Evaluation of the Effect of Para-sternal Block on Postoperative Respiratory Function After Cardiac Sternotomy Surgery (PARACARD)

Postoperative pain after cardiac surgery is associated with reduced postoperative respiratory function. There is an association between greater pain and more pronounced decreases in lung volumes postoperatively. With an incidence of 10% to 25% of cases, pulmonary complications are the second source of postoperative morbidity after cardiac complications; in 2-5% of cases, the dysfunction is severe and leads to significant consequences that can lead to death. It has been shown that postoperative pain after cardiac surgery is associated with a reduction in functional respiratory capacity. There is an association between greater pain and more pronounced decreases in lung volumes postoperatively. The main objective of this study will be to evaluate the impact of locoregional anesthesia by parasternal block analgesic on postoperative respiratory function at D1 postoperatively

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: interventional arm; the experimental arm will receive the parasternal block with injection of locoregional anesthesia	Drug: parasternal block; Echo-guided loco-regional anesthesia by bilateral parasternal block in immediate preoperative. The drug used is Ropivacaine 2mg/ml, 0.2%. Injection of 20ml per side, under ultrasound control, after general anaesthesia and before skin incision, and therefore before surgery
Active Comparator: control arm not requiring loco-regional anesthesia.; the control arm will receive a standard treatment, without locoregional anesthesia	Drug: Standard pain management; Standard pain management care involves a multimodal strategy that includes the use of intravenous analgesics. Morphine medications are the mainstay of pain management

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change in postoperative forced vital capacity (FVC)	The primary endpoint was the change (reduction) in postoperative forced vital capacity (FVC) between the preoperative measurement and at D1 postoperatively.; "Forced Vital Capacity measured by SPIROLAB spirometry (Appendix).; "Vital capacity is expressed as % of theoretical value.	1 day

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Variation of FCV between both groups	Respiratory functional investigations at day 2 is forced vital capacity (FVC)	at day 2
Variation of FCV between both groups	Respiratory functional investigations at 1 month is forced vital capacity (FVC)	at 1 month
Variation of FCV between both groups	Respiratory functional investigations at 3 months is forced vital capacity (FVC)	at 3 months
Variation of forced expiratory volume in 1 second (FEV1)	Respiratory functional investigations at day 2 are forced expiratory volume in 1 second (FEV1)	at day 2
