Failure of Respiratory Function Clinical Trial
Official title:
Evaluation of Pupillary Distension Reflexes, as a Tool for the Monitoring of Analgesia for Patients in Intensive Care.
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.
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. ;
