What are the other Names for the Procedure?
- Peripheral Nerve Stimulation for Neuropathic Pain
- Stimulation of Peripheral Nerve for Neuropathic Pain
What is the Peripheral Nerve Stimulation surgical procedure?
- Peripheral Nerve Stimulation procedure involves placing electrodes under the skin in the area of the nerves that may be causing pain symptoms
- Delivery of small electrical impulses to the nerves blocks the pain signals, thereby providing symptomatic relief
What part of the Body does the Procedure involve?
Peripheral Nerve Stimulation involves the tissue under the skin corresponding to the area supplied by the ‘pain-causing’ nerve. This usually involves the tissue under the skin of the belly, upper chest, or buttock.
Why is the Peripheral Nerve Stimulation surgical procedure Performed?
Peripheral Nerve Stimulation procedure is performed to provide relief from neuropathic pain (pain arising from problematic nerve signals).
What are some Alternative Choices for the Procedure?
Medication to control pain and alternative kinds of therapy, such as acupuncture, may be used to relieve pain.
What are the Recent Advances in the Procedure?
There are no recent advances in the procedure.
What is the Cost of performing the Peripheral Nerve Stimulation surgical procedure?
The cost of Peripheral Nerve Stimulation procedure depends on a variety of factors, such as the type of your health insurance, annual deductibles, co-pay requirements, out-of-network and in-network of your healthcare providers and healthcare facilities.
In many cases, an estimate may be provided before the procedure. The final amount depends upon the findings during the surgery/procedure and post-operative care that is necessary.
When do you need a Second Opinion, prior to the Procedure?
- It is normal for a patient to feel uncomfortable and confused by the information regarding a Peripheral Nerve Stimulation procedure and on what needs to be done
- If the patient needs further reassurance or a second opinion, a physician will almost always assist and also recommend another physician, if required
- Also, if the procedure involves multiple surgeries or has many alternatives, the patient may take a second opinion to understand and choose the best one. They can also choose to approach another physician independently

Prior to Peripheral Nerve Stimulation surgical procedure:
How is the Peripheral Nerve Stimulation surgical procedure Performed?
The Peripheral Nerve Stimulation procedure is performed in two stages and may be carried out under local anesthesia with sedation.
- The surgeon may implant an electrode along the culprit nerve causing pain
- This may be a temporary electrode to first check if Peripheral Nerve Stimulation helps in pain relief
- The temporary electrode is connected to an external stimulator that can be adjusted
- If this provides pain relief, the surgeon may then implant permanent electrodes under the skin in the same area
- The leads from the permanent electrodes are connected to a stimulator device that is implanted under the skin of the belly, the upper part of chest, or the upper part of the buttock
Where is the Procedure Performed?
A Peripheral Nerve Stimulation is performed in a hospital, usually on an outpatient basis.
Who Performs the Procedure?
The procedure is performed by the following medical personnel, with or without assistance from an anesthesiologist:
- A neurosurgeon
How long will the Procedure take?
The procedure may take an hour or so to perform.
What do you need to tell your Physician before the Procedure?
It is very important to provide the following information to your healthcare provider. This enables your healthcare provider in assessing the risks for the Peripheral Nerve Stimulation procedure and helps avoid unnecessary complications.
- Provide a complete list of medications you are currently taking to your physician. This information is useful for a variety of reasons. For example, it can help your healthcare provider prevent complications due to a drug interaction
- If you are allergic to any specific medication or food items
- If you are taking blood thinners such as aspirin, warfarin, herbal supplements, or any other such medications
- If you or your family members have a history of bleeding disorders, or if there is a tendency to bleed more than normal
- If you have diabetes, high blood pressure, chest pains, or have previously suffered from a heart attack
- If you have ever been diagnosed with blood clots in your leg (deep vein thrombosis) or lung (embolism of lung)
- If you have a history of frequent bone fractures (this may affect bone-healing if bones are involved as part of your procedure)
- A list of all previous surgical procedures you have undergone, for example: Removal of appendix, gallbladder, or any other part, of your body; surgical repair of any body part, such as hernia repair, perforation of bowel wall, etc.
What Preparations are needed, prior to the Procedure?
- The physician may evaluate the individual’s medical history to gain a comprehensive knowledge of the overall health status of the patient including information related to the medications that are currently being taken
- Some medications increase a person’s chances of bleeding and it may be recommended to discontinue them for a period of time before the procedure is performed
- Blood tests may be performed to determine if there is a bleeding tendency or any other medical conditions that prevents the person from undergoing the procedure
- Inform the physician if you are allergic to any local anesthetics, lidocaine, etc.
- Avoid application of any cosmetics, deodorant, or topical medicines on the area prior to the procedure
- It is advisable to quit smoking and the use of any nicotine based products for a while before the surgery
- Consumption of alcoholic drinks must also be avoided for a period of time, as instructed
- The patient must avoid eating or drinking at least 8 hours prior to the surgical procedure, depending on when the procedure is arranged
- For individuals suffering from diabetes, it is important that the blood sugar stays within the normal range; if not, their diabetologist may have to control blood sugar by recommending insulin and/or a combination of oral medicines
What is the Consent Process before the Procedure?
A physician will request your consent for Peripheral Nerve Stimulation for Neuropathic Pain procedure using an Informed Consent Form.
Consent for the Procedure: A “consent” is your approval to undergo a procedure. A consent form is signed after the risks and benefits of the procedure, and alternative treatment options, are discussed. This process is called informed consent.
You must sign the forms only after you are totally satisfied by the answers to your questions. In case of minors and individuals unable to personally give their consent, the individual’s legal guardian or next of kin, shall give their consent for the procedure.
