Brief Summary:
The beach chair position (BCP) has been commonly used for shoulder arthroscopic surgery. Hemodynamic instability is frequently encountered problem associated with BCP. In addition, high rates of cerebral desaturation events have been reported during surgery in BCP. Although fluid loading could alleviate hypotension associated with BCP, it may lead to volume overload. As an alternative to static indices, dynamic preload indices such as pulse pressure variation (PPV) and stroke volume variation (SVV) were reported to be sensitive predictors of fluid responsivness in several surgical condition. The investigators will examine the abilities of PPV and SVV to predict fluid responsivness during shoulder arthroscopic surgery in BCP. Using transesophageal echocardiography (TEE), the investigators will directly estimate the change of cardiac output during BCP.

Study Type : Observational
Actual Enrollment : 42 participants
Observational Model: Case-Only
Time Perspective: Prospective
Study Start Date : November 2014
Actual Primary Completion Date : July 2015
Actual Study Completion Date : July 2015



Primary Outcome Measures :
  1. The changes between dynamic preload indices (SVV and PPV) and stroke volume index during beach chair position. We will measure them to evaluate the effect of beach chair position on PPV and SVV. [ Time Frame: The participants will be followed up to 5 minutes after fluid challenge. ]
    To investigate the ability of SVV adn PPV to predict fluid responsiveness during beach chair position, using ROC curve.
