AbstractIntravenous propofol and remifentanil are often used in anesthesia. The combined use of these drugs tends to cause hemodynamic depression. We describe the absence of hemodynamic effects in response to infusion of propofol and remifentanil when hydroxyethyl starch (HES) 130/0.4 was also administered. During induction, because blood volume needed to be replaced, two patients aged 62 and 65 years received intravenous HES 130/0.4. They then received a single dose of 2 microg x kg(-1) of remifentanil during total intravenous anesthesia (TIVA) with propofol and remifentanil before placement of a Mayfield head holder. No changes in mean blood pressure or heart rate were observed in either patient after the remifentanil bolus when they have received HES 130/0.4 during TIVA with propofol and remifentanil HES 130/0.4 may play an active role in preventing a hemodynamic response to remifentanil bolus. This hypothesis should be tested in a randomized controlled trial.
