Cardiorespiratory responses to fluid administration in peritonitis

Abstract
Intravascular volume expansion was studied in 59 critically ill patients with a wide variety of sepsis and in a small group of 12 patients with peritonitis; either 500 ml of 5% albumin solution or 2 units of packed red blood cells were given over a 60-min period. During the 2-h period after volume loading, significant increases in mean arterial pressure (MAP), pulmonary capillary wedge pressure (WP), central venous pressure (CVP), and oxygen consumption (Vo2) were observed. One hour after fluid administration MAP had risen from 72 ±pM 16 (SD) at baseline to 78 ±pM 17 mm Hg (p
