Summary of interventions to manage pain in patients with GBS.
| Author(s) | GBS subtype | Treatment type | Agents/Approach | Effectiveness/Notes |
|---|---|---|---|---|
| Peña et al./2015 [11] | Not specified | Neuropathic agents | Carbamazepine | Reduced pain and need for rescue opioids like fentanyl/pethidine |
| Pandey et al./2005 [15] | Not specified | Neuropathic agents | Gabapentin, carbamazepine | Gabapentin is more effective than carbamazepine, reduces fentanyl use significantly |
| Pandey et al./2002 [16] | Not specified | Neuropathic agents, opioids | Gabapentin, fentanyl | Less fentanyl consumption during gabapentin periods than during placebo periods |
| Khatri & Pearlstein/1997 [14] | Not specified | Neuropathic agents | Gabapentin (100 mg TID; 300 mg BID) | Effective pain relief, well-tolerated; recommended in GBS pain management |
| Ritter et al./2023 [13] | MFS secondary to SARS-CoV-2 infection | Antidepressants, neuropathic agents | Amitriptyline, pregabalin, gabapentin | Gabapentinoids were ineffective; pain resolved with amitriptyline, relapse of pain on taper |
| Liu et al./2015 [3] | Not specified | Neuropathic agents | Gabapentin, carbamazepine | Both were effective vs. placebo, but no definitive recommendation due to study limitations |
| Tripathi & Kaushik/2000 [17] | Not specified | Neuropathic agents | Carbamazepine | Lower pain scores and reduced opioid (pethidine) needs; carbamazepine is recommended for ICU patients |
| McDouall & Tasker/2004 [18] | Not specified | Neuropathic agents vs. opioids | Carbamazepine | Argued that carbamazepine is as effective for neuropathic pain as opioids, with fewer side effects (sedation, ventilation delay) |
| Ali & Hutfluss/1992 [19] | Not specified | Epidural analgesia | Epidural bupivacaine + fentanyl | Significant visual analog scale reduction (9 → 2) and improved mobility |
| Morgenlander et al./1990 [20] | Not specified | Topical neuropathic agent | Capsaicin 0.075% q6h | Provided relief after failure of multiple agents; recurrence of pain on discontinuation |
| Koga et al./2000 [21] | MFS | NSAIDs, neuropathic | NSAIDs, carbamazepine | Neither class was effective for pain relief in their cohort |
| Connelly et al./1990 [22] | Not specified | Epidural opioids | Fentanyl (epidural), then morphine | Epidural opioids are effective where IV opioids and other agents have failed |
| Genis et al./1989 [23] | Not specified | Epidural opioids | Epidural morphine (1–4 mg q8–24h) | 8/9 patients responded positively: they were pain-free during the day and slept at night |
| Johnson & Dunn/2008 [24] | Not specified | Opioids | Remifentanil infusion | Effective for 14 days with no significant tolerance |
| Ruts et al./2007 [25] | Radicular pain, GBS subtype not specified | Corticosteroids | Methylprednisolone + IVIg | Mixed results; radicular pain improved in most patients. A small sample size limits the ability to draw a definitive conclusion |
| van Doorn et al./2013 [26] | Not specified | Corticosteroids | High-dose steroids | EAN-PNS weakly recommends against high-dose corticosteroids |
| Hodgeman et al./2021 [28] | Not specified | IVIg + plasmapheresis | 142 g IVIg over 4 days | Gradual pain reduction; successful outcome |
| Ding et al./2018 [29] | Suspected GBS subtypes | IVIg | IVIg 0.4 mg/kg/day × 5 days | Significant pain improvement and symptom resolution in both cases |
| Nixon/1978 [30] | Not specified | Miscellaneous | Quinine sulfate ± aminophylline | Nocturnal cramping pain relief lasting 8–12 h |
| Kiper et al./2025 [31] | Not specified | Non-pharmacotherapy: physical therapy | Strength, ROM, functional training, aerobic | Improved function, fatigue, strength, and well-being |
| Al-Zamil et al./2024 [32] | Post-COVID GBS + ATM | Non-pharmacotherapy | TENS | Pain improvement; enhanced mobility and nerve function |
| Sendhilkumar et al./2013 [33] | Not specified | Non-pharmacotherapy: yoga, meditation | Pranayama yoga, meditation + rehab | Trend toward pain improvement; not statistically significant |
| Titus et al./2024 [34] | Sensory GBS | Multimodal | Hydromorphone, lorazepam, gabapentin | Refractory pain required escalation; emphasized individualized approaches |
MFS: Miller-Fischer Syndrome; GBS: Guillain-Barré Syndrome; ATM: acute transverse myelitis; NSAIDs: non-steroidal anti-inflammatory drugs; IVIg: intravenous immunoglobulin; TID: three times a day; BID: twice a day; TENS: transcutaneous electrical nerve stimulation; EAN-PNS: European Academy of Neurology and the Peripheral Nerve Society.
