Perflubron emulsion (AF0144) augments harvesting of autologous blood: a phase II study in cardiac surgery.

Objective: To assess tolerance and preliminary efficacy of a perfluorocarbon emulsion (AF0144) used with acute normovolemic hemodilution to reduce allogeneic blood transfusion for patients undergoing coronary artery bypass graft (CABG) surgery with cardiopulmonary bypass (CPB).

Design: Controlled, single-blind, parallel-group phase II dose escalation trial.

Setting: Single-institution university medical center.

Randomized safety studies of intravenous perflubron emulsion. II. Effects on immune function in healthy volunteers.

Particle size distribution is a major determinant of particle clearance by the mononuclear phagocytic system and the potential for concomitant activation of resident macrophages. To test the safety of a second-generation perflubron-based emulsion (60% perfluorocarbon [PFC] wt/vol; Oxygent [Alliance Pharmaceutical Corp., San Diego, CA]) with a small mean particle size, two parallel, randomized, double-blinded, placebo-controlled studies were conducted in 48 healthy volunteers (n = 24 per study).

Randomized safety studies of intravenous perflubron emulsion. I. Effects on coagulation function in healthy volunteers.

Previous perfluorocarbon (PFC) emulsions have been associated with transient adverse events (i.e., platelet activation, decreased platelet count, febrile responses, changes in hemodynamic function).

A pilot study of the effects of a perflubron emulsion, AF 0104, on mixed venous oxygen tension in anesthetized surgical patients.

A pilot study of a perfluorochemical (PFC) emulsion was undertaken to determine whether administration of a perflubron emulsion could result in measurable changes in mixed venous oxygen tension. Seven adult surgical patients received a 0.9-g PFC/kg intravenous dose of perflubron emulsion after acute normovolemic hemodilution (ANH).
