The authors concluded that 10% magnesium sulfate applied locally has the best ability to relieve surgically induced vasospasm because of the highest level of significance and reliability. The finding that local application of 2% lidocaine prolongs vasospasm may be surprising.
We describe our experience and outcome with the 'Proximal first dorsal metacarpal artery free flap'. Ten consecutive cases utilizing the proximal first dorsal metacarpal artery free flap for complex digital defects were studied. Surgical technique, patient demographics, and flap outcome data were collected. Patient satisfaction was analysed using a questionnaire. All defects healed successfully with no loss of free flaps. The short-pedicle proximal first dorsal metacarpal artery free flap enables primary closure of the donor site up to 2 cm of width (in nine of the ten donor sites). The flap is a reliable and versatile alternative in selected cases of complex digital injuries.
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.
