ReviewManagement of sedation during weaning from mechanical ventilation.
Critically ill patients frequently require mechanical ventilation and often receive sedation to control pain, reduce anxiety, and facilitate patient-ventilator interactions. Weaning from mechanical ventilation is intertwined with sedation management. In this review, we analyze the current evidence for sedation management during ventilatory weaning, including level of sedation, timing of sedation weaning, analgesic and sedative choices, and sedation management in acute respiratory distress syndrome (ARDS). ⋯ Light or no sedation strategies that prioritize analgesia prior to sedatives along with paired SATs/SBTs promote ventilator liberation. Dexmedetomidine may have a role in weaning for agitated patients. Further investigation is needed into optimal sedation management for patients with ARDS.

As the incidence and survival rates of patients with cancer continues to grow, an increasing number of people are living with comorbidities, which often manifests as cancer-induced bone pain (CIBP). The majority of patients with CIBP report poor pain control from currently available analgesics. A conotoxin, Contulakin-G (CGX), has been demonstrated to be an antinociceptive agent in postsurgical and neuropathic pain states via a neurotensin receptor 2 (NTSR2)-mediated pathway. ⋯ Moreover, at antinociceptive doses, CGX had no impact on motor behavior in rodents with CIBP. Finally, RNAScope and immunoblotting analysis revealed expression of NTSR2 in both dorsal and ventral horns, while Cav2.3 was minimally expressed in the ventral horn, possibly explaining the sensory selectivity of CGX. Together, these findings support advancing CGX as a potential therapeutic for cancer pain.

Randomized Controlled Trial
Efficacy of Perineural Dexmedetomidine in Ultrasound-guided Interscalene Block on Rebound Pain after Shoulder Arthroscopy.
This prospective, randomized, double-blind trial was performed to investigate the effect on rebound pain incidence of mixing dexmedetomidine (DEX) with local anesthetics in a combined injection interscalene block (ISB) during shoulder arthroscopy. ⋯ Perineural DEX added to ISB exerts a beneficial effect on the incidence of rebound pain after ISB in patients undergoing shoulder arthroscopy. Perineural DEX facilitated the implementation of multimodal analgesia in the early stage after operation.

Randomized Controlled Trial Multicenter Study
Reduction of postoperative pain and opioid consumption by VVZ-149, first-in-class analgesic molecule: A confirmatory phase 3 trial of laparoscopic colectomy.
VVZ-149 is a small molecule that inhibits the glycine transporter type 2 and the serotonin receptor 5-hydroxytryptamine 2 A. In this Phase 3 study, we investigated the efficacy and safety of VVZ-149 as a single-use injectable analgesic for treating moderate to severe postoperative pain after laparoscopic colectomy. ⋯ Trial Number NCT05764525.

Neurocognitive symptoms (NCSs) may be early indicators of opioid-related harm. We aimed to evaluate the incidence and potential attribution of opioid-related NCS among patients on long-term opioid therapy (LOT) by using natural language processing to extract data from the electronic health records within the Veterans Health Administration. ⋯ This study suggests that opioid-related NCS are most likely to occur during LOT, indicating a potential temporal association with opioid use. These findings highlight the importance of monitoring NCS in patients on LOT as part of a broader strategy to mitigate opioid-related harms.
