Randomized Controlled Trial
Comparison of Single-Operator Laser-Assisted Ultrasound-Guided Radial Arterial Cannulation in Young Children with Traditional Ultrasound Guidance: A Randomized Clinical Trial.
Radial artery cannulation in young children is challenging. A single-operator laser-assisted ultrasound-guidance system was invented to project the path of the target artery on the skin surface. The hypothesis was that this system would improve the first-attempt success rate of radial arterial cannulation in young pediatric patients relative to traditional ultrasound guidance. ⋯ Compared with traditional ultrasound guidance, the single-operator laser-assisted ultrasound-guided system is a useful add-on to the ultrasound dynamic needle-tip puncture technique. It improves the first-attempt success rate of radial artery cannulation in children younger than 2 yr by projecting the path of the artery on the skin and provides better procedural conditions (stable ultrasound probe).

Multicenter Study Observational Study
Prolonged Opioid Use and Pain Outcome And Associated Factors after Surgery Under General Anesthesia: A Prospective Cohort Association Multicenter Study.
There is insufficient prospective evidence regarding the relationship between surgical experience and prolonged opioid use and pain. The authors investigated the association of patient characteristics, surgical procedure, and perioperative anesthetic course with postoperative opioid consumption and pain 3 months postsurgery. The authors hypothesized that patient characteristics and intraoperative factors predict opioid consumption and pain 3 months postsurgery. ⋯ Preoperative opioid use was the strongest predictor of opioid use 3 months postsurgery. None of the other variables showed clinically significant association with opioid use at 3 months after surgery.

The association between growth differentiation factor-15 concentrations and cardiovascular disease has been well described. The study hypothesis was that growth differentiation factor-15 may help cardiac risk stratification in noncardiac surgical patients, in addition to clinical evaluation. ⋯ Growth differentiation factor-15 is strongly associated with 30-day risk of major cardiovascular events and significantly improved cardiac risk prediction in patients undergoing noncardiac surgery.
