Surgical patients may have compromised mobility and sensory deficits attributed to the use of specific types of anaesthesia care that include general, regional, monitored anaesthesia care, and moderate sedation/analgesia. The administration of sedative medications results in levels of sedation that range from consciousness to unconsciousness (Odom & Watson, ,20051).

As a surgical patient advances on the sedation continuum toward the level of general anaesthesia, there are a loss of protective mechanisms that include decreased pain sensation, loss of mobility and consciousness. Positioning injuries may occur if there is a failure to implement risk reduction strategies to avoid direct pressure, friction, and/or shear forces to a dependent body part.

The understanding of pressure is essential for the prevention of a patient positioning injury during surgery. Pressure occurs when the skin is compressed between a bony prominence and a hard surface such as the procedure bed. When external pressure exceeds normal capillary pressure of 32mm Hg, the patient is placed at an increase risk for impaired tissue perfusion. (Walton-Geer, 20092; AORN, 20103). It is the effect of direct pressure exceeding capillary pressure of 32mm Hg that may cause restriction of adequate circulation, resulting in ischemia of the underlying tissue.

Pressure combined with friction and shear that occurs on body areas with bony prominences create an opportunity for tissue damage. It is this type of tissue damage that may progress to a pressure ulcer attributed to improper patient positioning during surgical procedures. An understanding and knowledge of common pressure sites allow perioperative team members to select appropriate positioning devices and apply positioning techniques that will limit exposure to capillary pressure greater than 32mm Hg on tissue where possible.

Devon™ foam positioners have been proven to reduce pressure distribution by 48% at levels above 32mm Hg (Independent study4)
