The equipment necessary for endotracheal intubation is outlined in Box 2A-2 . Rocuronium appears to have the most rapid onset of all nondepolarizing agents, approaching that of succinylcholine with regard to time to complete muscle relaxation in the less than ideal conditions generally found during emergency intubation.15 Significant warnings to succinylcholine use in the pediatric population have been recently added, based on the possibility of life-threatening cardiac arrhythmias. Consider continuous ECG monitoring for critically unwell patients (e.g. Poison, as defined by 139 (93.3%) of them, is any substance capable of causing damage or dysfunction in the body through its chemical action. Bradycardia is common after the overdose of four classes of cardiac agents: calcium channel blocker, blocking agents, digitalis preparations, and central 2 antagonists (e.g., clonidine or guanfacine). Ivermectin intoxication was suspected, since encephalopathy and coma are well-known side effects of ivermectin treatment in animals and the usual causes of coma had been ruled out. Is the patient eating a special diet or taking a new health food, alternative medication, or performance enhancer? 2. Rarely, the tricyclic antidepressants have been known to cause fatal arrhythmia up to 3 days following ingestion. Decisions around decontamination must be individualized. Twitter: http://www.twitter.com/geekymedics This shows the unit in predeployment position. The reader is referred to Chapter 103 and to the recent Occupational Safety and Healthy Administration (OSHA) best practices document.7. He suggested that vigorous gastric aspiration (likewise considered controversial given the risk for esophageal or gastric perforation) prior to cold fluid lavage is the treatment of choice in patients treated immediately following acid ingestion.15 A recent experimental study involving irrigation of rat skin exposed to 2N NaOH with 5% acetic acid suggests that neutralization may not always be contraindicated. In addition, there are problems with the process of evidence-based reviews themselves. The assessment of metabolic acidosis includes not only arterial (or, less ideally, venous) blood gas analysis, but also studies of serum sodium, potassium, chloride, carbon dioxide, blood urea nitrogen (BUN), creatinine, glucose, acetone, serum osmolality, and urine pH, as well as urinalysis. furosemide) and strict fluid balance monitoring. Wason S, Baker RC, Carolan P. Carbamazepine overdosethe effects of multiple dose activated charcoal. American Academy of Clinical Toxicology; European Association of Poisons Centres and Clinical Toxicologists. Brown RS., Jr. MARS preconditioning for living donor liver transplantation: panacea or placebo? The dose of ipecac is 5 to 10 mL in children 6 to 12 months of age or 15 mL in children 1 to 12 years of age. Request a CT head if intracranial pathology is suspected after discussion with a senior. Intubation offers the advantages of complete airway control, protection from aspiration of gastric contents, provision of a route for suctioning of secretions, and a means of optimizing both oxygenation and ventilation. One must take into account the patient's underlying health (renal or hepatic insuf-ficiency), the toxicity of the absorbed substance, the presence of or likelihood of advancing to severe illness, the availability of these procedures, and the availability of acceptable alternatives (good supportive care, antidotes). Solely, the dose determines that a thing is not a poison. <> cAMP, cyclic adenosine monophosphate; DMSA, dimercaptosuccinic acid; EDTA, ethylenediaminetetraacetic acid; G6PD, glucose-6-phosphate deficiency; IM, intramuscularly; IV, intravenously. Knepshield JH, Schreiner GE, Lowenthal DT, Gelfand CM. 98. Dialysis of poisons and drugsannual review. Symptom complexes, or toxidromes (Table 2A-5 Until recently, because the airway of the young child has an area of narrowing (physiologic cuffing), cuffed endotracheal tubes were not used in the pediatric patient. Hellinger A, Wolter K, Marggraf G. Elimination of amrinone during continuous venovenous haemofiltration after cardiac surgery. In all overdose patients, aspiration pneumonitis, the result of a depressed gag reflex, is a possibility. This is a PDF-only article. Nausea and vomiting are not uncommon. These include metals (lithium, sodium, iron, potassium) and alcohols. Topical treatments for hydrofluoric acid dermal burns. adverse drug reaction, meningococcal sepsis), bruising (e.g. Assess the patients calves for erythema, swelling and tenderness which may suggest a deep vein thrombosis. Because the process of drug approval is more rapid, it is often not until the agent has been in use for some time, during the postmarketing period, before its toxicity is fully appreciated. Observation may be necessary to evaluate or treat complications, such as in a patient with an overdose who fell and sustained trauma or in a patient who develops aspiration pneumonitis or interstitial pulmonary edema. The study group found no published clinical studies that investigated the ability of a cathartic, with or without activated charcoal, to reduce the bioavailability of drugs or to improve the outcome of poisoned patients. Severe metabolic acidosis accompanying methanol and ethylene glycol, as well as other toxic alcohol poisonings, is a clear indication for HD, regardless of blood concentration. Peritoneal dialysis in acute poisoning: successful treatment of a 15-month-old child ingesting 30 times the adult dose of Achrocidin. Sodium bicarbonate may also be effective in the treatment of other overdose by other agents associated with