An interventional study of Remifentanil and Sufentanil in Rapid Sequence Induction, sponsored by Centre Hospitalier Sud Francilien. Terminated at 1 site in France. Open to participants aged 55 Years and older. Per ClinicalTrials.gov, last updated 2026-05-26.
Sponsored by Centre Hospitalier Sud Francilien · Not applicable, Interventional, and Other
The patient is seen upstream by an anaesthetists resuscitator (MAR) in order to carry out his anesthesia consultation. If the patient meets the eligibility criteria he will be informed of the study and his signed consent will be obtained.
Patients will be divided into 3 parallel groups :
Constants are taken at T0. A non-invasive continuous monitoring (Clearsight ©) will be used to collect data: blood pressure, heart rate, cardiac output.
To ensure double-blinding the nurse who prepares the syringes is not part of the anesthesia team. He/she numbers them in syringe n°1 and n°2 to indicate the order of injection to the MAR.
The MAR injects the drugs according to the standardized study plan (see below):
The laryngoscopy is performed by an experienced MAR or nurse (IADE). The end of the intubation is defined by the fixation of the intubation tube (T3). Hemodynamic parameters are measured every minute for ten minutes after intubation (T4 to T13).
Maintenance of anesthesia is standardized with halogen gas (SEVOFLURANE) and an opioid (SUFENTANIL). Ten minutes after the patient's intubation (T13), the blind is lifted, allowing the addition of sufentanil in groups A and C before any surgical procedure.
Centre Hospitalier Sud Francilien is the lead sponsor of 57 studies on the registry; 13 are open to participants now.
