A state-of-the-art pain protocol for total knee replacement David F. Dalury, MD University of Maryland St Joseph Orthopedics, Towson Orthopaedic Associates, Towson, MD, USA article info Article history: Received 21 December 2015 Received in revised form 15 January 2016 Accepted 16 January 2016 Available online xxx Keywords: Total knee Pregabalin is accepted to be more potent, and with fewer adverse effects, than its class counterpart gabapentin. It has fast gastrointestinal absorption, a high bioavailability, and its serum representation is dose-proportional leading to a predictable and near-linear pharmacokinetic profile. 6 The maximum plasma concentration is reached at 1 h after oral administration, and its elimination The literature search was conducted by following databases: Medline, Cochrane database, ClinicalTrials.gov, PubMed, and Embase. The following keywords including pain management, postoperative pain, total knee arthroplasties, total knee replacement, and gabapentin were used for searching. 1. Inclusion criteria. Studies were considered eligible We would like to show you a description here but the site won’t allow us. Gabapentin resulted in less total patient-controlled analgesia (PCA) morphine use over 48 hours postoperatively (P <0.05), better active knee flexion on postoperative days (PODs) 2 and 3 (P <0.05 for both), and less pruritus (P <0.05) than placebo.¹⁰. While gabapentin may have some benefit in the short-term and some older adults may have persistent pain that warrants prolonged use of gabapentin, particularly after spinal surgery, we speculate that a large proportion of this prolonged use is not intentional, and that the system needs to be improved to prevent both polypharmacy and A total of 1805 patients aged 18 to 75 years scheduled for surgery (thoracotomy, video-assisted thoracoscopic surgery, total hip replacement, total knee replacement, mastectomy, breast lumpectomy, hand surgery, carpal tunnel surgery, knee arthroscopy, shoulder arthroplasty, and shoulder arthroscopy) were screened. Pain management after total hip arthroplasty (THA) varies and has been widely studied in recent years. Gabapentin as a third-generation antiepileptic drug that selectively affects the nociceptive process has been used for pain relief after THA. This Pregabalin after discharge reduces postoperative pain, neuropathic pain, and opioid consumption after primary TJA, but gabapentin does not reduce pain or opioid consumption. Strength of Recommendation: Strong. Rationale: Six high quality studies evaluated the efficacy of post-discharge gabapentinoids on pain The results showed a statistically significant decrease in morphine use in the first 24 hours after surgery in the celecoxib/gabapentin group compared with the placebo group: G = 38.3 (29.5 mg), P = 48.2 (29.4 mg (p .0125). There was no statistically significant difference in pain or sedation between the groups (Clarke et al., 2014). A variety of modalities have been applied to reduce postoperative pain after TKA, including intravenous patient-controlled epidural analgesia with opioids, local infiltration analgesia with levobupivacaine, ketorolac and adrenaline, and gabapentin. 5,6 The use of opioids is limited by adverse effects such as nausea, vomiting, and pruritus. 7 Gabapentin (Neurontin) or pregabalin (Lyrica): These are medications that specifically treat certain seizures and nerve pain. However, doctors may prescribe Trusted Source. pain after the Clarke HA, Katz J, McCartney CJ, et al. Perioperative gabapentin reduces 24 h opioid consumption and improves in-hospital rehabilitation but not post-discharge outcomes after total knee arthroplasty with peripheral nerve block. Postoperative pain after total knee arthroplasty (TKA) and total hip arthroplasty (THA) influence patients’ rehabilitation and life quality. Although gabapentin has been widely used for analgesia, its efficacy is still controversial in TKA and THA. day trial, patients in the gabapentin group showed improved VAS pain scores and improved Leeds Assessment of Neuropathic Symptoms and Signs (LANSS) scores compared to patients in the naproxen group. In 2006, Sihoe et al. evaluated gabapentin in the treatment of chronic pain after chest surgery (6). This was a heterogeneous group of patients. Their findings, recently published in the journal Anesthesiology, indicate that the analgesic benefits of pregabalin and gabapentin after surgery are negligible, regardless of the dose or type of operation. Gabapentinoids were also ineffective in preventing chronic pain from developing after surgery, one of the primary justifications for using
