Factors Affecting Tissue Oxygenation in Erythrocyte Transfusions.

Red blood cell transfusions are used to increase the oxygen-carrying capacity of blood in anemic states. But, because of the changes during storage of blood components and the specifics of preparation, erythrocytes may have controversial effects on tissue oxygenation and microcirculation. Also, the patient situation may play a role in the differing responses in oxygenation and microcirculation....

Assessing tissue oxygenation.

Although physical examination remains an important part of the nursing assessment, assessment of tissue oxygenation provides additional vital information. Nurses who are caring for patients with compromised functioning must have a basic understanding of the physiological relationships between oxygen saturation, cardiac output, and acid-base balance and must be able to plan nursing care based on...

Hypercapnia improves tissue oxygenation.

BACKGROUND Wound infections are common, serious, surgical complications. Oxidative killing by neutrophils is the primary defense against surgical pathogens and increasing intraoperative tissue oxygen tension markedly reduces the risk of such infections. Since hypercapnia improves cardiac output and peripheral tissue perfusion, we tested the hypothesis that peripheral tissue oxygenation increase...

[Local recurrence in soft tissue sarcoma: prognostic factors].

OBJECTIVE To determinate the prognostic factors associated with the local relapse in patients treated for soft tissue sarcoma in extremities. METHODS Retrospectively, 30 patients were evaluated after being treated with surgical resection of soft tissue sarcoma located in extremities, with a outcome of 36,5 +/- 12,2 months. The prognostic factors evaluated were: age, sex, location, depth, loca...
