Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: Show that the preoperative realization of a parasternal block reduces the posology of remifentanil administered during sternotomies;Secondary Objective: Evaluate the effect of parasternal block on : 1. Hemodynamic response 2. Dose of hypnotic (propofol) and analgesic (remifentanil) drugs during surgery 3. Inflammatory response 4. Pain level during extubation 5. Complications;Primary end point(s): Maximal dose of remifentanil required to maintain hemodynamic parameters (arterial blood pressure and heart rate) in the appropriate values during intubation, skin incision, sternotomy and sternal retractor setup;Timepoint(s) of evaluation of this end point: Intraoperative period : from intubation to sternal retractor setup | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): 1. Measure of hemodynamic parameters (arterial blood pressure and heart rate) and patient state index (PSi) 2. Dose of propofol and remifentanil administered during surgery 3. Serum concentrations of cytokines 4. Numeric scale of pain, ranging from 0 to 10 (0 = no pain, 10= worst possible pain), during extubation 5. Complication rate : - Complications related to parasternal block (wrong distribution of the local anesthetic, infection at injection site, rhythm disorders caused by intravascular injection of the local anesthetic) - Post-operative complications (acute respiratory distress syndrome, pneumopathy, kidney failure, hypertension);Timepoint(s) of evaluation of this end point: 1. Intraoperative period : from the start of general anesthesia maintenance, i.e. PSi within the 25-50 range, to the fifth minute after sternal retractor setup (refers to criteria 1) 2. Intraoperative period : from induction of anesthesia to skin closure (refers to criteria 2) 3. At induction of anesthesia, at the arrival in intensive care, at day 1, day 2, day 3, day 5 and day 7 at the time of the morning blood collection (refers to criteria 3) 4. During extubation (refers to criteria 4) 5. 7 days after surgery (refers to criteria 5) | — |
