Meta AnalysisRegional anesthesia techniques and postoperative delirium: systematic review and meta-analysis.
Postoperative delirium is a frequent occurrence in the elderly surgical population. As a comprehensive list of predictive factors remains unknown, an opioid-sparing approach incorporating regional anesthesia techniques has been suggested to decrease its incidence. Due to the lack of conclusive evidence on the topic, we conducted a systematic review and meta-analysis to investigate the potential impact of regional anesthesia and analgesia on postoperative delirium. ⋯ These results show that postoperative delirium may be decreased when regional techniques are used in the postoperative period as an analgesic strategy. Intraoperative regional anesthesia alone may not decrease postoperative delirium since there are other factors that may influence this outcome.

ReviewPharmacokinetic modelling and simulation to understand diamorphine dose-response in neonates, children and adolescents.
Pharmacokinetic-pharmacodynamic modeling and simulation can facilitate understanding and prediction of exposure-response relationships in children with acute or chronic pain. The pharmacokinetics of diamorphine (diacetylmorphine, heroin), a strong opioid, remain poorly quantified in children and dose is often guided by clinical acumen. This tutorial demonstrates how a model to describe intranasal and intravenous diamorphine pharmacokinetics can be fashioned from a model for diamorphine disposition in adults and a model describing morphine disposition in children. ⋯ These indicated that morphine exposure in children after intranasal diamorphine 0.1 mg.kg-1 was similar to that after intranasal diamorphine 5 mg in adults. A target concentration of morphine 30 μg. L-1 can be achieved by a diamorphine intravenous infusion in neonates 14 μg.kg-1 .h-1 , in a 5-year-old child 42 μg.kg-1 .h-1 and in an 15 year-old-adolescent 33 μg.kg-1 .h-1 .

Randomized Controlled TrialEffect of opioid-free anesthesia on postoperative analgesia after laparoscopic gynecologic surgery.
We performed this randomized controlled trial to evaluate the effect of opioid-free anesthesia (OFA) on postoperative analgesia after laparoscopic gynecologic surgery. ⋯ Compared to opioid-inclusive anesthesia during laparoscopic gynecologic surgery, OFA was associated with significant improvement in postoperative analgesia, reduced PONV incidence prevalence and severity, and faster first passage of flatus.

In-Hospital Opioid Consumption After the Previous Cesarean Delivery Weakly Predicts Opioid Consumption After Index Delivery: A Retrospective Cohort Study.
To predict opioid consumption and pain intensity after the index cesarean delivery, we tested a hypothesis that opioid consumption after the previous cesarean delivery of the same patient can predict the opioid consumption after the index cesarean delivery. We further tested a secondary hypothesis that the pain scores after the previous cesarean delivery can predict the pain scores after the index cesarean delivery. ⋯ Opioid consumption and pain scores after women's previous cesarean delivery only explain 27% of variance of opioid consumption and 18% of variance of their pain after their index cesarean delivery. Therefore, previous cesarean delivery analgesic metrics are not robust enough to be used as clinically applicable predictors for index delivery.

Virtual Reality Based Guided Meditation for Patients with Opioid Tolerance and Opioid Use Disorders.
The management of acute pain in patients with pre-existing opioid tolerance or opioid use disorders presents unique challenges. In light of the concerns regarding opioid use, safe and effective alternatives to opioid medications are of increasing interest. ⋯ This study demonstrates that the use of guided meditation through virtual reality can result in statistically significant reductions in patient-reported pain scores.
