Effect of dexmedetomidine on CD4+ T cells and programmed cell death protein-1 in postoperative analgesia: a prospective, randomized, controlled study.
Surgical trauma inhibits cellular immunity. Dexmedetomidine produces opioid-sparing effect and an impact on immune response. ⋯ Dexmedetomidine increases the differentiation of Th1 and Treg cells and reduces the expression of PD-1 on CD4+ T cells. Dexmedetomidine may assist to ameliorate postoperative pain and attenuate pro-inflammatory response. There might be a negative correlation between pain and Th1 cells.

Children with symptoms of hypotonia (reduction of postural tone of lower limbs and trunk with or without changes in phasic tone) are frequently anaesthetized for diagnostic and therapeutic interventions. This review outlines the underlying causes and classifications, and the anaesthesiologic pre- and peri-operative management of hypotonic children. Hypotonia may have a large range of aetiologies that be categorized into central and/or peripheral hypotonia. ⋯ Adequate postoperative pain treatment is essential to limit stress and metabolic alteration. Preferably a locoregional technique is used to reduce the increased risk of respiratory depression. A multidisciplinary preoperative approach taking into account the differential diagnosis of the underlying disease of the floppy child is recommended.

While knee and hip replacements are intended to relieve pain and improve function, up to 44% of knee replacement patients and 27% of hip replacement patients report persistent postoperative joint pain. Improving surgical pain management is essential. We conducted a single-site, three-arm, parallel-group randomized clinical trial conducted at an orthopedic clinic, among patients undergoing total joint arthroplasty (TJA) of the hip or knee. ⋯ Moderation analysis revealed surgery type did not differentially impact the three interventions. Thus, a single session of a simple, scripted MM intervention may be able to immediately decrease TJA patients' preoperative clinical symptomology and improve postoperative physical function. As such, embedding brief MM interventions in surgical care pathways has the potential to improve surgical outcomes for the millions of patients receiving TJA each year.

Placebo effects have traditionally involved concealment or deception. However, recent evidence suggests that placebo effects can also be elicited when prescribed transparently as "open-label placebos" (OLP), and that the pairing of an unconditioned stimulus (e.g., opioid analgesic) with a conditioned stimulus (e.g., placebo pill) can lead to the conditioned stimulus alone reducing pain. In this randomized control trial, we investigated whether combining conditioning with an open-label placebo (COLP) in the immediate postoperative period could reduce daily opioid use and postsurgical pain among patients recovering from spine surgery. ⋯ Patients in the COLP group consumed approximately 30% less daily morphine mg equivalents (MMEs) compared to patients in the TAU group during POD 1-17 (-14.5 daily MME; 95% CI: [-26.8, -2.2]). Daily worst pain scores were also lower in the COLP group (-1.0 point on the 10-point scale; 95% CI: [-2.0, -0.1]), although a significant difference was not detected in average daily pain between the groups (-0.8 point; 95% CI: [-1.7, 0.2]). These findings suggest that COLP may serve as a potential adjuvant analgesic therapy to decrease opioid consumption in the early postoperative period, without increasing pain.

Behavioral pain scales are recommended to assess postoperative pain for children who are too young to use self-report tools. Their main limitation is underestimation of pain in the days following an intervention. Although relevant, facial expression is not used in daily clinical practice. This prospective study aimed to assess the validity and reliability of the Facial Action Summary Score (FASS), a five-item scale, to assess postoperative pain until hospital discharge in children <7 years. ⋯ This work highlights the interest in using facial expression in daily clinical practice to manage postoperative pain. The FASS is easy to use with excellent psychometric properties and is particularly sensitive to measure pain in the days following surgery.
