Abstract
A surgical technique is described for preparation of chronic cervical vagal loops in ponies. Vagal blockade was induced by circulating methanol (-2.degree. C) through coils which enclosed the loops. Vagal blockade increased tidal volume, heart rate and systemic blood pressure and decreased respiratory rate. Atropine, given at a dose of 0.04 mg/kg i.v., increased heart rate and systemic pressure but did not alter respiratory variables, indicating that vagal cooling caused both afferent and efferent blockade. The effects of vagal blockade were rapidly reversed when refrigerated coils were removed.This publication has 7 references indexed in Scilit:
