Selected tricyclic antidepressant ingestions involving children 6 years old or less.

OBJECTIVE: According to the annual report of the American Association of Poison Control Centers, tricyclic antidepressant (TCA) ingestions accounted for 15,708 exposures in 1998, of which 70% (all age groups) were treated at health care facilities (HCFs), with an estimated 2,022 children less than 6 years of age exposed. The study objective was to evaluate the manifestations, referral patterns, HCF management, and medical outcomes in pediatric patients 6 years old or less with TCA ingestions reported to a regional poison control center. METHODS: All TCA (amitriptyline, clomipramine, desipramine, doxepin, imipramine, nortriptyline) ingestions from January 1, 1993, to December 31, 1997, involving patients aged 6 years or less managed by the poison control center were evaluated for dose, symptoms, treatments, disposition, and outcome. RESULTS: Forty-four of 48 patients (92%) were asymptomatic. All were single-drug exposures. Forty-three patients (90%) ingested a TCA dose that was less than the normally prescribed pediatric dose (5 mg/kg). Of the five children ingesting >5 mg/kg (range 5-9.4 mg/kg), only one (5.3 mg/kg) was mildly symptomatic (drowsy) prior to admission. Thirty-one of the 48 (65%) were sent to the emergency department (dose range 0.59-9.4 mg/kg). Fourteen of the 31 were admitted for 12-24-hour observation and none subsequently developed symptoms. Twenty-three (74%) received activated charcoal (AC). There was no difference in outcome between the children who did and did not receive AC. CONCLUSIONS: No case of significant toxicity occurred in the children who experienced unintentional TCA ingestions in this study population. None of the children in the study had toxicity at doses <5 mg/kg. Further study is necessary to develop clinical guidelines for the appropriate referral of unintentional ingestions of TCA involving children.

A nationwide survey of the management of unintentional-low dose tricyclic antidepressant ingestions involving asymptomatic children: implications for the development of an evidence-based clinical guideline.

BACKGROUND: The triage of unintentional tricyclic and cyclic antidepressant ingestions involving children <6 years seems based on single cases or small studies. Walsh, in describing 2 cases involving 15-20 mg/kg ingestions, recommended hospitalizing all children ingesting tricyclic and cyclic antidepressants. OBJECTIVE: To evaluate the patterns of triage for pediatric tricyclic and cyclic antidepressants practiced by regional poison control centers nationwide, and to determine the amount ingested (mg/kg) that resulted in referral to the emergency department, including the recommended duration of observation time for asymptomatic children. Second, to analyze the cost implications, as well as the need for a practice guideline based on severity stratification. METHODS: We sent a survey to 44 major regional poison control centers. We reviewed Health Care Financing Administration's tricyclic and cyclic antidepressants management related costs. RESULTS: Thirty centers responded (68%). Eighty-seven percent of all centers send children, regardless of dose ingested, to the emergency department. Four out of the 30 recommended observation based on dose in mg/ kg ingested (range >1.5-5). Recommended observation times in the emergency department varied between 6-24 hours. Twenty-seven (90%) Poison Control Centers recommended 6 hours (although one recommended doing so only after administering activated charcoal). One recommended 6-12 hours of observation and 2 Poison Control Centers recommended 24-hour observation. Only 1 center recommended obtaining tricyclic and cyclic antidepressant plasma levels. DISCUSSION: In our review of the literature, the lowest toxic dose reported was 6.7 mg/kg. This is consistent with our Poison Control Center data over the past 5 years where no child was toxic at doses <5 mg/kg. While only 13% of the centers surveyed utilize a stratification strategy to triage pediatric tricyclic and cyclic antidepressant ingestions, the current referral patterns support evaluation based on pharmacokinetics, not worst case incidents. CONCLUSION: This survey demonstrates that most children with tricyclic and cyclic antidepressant ingestions will be sent to the emergency department, regardless of the amount ingested. A prospective study is needed to determine the probable dose of tricyclic and cyclic antidepressant ingestions that requires observation at a health care facility.

Hydrogen peroxide 3% exposures.

OBJECTIVE: To present a child who developed gastric ulcers and duodenal erosions after ingestion of hydrogen peroxide 3% and delineate the epidemiology, medical outcomes, and toxicity of exposures to this agent managed by a poison control center. METHODS: A retrospective chart review of exposures to hydrogen peroxide 3% reported to the Long Island Regional Poison Control Center from January 1992 to April 1995 was conducted. Data extracted included age, route of exposure, amount of agent, symptoms, therapy, and medical outcome. RESULTS: There were 670 exposures to hydrogen peroxide 3% of 81,126 total exposures reported during the 40 months. Most exposures were by oral route (77%), occurred in children < 17 years old (67%), and were asymptomatic (85.6%). All but one exposure resulted in a benign outcome. One child, who presented with bloody emesis, developed multiple gastric ulcers and duodenal erosions after ingestion of hydrogen peroxide 2-4 oz. CONCLUSIONS: Exposure to hydrogen peroxide 3% is usually benign, however, severe gastric injury may occur following small ingestions in children. Patients who report persistent vomiting or bloody emesis require medical evaluation and consideration of endoscopy to evaluate gastrointestinal injury.

Mercuric chloride poisoning due to ingestion of a stool fixative.

We present a case of ingestion of a commonly used stool fixative containing 675 mg of mercuric chloride per 15 mL vial. Early chelator therapy with dimercaprol and aggressive hydration were initiated and the patient remained asymptomatic. Safety packaging of this product is recommended.

Magnesium intoxication in a neonate from oral magnesium hydroxide laxative.

This is a case of magnesium intoxication in a neonate produced by an oral magnesium cathartic. A review of the literature revealed there are very few cases that have been reported of magnesium toxicity due to cathartics. There is no recommended dose for magnesium cathartics in neonates or data on their safety. A review of the management of magnesium intoxication is presented.

Acetaminophen induced pancreatitis.

This is the fourth reported case of acute pancreatitis associated with acetaminophen overdose. The patient had ingested the smallest amount of acetaminophen (9.75-13 g) that has been reported to produce acute pancreatitis. This patient also suffered liver and renal impairment and developed an ileus and ascites. Despite late therapy and laboratory tests that indicated a poor prognosis the patient made a complete recovery without sequelae.
