The objective of this study was to test the hypothesis that after hemorrhagic hypotension, reinfusion of the shed blood with threefold that volume of lactated Ringer's (LR) solution will significantly increase lung water and venous admixture and hence decrease systemic arterial oxygen saturation. A prospective, randomized, fixed-volume hemorrhage laboratory study was performed at the Oklahoma University Health Sciences Center on 18 anesthetized mongrel dogs. ⋯ However, lung water, venous admixture, and systemic arterial PO2 were similar between groups. In this fixed-volume hemorrhage model, hemodiluting the reinfused shed blood with threefold the volume of LR did not significantly influence lung water, venous admixture, or systemic arterial oxygen saturation.

Infection control for health care workers caring for critically injured patients: a national survey.
Prevention of transmission of bloodborne pathogens to health care workers (HCWs) involved in resuscitation of critically injured patients presents special challenges. As a step toward creation of a standard, a telephone survey of the infection control practices in this setting of the 100 busiest EDs in the United States (US) was performed. Departmental staff who were knowledgeable about ED infection prevention protocols were questioned about general policy, barrier protection measures, sharps management, and educational programs directed to HCWs. ⋯ Only 59 EDs (72%) reported that sharp containers were always within arm's reach of HCWs with material to discard. Specially adapted equipment included self-sheathing intravenous catheters (21, 26%) and needle/syringe combinations (16, 20%). Considerable variation exists in infection control practices in busy US EDs during resuscitation of critically injured patients.(ABSTRACT TRUNCATED AT 250 WORDS)
