About

The aim of this study is to observe or not a reduction in the consumption of morphine within 72 hours of the realization of an erector spinae plane block when preparing for a non-instrumented spine surgery.

Full description

Posterior lumbar spine surgery is surgery described by patients as painful. While fusion surgery seems more painful than simple release surgery, release surgery remains a painful surgery for patients. The management of post-operative pain is therefore a priority for anesthesiological-surgical teams.

Multimodal analgesia, already recognized for other surgeries, is one of the keys to success, combining oral analgesics and regional local anesthetics.

The recourse to the realization of a block of the erector muscles of the spine was described for the first time in 2016, it is described there in the literature as not presenting any particular risk, simple to apply and having a satisfactory analgesia action. However, this process is little described in the context of spine surgery and even less in the context of randomized controlled trials.

The investigator therefore hypothesize that the realization of a block of the erector muscles of the spine, because of its satisfactory analgesia action mentioned above, will decrease the consumption of postoperative morphine and at the same time reduce the side effects due to the latter.

On the other hand, no study has evaluated the effectiveness of spinal block as part of an Enhanced Rehabilitation After Surgery (RAAC) program. Indeed, the effectiveness of this practice has already been proven in a context of conventional care, but to date no studies have been carried out in the context of care involving the original elements of the RAAC, such as rapid mobilization and multimodal oral analgesia, which could impact the effectiveness of the erector muscle blocks of the spine.

At the Clinique Saint Jean Sud de France, the management of spine surgeries is part of this Improved Rehabilitation After Surgery (RAAC) process, which is why it seemed relevant to the investigator to carry out a randomized, controlled study. , double-blind to assess the consumption of postoperative morphine during the 72 hours following a lumbar arthrodesis in this context of care.

Masking: Triple Blind

---

100 participants in 2 patient groups, including a placebo group

Block

Experimental group

Description:

The "Block" group will be made up of patients who will benefit from an injection of levopubivacaïne for the realization of the erector spinae plane block.

Placebo Comparator group

Description:

The "Placebo" group corresponds to the reference group, that is to say that it will consist of patients who benefit from an injection of physiological serum for the realization of the erector spinae plane block.
