A parasympathetic block refers to the inhibition of the parasympathetic nervous system's functions, often achieved through pharmacological means or nerve blocks. This can lead to reduced secretions, decreased gastrointestinal motility, and dilation of the pupils, among other effects. It is commonly used in medical procedures to manage specific symptoms or during surgeries to counteract excessive parasympathetic activity. Such blocks can be beneficial in treating conditions like bradycardia or excessive salivation.
