Trendelenburg's Slide Prevention Study (SPS)
Randomized Controlled Trial Comparing Commonly Used Techniques to Prevent Slippage During Steep Trendelenburg's Position
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.

Intervention / Treatment |
---|---|
Active Comparator: Egg crate foam mattress
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).
|
An egg-crate foam mattress (approximately 5cm 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.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Amount of Patient Movement on the Operating Room Table
Time Frame: About 150 minutes after start of surgery
|
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.

Number of Participants Reporting a Neurologic Deficit in Extremities After Surgery
Time Frame: postoperative day 1 and postoperative week 3-8
|
The neurologic deficit was assessed as follows: Patients' postoperative care was unchanged from routine for this study.
Any postoperative complaints regarding limb pain or weakness or numbness were recorded and assessed with neurologic exam to determine sensation or motor components.
Absence of resolution was documented.
