Royal Brisbane Hospital, Division of Anaesthesiology and Intensive Care, University of Queensland, Brisbane, Australia.


We randomized 18 critically ill patients to receive ceftazidime 6 g/day by continuous infusion or bolus dosing (2 g 8 hourly), each with a loading dose of 12 mg/kg ceftazidime. During the first 8 h, plasma ceftazidime concentration fell below 40 mg/L in only one patient (trough 38 mg/L) from the infusion group, compared with eight from the bolus group (2-33 mg/L) for periods ranging from 73 to 369 min. Thereafter all infusion patients remained above 40 mg/L for 40 h of study versus 20-30% of bolus patients. The pharmacokinetic and pharmacodynamic characteristics of ceftazidime suggest that continuous infusions should be clinically investigated in outcome studies.
