Venous flow pattern changes and venous flow were assessed in relation to the degree of hemodilution. Femoral vein flow was measured with a duplex scanner in two groups of 11 patients 20 days and 5 days preoperatively, and 1 day postoperatively. In group I, hemodilution was used and patients gave three autologous blood predonations between day 20 and day 5. Perioperative blood loss was reintegrated by electrolyte solution. In group II, hemodilution was not used and autologous blood predonations were not carried out. These patients received a perioperative homologous blood transfusion of 800 mL. Hemoglobin was lower on day 5 (11.3 +/-1.4 vs 13.1 +/-1 g/dL, p<0.05) and on postoperative day 1 (8.9 +/-1.6 vs 10.6 +/-1, p<0.05) in group I. The decrease in hemoglobin was associated with an increase in blood flow and a pulsed venous flow pattern in 14 of 22 veins after autologous blood predonation and in 21 of 22 veins on postoperative day 1 (p<0.05). Increased venous flow in hemodilution is associated with a pulsed venous flow pattern.

Evaluation of prognostic significance of circulating interleukin-6 in patients with accident spine injuries.

Our study aimed to verify whether patients with spine accident injury present altered plasma levels of IL-6 and whether the levels of this cytokine are related with the production of acute phase proteins which are elevated after trauma and infection. 34 subjects admitted to an Intensive Care Unit for spine injuries were examined: 26 presented fever over 38.5 degrees C and in 13 of them blood or local cultures were positive for pathogenic bacteria. IL-6, C-reactive protein (CRP), haptoglobin (HPT), alpha 2-macroglobulin (alpha 2Mg), C3c and C4 Complement factors were determined on admission and in the course of their hospital stay. No changes in IL-6 systemic levels were present in the subjects examined and only CRP was constantly high. Although within the normal range IL-6 levels inversely correlated with fever. Our results show the difficulty to utilize the IL-6 circulating levels as prognosis parameter in patients subjected to spine accident injuries.

Associated lesions in multiple trauma of the pelvis. Diagnostic and therapeutic considerations.

On the basis of 80 cases of traumatic lesion of the pelvis with associated vascular and visceral lesions, observed between 1985 and 1994 at the Department of Surgery in Modena and at the Rizzoli Orthopaedic Institute in Bologna, the options for diagnosis as related to the specificity of lesions are examined, and the choices of indications and surgical technique are illustrated.
