Non-interventional Study Evaluating the Management of Pain Using a Technique Developed and Commonly Used by the Center, in Patients Who Underwent Arthroscopic Surgery of the Shoulder in the Outpatient Setting.

The surgery of the shoulder is usually performed under interscalene block (ISB), considered as a gold standard. This anesthesia is well suited for hospitalized patients but not for outpatients. Indeed, the ISB entails, in addition to a sensory block, a motor block often useless and important since it extends beyond the shoulder to the entire upper limb. It can also be a source of anxiety and cause the risk of compression in the limb operated because of the extended sensorimotor block. It is also responsible for a painful bounce almost constant with sometimes the very rapid installation of intense pain when the effect of the sensory block disappears. This pain can be difficult to relieve despite frequent use of opioids.

The Orthopedic and Traumatologic Surgery Department of the Clinique Chénieux has been operating patients requiring arthroscopic surgery of the shoulder according to the following technique. It involves the establishment of a short ISB (between 2h and 4h) relayed by a supra-scapular block (SSB) long (72h) through the placement of a perineural catheter thus allowing a continuous diffusion of Naropein® by an elastomeric pump. The same day or the day after the operation, the patients return to their home and are followed by nurses.

The objective of this technique is to better manage postoperative pain, thus allowing the management of patients in outpatient surgery. A prospective non-interventional study will make it possible, in a context of common practice, to obtain data on the management of pain in operated patients and then to consider a generalization of this practice to other centers.
