With the development of science and technology, more and more hemodynamic monitoring techniques have emerged, from invasive and minimally invasive to noninvasive monitoring. Each technology has its own advantages and limitations, for burn patients, skin loss and form crust, so that is difficult to carry out many invasive, noninvasive operation. Compared to other hemodynamic monitoring technology, pulse indicated continuous cardiac output(PiCCO) is more accurate, safe, timely, effective, minimally invasive, better than the traditional Swan-Ganz catheter. Compared with FloTrac/Vigileo, PiCCO is less clinically restricted, more suitable for most severe burn patients. Non invasive hemodynamic monitoring technology is limited to the presence of burn wounds, so it is not widely carried out now.
