  Purpose
This study is a 3-legged randomized study examining whether during shoulder surgery performed in the beach chair position active compressions of the lower leg with a sequential compression device (SCD) have a superior effect on stabilizing cerebral and circulatory hemodynamics when compared to TED stockings or a control group without any stockings.

Condition Intervention
Hypotension Device: Sequential compression device Other: TED stockings

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single (Care Provider)
Primary Purpose: Treatment
Official Title: Stabilizing Cerebral and Circulatory Hemodynamics During Shoulder Surgery in the Beach Chair Position Using Sequential Compression Device (SCD) or TED Stockings Compared to a Control Group

Primary Outcome Measures:
  • cerebral oxygenation [ Time Frame: per minute ]
    cerebral oxygenation averaged of 1 min during the operation


Secondary Outcome Measures:
  • ephedrine [ Time Frame: throughout duration of anaesthesia, approximately 60 minutes ]
    amount of ephedrine used during surgery

  • cardiac output [ Time Frame: per minute ]
    cardiac output averaged over 1 minute during the entire surgery

  • Stroke volume [ Time Frame: per minute ]
    stroke volume averaged over 1 minute during the entire surgery

  • mean arterial pressure [ Time Frame: per minute ]
    MAP averaged over 1 minute during the entire surgery


Estimated Enrollment: 60
Study Start Date: May 2011
Estimated Study Completion Date: November 2012
Estimated Primary Completion Date: November 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Sequential compression device
During arthroscopic shoulder surgery, an SCD device will be applied to the patients legs during surgery. Cerebral oxygenation and circulatory parameters will be recorded continuously throughout the surgery. Recordings will be hidden to the primary caregiver.
Device: Sequential compression device
a sequential compression device will be applied to the legs
Other Name: SCD express Kendall
Experimental: TED stockings
During arthroscopic shoulder surgery, TED stockings will be applied to the patients legs during surgery. Cerebral oxygenation and circulatory parameters will be recorded continuously throughout the surgery. Recordings will be hidden to the primary caregiver.
Other: TED stockings
TED stockings will be applied to the patients legs during surgery
Other Name: TED compression stockings, Kendall
No Intervention: Control
no stockings will be applied to the patients legs
