Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: Evaluation by the sniff test of the effect of continous parietal analgesia with ropivacaine on diaphragmatic function after upper abdominal surgery;Secondary Objective: Evaluation of the effect of continous parietal analgesia with ropivacaine on : - IPmax and EPmax - Oxygen saturation - Post operative pulmonary complications (pneumonia, atelectasis, pleural effusions) - Morphin consommation - Post operative recovery ;Primary end point(s): Measure of diaphragmatic function with the sniff-test;Timepoint(s) of evaluation of this end point: V1 (inclusion), V2 (after surgery (H0) : H24, H48, H72, H96, H120, Day 6), V3 (day 7) and V4 (6 weeks) | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): - Measure of diaphragmatic function with maximal buccal inspiratory pression (IPmax) and maximal buccal expriratory pression (EPmax) - Oxygen saturation - Pulmonary complications : pneumonia, atlectasia, pleural effusions - Morphin consommation and associated complications (nausea, vomiting, somnolence) ;Timepoint(s) of evaluation of this end point: V1 (inclusion), V2 (after surgery (H0) : H6, H24, H48, H72, H96, H120, Day 6), V3 (day 7) and V4 (6 weeks) PEmax and PImax are not performed at V2 (H6) | — |
