| What are adverse effects of an epidural | Maternal hypotension, bladder distention, prolonged second stage of labor, migration of the epidural catheter and fever. |
| What are contraindications of spinal blocks? | Coagulation defects, uncorrected hypovolemia, infection, allergy, or prior spinal surgery |
