Liposomal bupivacaine is claimed by the manufacturer to provide analgesia for up to 72 h postoperatively. ⋯ There is moderate level evidence that liposomal bupivacaine reduces rest pain scores by 0.9 out of 10 units, when compared with long-acting local anaesthetics at 24 hours after surgery, and by 0.7 up to 72 hours after surgery.

Many clinical trials report significant improvements in osteoarthritis-related pain and function after total knee arthroplasty (TKA). Opioids are commonly prescribed for pain management of knee osteoarthritis and also perioperative pain after surgery. The extent of persistent opioid use after TKA is unknown. Because up to 20% of individuals have poor outcomes after TKA and prior opioid use is a risk factor for future opioid use, treatment effects from TKA clinical trials would be better understood by assessing opioid use data from trial participants. The purpose of this review was to determine the proportion of participants in TKA trials with opioid use before surgery and persistent use after surgery and how well clinical trials capture and report these variables. ⋯ Based on available research, it is not possible to determine if TKA is effective in reducing reliance on opioids for pain management. It also highlights the need to better track and report prior and long-term opioid use as a core outcome in future TKA trials.

Meta AnalysisComplications of Factor V Leiden in Adults Undergoing Noncardiac Surgical Procedures: A Systematic Review.
Factor V Leiden is the commonest hereditary prothrombotic allele, affecting 1% to 5% of the world's population. The objective of this study was to characterize the perioperative and postoperative outcomes of patients with Factor V Leiden compared to patients without a diagnosis of hereditary thrombophilia. This was a focused systematic review of studies including adult (>18 years) patients with Factor V Leiden (heterozygous or homozygous) undergoing noncardiac surgery. ⋯ Variable outcome definitions and durations of patient follow-up across different surgical procedures resulted in high study heterogeneity precluding the effective use of meta-analysis. Factor V Leiden status may confer additional risk for surgery-related adverse outcomes. Large, adequately powered studies are required to accurately estimate the degree of this risk by zygosity.

ReviewRecommendations and considerations for speeding the collapse of the non-ventilated lung during single-lung ventilation in thoracoscopic surgery: a literature review.
Video-assisted thoracoscopic thoracic surgery has the advantages of less physical damage, less postoperative pain, and a rapid recovery. Therefore, it is widely used in the clinic. The quality of nonventilated lung collapse is the key point of thoracoscopic surgery. ⋯ Therefore, it is important to achieve good lung collapse as soon as possible after opening the pleura. Over the past two decades, there have been reports of advances in research on the physiological mechanism of lung collapse and several kinds of techniques for speeding up lung collapse. This review will inform the advances of each technique, make recommendations for reasonable implementation and discuss their controversies and considerations.
