title: [Investigation of the neck swelling due to accumulation of irrigation fluid during shoulder arthroscopy in the beach-chair position].
abstract: BACKGROUND
  The primary purpose of this study was to investigate the degree of neck swelling by accumulation of irrigation fluid during shoulder arthroscopy in the beach-chair position.
  
  
  METHODS
  Twenty-one patients undergoing shoulder arthroscopy in the beach-chair position were included in this study. There were 16 male and 5 female patients, with a mean age of 58.7 +/- 16.1 years. All patients' weight and neck circumference were compared pre- and postoperatively and correlated to each other.
  
  
  RESULTS
  There was a strong correlation between the increase rate of weight and the increase rate of neck circumference (r = 0.69, P < 0.05).
  
  
  CONCLUSIONS
  Pre- and postoperative measurement of the neck circumference might be an easy and useful measure for prediction of postoperative airway obstruction.
