Virtual reality is a promising method to manage pain. Distraction-based virtual reality (VR-D) is thought to reduce pain by redirecting attention. Although VR-D can reduce pain associated with acutely painful procedures, it is unclear whether VR-D can reduce pain after surgery. We assessed the ability of a single VR-D session to decrease postoperative pain and anxiety and explored whether pain catastrophizing and anxiety sensitivity influenced these outcomes in children after surgery. ⋯ VR-D may be beneficial in transiently reducing pain intensity, unpleasantness, and anxiety in children with postoperative pain. This study informs the design of a larger, randomized, controlled study assessing VR-D for acute postoperative pain and anxiety management.

Pain severity and opioid requirements in the postoperative period show substantial and clinically significant inter-patient variation due mainly to factors such as age, surgery type, and duration. Genetic factors have not been adequately assessed except for the neuronal OPRM1 rs1799971 and COMT rs4680, whereas the contribution of innate immune signaling pathway genetics has seldom been investigated. ⋯ This is the highest known value reported for genetic contributions (38%) to morphine use in the acute postoperative pain setting. Our findings highlight the need to incorporate both genetic and nongenetic factors and consider ethnicity-dependent and nonadditive genotypic models in the assessment of factors that contribute to variability in opioid use.

This study was a retrospective review of patients treated in a single institution. We performed a cluster analysis of the degree of preoperative stenosis to investigate the effect of indirect neural decompression in single-level lateral lumbar interbody fusion (LLIF). Surgery is generally indicated for patients with severe stenosis. ⋯ Mean midsagittal CD and axial CCA on MRI magnetic resonance imaging increased significantly in all groups, but as with DA and DH, the changes in axial CCA and midsagittal CD did not differ between groups. The numeric rating scale score did not differ between groups at any time. The cluster analysis results suggested that postoperative changes in indirect neural decompression for severe stenosis after LLIF similar for moderate and mild stenosis and that pain did not differ according to the severity of stenosis after surgery.

Randomized Controlled Trial
Adding a low-concentration sciatic nerve block to total knee arthroplasty in patients susceptible to the adverse effects of non-steroidal anti-inflammatory drugs (NSAIDs): a randomized controlled trial.
This study compared the effects of adductor canal blocks with those of a low concentration of popliteal-sciatic nerve block (SNB) and dexamethasone as an adjunctive technique for total knee arthroplasties (TKA) in patients susceptible to the adverse effects of NSAIDs. ⋯ For patients susceptible to the adverse effects of NSAIDs, a low concentration of SNB and dexamethasone is an effective adjunctive technique for early postoperative pain control (especially on movement) following TKAs, without an increase in motor weakness.

The association of psychological factors with postoperative pain has been well documented. The incorporation of psychoeducational intervention into a standard analgesia protocol seems to be an attractive approach for the management of acute postoperative pain. Our study aimed to evaluate the impact of psychoeducational intervention on acute postoperative pain in pulmonary nodule (PN) patients treated with thoracoscopic surgery. ⋯ Psychoeducational intervention for PN patients treated with thoracoscopic surgery resulted in reduced acute postoperative pain, less opioid consumption and fewer opioid-related side effects.
