title: [Effect of propofol and propofol combined with ketamine on cardiovascular system].
abstract: OBJECTIVE
  To prevent blood pressure from reducing caused by injection of propofol.
  
  
  METHODS
  Thirty patients, ASA Grade I-II, were randomly allocated into one of the two groups: Group I (Group P, n = 15) and Group II (Group K + P, n = 15), the patients received 2 mg.kg-1 propofol in Group I and 1 mg.kg-1 ketamine before equal dose of propofol in Group II. Systolic blood pressure(SBP), diastolic blood pressure(DBP), mean blood pressure and heart rate were measured before injection and 1 min, 3 min, 5 min and 10 min respectively after injection.
  
  
  RESULTS
  Blood pressure in Group I was significantly lower than Group II.
  
  
  CONCLUSIONS
  Ketamine can attenuate the hemodynamic responses to propofol.
