Nursing attitudes towards charcoal administration--impact on patient care.

In 1990, the American Association of Poison Control Centers identified that for the first time activated charcoal (AC) use had surpassed that of syrup of ipecac. As nurses are given the primary responsibility for AC administration, it was important to determine how AC was being administered, as well as nursing attitudes towards AC that have an impact on patient care. Surveys were mailed to the Emergency Departments (EDs) of 60 hospitals served by the Pittsburgh Poison Center (PPC); 6 nurses/ED, 2 from each shift, were asked to respond. Forty-four EDs responded (73.3%) providing 237 surveys. Eighty-two percent of nurses stated they disliked administering AC for the following reasons: Patients did not like AC (64.4%); AC soiled clothing (54.7%); and AC took too long to give (35.5%). Prior to administration, 70.9% of the nurses responded that they shook the AC a minimum of 20 times; 9.3% commented that AC still failed to resuspend. Specific administration techniques included attempts to mask the appearance the the AC (67.1%) and attempts to increase AC's palatability by adding a flavoring agent (37.6%) or by using AC with sorbitol instead of aqueous AC (25.7%). Of note was that the flavoring agents used were those known to decrease AC's ability to adsorb toxins. As the majority of problems with AC involved its poor resuspendibility and palatability, an AC fact sheet was developed and mailed to EDs to provide suggestions on AC resuspension and means of enhancing patient acceptance without compromising AC's adsorptive capacity. By surveying nursing attitudes toward AC and the administration techniques being utilized, the PPC was able to identify specific problems and address nursing concerns in a way that positively impacts patient care.

Special considerations in gastrointestinal decontamination.

Many considerations factor into selecting the most appropriate method of gastrointestinal decontamination used in the poisoned patient. A thorough knowledge of the indications and efficacy as well as contraindications and complications of each modality is critical to the clinician's assessment. This article examines the current utility of syrup of ipecac-induced emesis, orogastric lavage, activated charcoal, cathartics, and whole bowel irrigation. In addition, the role of multiple dose activated charcoal and the controversial issue of the N-acetylcysteine and activated charcoal interaction are discussed.

[Activated charcoal as first-choice therapy in poisoning].

In gastrointestinal detoxication, three methods are possible: ipecac induced emesis, gastric lavage and administration of activated charcoal. The method of treatment predominantly used in the Netherlands is gastric lavage in combination with activated charcoal. Published evidence suggests that activated charcoal not preceded by gastric emptying is preferred. Additional advantages of using activated charcoal alone as the method of choice for gastrointestinal decontamination are patient friendliness, low cost and time saving because quick intervention by general practitioners is possible.

Oral poisonings: guidelines for initial evaluation and treatment.

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.

Effects of improved access to safety counseling, products, and home visits on parents' safety practices: results of a randomized trial.

OBJECTIVE: To present the results of an intervention trial to enhance parents' home-safety practices through pediatric safety counseling, home visits, and an on-site children's safety center where parents receive personalized education and can purchase reduced-cost products. DESIGN: Pediatricians were randomized to a standard- or an enhanced-intervention group. Parents of their patients were enrolled when the patient was 6 months or younger and observed until 12 to 18 months of age. SETTING: A hospital-based pediatric resident continuity clinic that serves families living in low-income, inner-city neighborhoods. PARTICIPANTS: First- and second-year pediatric residents and their patient-parent dyads. INTERVENTIONS: Parents in the standard-intervention group received safety counseling and referral to the children's safety center from their pediatrician. Parents in the enhanced-intervention group received the standard services plus a home-safety visit by a community health worker. OUTCOMES: Home observers assessed the following safety practices: reduction of hot-water temperature, poison storage, and presence of smoke alarms, safety gates for stairs, and ipecac syrup. RESULTS: The prevalence of safety practices ranged from 11% of parents who stored poisons safely to 82% who had a working smoke alarm. No significant differences in safety practices were found between study groups. However, families who visited the children's safety center compared with those who did not had a significantly greater number of safety practices (34% vs 17% had > or 3). CONCLUSIONS: Home visiting was not effective in improving parents' safety practices. Counseling coupled with convenient access to reduced-cost products appears to be an effective strategy for promoting children's home safety.

Demographic and risk factors associated with chronic dieting in adolescents.

