Labor and delivery: Pain medications

Spinal block

A spinal block is typically used to block pain during a C-section. However, a spinal block can be used to relieve pain if delivery is expected shortly or if forceps or vacuum extraction is needed.

During a spinal block, the medication is injected into the fluid below the spinal cord in the lower back. It takes effect quickly. It can provide only a couple of hours of pain relief. A spinal block given during epidural placement is called a combined spinal-epidural block.

Pros

A spinal block provides complete pain relief in the lower body for about an hour or two. You'll remain awake and alert.

Cons

A spinal block might decrease blood pressure. Infrequently, this can slow the baby's heart rate. Side effects include itching or back soreness after delivery. A rare side effect is a bad headache.
