Aberrant position of a central venous catheter: a cause for inadequate fluid replacement in septic shock
Abstract:
An unusual placement of a "central" venous catheter in the porto-hemiazygous system of a cirrhotic patient in septic shock is described. The catheter was misinterpreted as being located in a central vein and served initially as a guide for volume replacement. The high central venous pressure recorded (22 cm H2O) in spite of signs of hypovolemia led to the introduction of a Swan-Ganz catheter which confirmed the presence of hypovolemia. The proper position of the central venous catheter, especially in cirrhotic patients, should not only be confirmed by plain chest x-ray but also by injection of contrast medium.

Blood Pressure: Hypertension and Hypotension
Normal blood pressure is 120/80 mm Hg. Elevated blood pressure is 120-129/under 80 mm Hg. Hypertension, warranting treatment at 130/80 mm Hg, is often asymptomatic and can lead to severe cardiovascular events, aneurysms, peripheral arterial disease, chronic renal disease, or cardiac...