A comprehensive, school-based survey was administered to 36,320 Minnesota public school students in grades 7 through 12 during the 1987-1988 school year. Self-reported chronic dieting was much higher in girls than in boys (12.1% of all girls vs 2.1% of boys). For girls, the percentage of chronic dieters was significantly less in grades 7 and 8 (7.8%) than in grades 9 and 10 (13.5%) or grades 11 and 12 (14.3%). There were no differences among urban, suburban, or rural youth. Black girls were less likely to diet compared with white girls. Chronic dieters were more likely than other students to report maladaptive weight-loss techniques, such as self-induced vomiting (relative risk, 9.92 for girls and 9.40 for boys), laxative use (relative risk, 7.18 for girls and 11.00 for boys), ipecac use (relative risk, 8.33 for girls and 11.00 for boys), and diuretic use (relative risk, 7.30 for girls and 13.5 for boys). It is suggested that chronic dieting may serve as a screening marker for more severe eating and weight-loss behaviors.

Fecal and oral shedding of Helicobacter pylori from healthy infected adults.

CONTEXT: Helicobacter pylori commonly infects humans; however, its mode of transmission remains unknown. OBJECTIVE: To determine how humans-the primary host for H pylori-shed the organism into the environment. DESIGN: Controlled clinical experimental study conducted from February through December 1998. SETTING: Clinical research unit of a hospital in northern California. PATIENTS: Sixteen asymptomatic H pylori-infected and 10 uninfected adults. INTERVENTION: A cathartic (sodium phosphate) and an emetic (ipecac) were given to all infected subjects and an emetic was given to 1 uninfected subject. MAIN OUTCOME MEASURE: Confirmed H pylori isolates cultured from stool, air, or saliva before and after catharsis and emesis and from vomitus during emesis. Isolates were fingerprinted using repetitive extragenic palindromic (REP) polymerase chain reaction and species identity was confirmed by sequencing the 16s ribosomal RNA gene. RESULTS: All vomitus samples from infected subjects grew H pylori, often in high quantities. Air sampled during vomiting grew H pylori from 6 (37.5%) of the 16 subjects. Saliva before and after emesis grew low quantities of H pylori in 3 (18.8%) and 9 (56.3%) subjects, respectively. No normal stools and only 22 (21.8%) of 101 induced stools grew the organism, although 7 (50.0%) of 14 subjects had at least 1 positive culture (2 stool culture samples were contaminated by fungus and were not included). Fingerprints of isolates within subjects were identical to one another but differed among subjects. No samples from uninfected subjects yielded H pylori. CONCLUSIONS: Helicobacter pylori can be cultivated uniformly from vomitus and, occasionally, from saliva and cathartic stools. The organism is potentially transmissible during episodes of gastrointestinal tract illness, particularly with vomiting.

Rumination and vomiting in Prader-Willi syndrome.

Inability to vomit has been cited as characteristic of Prader-Willi syndrome (PWS). Although post-prandial vomiting after gastric by-pass surgery has been reported, neither vomiting under "typical" circumstances or rumination have been described. Prompted by the discovery of several cases of vomiting and rumination, a questionnaire was sent to members of the PWS Association. Approximately 36% (113/313) of affected individuals reportedly experienced at least one episode of vomiting. Induced vomiting was unsuccessful in 9 of 14 cases in whom results were known. However, no complications of Ipecac were reported. We suggest that there is an alteration in the physiologic set-point at which vomiting occurs, leading to a decreased propensity to vomit. Liberal and strict definitions of rumination yielded 15.7% and 10.2% positive responses, respectively. Rumination was associated with a history of vomiting. Enamel deterioration consistent with rumination has been observed, and such changes should be looked for in all PWS children. In several instances, rumination was found to decrease when very strict weight control was lessened. Certain individuals may ruminate under too strict a weight control program, and weight control goals should be evaluated to achieve a reasonable compromise between ideal weight and obesity. Vomiting and rumination do not rule out the diagnosis of PWS.

Experimental emetine myopathy: enzyme histochemical, electron microscopic, and immunomorphological studies.

Ipecac, containing emetine hydrochloride, is used by patients with anorexia nervosa to induce vomiting. Its chronic usage may result in a myopathy and a cardiomyopathy, the former marked by cytoplasmic bodies. We studied myopathological changes after daily injections of female Wistar rats with emetine hydrochloride intraperitoneally for periods of 4, 5, 9, and 10 weeks. The extensor digitorum longus muscle and the soleus muscle showed core-like lesions, streaming of the z-discs, nemaline bodies, cytoplasmic bodies, and spheroid cytoplasmic bodies. Immunomorphological studies revealed increased amounts of desmin. During a period of repair, i.e., 2, 4, and 6 weeks after termination of emetine application, these myopathological alterations faded while proliferation of the T-tubular system, i.e., honeycomb structures, was more often prevalent. Pathological features completely disappeared between 6 and 12 weeks of recovery.

Gastrointestinal decontamination in the emergency department.

