Filter by:The aim of this study is to determine the minimum effective volume of lidocaine in 90% of patients (ED90) required for single-injection US-guided costoclavicular infraclavicular.
The aim of this randomized, observer-blinded study is to evaluate the postoperative analgesic efficacy of adding dexamethasone and clonidine to ropivacaine in supraclavicular nerve block. The investigators hypothesized that addition of dexamethasone and clonidine to ropivacaine would prolong the duration of analgesia in supraclavicular nerve block compared with ropivacaine alone.
This is a research study to determine if the effects of continuous peripheral nerve blocks are influenced by the distance of insertion past the needle tip of the perineural catheter.
This research study is to determine if the insertion site of a perineural catheter or tiny tube placed next to the nerves that go to the part of the body (hand or arm) having surgery, affects the amount of pain relief that is experienced after surgery. Catheters will be placed in either the supraclavicular or infraclavicular location.
