Chronic Pregabalin Treatment and Oxycodone Requirement after Spinal Surgery Versus Short Course Perioperative Administration: A Prospective, Nonrandomized Study.

Background: Although being controversial, pregabalin (PGB) is proposed during a short perioperative period  to improve pain relief.Comparisons between chronic and short-term users during lumbar spine surgery are lacking.

Objectives: The purpose was to compare opioid requirements and postoperative pain among PGB chronic users and naive patients receiving a 48-hour perioperative administration.

Impact of cleaning and disinfection procedures on microbial ecology and Salmonella antimicrobial resistance in a pig slaughterhouse.

To guarantee food safety, a better deciphering of ecology and adaptation strategies of bacterial pathogens such as Salmonella in food environments is crucial. The role of food processing conditions such as cleaning and disinfection procedures on antimicrobial resistance emergence should especially be investigated. In this work, the prevalence and antimicrobial resistance of Salmonella and the microbial ecology of associated surfaces communities were investigated in a pig slaughterhouse before and after cleaning and disinfection procedures.

A survey of the administration of prednisolone versus ibuprofen analgesic protocols after ambulatory tonsillectomy.

Introduction: Postoperative pain, nausea and vomiting are frequent symptoms after tonsillectomy. There have been controversies concerning the advantages and drawbacks of different analgesics in this setting, especially non-steroidal anti-inflammatory drugs, because of potential side effects. We have evaluated the effectiveness and safety of a shift from prednisolone to ibuprofen for postoperative analgesia after tonsillectomy.

Pain and recovery after total knee arthroplasty: a 12-month follow-up after a prospective randomized study evaluating Nefopam and Ketamine for early rehabilitation.

Objectives: Ketamine and nefopam has been documented to decrease pain intensity and improve rehabilitation after total knee arthroplasty (TKA). We conducted a follow-up study of a previously randomized clinical trial to determine the prevalence and risk factors of chronic pain 1 year after TKA and to assess the role of perioperative administration of ketamine and nefopam.

Materials And Methods: The original randomized, double-blind trial evaluated postoperative pain in 75 patients scheduled for TKA who received either a 48-hour infusion of ketamine or nefopam compared with placebo.

Perineural ultrasound-guided catheter bacterial colonization: a prospective evaluation in 747 cases.

Background And Objectives: Ultrasound guidance is increasingly used for catheter insertion and could make it more complicated to guarantee aseptic insertion of catheters. The current study evaluated the incidence of colonization of ultrasound-guided perineural catheter (US-PNC) placed for postoperative analgesia.

Methods: We evaluated prospectively for 14 months 760 ultrasound-guided catheters in a single center placed under sterile conditions.

Postoperative efficacies of femoral nerve catheters sited using ultrasound combined with neurostimulation compared with neurostimulation alone for total knee arthroplasty.

Background And Objective: Neurostimulation is commonly used to perform femoral nerve block. Ultrasound can be used to identify nerve structures and guide needle placement. The aim of this study was to compare postoperative analgesic efficiency when femoral nerve catheters were sited using ultrasound (in-plane approach) combined with neurostimulation or neurostimulation alone, for total knee arthroplasty.
