ABSTRACT
Atrial natriuretic peptide (ANP) plays a part in the regulation of volume homeostasis and possibly, in the pathophysiology of water and electrolyte disorder. Patients with serious burn injuries risk huge body fluids losses, which are compensated for by perfusion. Blood volume and the renin and aldosterone system are also disturbed. This study measured plasma ANP and vasoactive intestinal polypeptide (VIP) in patients with >20% total burned surface area (TBSA), at admission and 24 h post-admission.Eleven patients (mean age 46.5 years, 8 males) with a mean TBSA of 34.5% were sampled. Standard treatment was given. Eleven closely age-matched volunteers were used as controls. A specific ELISA method suitable for the measurement of ANP and VIP was used.ANP was higher (p<0.0001), while VIP was lower (p=NS) in patients' samples compared to controls. While the level of VIP was higher at 24 h post-admission, mean ANP level remained about the same. The increased levels of plasma ANP may result from volaemic disturbances during resuscitation, low VIP levels, the increase in pulmonary resistance or post-burn stress.
