Perioperative oral pregabalin reduces chronic pain after total knee arthroplasty: a prospective, randomized, controlled trial.

Kenneth J Tuman, Mario Moric, Craig J Della Valle … (2010)

Despite the enormous success of total knee arthroplasty (TKA), chronic neuropathic pain can develop postoperatively and is both distressing and difficult to treat once established. We hypothesized that perioperative treatment with pregabalin, a chronic pain medication, would reduce the incidence of postsurgical neuropathic pain. We performed a randomized, placebo-controlled, double-blind trial of pregabalin (300 mg) administered before TKA and for 14 days after TKA (150-50 mg twice daily). Patients were screened for the presence of neuropathic pain at 3 and 6 mo postoperatively using the Leeds Assessment of Neuropathic Symptoms and Signs scale. Secondary outcomes included postsurgical recovery and rehabilitation measures, including knee range of motion, opioid consumption, postoperative pain scores, sleep disturbance, and time to discharge as well as the occurrence of postoperative systemic complications. Of the 240 patients randomly assigned to the 2 treatment groups (120 in each), data for the primary outcome were obtained from 113 pregabalin patients and 115 placebo patients. At both 3 and 6 mo postoperatively, the incidence of neuropathic pain was less frequent in the pregabalin group (0%) compared with the placebo group (8.7% and 5.2% at 3 and 6 mo, respectively; P = 0.001 and P = 0.014). Patients receiving pregabalin also consumed less epidural opioids (P = 0.003), required less oral opioid pain medication while hospitalized (P = 0.005), and had greater active flexion over the first 30 postoperative days (P = 0.013). There were no differences in the actual recorded duration of hospitalization between the 2 groups, although time to achieve hospital discharge criteria was longer for placebo patients, 69.0 +/- 16.0 h (mean +/- SD), than that of pregabalin patients, 60.2 +/- 15.8 h (P = 0.001). Sedation (P = 0.005) and confusion (P = 0.013) were more frequent on the day of surgery and postoperative day 1 in patients receiving pregabalin. Perioperative pregabalin administration reduces the incidence of chronic neuropathic pain after TKA, with less opioid consumption and better range of motion during the first 30 days of rehabilitation. However, in the doses tested, it is associated with a higher risk of early postoperative sedation and confusion.

Efficacy of pregabalin in acute postoperative pain: a meta-analysis.

J ZHANG, K.-Y. Ho, Y. WANG (2011)

Multimodal treatment of postoperative pain using adjuncts such as gabapentin is becoming more common. Pregabalin has anti-hyperalgesic properties similar to gabapentin. In this systematic review, we evaluated randomized, controlled trials (RCTs) for the analgesic efficacy and opioid-sparing effect of pregabalin in acute postoperative pain. A systematic search of Medline (1966-2010), the Cochrane Central Register of Controlled Trials (CENTRAL), and Google Scholar was performed. We identified 11 valid RCTs that used pregabalin for acute postoperative pain. Postoperative pain intensity was not reduced by pregabalin. Cumulative opioid consumption at 24 h was significantly decreased with pregabalin. At pregabalin doses of <300 mg, there was a reduction of 8.8 mg [weighted mean difference (WMD)]. At pregabalin doses ≥300 mg, cumulative opioid consumption was even lower (WMD, -13.4 mg). Pregabalin reduced opioid-related adverse effects such as vomiting [risk ratio (RR) 0.73; 95% confidence interval (CI) 0.56-0.95]. However, the risk of visual disturbance was greater (RR 3.29; 95% CI 1.95-5.57). Perioperative pregabalin administration reduced opioid consumption and opioid-related adverse effects after surgery.

Systematic review of movement-evoked pain versus pain at rest in postsurgical clinical trials and meta-analyses: a fundamental distinction requiring standardized measurement.

Sanjho Srikandarajah, Ian Gilron (2011)

To estimate frequency of movement-evoked pain (MEP) measurement in human postsurgical investigations, we reviewed thoracotomy, knee arthroplasty, and hysterectomy clinical trials and meta-analyses. Only 39% of trials measured MEP and 52% failed to identify pain outcome as pain at rest (PAR) or MEP. Temporal trending did not suggest that MEP measurement is becoming more frequent. Trials measuring both MEP and PAR suggest that MEP is 95-226% more intense than PAR in the first 3 postoperative days. Among trials measuring MEP, 38% did not specify the physical maneuver used to assess MEP. Five of 7 meta-analyses reviewed (71%) did not distinguish between PAR and MEP, and none of the 7 meta-analyses declared the 20-59% of reviewed trials that had failed to identify their pain outcome as PAR or MEP. These results suggest an unchanging neglect of MEP in postsurgical pain trials and frequent failure to identify pain outcome as PAR or MEP. This is an important problem because MEP is usually more severe than PAR; MEP exerts a more direct adverse impact on postsurgical functional recovery and several current and novel pain treatments differentially affect MEP vs PAR. Failure to distinguish between PAR and MEP and standardize their measurement threatens trial precision and ability to identify interventions with the most clinically relevant effects on pain. We therefore recommend developing consistent terminology regarding PAR and MEP, considering inclusion of MEP as a pain outcome in every postsurgical trial, and standardizing measurement of PAR and MEP on a procedure-specific basis.
