The aim of this study was to evaluate differences in pain scores with different visual analog scale (VAS) presentations and to compare those differences with a numeric rating scale. We also asked the patients for preference of the different methods. ⋯ For daily clinical practice for guiding postoperative analgesic treatment, the NRS seems to be a good option measuring pain reliably with good patient understanding and acceptance. For pain research, where there may be more time to explain the method and when a scale with more data points may be preferred, a VAS horizontal including stop lines at the ends can be recommended.

Randomized Controlled Trial
Effects of anesthetics on early postoperative cognitive outcome and intraoperative cerebral oxygen balance in patients undergoing lung surgery: a randomized clinical trial.
One-lung ventilation (OLV) may impair cerebral oxygen balance and induce postoperative cognitive dysfunction (POCD). It is unclear whether the type of anesthetic influences the incidence of POCD in patients undergoing OLV. This prospective study compared the incidence of POCD and intraoperative cerebral oxygen desaturation in OLV patients anesthetized with propofol vs sevoflurane during lung surgery. ⋯ UMIN 000002826).

This study aims to assess the impact of postoperative intravenous (IV) acetaminophen on opioid requirements and pain scores in patients following gynecologic procedures. ⋯ Postoperative administration of IV acetaminophen did not provide a significant opioid-sparing effect in patients undergoing gynecologic procedures.

Previous evidence suggests that opioid-tolerant patients are less responsive to local anesthetics (LAs) for postoperative pain management. ⋯ These preclinical data suggest that the morphine-induced decrease in LA potency is due, at least in part, to the intrinsic changes in the peripheral nerve. Identification of the underlying mechanisms may suggest strategies for more effective postoperative pain management in the growing population of opioid-tolerant patients.
