Randomized Controlled TrialRelationship Between Endogenous Opioid Function and Opioid Analgesic Adverse Effects.
Our recent work indicates that endogenous opioid activity influences analgesic responses to opioid medications. This secondary analysis evaluated whether endogenous opioid activity is associated with degree of opioid analgesic adverse effects, and whether chronic pain status and sex affect these adverse effects. ⋯ No consistent relationships were observed between endogenous opioid function and morphine-related adverse effects. This is in stark contrast to our previous observation of strong relationships between elevated endogenous opioid function and smaller morphine analgesic effects.

Randomized Controlled TrialA Prospective Randomized Observer-Blinded Study to Assess Postoperative Analgesia Provided by an Ultrasound-Guided Bilateral Thoracic Paravertebral Block for Children Undergoing the Nuss Procedure.
This prospective, randomized, single-blinded study evaluates the effectiveness of the ultrasound-guided bilateral thoracic paravertebral (BTPV) block for providing postoperative pain control in children undergoing the Nuss procedure. ⋯ Ultrasound-guided BTPV block provides improved postoperative analgesia for children undergoing the Nuss procedure as compared with intravenous PCA and decreases the incidence of postoperative behavioral disturbance.
