Talc pleurodesis was performed in a prospective trial in 38 patients with recurrent malignant pleural effusion. After insertion of a chest tube a slurry containing 8g of iodined talcum, 0.5 ml of 1% xylocain/kg/body weight, and 80 ml of 0.9% NaCl was administered and suction drainage was performed. ⋯ A successful therapy could be achieved in 33/38 patients (86.8%). 2 patients (5.3%) suffered from recurrent pleural effusion which only in 1 case had to be drained. 3 patients died within the first month after talc pleurodesis due to an advanced cancer stage. Complications did not come to evidence in any case.

Our previous studies in isolated rat hindlimbs using crystalloid perfusion solutions have shown that control of the initial reperfusion reduces postischemic complications. However, no experimental study has been undertaken to evaluate the concept of controlled limb reperfusion experimentally in an in-vivo blood-perfused model and to assess the local as well as systemic effects of normal blood reperfusion and controlled limb reperfusion. Of twenty pigs undergoing preparation of the infrarenal aorta and iliac arteries, six were observed for 7.5 hours and served as controls. ⋯ Furthermore, controlled limb reperfusion resulted in higher total adenine nucleotides content (78% vs. 57% of control), less tissue acidosis (6.6 +/- 0.2 vs. 5.9 +/- 0.1, p < 0.002), severely reduced CK release (2,618 +/- 702 vs. 12,743 +/- 2.562, p < 0.02) and potassium release (5.1 +/- 0.3 vs. 7.9 +/- 0.3 mmol/L, p < 0.0002) as compared to normal blood reperfusion. In conclusion this study shows that 6 hours of acute infrarenal aortic occlusion will result in a severe reperfusion injury (postischemic syndrome) if normal blood at systemic pressure is given in the initial reperfusion phase. In contrast, initial treatment of the ischemic skeletal muscle by controlled limb reperfusion reduces the metabolic, functional and biochemical alterations.

Review Comparative Study
[Value of clinical scoring systems for evaluation of injury severity and as an instrument for quality management of severely injured patients].
Trauma Score Systems attempt to summarize the severity of injury in a single value. They provide a better classification of trauma patients and translate different severities of injury in a common language. They enable thereby comparisons between hospitals or trauma systems. ⋯ Glasgow Coma Scale, Revised Trauma Score, Injury Severity Score and TRISS are the most often used international scores for severely injured patients. Their sensitivity and specificity, validity, reliability and practicability have been studied and proved in many trials. The role of these scoring systems for quality management purposes in the treatment of severe trauma is actually studied with the Trauma Registry of the German Society for Trauma Surgery.

Sequential organ failure after multiple trauma emerges from a whole-body inflammatory process which develops as a complex host defense response to hypovolemic shock/resuscitation and traumatic tissue injury. Successful prevention and treatment involves exact assessment of inflicted damage and profound knowledge of the different stages of posttraumatic immune alterations. Local release of potent inflammatory mediators (cytokines, complement, arachidonic acid derivatives, reactive oxygen metabolites) primarily induces a repair process. ⋯ Diffuse capillary leakage and microcirculatory disorder prepare cellular dysfunction. Secondary severe immune defects support septic complications which maintain an autodestructive process. Therapeutical advances depend on the analysis of local and time-dependent expression of relevant inflammatory mediators and cellular signalling systems.
