ObjectivePerioperative gabapentine administration improves analgesia, reduces postoperative nausea and vomiting, but increases sedation. Pregabalin is also a gabapentinoid, with an improved bioavailability. This systematic review evaluates the analgesic effect and tolerance of perioperative pregabaline.Study DesignSystematic review.MethodsSystematic search in Pubmed database of clinical human randomized controlled studies dealing with perioperative administration of pregabalin. A quantitative review of pregabalin efficiency and an analysis of the main side effects reported in these studies was then performed.ResultsTwenty-three study arms (884 patients) received at least one dose of pregabalin in 17 studies (totalizing 1577 patients). Pregabalin improved analgesia in 11 of 23 study arms. Pregabalin improved analgesia in three of 12 study arms after ambulatory surgery, and in eight of 11 after major surgery (P=0.04). Two of three studies about chronic postoperative pain revealed improved results in pregabalin groups. Nevertheless, pregabalin did not reduce postoperative nausea/vomiting, pruritus and headache, but increased trouble with vision, drowsiness, severe sedation and dizziness during the first postoperative hours, without severe clinical consequence. Severe sedation seemed clearly dose dependant, while drowsiness, dizziness or visual disturbance did not.ConclusionA favorable benefit risk-ratio is demonstrated only for major surgery (excluding ambulatory surgery). The lack of data concerning tolerance of pregabalin in the elderly and/or in case of renal dysfunction forbids any conclusion in these populations.Copyright © 2011 Elsevier Masson SAS.
