  Description
Chinese Patients Requiring Surgery With Anesthesia 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 administered per the local Prescribing Information and endotracheal intubation or laryngeal mask airway (LMA). Note, 3 patients were excluded from all analyses who did not meet ASA Physical Status Class 1 through 3.

The agreement is:
unchecked The only disclosure restriction on the PI is that the sponsor can review results communications prior to public release and can embargo communications regarding trial results for a period that is less than or equal to 60 days. The sponsor cannot require changes to the communication and cannot extend the embargo.
unchecked The only disclosure restriction on the PI is that the sponsor can review results communications prior to public release and can embargo communications regarding trial results for a period that is more than 60 days but less than or equal to 180 days. The sponsor cannot require changes to the communication and cannot extend the embargo.


Limitations and Caveats
Limitations of the study, such as early termination leading to small numbers of participants analyzed and technical problems with measurement leading to unreliable or uninterpretable data
Types of surgery not restricted/stratified in the study and no standard practice in China on inhalation and intravenous anesthesia methods may skew/bias results. Gaps in study design and multiple outcome parameters make drawing conclusions difficult.
