We have investigated the pharmacokinetics and pharmacodynamics of propofol
in 11 patients with end-stage renal disease (ESRD) compared with nine
healthy patients during and after a manually controlled three- stage
infusion of propofol 21, 12 and 6 mg kg-1 h-1 lasting a minimum of 2 h.
Mean total body clearance was not reduced significantly in the ESRD group
(30.66 (SD 8.47) ml kg-1 min-1) compared with the control group (33.75
(7.8) ml kg-1 min-1). ESRD patients exhibited a greater, but not
statistically significant, volume of distribution at steady state compared
with patients in the control group (11.25 (8.86) vs 5.79 (2.14) litre kg-1,
respectively). Elimination half-life values were unchanged by renal
failure. Mean times to induction of anaesthesia were similar in both
groups: 177 (SD 57) and 167 (58) s for the ESRD and control groups,
respectively. Waking time after cessation of propofol infusion was
significantly shorter in the ESRD group (474 (156) s) compared with the
control group (714 (240) s) (P < 0.05). Mean plasma concentrations on
waking were similar. We conclude that the pharmacokinetic and
pharmacodynamic profiles of propofol after infusion were not markedly
affected by renal failure.
