Small-dose S(+)-ketamine had no positive effect on postoperative analgesia when administered perioperatively for elective arthroscopic anterior cruciate ligament repair. Unlike investigations of the racemic mixture of ketamine, our study methods included timely standard-practice perioperative opioid analgesia, which seems to make supplemental analgesia unnecessary.
Since the 1998 Olympic Winter Games in Nagano, snowboarding has been established as a popular winter sport for youth and adults. The most frequently affected body region reported in many studies on snowboarding injuries are the wrists accounting for more than 50% of severe injuries, especially in beginners. Wrist braces are effective in protecting snowboarding beginners against wrist injuries. Male snowboarders up to the age of 16 and female snowboarders over the age of 25 have a higher risk of injury. Snowboarders should not use ski boots and should be careful with rented equipment. Systems providing body and limb protection and also snowboard-specific helmets can reduce the injury risk for alpine racers, freestylers, and also freeriders. Snowboard training is important to prevent injuries especially for beginners, and icy slopes should be avoided.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