prolongation of the QRS interval, including diphenhydramine and cocaine. Animals undergoing water irrigation at 1 or 3 minutes postexposure demonstrated some benefit; however, animals irrigated at 10 minutes had no appreciable improvement in pH, compared with control.8 These investigators had previously demonstrated lack of efficacy of water irrigation after 10 minutes in a 2N NaOH burn model.9 Clearly time is of the essence in irrigation of corrosive exposures. For example, the available studies suggest that MDAC likely would not be beneficial in unselected cases of digoxin poisoning. Acute isopropyl alcohol intoxication. Alcohol is the most common odor detected on the breath of an intoxicated patient in the emergency department. Amitai Y, Lovejoy FH. Adverse effects from glucagon include hyperglycemia, nausea, vomiting, and ileus. Several barbiturates can produce rapid sedation and relaxation. CAVH, continuous arterial-venous hemofiltration; CVVH, continuous venovenous hemofiltration; HD, hemodialysis; PD, peritoneal dialysis. Bledsoe GH, Schexnayder SM. Al-Khafaji AH, Dewhirst WE, Manning HL. Magnesium-containing cathartics must be avoided in patients with renal insufficiency and heart block. Effect of activated charcoal on absorption of nortriptyline. 6 0 obj Diagnosis and management. Therefore, in children younger than 5 years, atropine should be administered before induction. Glucagon is theoretically most effective after blocker overdose, in which decreased -adrenergic receptor activation leads to diminished cAMP production. 91. Careful evaluation of individual cases should guide the decision to use extracorporeal circulation. Inflation of the endotracheal tube cuff should be performed to minimize aspiration of gastric contents (although aspiration of activated charcoal around cuffed endotracheal tubes is a frequent occurrence). See text for details on individual decontamination procedures, indications, and contraindications. Severe hypermagnesemia due to multiple-dose cathartic therapy. 2 0 obj Finally, succinylcholine-induced muscle depolarization can lead to transient increases in intracranial and intra-abdominal pressure, with accompanying changes in cardiac output.14 Because of these potential adverse effects, nondepolarizing muscle relaxants are often recommended as adjuncts to or substitutes for succinylcholine use. This is due to its very large Vd.22 The Vd is the theoretical volume into which a drug distributes in the body and is generally expressed in liters or liters/kg body weight. cellulitis). As such, this product cannot be currently recommended for human use. Failure of oral activated charcoal to accelerate the elimination of amiodarone and chloroquine. Qureshi T, Melonakos TK. In the past, there have been theoretic concerns that dopamine's -adrenergic effect in the face of phenothiazine or tricyclic antidepressant intoxication would increase the peripheral vasodilatation associated with overdose, exacerbating hypotension. hypoglycaemia or hyperglycaemia). The investigators demonstrated more rapid correction of pH, no difference in peak temperatures, and improved outcomes in animals treated with 5% acetic acid rather than water. Despite of the use of coated charcoal, the patient developed severe hemolysis, which the researchers attributed to mechanical damage to red cells by the high flow rate through the cartridge. On the contrary, cathartics may induce significant harm in certain groups of patients, particularly children and those with renal disease. Amrinone may be particularly valuable in the treatment of calcium channel blocker intoxication; its inhibition of cAMP breakdown results in greater phosphorylation of L-type calcium channels, potentially increasing their permeability. It is fair to say that the evidence for efficacy is currently deficient, but that lack of efficacy has not been proven either. After poisoning, intravascular volume may decrease abruptly. Discuss the patients current clinical condition with a senior clinician using an SBARR style handover. MARS or albumin dialysis may be of clinical benefit in selected poisonings. Continuous cardiac and pulse oximetry monitoring is essential. At therapeutic concentrations, 90% to 95% of valproic acid is protein bound, but in overdose the degree of protein binding is relatively less (i.e., there is more unbound drug available for extracorporeal purification). For example, if a patient with significant ethylene glycol poisoning arrives at the hospital before the onset of acidosis and renal failure, early treatment with fomepizole alone may preempt the need for HD.25, Hemodial Int 2006;10(2):162167. Both Diphoterine and Hexafluorine are indicated for skin and eye decontamination.*. Other types of dialysis exist that also usually do not require arterial access and are more versatile in that they do not pose as great a hemodynamic stress to the patient; however, they also are generally much slower in their rates of clearance. GCS<8), Other specialists depending on the suspected pathology (e.g. The standard regimen for seizure control in overdose of an unknown agent is use of the full therapeutic dosages of benzodiazepines (e.g., diazepam or lorazepam), followed by administration of phenytoin or a barbiturate (e.g., phenobarbital or pentobarbital). This complication has been reduced by coating of the sorbent particles with a polymer solution.2 Hypocalcemia likewise may occur.35 Rahman and colleagues recently reported on the case of a patient treated with CHP for valproate poisoning. [Water intoxication following gastric lavage]. Pediatric rapid sequence intubation: a review. Hommann M, Kasakow LB, Geoghegan J. .

