We evaluated the effect of mexiletine and gabapentin on the acute and chronic pain after breast surgery for cancer. Both drugs reduced the postoperative analgesic requirements, and particularly, gabapentin reduced pain after movement. Neuropathic pain after breast cancer treatment and its impact on sleep quality one year after cancer diagnosis. Fontes F, Gonçalves M, Pereira S, Lunet N. Breast. 2017;33:125–131. doi: 10.1016/j.breast.2017.03.013. [Google Scholar] 55. Gabapentin: Decreases opioid consumption post-mastectomy, and reduced pain 24 hours post-surgery. Pregabalin: Reduced PMPS frequency when administered starting the day of the surgery. Levetiracetam: No significant difference in pain intensity between levetiracetam and placebo in PMPS treatment. Two placebo-controlled studies have investigated the effect of systemic dexamethasone on postoperative pain, nausea and vomiting after conservative oncologic breast surgery and mastectomy 11, 12. Both studies reported similar results. In particular, patients receiving i.v. dexamethasone had significantly less pain up to 24 h after surgery.

Modified radical mastectomy combined variably with chemotherapy or radiotherapy is currently the treatment of choice for breast cancer. Acute and chronic pain is a common The reported prevalence of post-mastectomy pain syndrome (PMPS) ranges from less than 10% to more than 50% of patients after mastectomy. 1–4 This chronic pain is believed to be related to injury of the sensory nerves to the breast, chest, and upper arm/axilla. In the past, when concern was predominantly on patient survival, this pain was Some non-opioid pain medications, such as gabapentin (Neurontin), pregabalin (Lyrica) and duloxetine (Cymbalta), are specific for nerve pain. If the lidocaine patch doesn’t relieve your pain, ask your health care provider whether any of these drugs might help. However, the authors 2 found that the evidence demonstrates benefit of single-use gabapentin with regard to pain relief and opioid-sparing effect up to 24 h after surgery, whilst pregabalin only showed benefit in PACU. tematic computer-based search was conducted in PubMed, Embase, Web of Science, Cochrane Library, and Google databases. RCTs comparing gabapentin with placebo in patients undergoing breast cancer surgery were retrieved. The primary endpoint was the visual analog scale (VAS) after surgery and 24 hours after surgery and total morphine consumption. The secondary outcomes were incidence of chronic Wijayasinghe N, Duriaud HM, Kehlet H, et al. Ultrasound guided intercostobrachial nerve blockade in patients with persistent pain after breast cancer surgery: a pilot study. Pain Physician. 2016;19:E309–E318. [Google Scholar] 38. Dessy LA, Maruccia M, Mazzocchi M, et al. Treatment of post mastectomy pain syndrome after mastopexy with We defined new postoperative gabapentin as fills for 7 days before surgery until 7 days after discharge. We excluded patients whose discharge disposition was hospice or death. The primary outcome was prolonged use of gabapentin, defined as a fill>90 days after discharge. Post-mastectomy pain syndrome is a chronic neuropathic pain that usually manifests as continuous pain in the arm, axilla, chest wall, and breast region. [3] Pain is most likely to start after surgery, [3] although adjuvant therapy, such as chemotherapy or radiation therapy, may sometimes cause new symptoms to appear. [4] Pain control (analgesia) — Gabapentin is a nerve medication that reduces pain when taken the night before surgery. Some pathways recommend continuing this medication at home for several weeks as it may also help reduce chronic pain from mastectomy. Gabapentin would seem to be the ideal analgesic for managing acute and chronic pain following breast cancer surgery since it possesses antihyperalgesic and antiallodynic effects in the setting of peripheral tissue injury . Peripheral neve surgery may be an option for patients experiencing chronic post-mastectomy pain. Visit the peripheral nerve surgery page or contact our clinic at 734-998-6022 to learn more about this option. Nerve Injury Contributes to Post-Mastectomy Pain Peripheral nerve injury during surgery can lead to cortical changes, known as central sensitization, involved in persistent post-surgical neuropathic pain. 37 Gabapentin, amitriptyline, and venlafaxine were found to offer pain relief for breast cancer patients with chronic pain, by targeting centralized pain pathways. How we treat nerve pain after a mastectomy. We generally use some combination of oral medication and topical cream to relieve nerve pain after a mastectomy. These medications are designed specifically to address nerve pain. We consider nerve blocks after surgery as a last resort. Managing post-mastectomy pain syndrome (PMPS) PMPS can keep you from being able to use your arm like you used to, but there are options to manage it. Treatments. Gabapentin – Medicine used to treat nerve pain; Venlafaxine – Medicine used to treat symptoms that you might have with nerve pain, such as hot flashes; Surgical- Used to treat scars Peripheral nerve injury during surgery can lead to cortical changes, known as central sensitization, involved in persistent post-surgical neuropathic pain. 37 Gabapentin, amitriptyline, and venlafaxine were found to offer pain relief for breast cancer patients with chronic pain, by targeting centralized pain pathways. Ask your doctor if you are a candidate for a nerve block during your mastectomy. This can lessen the amount of pain medications you need post operatively. Commonly prescribed medications after surgery: Tylenol, NSAIDs (i.e. Advil), Opioids (i.e. oxycodone).
