Continuous paravertebral block is commonly used for post-thoracotomy analgesia and compares favourably with other systemic and regional methods with regard to safety and efficacy. No major complications of continuous paravertebral block for post-thoracotomy analgesia have been reported previously. ⋯ Postoperative delirium was a diagnostic confounder. We discuss the potential causes and means of avoiding similar complications in the future.

Acute kidney injury during endovascular aortic repair can result in a reduction in the postoperative glomerular filtration rate (GFR). The 'pleiotropic' effects of statins offer a potential mechanism of reducing the postoperative decline in the GFR. We therefore tested the hypothesis that in patients undergoing endovascular aortic repair, the GFR decreases less in patients taking preoperative statins than in those who do not. ⋯ Statin therapy is not associated with a statistically significant change in the mean postoperative GFR in patients undergoing endovascular aortic surgery, nor a reduction in the risk of a GFR decline of >25%.

Although postoperative pain is traditionally considered to be nociceptive in origin, a proportion of patients experience a significant neuropathic component to their pain experience. Diagnosing neuropathic pain in this setting is challenging, and there are no published guidelines or screening tools designed for use in the immediate postoperative setting. We hypothesized that acute pain specialists were diagnosing a neuropathic component to acute pain, and this study aimed to obtain an expert agreed list of pain characteristics that could be used to aid diagnosis. ⋯ The Delphi survey suggests that neuropathic pain in the immediate postoperative period is diagnosed in a different way to chronic neuropathic pain, with items such as response to medications considered more useful than signs such as those representing autonomic changes.

Optimized anaesthetic management might improve the outcome after cancer surgery. A retrospective analysis was performed to assess the association between spinal anaesthesia (SpA) or general anaesthesia (GA) and survival in patients undergoing surgery for malignant melanoma (MM). ⋯ These data suggest an association between anaesthetic technique and cancer outcome in MM patients after lymph-node dissection. Prospective controlled trials on this topic are warranted.
