A novel, cassette-based nitric oxide delivery system with an advanced feedback control algorithm accurately delivers nitric oxide via the anesthesia machine independent of fresh gas flow rate and volatile anesthetic agent.
Nitric oxide (NO), a selective pulmonary vasodilator, can be delivered via conventional ICU and anesthesia machine ventilators. Anesthesia machines are designed for rebreathing of circulating gases, reducing volatile anesthetic agent quantity used. Current cylinder- and ionizing-based NO delivery technologies use breathing circuit flow to determine NO delivery and do not account for recirculated gases; therefore, they cannot accurately dose NO at FGF below patient minute ventilation (MV). ⋯ GENOSYL® DS maintained accurate NO delivery with all three anesthesia machines, at low FGF with recirculation of gases, and with all volatile anesthetic agents at different concentrations. Measured NO2 levels remained acceptable at ≤ 1 ppm with set NO dose ≤ 40 ppm. GENOSYL® DS, with its advanced feedback control algorithm, is the only NO delivery system capable of accurately dosing NO with anesthesia machines with rebreathing ventilation parameters (FGF < MV) regardless of anesthetic agent.

Meta Analysis Comparative StudyComparison between hemodynamic effects of remimazolam and propofol during general anesthesia: a systematic review and meta-analysis.
The need for safe anesthetic agents with minimal side effects has led to the development of remimazolam, a new benzodiazepine designed to be an alternative to the commonly used drug propofol, which has significant hemodynamic effects. This study aims to compare the hemodynamic effects of remimazolam with propofol during general anesthesia. ⋯ This study provides evidence that remimazolam induces fewer cardiorespiratory depressant effects and has a more favorable side effect profile compared to propofol during general anaesthesia.

Randomized Controlled Trial Comparative Study
Addition of liposomal bupivacaine to standard bupivacaine versus standard bupivacaine alone in the supraclavicular brachial plexus block: a randomized controlled trial.
The analgesic effect of adding liposomal bupivacaine to standard bupivacaine in supraclavicular brachial plexus block is not known. The authors hypothesized that addition of liposomal bupivacaine would reduce acute postoperative pain compared to standard bupivacaine alone. ⋯ Liposomal bupivacaine given via supraclavicular brachial plexus block reduced pain at rest in the early postoperative period.
