简要总结
The purpose of this study is to determine whether the addition of dexamethasone prolongs analgesia when added to long-acting local anesthetic during single-injection supraclavicular block for outpatient hand surgery.
详细描述
The goal for pain control after surgery is to provide the best possible pain control for the longest period of time with the least amount of side effects. One type of pain medication is called local anesthetic, which is a numbing medication that is injected in the area surrounding nerves to block pain. This injection is called a nerve block. Ropivacaine is a local anesthetic that is commonly used for nerve blocks and will be used in this study. The effects of ropivacaine may last for 8 to 12 hours after surgery. Recent research studies have shown that adding a medication called dexamethasone (a steroid) may increase the time that the nerve block will provide pain control. The purpose of this study is to see if adding dexamethasone to ropivacaine and injecting this around the nerves during a supraclavicular brachial plexus block increases the duration of pain relief as compared to both placebo control and systemic control groups.
