Current guidelines outlining the resuscitation of severely burned patients, in the United States, were developed over 30 years ago. Unfortunately, clinical burn resuscitation has not advanced significantly since that time despite ongoing research efforts. Many formulas exist and have been developed with the intention of providing appropriate, more precise fluid resuscitation with decreased morbidity as compared to the current standards, such as the Parkland and modified Brooke formulas. The aim of this review was to outline the evolution of burn resuscitation, while closely analyzing current worldwide guidelines, adjuncts to resuscitation, as well as addressing future goals.
In severely burned military casualties undergoing initial burn resuscitation, the modified Brooke formula resulted in significantly less 24-hour volumes without resulting in higher morbidity or mortality.
Elastic recoil of the vessel wall is a common cause of failure of percutaneous transluminal angioplasty in renal arteries. To oppose such recoil, balloon-expandable metal stents were implanted in artificially stenotic renal arteries in pigs and normal renal arteries in dogs and pigs. The stents were then examined angiographically and histologically at regular intervals. All stents were completely covered with endothelialized neointima in 3 weeks. There was no difference in intimal thickness between the stenotic and nonstenotic renal arteries. A large stent diameter and a large open or nonmetal surface may cause less intimal hyperplasia, but nonturbulent, fast arterial flow is probably the most important factor in ensuring long-term patency of the vessel.
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.