Pond SM. Lithium has been used as the gold standard in the treatment of major depressive and bipolar disorders for decades. Ho JL, Tierney MG, Dickinson GE. Induction consists of two components: administration of a sedative/anesthetic agent to produce unconsciousness, and the subsequent administration of an agent that produces complete skeletal muscle relaxation (paralysis); both actions facilitate intubation. A formal cost-benefit analysis of these various treatment options would be useful. and transmitted securely. Gasoline, camphor, hydrogen sulfide, ether, turpentine, methyl salicylate, paraldehyde, phenol, and organophosphate insecticides all have characteristic odors. Givens T, Holloway M, Wason S.

Arterial blood gas analysis is necessary for evaluating respiratory status and acid-base abnormalities, particularly in the comatose or seizure patient. Hydrofluoric acid dermal burns. But poisons can also enter the body in other ways: By breathing, Through the skin, By IV injection Hantson P. Formate kinetics in methanol poisoning. Poisoning should be suspected in any patient who presents with multisystem disturbance until proven otherwise. The hormone may also provide therapeutic benefit in hypotension after calcium channel blocker overdose.18 Glucagon is given in an initial dose of 1 to 10 mg (50 to 150 g/kg in children). Clinical situations in which endotracheal intubation may be necessary in poisoned patients are numerous (Box 2A-1 In select cases, specific agents should be used to assist in management (Table 2A-8 Urfeya Mirza Basics of poisoning and drug overdose managent SourabHiremath The differences between the airway of the child and that of the adult have important implications for endotracheal intubation. Olmedo R, Nelson L, Chu J, Hoffman RS. Being colloid rather than crystalloid in nature, these fluids in theory maintain intravascular volume better than saline solutions do. Geeky Medics accepts no liability for loss of any kind incurred as a result of reliance upon the information provided in this video. Ipecac syrup administration will not adversely affect more definitive treatment that might be provided at a hospital. Perry J, Lee J, Wells G. Rocuronium versus succinylcholine for rapid sequence induction intubation. Begin by asking the patient if they have pain anywhere, which may be helpful to guide your assessment. Acute propoxyphene hydrochloride intoxication. Ho PC, Dweik R, Cohen MC. The disposition of the patient with intoxication may involve medical and psychiatric care as well as social follow-up. Current concepts: peritoneal dialysis. <> Pediatric carbamazepine intoxication. Some effects are not seen until later, such as hypertension following phencyclidine ingestion, hemorrhagic colitis following mercury ingestion, and disseminated intravascular coagulation following snakebite. <>/XObject<>/ProcSet[/PDF/Text/ImageB/ImageC/ImageI] >>/Annots[ 9 0 R] /MediaBox[ 0 0 720 540] /Contents 4 0 R/Group<>/Tabs/S/StructParents 0>> 1-Adrenergic receptor agonists produce increased heart rate and contractility, whereas 2-adrenergic receptor agonists promote generalized smooth muscle relaxation (including bronchial and vascular). Life-threatening ingestion of substance adsorbable by activated charcoal, Evidence or anticipation of ongoing absorption (rising drug levels later than expected, sustained-release preparations), Anticipation or presence of decreased mental status, anticipation or presence of seizures, or decreased gag reflex without a cuffed endotracheal tube in place for airway protection, Contraindicated if recent abdominal surgery, Dialyzable toxin low volume of distribution low protein binding molecular weight < 10,000 daltons, Hemodynamically unstable patient or hemodialysis not available or impractical (small children), Radiocontrast-induced acute renal failure, Hemodynamically stable enough for dialysis (relative), Underlying contraindication to anticoagulation (relative), High toxin clearance critical to patient survival, Drug excretion impaired by hepatic or renal failure, Focal peritonitis, fecal fistula, colostomy, undiagnosed abdominal disease, extensive adhesions, recent abdominal surgery with prosthetic material, vascular anastomosis or open wound (relative).

A number of factors determine the suitability of use of HD or HP as extracorporeal methods of removal of a given toxicant. sharing sensitive information, make sure youre on a federal Older children and adults should receive 30 mL ipecac followed by 200 to 300 mL of water. Charcoal is likewise contraindicated in any patient in whom the airway protection is not assured. Graw RG, Clarke RR. Poisoning with Alcohols 447 95. Therefore, in patients who are undergoing RSI after exposure to these agents, atropine should either be administered prophylactically or kept immediately available should emergency administration become necessary. Lacomis D. Case of the month. In patients with abdominal pain, a surgical abdomen must be ruled out. 4. In the case of toxicants, diffusion into the dialysate is the primary end point, although amelioration of acid-base and electrolyte conditions is often an important additional goal. Chan JC, Campbell RA. The CDC Advisory Committee on Childhood Lead Poisoning Prevention issued case management guidelines for children with lead poisoning, which should be consulted as needed. For magnesium citrate, the dose is 4 to 6 mL/kg in children and 300 to 480 mL in adults. Pond SM, Olson KR, Osterloh JD, Tong TG. The patient required packed red blood cells, platelets, and fibrin transfusions, developing oliguric-anuric renal failure that required 23 days of HD over a period of several weeks. Despite its shortcomings, this study suggests the potential for improved healing using Diphoterine in alkaline eye burns and warrants further investigation. Hyperbaric oxygen can provide oxygen at pressures greater than normal atmospheric pressure, which is given as 1 atmosphere (atm) or 760 mm Hg.
