    A Retrospective Chart Review on Oxygen Saturation During Shoulder Arthroscopies in Lateral Decubitus and Beach Chair Positions
    (2013-06-11) Schmitt, Kayla; Kondratek, Melodie
    Purpose: This review provides a comprehensive comparison between the lateral decubitus and beach chair positions utilized while performing a shoulder arthroscopy. The intention is to determine whether one position is more advantageous over the other while comparing set-­‐up, cost, orientation, visualization, effectiveness of anesthesia and risk. Methods: A retrospective review was performed of 32 de-­‐identified charts, 16 from each operative position: lateral decubitus and beach chair. The 16 for each position contain exactly 50% male and 50% female patients, with ages ranging from 19 to 85. Data gathered includes oxygen saturation and oxygen administered at 15-­‐minute intervals throughout surgery, as well as de-­‐identified patient health history. Results: Lateral decubitus patients recorded a higher initial peripheral oxygen saturation percentage at 0 minutes than beach chair patients (96.2% beach chair, 97.8% lateral decubitus). However, beach chair patients recorded a higher peripheral oxygen saturation percentage at 45 minutes, near the end of surgery, than lateral decubitus patients (97.9% beach chair, 97.3% lateral decubitus). Lateral decubitus patients required less oxygen to be administered to maintain healthy peripheral oxygen saturation levels throughout the entire surgery on average (2.2 L/min lateral decubitus, 2.7 L/min beach chair). Conclusions: This study refuted the hypothesis that the peripheral oxygen saturation in beach chair-­‐positioned patients is higher than in the lateral decubitus position. Broad analysis of literature supports that most surgeons prefer the same operative position throughout all of their arthroscopic shoulder procedures, regardless of the circumstances.
