Spine-Intra-Abdominal Pressure (SIAP) - Case Study

The SIAP study investigates the effect of using Ergotrics` Inflatable Prone Support (IPS) on intra-abdominal pressure (IAP) during spine surgery.

Study background
The objective of this study is to demonstrate the ability of the inflatable Prone Supports (IPS) to lower the IAP of patients in the prone position. Whenever the patients’ position is changed to prone, the IAP is increased due to abdominal compression.1,2 It has been demonstrated previously that an increased IAP is linked to increased bleeding. The ability to reduce IAP will be assessed by measuring IAP before and after inflation of the IPS. The METC (Medical Ethics Review Committee) has approved the SIAP study submitted by Dr. Van Eijs (anesthesiologist at ETZ, Tilburg, The Netherlands). The study will enroll 40 patients, aged between 18-70 and a body weight < 120 kg.
