[Assessment of the state of water sectors in neurosurgical profile patients in the pre-, intra- and postoperative periods].

The state of water sectors has been analyzed at the stages of preparation to and performing anesthesia as well as in the early postoperative period in neurosurgical patients in connection with planned surgical procedures (37 cases). The impedance method of control of the hydration degree before operation allowed to find out a risk group--hypohydrated patients. In most cases the detected disturbances of the water-electrolytic balance could not be diagnosed clinically. Despite a relative stability of traditionally analyzed indices of circulation during anesthesia, the reactions of central hemodynamics were more pronounced than could be considered undesirable. The analysis performed makes a foundation for optimization of infusion and cardiotropic therapy both during anesthesiological maintenance of neurosurgical procedures and at the postoperative period.
