypocalcemia, urinary crystals, and nontoxic blood alcohol concentration. Fomepizole is a newer agent with a specific indication for the treatment of ethylene glycol poisoning. Metabolic acidosis is resolved within three hours of initiating therapy. Initiation of fomepizole therapy before the serum creatinine concentration rises can minimize renal impairment. Compared with traditional ethanol treatment, advantages of fomepizole include lack of depression of the central nervous system and hypoglycemia, and easier maintenance of effective plasma levels.

Oral Poisonings: Guidelines for Initial Evaluation and Treatment - Article

ABSTRACT: The initial evaluation and management of poisoned patients should be comprehensive and include an accurate history whenever possible, stabilization of the patient's condition, a physical assessment to evaluate the extent of poisoning and the presence of concurrent conditions, decontamination of the gastrointestinal tract using activated charcoal, gastric lavage, administration of ipecac or irrigation, poison-specific treatment with administration of antidotes when indicated and proper disposition. Consultation with a poison control center is often helpful in assessing and treating these patients.

Prevention of Unintentional Childhood Injury - Article

ABSTRACT: Unintentional injury accounts for 40 percent of childhood deaths annually, most commonly from motor vehicle crashes. The proper use of child restraints is the most effective strategy to prevent injury or death. Motor vehicle restraint guidelines have recently been revised to an age-based system that delays the progression in type of restraint for most children. Strategies to prevent suffocation in children include using appropriate bedding, positioning babies on their backs to sleep, and removing items from the sleep and play environment that could potentially entrap or entangle the child. Fencing that isolates a swimming pool from the yard and surrounding area and “touch” adult supervision (i.e., an adult is in the water and able to reach and grab a child) have been shown to be most effective in preventing drownings. Swimming lessons are recommended for children older than four years. Poison prevention programs have been shown to improve prevention behavior among caregivers, but may not decrease poisoning incidence. Syrup of ipecac is not recommended. Smoke detector maintenance, a home escape plan, and educating children about how to respond during a fire emergency are effective strategies for preventing fire injuries or death. Fall injuries may be reduced by not using walkers for infants and toddlers or bunk beds for children six years and younger. Consistent helmet use while bicycling reduces head and brain injuries. Although direct counseling by physicians appears to improve some parental safety behaviors, its effect on reducing childhood injuries is uncertain. Community-based interventions can be effective in high-risk populations.
