title: Results of thoracic drainages placed in air rescue.
abstract: BACKGROUND
  horax injuries are to be found in approximately 78% amongst all accident victims. Moreover, they implicate an increase in mortality rate. Consequently, an adequate contemporary treatment has to begin preclinically, even if the conditions are less comfortable than in a clinical setting. Emergency doctors need to be familiar with the placement of chest tubes.
  
  
  METHODS
  From January 1, 2007 to December 31, 2010, emergency doctors of the rescue helicopter site Christoph 20 had to place chest tubes directly at the scene of an accident in 49 patients. These patients were now reidentified, and their clinical course was reevaluated. By means of apparative diagnostics, it was possible to analyze the location of the tubes tip. Following a comparison of the patient, outcome versus the quality of preclinical thoracic discharge could be made.
  
  
  RESULTS
  The preclinical placement of a chest tube became necessary mainly because of a blunt thoracic trauma. This was predominantly related to victims of traffic accidents, whereas male victims clearly dominated. Forty-two of those patients received further treatment at the Klinikum Bayreuth hospital, enabling an analysis of the tubes location by CAT (computed axial tomography) scan. Six patients had been discharged on both sides, contributing to 48 tube tips that could be examined concerning their location. Of the 48 chest tubes, 46 had been placed from a lateral approach. The ventral access by Monaldi had only been chosen in two cases. Altogether, nine incorrect placements, mainly within the right interlobe gap, had been detected.
  
  
  CONCLUSIONS
  The study collective showed a significant preference to the lateral approach when placing a chest tube at the emergency scene of an accident. In total, a prevalence of 19% incorrect placements could be revealed, meaning the chest tube had either been placed within the lung parenchyma, the interlobe gap, or extrathoracically. Concerning the patient outcome, no statistically significant difference regarding the clinical course after incorrect chest tube placement could be identified.
