OBJECTIVE: To evaluate the pressure placed on the shoulders as a function of varying degrees of head-down tilt (Trendelenburg) and to compare these pressures among three different patient-positioning systems. Study Design: Participants were placed in the dorsal-lithotomy position with arms tucked and tilted at 5, 10, 15, 20, 25, and 30° of head-down tilt. Using a manometer, we measured the pressure (cm H2O) on the shoulders at each angle for three support devices: the Skytron shoulder support (Grand Rapids, MI), the Allen shoulder support (Allen Medical System, Acton, MA), and the Allen Hug-u-Vac. RESULTS: Among 23 participants, body mass index (BMI) (mean ± standard deviation) was 24.5 ± 4.3 kg/m2. As the tilt angle increased, so did the shoulder pressure for all support systems. At 30° of Trendelenburg, the Allen Hug-u-Vac transmitted less pressure to the shoulders than the Skytron (right and left, p<0.001) and the Allen shoulder supports systems (right p<0.001, left p=0.434). When asked, "Which system was most comfortable?" 74% of the participants reported that they preferred the Hug-u-Vac (p<0.001). CONCLUSION: Shoulder pressure increases as tilt angle increases. Of the three support systems tested, the Allen Hug-u-Vac transmitted less pressure to the shoulders at 30° of Trendelenburg than the Skytron and the Allen shoulder support systems.
