[Reconstruction in polytraumatized burn patients]. / Rekonstruktion beim polytraumatisierten Brandverletzten.

BACKGROUND: Polytraumatized burn patients represent a rare patient collective and necessitate an individualized treatment concept due to the particular combination of injuries. OBJECTIVE: Against the background of this special injury pattern, especially with deep burns overlying the fracture zone, the question of a specific and interdisciplinary treatment algorithm arises. MATERIAL AND METHODS: This article is based on a PubMed database search and experiences of a trauma center for severely injured burn patients at a university hospital, with presentation of the special therapeutic requirements and goals exemplified by a case report. RESULTS: The evaluation of the literature search and own treatment results comes to the conclusion that the rate and extent of amputations and infections can be reduced by an early and interdisciplinary involvement of the plastic surgeon by early combined fracture stabilization, excision of necrotic tissue and immediate skin grafting. Furthermore, plastic reconstructive procedures enable a functional and esthetic reconstruction with optimized prosthesis fitting. CONCLUSION: Polytraumatized severely burned patients necessitate an interdisciplinary treatment approach, whereby preservation of length, functionality and esthetic appearance of the affected extremities and concurrent avoidance of bone and soft tissue infections have utmost priority.

A pot evaluation of the sensitivity of spring barley (Hordeum vulgare L.) to water stress applied at different growth stages.

Two-year pot experiments with three varieties of spring barley were carried out. Water stress (water deficit of soil up to 40% of field water-holding capacity) was employed in four basic growth stages of plants: tillering, shooting (stem extension stage), ear formation and milk maturity. Reactions of the plants to water stress were expressed by a decline in the grain yield of the studied varieties throughout the growing season. The greatest losses in production of spring barley grain due to the experienced water stress of the plants were found at the beginning of ear formation and milk maturity stages of the grain. The sensitivity of the plants to the stress caused by water deficit in the soil during the initial period of their vegetative growth was smaller. Varieties showed significantly different sensitivities to the experienced water stress, depending on the growth stage during which the plants suffered from the stress.
