Estimate the Behavior of Chinese Anesthesiologists Practicing General Anesthesia With Sevoflurane

Study Overview
=================
Brief Summary
-----------------
This registry is primarily aiming to demonstrate the correlation between good practices of anesthesiologists and patient related outcomes including decreased overall anesthesia cost. The investigators would also like to demonstrate how the training background, and experience in inhalational anesthesia of the anesthesiologist influence their daily practice. At the end of the registry, the investigators would be able to demonstrate the influence of different practice pattern on patient related outcomes between the sites at which anesthesiologists follow modern anesthesiology practice based on their training/experience background and at which anesthesiologists do not follow same type of practice due to lack of their inhalational anesthesia training/experience.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Chinese Patients Requiring Surgery with Anesthesia<br>Chinese patients 18 to 70 years of age, meeting the American Society of Anesthesiologists (ASA) Physical Status Class 1 (normal healthy), Class 2 (mild systemic disease), or Class 3 (severe systemic disease), who underwent surgery requiring general anesthesia (sevoflurane) administered per local Prescribing Information and endotracheal intubation or laryngeal mask airway (LMA). | |

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Anesthesiologist Satisfaction With the Anesthesia Recorded at the End of the Operation Using a Numeric Analog Scale (NAS) | Anesthesiologist satisfaction with the anesthesia administered to each patient during surgery was recorded at the end of the operation using a Numeric Analog Scale (NAS) from 0 (not satisfied at all) to 10 (completely satisfied) are summarized. | Within 24 hours | 
| Patient Satisfaction With the Anesthesia Recorded at the End of the Operation Using a Numeric Analog Scale (NAS) | Patient satisfaction with the anesthesia recorded at the end of the operation within 24 hours using a numeric analog scale (NAS) from 0 (not satisfied at all) to 10 (completely satisfied) are summarized. | Within 24 hours | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Time to Loss of Consciousness of Patients Administered Anesthesia | The time to loss of consciousness was measured from commencement of administration of anesthesia to the patient's loss of consciousness (no response to command). | Up to 10 minutes | 
| Time to Intubation of Patients | The time to intubation of the patients was measured from the commencement of administration of anesthesia to intubation of each patient. | Up to 10 minutes | 
| Time to Eye Opening of Patients | Time to eye opening of patients was measured by the time from cessation of anesthesia administration to opening of the patients' eyes. After cessation of anesthesia, the investigators lightly tapped on the patients forehead or shoulder and asked the patients to open their eyes. This process was repeated about every minute until the patients opened their eyes. | Every minute after cessation of anesthesia until the patient opened his/her eyes | 
| Time to Extubation of Patients | The time to extubation of patients was measured from cessation of anesthesia administration to tracheal extubation of the patient. | Every minute after cessation of anesthesia until the patient was extubated |
