Pain syndromes of Guillain-Barre are neuropathic as well as nociceptive in origin. We aimed to evaluate the therapeutic efficacy of gabapentin in relieving the bimodal nature of pain in Guillain-Barre syndrome in a randomized, double-blinded, placebo-controlled, crossover study in 18 patients admitted to the intensive care unit for ventilatory support. Patients were assigned to receive either gabapentin (15 mg.kg(-1).d(-1) in 3 divided doses) or matching placebo as initial medication for 7 days. After a 2-day washout period, those who previously received gabapentin received placebo, and those previously receiving placebo received gabapentin as in the initial phase. Fentanyl 2 mug/kg was used as a rescue analgesic on patient demand or when the pain score was >5 on a numeric rating scale of 0-10. The numeric rating score, sedation score, consumption of fentanyl, and adverse effects were noted, and these observed variables were compared. The numeric pain score decreased from 7.22 +/- 0.83 to 2.33 +/- 1.67 on the second day after initiation of gabapentin therapy and remained low during the period of gabapentin therapy (2.06 +/- 0.63) (P < 0.001). There was a significant decrease in the need for fentanyl from Day 1 to Day 7 during the gabapentin therapy period (211.11 +/- 21.39 to 65.53 +/- 16.17 [mu g]) in comparison to the placebo therapy period (319.44 +/- 25.08 to 316.67 +/- 24.25 [mu g]) (P < 0.001).
