About this study
Sedation-analgesia is an important therapy for patients in resuscitation. It requires a surveillance, in order to avoid excessive or insufficient dosages of sedative or nonmorphinics, sources of side effects. Yet, means of surveillance are limited in resuscitation care : variations of blood pressure and heart rate are not very sensitive criterias. Clinical scales to measure the sedation and analgesia level were proposed for patients in resuscitation, including the Richmond (RASS) sedation scale and the behavioural pain scale (BPS). The study of pupillary dilatation's reflex (RDP) due to a nociceptive stimulation is a tool proposed for the monitoring of the analgesia peroperative for patients under general anaesthetic. Yet, there isn't any study that measured the analgesia threshold by pupillometry for patients in resuscitation receiving a sedation-analgesia.
The main goal of this study is to measure the minimum intensity of a painful stimulation (tetanus), leading to a 10% raise of RDP in a cohort of patients in resuscitation care receiving sedation-analgesia continuously.
Read the detailed description
Secondary goals will be to bring this measures back to the pain score BPS and the pupillary diameter measured during a painful care (tracheal aspiration), as well as morphinics dosage.

Questions about this trial
What is this clinical trial studying?
A study testing Measure the minimum intensity of a painful stimulation in people with Failure of Respiratory Function, run by University Hospital, Grenoble at 1 site in France.
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 3 inclusion and 8 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 26 Jul 2016. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.
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?
Measure of pupillary dilatation's reflex (RDP) (time frame: 13 seconds). 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 NCT02843893, which also lists 16 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 26 Jul 2016.
