Epidural and spinal blocks are two types of anesthesia used to provide pain relief during medical procedures. An epidural block is a type of regional anesthesia that is injected into a specific area near the spine to block pain signals from reaching the brain. A spinal block is a type of regional anesthesia that is injected directly into the spinal fluid to block pain signals from reaching the brain. Both epidural and spinal blocks provide pain relief, but they have different effects.
Epidural blocks are typically used for procedures that require a longer duration of anesthesia, such as during labor and delivery. The block is often used to provide pain relief for several hours. Spinal blocks are typically used for shorter procedures, such as surgery, as the block wears off quickly. The effects of a spinal block typically last for only a few minutes. Additionally, epidural blocks provide more localized pain relief, while spinal blocks provide more widespread pain relief.