Pediatric poisoning is a problem commonly encountered in the emergency department. After stabilization of airway, breathing, and circulation, one of the goals of treatment is decontamination in order to limit poison absorption and the resulting systemic toxicity. Decontamination modalities include gastric emptying (ipecac and gastric lavage), inhibiting absorption (activated charcoal), and catharsis (sorbital, magnesium citrate, and whole bowel irrigation). Each modality is discussed. Choice of modality by the practitioner must be individualized to each patient's situation.

Unreported sauna use in anorexia nervosa: evidence from the world-wide-web.

Weight loss methods employed in anorexia nervosa (AN) are vomiting, laxatives, diuretics, enemas, suppositories, ipecac, weight loss medications and inadequate insulin in diabetics. Some methods result in weight loss from fluid depletion and not a reduction in body fat. Sauna use causes rapid fluid loss, but has not been reported in the medical literature as a weight loss strategy used in AN. We found reports of sauna use in AN on the world-wide-web are rare. We hypothesize that the warming caused by the use of sauna, may result in physical improvement in AN and thereby reduce its acceptability as a weight loss strategy.

Rheumatic manifestations of diseases associated with substance abuse.

Rheumatic manifestations of substance abuse are uncommon but recognized complications. Repeated injections of drugs and adulterants represent repeated antigenic challenge. The population at greatest risk is that of young males, although females with eating disorders are more apt to develop myopathy, clubbing, or periostitis. Alcohol, the most common substance abused, is associated more often with myopathy. In IV drug abusers, hepatitis B viral infection, bacterial endocarditis, primary skeletal infections, and venous complications are most common in that order. However, the spectrum may evolve as the pattern of substance abuse changes. First, the frequency of cocaine dependence is rapidly approaching that of alcohol. Two regular cocaine users are reported as having Raynaud's phenomenon and abnormal serologies. Second, synthesis of lookalike drugs may produce new associations, such as parkinsonism after IV N-methyl-4-phenyl-1,2,3,6-tetrahydropyridine. Third, the increased use of ipecac and purgatives in eating disorders is an important consideration in young women with otherwise unexplained myopathy or arthritis. Finally, patients with AIDS are presenting with autoimmune phenomena or a spectrum of unusual infections that change as the epidemic evolves. Increased recognition of these symptom complexes may lead to earlier, more accurate diagnoses and avoidance of unnecessary diagnostic evaluations and delays in treatment.

Hypokalemia in acute theophylline poisoning.

The frequency, severity, and time of occurrence of hypokalemia and their relationship with vomiting was studied in 40 patients with acute theophylline poisoning. The mean peak theophylline concentration was 58 micrograms/mL (range, 21 to 115), and the mean nadir of serum potassium was 3.0 mEq/L (range, 2.1 to 3.9). In 85% of the patients, the nadir of serum potassium was less than 3.5 mEq/L; 45% had potassium concentrations of less than 3 mEq/L. The severity of hypokalemia correlated with peak serum theophylline concentrations (p less than 0.001). Hypokalemia was observed early in the course of the overdose (mean, 5 hours after ingestion or administration of theophylline). The nadir in serum potassium concentrations was more severe among 25 patients who presented to the emergency department within 6 hours of the overdose than among 13 patients who presented later (mean +/- SE, 3.0 +/- 0.1 mEq/L vs 3.4 +/- 0.1 mEq/L, p less than 0.01), despite similar admission serum theophylline concentrations in both groups (49 +/- 5 and 55 +/- 5 micrograms/mL, respectively; p = not significant). Spontaneous or ipecac-induced emesis occurred in 95% of the patients; however, hypokalemia preceded vomiting in 13 patients. Its severity was similar whether patients did or did not vomit before its occurrence. Hypokalemia is a frequent manifestation of acute theophylline poisoning, has a very early onset, and occurs independently of vomiting, suggesting an intracellular shift of potassium.

Prehospital pharmacotherapeutic interventions: recommendations for medication administration by EMT-A and EMT-I personnel.

