About this study

The evaluation of the presented study will work on the practicability of inhalative sedation on the ICU, potential benefits and limitations of the ACD system in a postoperative sedated patient population in comparison to a standard intravenous sedation regimen with propofol, and focus on renal and hepatic function, cardioprotection and pharmacoeconomics

Read the detailed description

A goal-oriented sedation complies the ability to sedate the patient as deeply as necessary, and allow a modern ventilation regimen with early spontaneous breathing and a pain-free cooperative patient. The ideal sedative agent - with a short duration of action, predictable wake-up times, low drug toxicity, haemodynamic stability and less side effects, and a rational pharmacoeconomic impact nowadays - has still to be found. Inhalative anaesthetics show these properties, but until the introduction of AnaConDa© (Anesthetic Conserving Device, ACD) in 2005, the use of volatile anaesthetics on the intensive care unit (ICU) required specific evaporating devices or scavenging systems. The ACD, a modified heat- moisture filter, is connected to the breathing circuit of conventional ICU ventilators and a syringe pump delivers the volatile anaesthetic to the ACD where it is vaporized through a rod. Most of the exhaled gas is absorbed in a charcoal filter's membrane and reflected to the patient in the following inspiration. Randomised, controlled and comparative studies to the use of volatile anaesthetics in ICU via this innovative device are still missing. Isoflurane has been studied in small patient populations and in comparison to midazolam, while Sevoflurane - a newer volatile agent with short action, brief elimination time, and low hepatic biodegradation - has only been studied intraoperatively and in short-term sedation. This is the first prospective, randomised, clinical study on the feasibility of sevoflurane via the ACD for sedation in ICU patients until 72 hours in comparison to a standard intravenous sedation with propofol. The investigation will work on potential benefits and limitations of the use of volatile agents on the ICU, the quality of sedation (Richmond Agitation Sedation Scale, BIS), infusion rate stability of sevoflurane and respiratory parameters, short-term recovery (time from discontinuation of infusion until following verbal commands and extubation), haemodynamics, renal and hepatic function and adverse side effects.

  • PropofolDrug

    Also called disoprivan

    Propofol, 1.5-3 mg/kgBW/h, continuously via syringe pump, up to 72 hours

Questions about this trial

What is this clinical trial studying?

An observational study of Recovery From Sedation and Sevoflurane Consumption, run by Klinikum Ludwigshafen.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 13 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 4 Jan 2008. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Extubation time (time frame: Termination of sedation to extubation). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00586118, which also lists 3 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Jan 2008.
