<P> Atropine has also been used in an effort to prevent a low heart rate during intubation of children; however, evidence does not support this use . </P> <P> Atropine's actions on the parasympathetic nervous system inhibit salivary and mucus glands . The drug may also inhibit sweating via the sympathetic nervous system . This can be useful in treating hyperhidrosis, and can prevent the death rattle of dying patients . Even though atropine has not been officially indicated for either of these purposes by the FDA, it has been used by physicians for these purposes . </P> <P> Atropine is not an actual antidote for organophosphate poisoning . However, by blocking the action of acetylcholine at muscarinic receptors, atropine also serves as a treatment for poisoning by organophosphate insecticides and nerve gases, such as tabun (GA), sarin (GB), soman (GD) and VX . Troops who are likely to be attacked with chemical weapons often carry autoinjectors with atropine and obidoxime, for rapid injection into the muscles of the thigh . In a developed case of nerve - gas poisoning, maximum atropinization is desirable . Atropine is often used in conjunction with pralidoxime chloride . </P> <P> Atropine is given as a treatment for SLUDGE syndrome (salivation, lacrimation, urination, diaphoresis, gastrointestinal motility, emesis) symptoms caused by organophosphate poisoning . Another mnemonic is DUMBBELSS, which stands for diarrhea, urination, miosis, bradycardia, bronchoconstriction, excitation (as of muscle in the form of fasciculations and CNS), lacrimation, salivation, and sweating (only sympathetic innervation using muscarinic receptors). </P>
