Overview
Brief Summary
The purpose of this randomized double-blind study is to compare the analgesic efficacy of the bilateral Erector Spinae Plane (ESP) block versus the bilateral Thoracic Paravertebral block (TPVB), by ultrasound-guided single injection in patients who underwent sternotomy for cardiac surgery.
Detailed Description
Cardiac surgery causes moderate to severe postoperative pain during the first 24 - 48 post-operative hours. This pain is greatly increased by mobilization (respiratory physiotherapy) and leads to the consumption of morphine. Appropriate analgesia, along with a reduction in morphine consumption are important factors in reducing morbidity after cardiac surgery and allow better postoperative rehabilitation. Recently, the concept of multimodal analgesia has become established, which corresponds to ensuring optimal analgesia through the use of non-morphine drugs associated with locoregional analgesia. During cardiac surgery, Paravertebral block (TPVB) technique is the first line of reference in our establishment. Lately, a new approach of blocking the intercostal nerves called Erector Spinae Plane block (ESP) has been discovered. It is a technique that seems simpler and safer than TPVB. Until now, the analgesic efficacy of the ESP block compared to TPVB after cardiac surgery by sternotomy has never been studied.

Outcomes
Primary Outcomes
Pain assessment
Time Frame: 6 hours from the end of the surgery
Pain assessment measured with Visual Analogue Scale (VAS) between 0 (no pain, best outcome) and 10 (worst possible pain, worst outcome) at mobility, (respiratory effort during peak flow meter measurement)
Secondary Outcomes
- Efficacy of the block (a)(During the surgery)
- Efficacy of the block (b)(During the surgery)
- Efficacy of the block (c)(During the surgery)
- Intraoperative sufentanil consumption(During the surgery)
- Postoperative pain assessment(3, 6, 12, 24, 48 hours from the end of the surgery)
- Postoperative Morphine consumption(3, 6, 12, 24, 48 hours from the end of the surgery)
- Side effects associated to morphine(3, 6, 12, 24, 48 hours from the end of the surgery)
- Complication(s) associated to the procedure(48 hours from the end of the surgery)
