A systematic review and meta‐analysis of ketamine for the prevention of persistent post‐surgical pain

Abstract

While post‐operative pain routinely resolves, persistent post‐surgical pain ( PPSP ) is common in certain surgeries; it causes disability, lowers quality of life and has economic consequences. The objectives of this systematic review and meta‐analysis were to evaluate the effectiveness of ketamine in reducing the prevalence and severity of PPSP and to assess safety associated with its use. We searched the C ochrane C entral R egister of C ontrolled T rials, MEDLINE and EMBASE through D ecember 2012 for articles in any language. We included randomized, controlled trials in adults in which ketamine was administered perioperatively via any route. Seventeen studies, the majority of which administered ketamine intravenously, met all inclusion criteria. The overall risk of developing PPSP was not significantly reduced at any time point in the ketamine group vs. placebo, nor did comparisons of pain severity scores reach statistical significance. Sensitivity analysis of exclusively intravenous ketamine studies included in this meta‐analysis demonstrated statistically significant reductions in risk of developing PPSP at 3 and 6 months ( P = 0.01 and P = 0.04, respectively). Adverse event rates were similar between ketamine and placebo groups. The study data from our review are heterogeneous and demonstrate efficacy of intravenously administered ketamine only in comparison with placebo. Highly variable timing and dosing of ketamine in these studies suggest that no unifying effective regimen has emerged. Future research should focus on clinically relevant outcomes, should stratify patients with pre‐existing pain and possible central sensitization and should enroll sufficiently large numbers to account for loss to follow‐up in long‐term studies.

  • McNicol et al.'s meta-analysis of combined routes of ketamine use did not show any significant difference from placebo.

  • McNicol et al. did not find any statistically significant difference in the incidence of side effects (hallucinations, nightmares, excessive sedation, nausea and vomiting) except for visual disturbances (nystagmus and diplopia) with ketamine.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
