Atropine only blocks muscarinic acetylcholine receptors (a different receptor class than the nicotinic receptors at the neuromuscular junction), so atropine will not improve the muscle strength and ability to breathe in someone with cholinergic crisis. Such a patient will require neuromuscular blocking drugs and mechanical ventilation until the crisis resolves on its own. See also
Physostigmine

Mechanism
The term compensatory is largely misleading, as it indicates that there is a compensatory mechanism that takes effect after sympathectomy, in which the body redirects the sweating from the palms or face to other areas of the body. Sweating after sympathetic surgery is a reflex cycle between the sympathetic system and the anterior portion of the hypothalamus. Reflex sweating will not happen if hand sweating can be stopped without interrupting sympathetic tone to the human brain.Compensatory hyperhidrosis is aberrant sympathetic nervous system functioning. The only study evaluating the total body sweat prior and shortly after sympathectomy concluded that patients produce more sweat after the surgery, just not so much in the areas treated by the surgery. Epidemiology
Of people that have a sympathectomy, it is impossible to predict who will end up with a more severe version of this disorder, as there is no link to gender, age or weight. There is no test or screening process that would enable doctors to predict who is more susceptible. == References ==