Because many communities lack prehospital advanced life support (ALS) services, increasing public access to such care is important. The present study was completed to establish an epidemiological database defining prehospital pharmacotherapeutic interventions by ALS rescue teams, in the hope of developing recommendations for medication administration by non-ALS personnel. Data were collected on 333 patients, including indication for pharmacotherapy, patient age, ambulance field time, route of medication administration, adverse effects of pharmacotherapy, efficacy of pharmacotherapy, additional ALS interventions, and patient medication/past medical history. Medications studied included albuterol nebulizer treatments (albuterol), aminophylline, amyl nitrite, atropine, bretylium tosylate, dexamethasone sodium phosphate, dextrose 50% (D-50), diazepam, diphenhydramine, dopamine, epinephrine 1 mg/1 mL, epinephrine 1 mg/10 mL, furosemide, glucagon, ipecac, isoproterenol, lidocaine, morphine sulfate, naloxone, nitroglycerin tablets (nitroglycerin), sodium bicarbonate, and verapamil. Albuterol, D-50, and nitroglycerin were used more often than other medications, accounting for total pharmacotherapeutic interventions for 228 persons (68.47% of total patients), including 100% of all pediatric patients. Partial pharmacological needs for an additional 20 patients also were satisfied by these agents. In all, albuterol, D-50, and nitroglycerin accounted for 250 of 395 total medication interventions (63.29%). No inappropriate use, point estimate [(0)/(333) (0.00% to 0.90%)], or unmet need, point estimate [(0)/(3,613) (0.00% to 0.08%)], of care was noted. When faced with communities lacking ALS rescue services, albuterol, D-50, and nitroglycerin are recommended for administration by emergency medical technician-ambulance and intermediate level rescuers, because of the high rate of use, relative ease of administration, and high benefit/low complication rates associated with these medications.

The new black magic: activated charcoal and new therapeutic uses.

Activated charcoal has been used for centuries as antidotal therapy for poisonings. New variations of charcoal therapy have developed over the last two decades. These modifications include multiple-dose activated charcoal (MDAC) therapy, charcoal hemoperfusion, and a new "superactive" charcoal (SAC). Recent literature suggests using initial charcoal therapy instead of ipecac as a first-line antidotal agent for many acute poisonings. The palatability of charcoal slurries has been enhanced by the addition of carboxymethylcellulose, sucrose, saccharin, chocolate syrup, or sorbitol. The new SAC has shown to adsorb 1.7 to 4 times the amount of substance tested compared with other activated charcoal preparations. Multiple-dose activated charcoal therapy has been shown effective in treating phenobarbital, digoxin, digitoxin, theophylline, and dapsone intoxications, among others. The problems associated with charcoal hemoperfusion therapy have been partially alleviated, and it is now alternative therapy for the seriously intoxicated patient.

Evaluation of kiosk-based tailoring to promote household safety behaviors in an urban pediatric primary care practice.

We tested a kiosk-based tailoring intervention with a sample of 144 parents of young children using a two-group randomized controlled design to evaluate the kiosk. Intervention group parents (n = 70) answered 50 questions at a practice-based kiosk and they and their child's physician received immediate feedback reports of their injury prevention needs. Four weeks later, both control (n = 74) and intervention parents completed a telephone interview. Safety knowledge, beliefs, and practices were compared at follow-up. Compared to control group parents, intervention group parents were more knowledgeable about the inappropriateness of young children riding in the front seat of a car (16% versus 5%, p < 0.05), less likely to believe that teaching a child to mind you is the best way to prevent injuries (64% versus 86%, p < 0.05), and more likely to report that they "have syrup of ipecac" (34% versus 9%, p < 0.001) and "know how to use" it (24% versus 4%, p < 0.002). This study provides further support for the use of tailored communication to address the prevention of injuries to young children but calls for continued investigation in the area.

HIV-1 and HIV-2 reverse transcriptases: a comparative study of sensitivity to inhibition by selected natural products.

One hundred and fifty six pure natural products, which had previously been tested against HIV-1 reverse transcriptase, were evaluated for HIV-2 reverse transcriptase inhibitory activity. Compounds that lacked effect in the HIV-1 reverse transcriptase system were found also to be inactive against HIV-2 reverse transcriptase. However, compounds belonging to the benzophenanthridine and protoberberine classes of alkaloids, certain flavonoids, the iridoid, fulvoplumierin, and the ansamycin antibiotic, daunomycin, exhibited similar potencies in both enzyme systems. In contrast, HIV-2 reverse transcriptase was observed to be four-fold more sensitive toward the inhibitory effects of the ipecac alkaloids, O-methylpsychotrine sulfate heptahydrate and psychotrine dihydrogen oxalate. Such differences in susceptibilities to inhibitors may indicate subtle dissimilarities in enzyme structure and function.

Approach to the poisoned patient.

Routine poison management involves the following: (1) stabilization, (2) toxidrome recognition, (3) decontamination, (4) antidote administration, (5) enhanced elimination of toxin, and (6) supportive care. Stabilization involves airway, ventilation, and circulation support. In the patient with altered mental status, oxygen, naloxone, glucose, and thiamine should be administered. Symptom complexes that relate to specific classifications of toxins are referred to as toxidromes. Emesis by means of syrup of ipecac is rarely used for in-hospital gastric decontamination. Activated charcoal is a useful adsorbent for gastric decontamination. Whole bowel irrigation is useful for iron, lead, and lithium poisoning and for the body packer phenomenon. Enhancement of elimination may involve multiple doses of activated charcoal, hemodialysis, or charcoal hemoperfusion.
