Central stenosis

– Discussion:     – central stenosis produces compression of the thecal sac in contrast to lateral stenosis which involves compression of individual            nerve roots;     – may be congenital (idiopathic or developmental in achondroplastic dwarfs) or acquired;     – acquired stenosis:            – due to degenerative hypertrophic facets … Read more

Central Venous Pressure

– Discussion:  – rapid fluid infusion should be slowed when right atrial or central venous pressure reaches 12 to 15 mm Hg.  – in most patients, when atrial pressures are approximately 15 mm Hg, further increases do not seem to increase Cardiac Output;  – thus, when central venous or right atrial pressure is less than … Read more
