Data are presented as the mean (standard deviation) time (in minutes) from
termination of the propofol and remifentanil infusions to 50% loss of analgesia for
each dosing scheme. The remifentanil infusion was held constant at 0.2 mcg/kg/
min. A difference of 5 minutes was considered to be of clinical significance. |
