The bolus dose of 0.2 % ropivacaine using US-guided CBPB would provide equivalent analgesic efficacy comparable with the basal infusion and motor weakness comparable with IV-PCA after arthroscopic rotator cuff repair.
Certain oral surgery can be performed safely under monitored anesthesia care (MAC) with local anesthesia. Several drugs, such as propofol, benzodiazepine, and opioids have been used for MAC either alone or in combination. Benzodiazepine may cause excessive sedation and confusion, and propofol can also result in disorientation and excessive sedation. Low dose propofol anesthesia with the concomitant use of dexmedetomidine is an effective technique for MAC in patients who are scheduled for intraoral surgery.
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.
