If the shakes/shivers occur post epidural I have had success if I can get the patient to yawn. Shivers/shakes and yawns are both carried on the sympathetic or parasympathetic I can't remember which, but forcing one to happen causes the other to stop, at least for a while. It is usually best to get everyone in the room to yawn as you know how contagious yawning is! If it is 7 cm shaking in an unmedicated pt,

good luck getting them to yawn.
