For simple Lumbar epidural I uses air syringe & keep women sitting, especially obese.
But lateral position appropriate as well.
Saline in syringe  [european school] & work good if any complication anticipated.
Also I uses saline to lubricate pathway for catheter, after proper localisation of needle in peridural space.

Don't give dipyrone, antipiretic & analgetic, in PostOp ;D
