Me. Lovell et Jh. Evans, A COMPARISON OF THE SPINAL BOARD AND THE VACUUM STRETCHER, SPINAL STABILITY AND INTERFACE PRESSURE, Injury, 25(3), 1994, pp. 179-180
The interface pressures were measured between the sacrum, mid-lumbar s
pine and various support surfaces. Thirty healthy male volunteers were
recruited. ne spinal board, padded spinal board and vacuum stretcher
were the support surfaces evaluated. We found high and potentially isc
haemic pressures between the sacrum and the spinal board interface (me
an 147.3 mmHg). This was reduced in the padded board (115.5 mmHg) but
dramatically reduced with the vacuum stretcher (36.7 mmHg). It was als
o noted that no support was given to the normal lumbar lordosis by the
spinal board (padded and unpadded), but support was given by the vacu
um stretcher. This raises the question of how stable is an unstable sp
inal injury on a flat supporting surface.
