title: Risk of vasovagal syndrome during outpatient hysteroscopy.
abstract: OBJECTIVE
  To evaluate influence of hysteroscope type and media used during outpatient hysteroscopy on vasovagal syndrome risk.
  
  
  METHODS
  Prospective observational study (Canadian Task Force classification II-1).
  
  
  METHODS
  University hospital.
  
  
  METHODS
  Two thousand seventy-nine women undergoing outpatient hysteroscopy without analgesia.
  
  
  METHODS
  Office hysteroscopy with a flexible or rigid hysteroscope and normal saline or CO(2).
  
  
  RESULTS
  Fifteen cases of vasovagal syndrome were reported. The rate of vasovagal syndrome was higher with use of a rigid hysteroscope (12/647 [1.85%]) vs. a flexible hysteroscope (3/1432 [0.21%]), p =.00013; p =.009 after adjustment for medium used; and with the use of CO2 (10/426 [2.34%]) vs. saline solution (5/1653 [0.30%]), p <.0001; p =.014 after adjustment for hysteroscope type.
  
  
  CONCLUSIONS
  Risk of vasovagal syndrome is higher with the use of a rigid hysteroscope and CO2, regardless of the indication for hysteroscopy or the parity and menopausal status of the patient.
