The purpose of this study is to assess, in real life, the efficacy and the eligibility for discharge of a local anesthetic, CLOROTEKAL®, used for spinal anesthesia in short outpatient surgery.

This is a longitudinal, observational, prospective, multicentre, national study, conducted in France, from a representative sample of physician anesthetists.

The efficacy and safety in real life of CLOROTEKAL® will be assessed in patients undergoing a short outpatient surgery under spinal anesthesia. Data will be collected by the physician during two visits (pre-anesthesia and per-postoperative consultation). Additional data regarding the patient's perception (safety, pain and satisfaction) will be collected using a self-questionnaire.

Inclusion Criteria:

• Adult patients seen in pre-anesthesia consultation for ambulatory surgery
• Patients for whom a spinal anesthesia using CLOROTEKAL® is planned
• Patients accepting and able to complete a satisfaction self-administered questionnaire
• Informed patients who accept the computer processing of their medical data and their right of access and correction

Exclusion Criteria:

• Patients with contra-indications to spinal anesthesia (eg decompensated cardiac insufficiency, hypovolemic shock….)
• Patients with contra-indications to chloroprocaine (hypersensitivity to the active substance, medicinal products of the para-aminobenzoic acid ester group, other ester-type local anaesthetics or to any of the excipients ; Intravenous regional anaesthesia (the anesthetic agent is introduced into the limb and allowed to set in while tourniquets retain the agent within the desired area), serious problems with cardiac conduction, severe anemia)
• Patients participating or having participated in the previous month in a clinical trial in anesthesiology

Patients scheduled for surgery under spinal anesthesia of short duration will be informed about the study and will be asked to participate, from about day -14 (pre-anesthesia consultation) to 24h after the day of surgery.
