SIAP (Spine Intra-Abdominal Pressure) Study

Oppe Project

Pressure Point Studie

Intra-Abdominal Pressure in Neurosurgery

The SIAP study examines the effect of using the Inflatable Prone Support (IPS) of Ergotrics on Intra-Abdominal Pressure (IAP) during spine surgery.

The aim of this study is to demonstrate that the Inflatable Prone Supports (IPS) are able to lower the IAP of patients in the prone position. When the patient’s position is changed to the prone position, the IAP is increased as a result of abdominal compression. It has previously been shown that increased IAP is linked to increased bleeding. The ability to reduce IAP is assessed by measuring IAP before and after inflation of the IPS.

To map the user feedback of the IBO, IPS and Hummingbird, Ergotrics, with the financial support of Flanders Innovation & Entrepreneurship, organised the OPPE study (Optimization of the Proning Procedure in Europe).

7 renowned hospitals in 5 countries have already participated in the study (Universitätsspital Zürich; Krankenhaus Wermelskrichen, Germany; Schön Klinink Vogtareuth, Germany; University Hospital Brussels, Belgium; Akademiska sjukhuset Uppsala, Sweden; Elisabeth-Tweesteden Hospital, Netherlands; MC Zuyderland Heerlen, The Netherlands) and 3 other hospitals have committed to participate in the study in 2020.

Pressure points on the skin increase the risk of pressure ulcers. This study will compare the pressure over the entire surface of the breast and pelvic skin when positioning on the IPS and other positioning systems.

All patients undergoing (long-term) surgery are at risk of developing pressure ulcers. Research has shown that it is important to keep pressure below 30mmHg to prevent pressure ulcers. It is generally accepted that air results in a better redistribution of pressure. Therefore, it is likely that redistribution of the pressure will reduce the associated risk. This study shows the pressure redistribution and identifies the areas of highest pressure using pressure mapping. Different positioning materials (Ergotrics’ Inflatable Prone Support (IPS), Steffee cushion, Wilson-Frame, traditional gel / foam filled cushions / bolsters / rolls) will be compared in terms of pressure distribution and areas of highest pressure.

According to the review published by Depauw et al. (2019), the incidence of complications in neurosurgery and neurological disorders may be due to increased IAP (intra-abdominal pressure), known as intra-abdominal hypertension (IAH) or abdominal compartment syndrome in critically ill patients, and its impact may be significant.

Prone Positioning: Is It Safe and Effective?

Dirkes, Dickinson, Havey and O’Brien (2012) emphasize the benefits of prone ventilation and positioning. However, this procedure also entails potential risks and complications, which can have consequences for both the patient and the healthcare provider. For example, lifting patients to prone position can cause back and other injuries to staff.
