<prompt> True about Epidural anesthesia:Effects sta immediatelyCI in coagulopathiesGiven in subarachnoid spaceAll  <response>: B i.e. CI in coagulopathies Epidural anaesthesia is given in epidural spaceQ extending from foramen magnum to sacral hiatus not in subarachnoid spaceQ which is used for intrathecal - spinal anesthesia. In comparison to spinal anesthesia, the volume of drug given is larger, onset on effect is delayed 5-20 min and duration of action is prolongedQ in epidural anesthesia. Both epidural spinal anesthesia block sympathetic outflow T12 - L2. This produces dilation of resistance and capacitance vessels decreasing venous return causing hypo-tensionQ. However, this fall is sudden profound in spinal anesthesia, whereas slower profound in epidural anesthesia. Centrineuraxial spinal epidural anesthesia is contraindicated in coagulopathy, blood dyscariasis, full anticoagulant oral warfarin, LMVV heparin fibrinolytic therapy but can be given to patients on antiplatelet agents like aspirin NSAIDs.
