To investigate paediatric nurses' postoperative pain management practices with the aim of identifying the factors associated with undermanaged paediatric postoperative pain. ⋯ The results of this review indicate nurses' assessment and management of children's pain is not consistent with published guidelines. Results of studies exploring nurse and child related factors are inconclusive. Research needs to examine the impact of organisational factors on nurses' pain care practices. Intervention studies are needed to determine the most effective strategies to support and improve nurses' pain care for children.

Hyperalgesia is one of the negative consequences following intraoperative analgesia with remifentanil. Peroxynitrite is a critical determinant in nociceptive process. Peroxynitrite inactivates iron-sulfur cluster that results in mitochondrial dysfunction and the release of iron, leading to mitochondrial iron accumulation. Iron accumulation mediated by divalent metal transporter 1 (DMT1) plays a key role in N-methyl-D-aspartate neurotoxicity. This study aims to determine whether peroxynitrite contributes to remifentanil-induced postoperative hyperalgesia via DMT1-mediated iron accumulation. ⋯ Our study identifies that spinal peroxynitrite activates DMT1(-)IRE, leading to abnormal iron accumulation in remifentanil-induced postoperative hyperalgesia, while providing the rationale for the development of molecular hydrogen and "iron-targeted" therapies.

Clinical TrialPre-operative baroreflex sensitivity and efferent cardiac parasympathetic activity are correlated with post-operative pain.
A maladaptation of the autonomic nervous system may been seen in patients with chronic pain that includes persistent changes in the autonomic tone, increased heart rate, and reduced heart rate variability and baroreflex sensitivity. Baroreflex sensitivity and acute pain intensity have been reported to be inversely correlated. However, it is unknown whether the same correlation applies with regard to post-operative pain. In the present study, autonomic function was measured in patients scheduled for minor hand surgery and correlated with early and persistent pain after the procedure. Thus, the cause (autonomic imbalance) was present before the effect (post-operative pain). Our primary hypothesis was that a lower level of pre-operative baroreflex sensitivity is correlated with increased early post-operative pain. ⋯ The findings suggest that a low pre-operative level of baroreflex sensitivity is associated with higher post-operative pain intensity. To our knowledge, this is the first study to show the correlation between baroreflex sensitivity and post-operative pain.

Comparative Study
Neuraxial anesthesia improves long-term survival after total joint replacement: a retrospective nationwide population-based study in Taiwan.
This study explored the effects of general (GA) and neuraxial (NA) anesthesia on the outcomes of primary total joint replacement (TJR) in terms of postoperative mortality, length of stay (LOS), and hospital treatment costs. ⋯ Our results support the use of NA for primary TJR. The improvements in hospital costs persist even when anesthesia costs are removed. The mechanism underlying the association between NA and long-term survival is unknown.
