Optimizing the Yield of Abnormal Preoperative Chest Radiographs in Elective Non-cardiothoracic Surgery: Development of a Risk Prediction Score and External Validation.

Background: Guideline recommendations for preoperative chest radiographs vary to the extent that individual patient benefit is unclear. We developed and validated a prediction score for abnormal preoperative chest radiographs in adult patients undergoing elective non-cardiothoracic surgery.

Methods: Our prospective observational study recruited 703 adult patients who underwent elective non-cardiothoracic surgery at Ramathibodi Hospital.

Lumbar Epidural Corticosteroid Injection Reduces Subacute Pain and Improves Knee Function in the First Six Weeks After Total Knee Arthroplasty: A Double-Blinded Randomized Trial.

Background: Pain control immediately following total knee arthroplasty (TKA) has been a focus for orthopaedists. However, control of subacute pain, which may persist up to 3 months, is usually not optimized. The efficacy of epidural corticosteroids in reducing pain after surgery is documented, but data on their efficacy in controlling subacute pain after TKA are lacking.

The efficacy of local infiltration analgesia in the early postoperative period after total knee arthroplasty: A systematic review and meta-analysis.

Background: Local infiltration analgesia (LIA) has emerged as an alternative treatment for postoperative pain after total knee arthroplasty (TKA). Its efficacy remains inconclusive with inconsistent results from previous studies and meta-analyses. There is no agreement on which local anaesthetic agent and infiltration technique is most effective and well tolerated.
