Question

eripheral venous wave- form analysis for detecting hemorrhage and iatrogenic volume overload in a porcine mode

Answer 1

Unrecognized hemorrhage and unguided resuscitation is associated with
increased perioperative morbidity and mortality. The authors investigated peripheral venous
waveform analysis (PIVA) as a method for quantitating hemorrhage as well as iatrogenic
fluid overload during resuscitation. Methods: The authors conducted a prospective study on
Yorkshire Pigs (n= 8) undergoing hemorrhage, autologous blood return, and administration
of balanced crystalloid solution beyond euvolemia. Intra-arterial blood pressure
