Transcript

  • 1. ELIMINATION ENHANCEMENT
  • 2. ELIMINATION • It is defined as the act of removing or getting rid of bodily discharged waste matter. • The elimination systems in our body,eliminates about two pounds of material per day in the normal healthy adult. • If any one of these channels become overloaded or clogged and slowed down, there will be an accumulation of toxic material in the body tissues.
  • 3. ELIMINATION SYSTEMS • There are 5 elimination systems in body, THE BOWL(colon) KIDNEYS LUNGS SKIN LIVER • The lymph system works with these five systems by serving as a "garbage collector" to carry metabolic by-products and accumulated cellular waste from tissues to the elimination organs.
  • 4. ELIMINATION ENHANCEMENT • Accidental and intentional poisonings or drug overdoses constitute a significant source of aggregate morbidity, mortality, and health care expenditures. • Management of the poisoned patient begins with a thorough evaluation, identification of the agent(s) involved, assessment of severity, and prediction of toxicity. • Therapy involves the provision of supportive care, prevention of poison absorption, the administration of antidotes and enhancement of elimination of the poison.
  • 5. METHODS OF ENHANCEMENT • Multiple dose activated charcoal • Saline diuresis • Extracorporial methods-dialysis hemo perfusion hemo filtration plasmapheresis exchange transfusion
  • 6. Other therapies: • Hyperbaric oxygen • Chelation therapy • Cerebrospinal fluid removal • Immunological therapy-specific antibody toxin binding.
  • 7. Multiple dose activated charcoal • Charcoal slurry along the entire intestinal tract • Large surface area for adsorption of drug diffusing across intestinal epithelium from capillaries • MDAC can also enhance elimination of absorbed toxins by interrupting enterohepatic and enteroenteric recirculation and by promoting passive diffusion of drugs from the intestine.
  • 8. Some Agents for which MDAC may enhance elimination are: • Dapsone • Amitriptaline • Diazepam • Methotrexate • Salicylate • Valproate
  • 9. Saline diuresis • The urinary excretion of some drugs can be enhanced by increasing the urine output and, more importantly, altering the urine pH. • urinary acidification (urine pH below 5.5) with ammonium chloride or ascorbic acid will increase the excretion of weak bases. • For drugs that are weak acids (eg, salicylates, phenobarbital), raising the urine pH to 7.5 to 8.0 .
  • 10. Some Agents • Forced diuresis -barium chromium iodide calcium potassium lithium alkaline diuresis -salicylates barbiturates sulfonamides
  • 11. hemodialysis • Can be arteriovenous or veno-venous (double- lumen catheter) • Requires anticoagulation • Best if drug is: ▫ water-soluble ▫ small (MW <500) ▫ not highly protein bound • Also good for correcting fluid & electrolyte abnormalities.
  • 12. Some Agents • Barbiturates • Alcohols • Lithium • Salicylates • Atenolol • Theophylline etc
  • 13. Peritoneal dialysis • Tubes are inserted into the peritoneal cavity. electrolytes and fluids were sent and waste matter is collected out side. • Theoretically useful if drug is: ▫ water soluble ▫ small (MW <500) ▫ not highly protein bound • Rarely performed unless it’s the only available method.
  • 14. hemoperfusion • Hemoperfusion refers to the circulation of blood through an extracorporeal circuit containing an adsorbent such as activated charcoal or polystyrene resin.
  • 15. Some agents • Phenobarbitol • Sedatives • Phynitoin • Chloramphenicol • Carbamazepine • Caffeine.
  • 16. hemofiltration • Blood that enters the hemofiltration circuit passes through filters with large pores, and an ultrafiltrate forms which drags solutes with molecular weights up to 50,000 daltons . • Cells and solutes larger than the pore size remain in the blood and return to the circulation. Plasma moves across semipermeable membrane under hydrostatic pressure • No dialysate.
  • 17. Some agents • Aminoglycosides, • Vancomycin, and • Metal chelate complexes.
  • 18. plasmapheresis • It is the removal, treatment, and return of (components of) blood plasma from blood circulation. It is thus an extracorporeal therapy (a medical procedure performed outside the body). • The method is also used to collect plasma, which is frozen to preserve it for eventual use in the manufacture of a variety of medications.
  • 19. Exchange transfusion • Exchange transfusion refers to the removal of a quantity of blood from a poisoned patient and its replacement with an identical quantity of whole blood • The process is usually repeated two to three times. • for methemoglobinemia, sulfhemoglobinemia (eg, secondary to hydrogen sulfide exposure), or in neonatal drug toxicity.
  • 20. Hyperbaric oxygen • Hyperbaric oxygen therapy uses a special chamber, sometimes called a pressure chamber, to increase the amount of oxygen in the blood. • The air pressure inside a hyperbaric oxygen chamber is about two and a half times greater than the normal pressure in the atmosphere. This helps your blood carry more oxygen to organs and tissues in your body.
  • 21. Chelation therapy • Chelation therapy is the administration of chelating agents to remove heavy metals from the body. • Heavy metals include- lead, arsenic or mercury. • chelating agents include dimercaptosuccinic acid, and alpha lipoic acid.
  • 22. Cerebrospinal fluid removal • It is performed in order to collect a sample of cerebrospinal fluid containing poision.
  • 23. Immunological therapy • The use of antibodies in the diagnosis and treatment of drug poisoning is becoming an important aspect of emergency medicine. • Digoxin-specific antibodies selectively inhibit the pharmacologic and toxic effects of the digitalis glycosides.
