Nerve Block Injections
Nerve block injections used for pain management
Nerve block injections are used to treat chronic pain when other treatment causes bad side effects. It is mainly used to try to diagnose what conditions are causing back or neck pain. Nerve block injections are used for pain management by numbing the nerves and its surrounding areas. Patients will be asked which injection cases the back pain to decrease, and therefore be chosen for an epidural injection for further head to toe pain management.
How are nerve block injections performed?
Nerve blocks are performed as anesthesia during surgery or other medical procedures. It is done by injecting a substance into or around a nerve or spine with alcohol or phenol. After a nerve block injection patient usually experience numbness with near complete pain relief. After several hours, the numbness will wear off and patients are to return to normal routine.
What are the different types of nerve block injections for pain relief?
Therapeutic Nerve Block Injections
Therapeutic nerve blocks are used to treat chronic and painful conditions because it contains local anesthetic that can be used to control acute pain, especially in self- limiting disorder. This type of nerve block help patients maintains an outpatient treatment status. The patient can also participate in rehabilitation programs that includes physical therapy to avoid or delay surgical intervention.
Sympathetic nerve block
A sympathetic nerve block is one that is performed to determine if there is damage to the sympathetic nerve chain. This is a network of nerves extending the length of the spine. These nerves control some of the involuntary functions of the body, such as opening and narrowing blood vessels.
Diagnostic Nerve Block Injections
Diagnostic nerve blocks are used to determine sources of pain. These blocks typically contain an anesthetic with known duration of relief. It involves numbing a specific group of nerves that may be involved in carrying a patient’s pain. Diagnostic nerve blocks treatment will include a patient’s reaction to the nerve groups after the patient is assessed for any change in pain symptoms. If nerve groups were numb and pains alleviate, then patients will know that results are successful.
Prognostic Nerve Block Injections
Prognostic nerve blocks predict the outcomes of given treatments. These blocks may also help the pain doctors to decide whether the patient should proceed with surgery or ablative procedures. Prognostic blocks are intended to provide information that may or may not affect the outcome of the patients results.
Preemptive Nerve Block Injections
Preemptive nerve blocks can be used to avoid surgery if patients wish to prolong their wait time while participating in physical therapy programs. This type of nerve blocks is meant to prevent subsequent pain from a procedure that can cause problems including phantom limb pain.
When are nerve blocks injections for pain relief used?
Nerve block injections for pain relief are used for various purposes:
- When treating painful conditions
- To predict how pain will respond
- For short term pain relief
- Used as anesthesia during smaller procedures
- When determining the source of pain
How long does a nerve block injection last?
The duration of time that a nerve block injection can last will depend on the type of nerve block injections performed and the type of numbing medication used. Nerve block injections usually lasts for 6 to 8 hours when used for hand surgery treatments. If used for knee replacement, nerve block injections can last for 12 to 24 hours since medication from nerve block injections are delivered throughout the treated areas and are placed next to the nerve group.
