Operative and postoperative wound infiltration with multimodal drugs reduces pain and the requirement for analgesics after hip replacement, leading to faster postoperative mobilization.
The effects of addition of 1 ml of lignocaine (10 mg) or isotonic saline to 19 ml of the emulsified preparation of propofol (Diprivan) were studied in a randomised, double-blind trial in 80 patients. The incidence and severity of pain on injection of propofol were significantly reduced by the addition of lignocaine (P less than 0.01).
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.
