title: [The musculoskeletal system load during work performed by nurse anesthetists].
abstract: BACKGROUND
  The aims of the survey was to analyze the musculoskeletal system load during work performed by nurse anesthetists and to identify activities involving poor work postures along with their causes.
  
  
  METHODS
  The observation process and the Ovako Working Posture Analysing System (OWAS) method were used as major tools of this survey. Altogether 57 observations of work process were made and 31 210 work postures were identified.
  
  
  CONCLUSIONS
  The results of the survey revealed the following average proportion of time spent by nurses performing basic work activities: preparation for anesthetization--20%; anesthetization--30%; cleaning--4%; other tasks--2%; and breaks at work--44%. The average propotion of time spend by nurse anesthetists in OWAS posture categories were: category 1--66%; category 2--30%; category 3--2%; and category 4--2%. The collected data show that the main causes of the musculoskeletal system load were poor work organization and technical factors.
