title: The incidence of asystole in patients undergoing strabismus surgery.
abstract: OBJECTIVE
  To investigate the incidence of asystole during strabismus surgery.
  
  
  METHODS
  Retrospective, noncomparative interventional case series.
  
  
  METHODS
  Six months to 80 years of age of 3628 consecutive patients who underwent strabismus surgery from October 1994 to May 2007 were enrolled.
  
  
  RESULTS
  Four patients (0.11%) under general anaesthesia showed asystole during strabismus surgery. All four were adults of 28, 32, 50, and 53 years of age. Two patients had hypertension and three had preoperative electrocardiographic abnormalities. Three patients had previously undergone uneventful strabismus surgery.
  
  
  CONCLUSIONS
  Asystole is likely to be encountered during strabismus surgery with an incidence of ca. 0.11%.
