Clinical Trial Controlled Clinical Trial
[Effects of different intramedullary stabilizing procedures of the femur on lung function in polytrauma].
We investigated the effects of primary (< 24 h) intramedullary femoral nailing on lung function and pulmonary hemodynamics in multiple trauma patients. The standard procedure following reaming of the medullary canal (AFN) was compared with a new procedure using a small, solid nail without prior reaming (UFN). Pulmonary hemodynamics were determined using a pulmonary artery catheter. ⋯ Our measurements did not show an increase in central venous triglycerides in the AFN group, probably because bone marrow does not become immediately soluble. There was no significant difference between the increase of elactase levels in the two groups. The femoral nailing procedure with reaming in multiple trauma patients involves a potential risk to the lung.(ABSTRACT TRUNCATED AT 250 WORDS)

Comparative Study
High-frequency jet ventilation for respiratory failure after congenital heart surgery.
Extracorporeal membrane oxygenation (ECMO) is considered when respiratory failure (RF) persists despite increasing conventional mechanical ventilation (CMV). High-frequency jet ventilation (HFJV) can improve ventilation with comparable mean airway pressure (PAW) to that found on CMV. This study was undertaken to determine whether HFJV is an effective treatment and alternative to ECMO for RF after congenital heart surgery. ⋯ This study suggests that HFJV improves ventilation and is an alternative to ECMO in patients with RF after surgery for congenital heart disease.

A sensitive and specific radioimmunoassay was used to measure interleukin 8 (IL-8) in bronchoalveolar lavage fluids from control subjects, patients with the adult respiratory distress syndrome (ARDS) and patients undergoing coronary bypass surgery, a risk factor for developing ARDS. Concentrations of IL-8, albumin, total protein and numbers of neutrophils were higher in both patient groups than in controls. ⋯ These data suggest that IL-8 may mediate the recruitment of neutrophils from the vascular compartment into the alveolar space and may therefore be an important determinant in neutrophil-mediated lung injury. Since increased levels of IL-8 were also found in BAL fluid from patients at risk in whom ARDS did not develop, other factors are likely to be involved and IL-8, as well as other markers of inflammation, are of little prognostic use.
