HEMODYNAMIC-EFFECTS OF PROPOFOL IN CHILDREN

The haemodynamic effects of induction of anaesthesia with propofol in children were studied. Two hundred and sixteen children (ASA 1) were randomly allocated to receive one of six different doses of propofol, from 1.6 mg/kg to 2.6 mg/kg, in 0.2 mg/kg increments. Noninvasive measurement of blood pressure showed that mean arterial pressure was reduced by approximately 15% after 1 minute, and by 30% after 5 minutes. The reduction in pulse rate over a 5‐minute period was approximately 17%. These changes were similar in each group, regardless of the dose administered. The propofol was mixed with lignocaine, 0.5 mg/ml, and the incidence of pain on injection into a vein on the dorsum of the hand was 24%. We conclude that, within the dose range of our study, the haemodynamic disturbance after induction of anaesthesia with propofol in children is not dose related. Copyright © 1991, Wiley Blackwell.
