Fospropofol disodium versus propofol for long-term sedation during invasive mechanical ventilation: A pilot randomized clinical trial - 25/04/24
Abstract |
Study objective |
Fospropofol disodium is a propofol prodrug that is water-soluble and has a reduced risk of bacterial contamination and hypertriglyceridemia compared with propofol. Prior to implementing a large randomized trial, we investigated the feasibility, initial efficacy, and safety of fospropofol disodium compared with propofol in long-term mild-to-moderate sedation in intensive care units (ICUs).
Design |
Single-centered, prospective, unblind, randomized, parallel-group clinical trial.
Setting |
The general ICU of university-affiliated teaching hospital.
Patients |
Adult patients (n = 60) expected to have mechanical ventilation for >24 h were enrolled and randomly assigned to the fospropofol or propofol group.
Interventions: The fospropofol group received continuous fospropofol disodium infusions and the propofol group received continuous propofol infusions. The sedation goal was a score of −3 to 0 on the Richmond Agitation and Sedation Scale (RASS).
Measurements |
The primary outcome was the percentage of time spent in the target sedation range without rescue sedation. Safety outcomes were based on adverse events. Blood samples were collected to measure formate concentration in plasma.
Main results |
The median dose was 4.33 (IQR, 3.08–4.94) mg/kg/h in the fospropofol group and 1.96 (IQR, 1.44–2.94) mg/kg/h in the propofol group. The median percentage of time spent in the target RASS range without rescue sedation was identical in both groups, with 83.33% (IQR, 74.43%–100.00%) in the fospropofol group and 83.33% (IQR, 77.45%–100.00%) in the propofol group (p = 0.887). At least one adverse event was identifed in 23 (76.7%) fospropofol patients and 27 (90.0%) propofol patients. The most common adverse events were tachycardia and hypotension. No paresthesia, catheter-related bloodstream infection or propofol infusion syndrome in both groups was reported. Three patients in the fospropofol group had mild hypertriglyceridemia, and nine patients in propofol group had hypertriglyceridemia (mild in eight patients and moderate in one patient) (10% versus 30%, p = 0.104). The formate concentration in plasma was very low, and no significant difference was identified at any time point between the two groups.
Conclusions |
Fospropofol disodium appears to be a feasible, effective and safe sedative for patients receiving invasive mechanical ventilation with long-term sedation.

• | Both fospropofol disodium and propofol can provide adequate sedation in ICU patients with mechanical ventilation. |
• | Fospropofol disodium had a comparable safety profile to that of propofol. |
• | The formate concentration in plasma was very low, and no significant difference was identified at any time point between the 2 groups. |
