The cardinal principle of the management of the poisoned patient is meticulous supportive care.
Gastrointestinal decontamination plays a limited role in the routine management of poisoned patients.
Ipecac-induced emesis, gastric lavage, and cathartics should not be considered in the poisoned child.
Activated charcoal or whole bowel irrigation (WBI) are potential interventions in a limited number of patients.
Antidotes are available for a limited number of poisonings.
Over the past several decades, fatalities associated with pediatric poisoning have fallen steadily, from 450 deaths in 1960 to just 50 in 2015; 42 of these were in patients 5 years old or younger.1 Interventions such as child-resistant packages, poison-education programs designed to increase household awareness of potential toxins, and improved intervention at both the poison center and hospital levels have all contributed to this decrease in pediatric mortality to just 2.3% of all poisoning deaths.1
However, pediatric exposures account for approximately 60% of all poisonings reported to the nation’s poison control centers, as noted by the most recent annual report from the American Association of Poison Control Centers.1 This report also shows that nearly half of all pediatric exposures occurred in children 5 years of age or younger. Fortunately, most of these tend to be unintentional ingestions of small doses and thus result in minimal toxicity. However, most adolescent and adult poison exposures are purposeful, involving larger doses, and thus result in greater morbidity and mortality. These intentional exposures include suicide gestures, recreational substance use, and Munchausen syndrome by proxy.2
HISTORY AND PHYSICAL EXAMINATION
It is often difficult to obtain an accurate history. In children who are either too young to provide specific details, or who have an altered level of consciousness from their ingestion, alternative sources of information should be considered. Essential historical points include the specific identification of the substance, when it was ingested, the amount ingested, and what other medications or poisons are available in the home. If possible, sending a family member back to the home to collect pill bottles, including over-the-counter and herbal supplements/vitamins, can be very informative. Overall, it is prudent to assume the worst-case scenario until proven otherwise.2–4
The physical examination may provide valuable information regarding the ingestion or exposure. Specific focus upon vital signs and level of consciousness is paramount in assessing the degree of toxicity. Many drugs and toxic agents have specific effects on the heart rate, respiratory rate, blood pressure, and temperature; as such, vital sign monitoring is of the utmost importance (Table 113-1). The level of consciousness, pupil size, and the presence of coma or seizures may provide clues regarding the identity of the ingested poison (Tables 113-2 and 113-3). Other diagnostic clues may be obtained from examination of the skin (Table 113-4) and breath odor (Table 113-5). Several ...
