Spinal Versus General Anesthesia for Ambulatory Anesthesia

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to describe, in real-life conditions, the factors influencing the choice of anesthesia (spinal anesthesia or short general anesthesia) in outpatient surgery.

Detailed Description
-----------------
This is a cross-sectional, observational, prospective, multicentre study, conduct in France among a representative sample of anesthesiologists. The factors influencing the choice of anesthesia (spinal anesthesia or short general anesthesia) will be assessed in patients undergoing an outpatient surgery. Data will be collected by the physician during the inclusion visit (peripostoperative consultation). Additional data regarding the patient's perception (pain and satisfaction) will be collected using a self-questionnaire 7 days after the surgery.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Factors influencing the choice of anesthesia (spinal anesthesia or short general anesthesia | All proposed factors will be described using a 4-levels verbal scale (decisive / important / of little importance / unimportant). The factors will be described from the questionnaire completed by the investigator during the inclusion visit, before the surgery. Decisive factors for the choice of anesthesia will be described and compared between the two subgroups.spinal anesthesia and short general anesthesia. | During the perioperative consultation (patients are included at the time of the perioperative consultation prior to their surgery): baseline visit | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Patients' characteristics in each subgroups | Patients' characteristics (demographic data, ASA physical status, risk factors...) will be described from the questionnaire completed by the investigator during the inclusion visit, before the surgery. | At the time of the perioperative consultation prior to their surgery (start of the inclusion visit or baseline visit) | 
| Postoperative period from waking up to eligibility for discharge from hospital according to the type of anesthesia | Will be described from the questionnaire completed by the investigator during the inclusion visit, after the surgery. | Up to 24h after the surgery | 
| Patients' satisfaction according to the type of anesthesia based on 2 questions using a 4-levels verbal scale | Will be described from the self-questionnaire completed by the patient 7 days after the surgery. | 7 days after surgery (i.e. 7 days after the inclusion) | 
| Patients' pain according to the type of anesthesia using a VAS scale | Will be described from the self-questionnaire completed by the patient 7 days after the surgery. | Up to 7 days after surgery | 
| Costs of spinal and general anesthesia | Will be described from the questionnaire completed by the investigator during the inclusion visit. | The day of the surgery | 
| Use and safety of Baritekal® (prilocaine) if applicable | Modalities of spinal anesthesia with prilocaine. Percentage and nature of adverse effect (serious or not) after intrathecal anaesthesia with prilocaine. | During surgery |
