Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
Effect of 1% and 2% propofol on blood lipids during longterm sedation.
To compare the effects of 1% and 2% propofol on the maximum and average lipid levels, the relative frequency of hyperlipidaemia, the propofol dose required to achieve an equivalent degree of sedation, the pharmacodynamic effects at the required infusion rates, and the effect on respiratory function. ⋯ Seventy-five patients were enrolled in the study, of which 72 were evaluable for safety analysis and 58 were evaluable for efficacy analysis. The total daily dose of propofol (ml/day) in the 2% propofol group was about 60% of that in the 1% propofol group, indicating that the lipid load in the 2% propofol group had only slightly more than half the lipid load in the 1% propofol group. Thirteen of 27 patients (48%) in the 2% propofol group had abnormally.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
Remifentanil vs morphine for patients in intensive care unit who need short-term mechanical ventilation.
This randomized, double-blind study compared the safety and efficacy of remifentanil (9 microg/ kg/h) with morphine (0.045 mg/kg/h plus a bolus dose of 0.025 mg/kg). One hundred and eighty nine Intensive Care Unit (ICU) patients with normal renal function or mild renal impairment requiring mechanical ventilation were included in this study. A pre-defined dosing algorithm permitted initial titration of the opioids to predetermine the optimal level of sedation and pain score. ⋯ The dosing algorithm facilitated rapid extubation in both groups. Remifentanil provided comparable hemodynamic stability to morphine, and was not associated with an increase in cardiovascular adverse event. Remifentanil is therefore considered to be effective and well tolerated in ICU patients.

Randomized Controlled Trial Multicenter Study Clinical TrialA dose-ranging study of midazolam for postoperative sedation of patients: a randomized, double-blind, placebo-controlled trial.
To evaluate the dose range, efficacy, and safety of midazolam for induction of sedation of mechanically ventilated postoperative patients in the intensive care unit. ⋯ The proportion of patients who achieved a satisfactory level of sedation increased with an increasing dose of midazolam. Intravenous bolus injection of midazolam also dose-dependently reduced mean systolic arterial pressure. This study indicated that, balancing sedative efficacy and safety, from 0.03 to 0.06 mg/kg of midazolam provides relatively safe sedation in postoperative patients.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical TrialRemifentanil sedation compared with propofol during regional anaesthesia.
The short onset and offset of remifentanil may allow for accurate dosing of sedative effect with few side-effects and rapid recovery. In this study remifentanil is compared with propofol for sedation during successful regional anaesthetic blocks. ⋯ Propofol results in less respiratory depression and nausea when sedation is needed during a case with a successful regional block. Remifentanil may be considered as an alternative if pain during the procedure is a major concern or if amnesia is contraindicated.

Randomized Controlled Trial Multicenter Study Clinical Trial
Economic evaluation of propofol for sedation of patients admitted to intensive care units.
The goal of the current study was to evaluate the economic impact of propofol as compared with midazolam for sedating patients in the intensive care unit (ICU). ⋯ The analysis demonstrated that using propofol resulted in a reduction of time to extubation and higher sedative regimen costs. There was no difference in intensity of resource use or ICU length of stay and hence in costs. Issues regarding discharge delay among propofol-treated patients remain to be explored.
