Randomized Controlled Trial
The Effect of Immersive Virtual Reality Application on Anxiety, Pain, and Parental Satisfaction in the Perioperative Process of Children: A Randomized Controlled Trial.
To determine the effects of virtual reality (VR) interventions on pre- and postoperative anxiety, pain, and parental satisfaction in children. ⋯ Virtual reality interventions offer an effective nonpharmacological strategy for perioperatively managing children's anxiety and increasing parental satisfaction.

Randomized Controlled Trial Comparative Study
Postoperative analgesic effectiveness of ultrasound-guided bilateral erector spinae plane block vs. rectus sheath block for midline abdominal surgery in a low- and middle-income country: a randomised controlled trial.
The use of erector spinae plane block and rectus sheath block for postoperative analgesia in midline abdominal procedures is becoming more common. However, the most effective and appropriate method remains unclear. We aimed to compare the postoperative analgesic effecacy of ultrasound-guided bilateral erector spinae plane blocks with rectus sheath blocks for midline abdominal surgery in a low- and middle-income country. ⋯ Erector spinae plane blocks are more effective than rectus sheath blocks for the management of postoperative pain following midline abdominal surgery. Integration of erector spinae plane blocks into multimodal opioid-sparing analgesic strategies after midline abdominal surgeries may promote enhanced patient recovery in low-and middle-income countries.

Tramadol effects on brain activity during cognitive and emotional empathy for pain: a randomized controlled study.
Pain is perceived not only by personal experience but also vicariously. Pain empathy is the ability to share and understand other's intentions and emotions in their painful conditions, which can be divided into cognitive and emotional empathy. It remains unclear how centrally acting analgesics would modulate brain activity related to pain empathy and which component of pain empathy would be altered by analgesics. ⋯ Supramarginal gyrus activation correlated negatively with the thermal pain threshold. In experiment 2, we found that tramadol decreased activation in angular gyrus in cognitive empathy for pain compared with placebo but did not change brain activity in emotional empathy for pain. PERSPECTIVE: Centrally acting analgesics such as tramadol may have not only analgesic effects on self-experienced pain but also on the complex neural processing of pain empathy.

Randomized Controlled TrialRopivacaine and magnesium sulfate in sciatic nerve block at the popliteal level: randomized double-blind study.
Following surgical procedures, over 80% of patients experience acute pain, with half of them expressing dissatisfaction with pain relief. The modern approach to surgical treatment and pain management increasingly relies on implementing multimodal analgesia, which includes the use of adjuvants in addition to long-acting local anesthetics (such as ropivacaine). This double-blind randomized study evaluated the analgesic effect of magnesium sulfate added to ropivacaine in the sciatic nerve block at the popliteal level for bunion correction surgery. ⋯ Our results suggest that magnesium added to the local anesthetic extends sensory block duration, reduces postoperative pain, improves the quality of analgesia, decreases the need for additional opioids. Further studies are needed to confirm these preliminary findings.

Randomized Controlled Trial
Studying the effect of expectations on high-frequency electrical stimulation-induced pain and pinprick hypersensitivity.
Negative expectations can increase pain, but can they promote the development of central sensitization? This study used an inert treatment and verbal suggestions to induce expectations of increased high-frequency electrical stimulation (HFS)-induced pain and assessed their effects on pain ratings during HFS and HFS-induced pinprick hypersensitivity. Fifty healthy volunteers were randomly allocated to either a control group (N = 25) or a nocebo group (N = 25). Participants in both groups received a patch containing water on the right forearm. ⋯ HFS increased pinprick sensitivity but no group differences were found. Because of the lack of differences in expected pain and pain intensity ratings for HFS between groups, no firm conclusions can be drawn regarding their effect on pinprick hypersensitivity. PERSPECTIVE: This study shows that sham treatment combined with verbal suggestions induces a nocebo effect but does not necessarily change expectations and experience of upcoming pain.
