BACKGROUND Major improvements have been made in the development of novel dressings with hemostatic properties to control heavy bleeding in noncompressible areas. To test the relative efficacy of different formulations in bleeding control, recently manufactured products need to be compared using a severe injury model. METHODS Ten hemostatic dressings and(More)
OBJECTIVE Many patients with primary hyperparathyroidism either decline or are not candidates for surgical parathyroidectomy. There are drawbacks to medical therapy as well as percutaneous ethanol injection as alternative therapies for primary hyperparathyroidism. Therefore, in this pilot study, our aim was to test the feasibility, safety, and efficacy of a(More)
HBOC-201, a bovine polymerized hemoglobin, has been proposed as a novel oxygen-carrying resuscitative fluid for patients with hemorrhagic shock (HS). Herein, we evaluated the hemostatic effects of HBOC-201 in an animal model of HS. A 40% blood loss-controlled hemorrhage and soft tissue injury were performed in 24 invasively monitored Yucatan mini-pigs. Pigs(More)
The permeability of human platelets to glycerol (GLY) and propane-1,2-diol (propylene glycol, PG) has been determined by measuring the time course of their change in volume following abrupt immersion in solutions of these solutes. A simple light-scattering method, and its calibration to measure mean platelet volume is described. The data are analyzed by(More)
OBJECTIVE To test our hypothesis that hemoglobin-based oxygen carrier (HBOC)-201 resuscitation in hemorrhagic shock (HS) will not lead to increased organ injury and dysfunction. DESIGN Three swine HS models simulating military-relevant delayed evacuation: a) moderate controlled HS, b) severe controlled HS, and c) severe uncontrolled HS. SETTING Military(More)
Background Zeolites have hemostatic properties used to stop bleeding in severe hemorrhage. Manufactured QuikClot® is an approved zeolite-based hemostatic agent for battlefield use. The exothermic reaction associated with QuikClot as loose granules or as granules packaged in a mesh bag has potential burn effects; this led to the development of a formulation(More)
The purpose of this investigation was to compare the effects of initial resuscitation with HBOC-201 to that of lactated Ringer (LR) solution in the setting of uncontrolled hemorrhage and traumatic brain injury (TBI). Anesthetized immature swine underwent fluid-percussion TBI and liver laceration. During a 75-min "prehospital phase," the animals were(More)
BACKGROUND The recently developed non-invasive high-intensity focussed ultrasound (HIFU) technique for the destruction of parathyroid adenomas could also be of interest for the treatment of secondary hyperparathyroidism (SHP) in patients with chronic kidney disease (CKD). We conducted a pilot study using this method. METHODS Five chronic haemodialysis(More)
BACKGROUND QuikClot is a zeolite-based dressing approved and deployed by military for the arrest of severe combat-induced hemorrhage. A novel formulation (bagged QuikClot [ACS]) of the original granular QuikClot (QC) has been proposed to facilitate the application of the hemostatic dressings under battlefield conditions. This study compares the hemostatic(More)
