1) ESTABLISH CLEAR AIRWAY & TISSUE OXYGENATION BY ASPIRATION OF SECRETIONS & IF NECESSARY, BY ASSISTED PULMONARY VENTILATION WITH OXYGEN. IMPROVE TISSUE OXYGENATION AS MUCH AS POSSIBLE BEFORE ADMINISTERING ATROPINE TO MINIMIZE THE RISK OF VENTRICULAR FIBRILLATION. /CARBAMATES, CHOLINESTERASE INHIBITORS/

2) ADMIN ATROPINE SULFATE IV, OR IM IF IV INJECTION IS NOT POSSIBLE... IN MODERATELY SEVERE POISONING: ADULT DOSAGE, INCLUDING CHILDREN OVER 12 YR: 0.4-2.0 MG REPEATED EVERY 15 MIN UNTIL ATROPINIZATION IS ACHIEVED (TACHYCARDIA, FLUSHING, DRY MOUTH, MYDRIASIS). MAINTAIN ATROPINIZATION BY REPEATED DOSES FOR 2-12 HR, OR LONGER, DEPENDING ON SEVERITY OF POISONING... DOSAGE FOR CHILDREN UNDER 12 YEARS: 0.05 MG/KG BODY WT REPEATED EVERY 15 MIN UNTIL ATROPINIZATION IS ACHIEVED. MAINTAIN ATROPINIZATION WITH REPEATED DOSAGE OF 0.02-0.05 MG/KG. SEVERELY POISONED INDIVIDUALS MAY EXHIBIT REMARKABLE TOLERANCE TO ATROPINE; TWICE THE DOSES SUGGESTED ABOVE MAY BE NEEDED... /CARBAMATES, CHOLINESTERASE INHIBITORS/

3. PRALIDOXIME (PROTOPAM-AYERST, 2-PAM) IS OF DOUBTFUL VALUE IN POISONINGS BY CARBAMATE INHIBITORS OF CHOLINESTERASE. ATROPINE ALONE IS ALMOST ALWAYS AN ADEQUATE ANTIDOTE. PRALIDOXIME IS PROBABLY CONTRAINDICATED IN POISONINGS BY CARBARYL, SPECIFICALLY. IF VICTIM OF CARBAMATE POISONING EXHIBITS SEVERE MUSCLE WEAKNESS &/OR RESPIRATORY DEPRESSION, OR IF POISONING INVOLVES A COMBINATION OF CARBAMATE & ORGANOPHOSPHATE, A DILUTE SOLUTION OF PRALIDOXIME (TOTAL DOSE IN 250 ML 5% GLUCOSE SOLN) MAY BE GIVEN CAUTIOUSLY IV. THE INFUSION SHOULD BE TERMINATED IF PATIENT'S CONDITION WORSENS. PRALIDOXIME DOSAGE: ADULTS, 1.0 G; FOR CHILDREN UNDER 12 YR, 20-50 MG/KG. 4. OBSERVE TREATED PATIENTS CLOSELY AT LEAST 24 HR TO INSURE THAT SYMPTOMS (POSSIBLY PULMONARY EDEMA) DO NOT RECUR AS ATROPINIZATION WEARS OFF. IN VERY SEVERE POISONINGS, METABOLIC DISPOSITION OF TOXICANT MAY REQUIRE SEVERAL HR OR DAYS DURING WHICH ATROPINIZATION MUST BE MAINTAINED. /CARBAMATES, CHOLINESTERASE INHIBITORS/

5. BATHE & SHAMPOO VICTIM WITH SOAP & WATER IF THERE IS ANY CHANCE THAT SKIN & HAIR ARE CONTAMINATED. 6. IF PESTICIDE HAS BEEN INGESTED IN QUANTITY SUFFICIENT TO CAUSE POISONING, EMPTY THE STOMACH & INTESTINE. A. IF VICTIM IS ALERT & RESPIRATION IS NOT DEPRESSED, GIVE SYRUP OF IPECAC, FOLLOWED BY 1-2 GLASSES OF WATER TO INDUCE VOMITING; ADULTS (INCLUDING CHILDREN OVER 12), 30 ML; CHILDREN (UNDER 12 YR), 15 ML. CAUTION: OBSERVE VICTIM CLOSELY AFTER ADMIN IPECAC, IF CONSCIOUSNESS LEVEL DECLINES, OR IF VOMITING HAS NOT OCCURRED IN 15 MIN, PROCEED IMMEDIATELY TO INTUBATE THE STOMACH. FOLLOWING EMESIS, HAVE VICTIM DRINK A SUSPENSION OF /PRC: 30 G ACTIVATED CHARCOAL IN 3-4 OZ OF WATER (CHILDREN), 100 G IN 8-10 OZ OF WATER (ADULTS)/...TO BIND TOXICANT REMAINING IN THE GI TRACT. /CARBAMATES, CHOLINESTERASE INHIBITORS/
