NCT01068821

Brief Summary

The purpose of this study is to compare two cushioning materials (a gel mattress and an egg-crate foam mattress) placed beneath patients undergoing gynecologic surgery to prevent patients from sliding toward the head of the bed during head-down positioning. Our hypothesis is that the two materials will be equally good at preventing slide on the table and that slide will be less than 5 cm (\<2 inches) on average.

Outcome Measures

Primary Outcomes (1)

  • Amount of Patient Movement on the Operating Room Table

    Patients undergoing gynecologic surgery require steep (30 to 45 degree) Trendelenberg's position to allow adequate exposure of the pelvis. This position leads to a small amount of movement toward the head of the bed. The table was marked at the point of the anterior superior iliac spine (ASIS) and at the point where a vertical marker touching the acromioclavicular (AC) joint of the left shoulder drops to the table. At the end of the surgery, when the operating table is leveled, the final positions of ASIS and AC will be measured. Measurements were made in centimeters to the tenth position.

    About 150 minutes after start of surgery

Secondary Outcomes (1)

  • Number of Participants Reporting a Neurologic Deficit in Extremities After Surgery

    postoperative day 1 and postoperative week 3-8

Study Arms (2)

Egg crate foam mattress

ACTIVE COMPARATOR

Patients will be placed on egg-crate foam mattress instead of a gel pad by randomization. All other positioning and measurements, including outcomes measures will be the same as for the the primary experimental intervention (gel pad).

Other: Egg crate foam mattress

Interventions

Gel padOTHER

A gel pad (mattress) (approximately 3cm thick) is placed under the patient on top of the usual operating room mattress, directly in contact with patient's skin from buttocks to shoulders with the patient in dorsal lithotomy position under general anesthesia. Time in Trendelenburg's position and time operating are both recorded. The position of two bony landmarks (left anterior superior iliac spine and left acromioclavicular joint) are marked before Trendelenburg's position (30 to 45 degrees below horizontal) and immediately after returning the patient to horizontal position.
