Survey on ICP, target CPP and MAP measurement level in patients with severe acute brain injury in different ICUs

Abstract

Introduction Since most patients with acute brain injury are treated head-up at 30 to 45°, there can be a height difference of up to 15 cm between the heart and the ear canal. [ Table Omitted - see PDF ] Table 1 ICP threshold (mmHg); n(%) >15; 2 (6.7%) >18; 1 (3.3%) >20; 24 (80%) >25; 3 (10%) Minimal CPP (mmHg); n (%) >50; 6 (20%) >55; 4 (13.3%) >60; 16 (53.3%) >65 to 70; 4 (13.3%) Maximal CPP (mmHg); n (%) <70 to 75; 8 (26.7%) <80; 8 (26.7%) <85; 2 (6.7%) No limit; 12 (40%) Conclusion Considering the influence of position on CPP, the variations among centers and the narrow range of CPP thresholds, future studies and guidelines should describe where MAP is measured.
