Clinical Trial Summary

Procedural sedation is an emergency medicine technique that provides a brief, deep sedation in order to perform very painful emergency emergent procedures such as displaced fracture or dislocated joints reduction. Propofol is recommended for this purpose, injected administered in slow IV bolus injections according to the technique known as manual titration. But despite this precaution, temporarily excessive sedation can happen, and a side effect can appear (arterial hypotension or respiratory depression). Target-controlled infusion (TCI) is an anesthesia technique that permits to obtain a precise constant and stable concentration of medication, boluses volumes of injection being calculated and delivered automatically by an electric syringe equipped with a software obedient to existing pharmacokinetic models. In the operating room, Ffor anesthetic induction, maintenance and awakening, respectively, in the operating room, the brain concentrations of propofol range respectively from 2 to 6 μg/mL, 2 to 4 μg/mL, and between 0.8 and 1.2 μg/mL, respectively. Since TCI has never been used in emergency departments (ED), the brain propofol concentrations which are necessary for sedation and awakening of the patient are not known and must be determined experimentally. In this single-center, prospective, interventional study, safety and feasibility of TCI will be studied in one ED with the primary objective of determining the brain propofol concentrations necessary to reach the an optimal sedation in for patients with indications of sustaining very painful orthopedic emergency emergent procedures


Description:

Procedural sedation is an emergency medicine technique that provides a brief, deep sedation in order to perform very painful emergency emergent procedures such as displaced fracture or dislocated joints reduction. For this purpose, propofol is a remarkable sedative agent for its very short elimination half-life, antiemetic property and myorelaxant effects. It is recommended to inject administer it in slow IV boluses injections according to the technique known as manual titration, but despite this precaution, temporarily excessive sedation can happen, and a side effect appear (arterial hypotension or respiratory depression). Target-controlled infusion (TCI) is an anesthesia technique that permits to obtain a precise constant and stable concentration of medication, boluses volumes of injection being calculated and delivered automatically by an electric syringe equipped with a software obedient to existing pharmacokinetic models. The age, size and weight of the patient are filledentered, then the syringe delivers the volume which is necessary and sufficient to reach and maintain the target concentration chosen by the practitioner. For anesthetic induction in the operating room, the brain concentrations of propofol used range from 2 to 6 μg/mL, then the general anesthesia maintenance is obtained with 2 to 4 μg/mL, and the patient awakening usually happens between 0.8 and 1.2 μg/mL. Since TCI has never been used in emergency departments (ED), the brain propofol concentrations which are necessary for sedation and awakening of the patient are not known and must be determined experimentally. In this single-center, prospective, interventional study, safety and feasibility of TCI will be studied in an ED with the primary objective of determining the brain propofol concentrations necessary to reach the an optimal sedation in for patients with indications ofsustaining very painful orthopedic emergency emergent procedures. As secondary objectives, we will study the characteristics of sedations obtained (level, delays, lengths); the Delays, lengths and levels of sedation obtained, overall delivered doses of propofol administered; the , nature, appearance delays and lengths of potential adverse events (AE) related to procedural sedation, particularly complications related to procedural sedation, and necessary interventions necessary to handle these AE., will be studied as secondary objectives

Outcome

Type Measure Description Time frame Safety issue
Primary Propofol brain concentration Propofol brain concentration necessary for the patient to reach a Ramsay score of 5 (optimal sedation) (Ce_Ramsay5) Between the beginning of sedation (T0) and the beginning of the orthopedic procedure (T_Ramsay5)
Secondary Delay between the beginning of sedation (T0) and the beginning of the orthopedic procedure (T_Ramsay5) the delay is the outcome, T_Ramsay5 (up to an anticipated average maximal time of 15 minutes after T0)] the delay is the outcome, T_Ramsay5 (up to an anticipated average maximal time of 15 minutes after T0)]
Secondary Propofol brain concentration when the patient spontaneously reopen his eyes (Ce_OuvertureYeux) Propofol brain concentration when the patient spontaneously reopen his eyes after the orthopedic procedure has been realized, the TCI syringe been switched off, and the immobilization been placed (Ce_OuvertureYeux) Time after T0 when the patient spontaneously reopen his eyes (up to an anticipated average maximal time of 30 minutes after T0)
