Multicenter Study Observational StudyAlarm Limits for Intraoperative Drug Infusions: A Report From the Multicenter Perioperative Outcomes Group.
Continuous medication infusions are commonly used during surgical procedures. Alarm settings for infusion pumps are considered important for patient safety, but limits are not created in a standardized manner from actual usage data. We estimated 90th and 95th percentile infusion rates from a national database for potential use as upper limit alarm settings. ⋯ Alarm settings based on infusion rate percentile limits would be triggered at predictable rates; ie, the 95th percentile would be exceeded and an alarm sounded during 1 in 20 infusion rate entries. As a result, institutions could establish pump alarm settings consistent with desired alarm frequency using their own or externally validated usage data. Further study will be needed to determine the optimal percentile for infusion alarm settings.

Randomized Controlled Trial Multicenter Study Comparative StudySingle-Injection Versus Multiple-Injection Technique of Ultrasound-Guided Paravertebral Blocks: A Randomized Controlled Study Comparing Dermatomal Spread.
The objective of this study was to investigate the extent of dermatomal spread following an ultrasound-guided thoracic paravertebral block (PVB) when equal volumes of local anesthetic are injected at 1 versus 5 vertebral levels. ⋯ An ultrasound-guided single-injection PVB provides equivalent dermatomal spread and duration of analgesia compared with a multiple-injection PVB. The single-injection technique takes less time to perform and hence may be preferred over a multiple-injection technique.The trial was registered prospectively at ClinicalTrials.gov (NCT02852421) on July 15, 2016.

Randomized Controlled Trial Multicenter StudyMinimum Effective Volume of Lidocaine for Ultrasound-Guided Costoclavicular Block.
This dose-finding study aimed to determine the minimum effective volume in 90% of patients (MEV90) of lidocaine 1.5% with epinephrine 5 μg/mL for ultrasound-guided costoclavicular block. ⋯ For ultrasound-guided costoclavicular block, the MEV90 of lidocaine 1.5% with epinephrine 5 μg/mL is 34 mL. Further dose-finding studies are required for other concentrations of lidocaine, other local anesthetic agents, and multiple-injection techniques.

Multicenter StudyEfficacy and safety of 5% lidocaine-medicated plasters in localized pain with neuropathic and/or inflammatory characteristics: an observational, real-world study.
Based on clinical study results, 5% lidocaine-medicated plaster (5% LMP) is currently recommended for the treatment of localized peripheral neuropathic pain, such as post-herpetic neuralgia (PHN). However, its effective action, as well as the high safety, have indeed led to its use in clinical practice for pain conditions with similar pathophysiological mechanisms. In this study, the efficacy and safety of 5% LMP were investigated in patients with localized pain with neuropathic and/or inflammatory characteristics, such as PHN, post-traumatic/surgical or musculoskeletal pain. ⋯ The effectiveness and safety of 5% LMP were shown in localized pain conditions such as neuropathic and, importantly, in musculoskeletal pain, a condition never investigated with this product. This field-practice study suggests that topical pain-reducing strategies such as 5% LMP could be effective in neuropathic and/or inflammatory, localized pain conditions.

Randomized Controlled Trial Multicenter Study
Effect of Levosimendan on Low Cardiac Output Syndrome in Patients With Low Ejection Fraction Undergoing Coronary Artery Bypass Grafting With Cardiopulmonary Bypass: The LICORN Randomized Clinical Trial.
Low cardiac output syndrome after cardiac surgery is associated with high morbidity and mortality in patients with impaired left ventricular function. ⋯ Among patients with low ejection fraction who were undergoing coronary artery bypass grafting with cardiopulmonary bypass, levosimendan compared with placebo did not result in a significant difference in the composite end point of prolonged catecholamine infusion, use of left ventricular mechanical assist device, or renal replacement therapy. These findings do not support the use of levosimendan for this indication.
