Key Finding
Multimodal, opioid-sparing analgesia combining systemic non-opioids, local anesthetic blocks, and adjuvants including acupuncture appears most effective for postcraniotomy pain, though high-quality comparative evidence for non-pharmacologic therapies remains limited.
Researchers reviewed the best ways to manage pain after brain surgery, looking at both medication and non-drug approaches published between 2016 and 2024. Brain surgery pain is especially difficult to treat because each person experiences pain differently and the surgical area is delicate. The study examined many treatments including standard pain medications, nerve blocks using local anesthetics, and alternative therapies like acupuncture, electrical nerve stimulation (TENS), and cognitive behavioral therapy. What they found was that combining multiple pain relief methods works better than relying on opioid painkillers alone. Regular pain medications like acetaminophen and NSAIDs helped reduce pain in the first 12-24 hours after surgery. Nerve blocks provided short-term relief. Some medications called gabapentinoids reduced the need for opioids but made patients dizzy and sleepy. For non-drug approaches, the evidence was more limited but showed promise. Acupuncture, along with TENS therapy, cognitive behavioral therapy, and brain stimulation techniques, appeared helpful especially for longer-lasting pain or nerve-related discomfort after brain surgery. However, the researchers noted that studies on these non-drug treatments varied widely in quality and design, making it hard to draw firm conclusions. What this means for patients: If you're having brain surgery, ask your medical team about a comprehensive pain management plan that includes multiple approaches rather than just opioid medications. Acupuncture and other complementary therapies may offer additional relief, particularly as you recover. If considering acupuncture for post-surgical pain management, seek a licensed acupuncturist experienced in working with surgical patients.
This narrative review synthesized evidence from 2016-2024 on postoperative analgesia following intracranial surgery, searching PubMed/MEDLINE, EMBASE, Scopus, Web of Science, Cochrane CENTRAL, and Google Scholar. The review prioritized RCTs, systematic reviews, meta-analyses, and high-quality observational studies. Findings support multimodal, opioid-sparing protocols combining systemic non-opioid analgesics (NSAIDs, acetaminophen) with local anesthetic scalp blocks (ropivacaine). NSAIDs and acetaminophen provided modest pain reduction for 12-24 hours post-craniotomy. Gabapentinoids decreased opioid consumption but increased adverse effects (dizziness, somnolence). Dexmedetomidine showed inconsistent superiority. Regarding non-pharmacologic modalities, acupuncture, TENS, rTMS, and CBT demonstrated potential for longer-term and neuropathic pain management, though evidence quality was heterogeneous and limited. Clinical takeaway: Acupuncture may serve as an adjunctive modality in multimodal postcraniotomy pain protocols, particularly for persistent or neuropathic symptoms, though standardized comparative trials are needed to establish optimal protocols and determine effect sizes.
