title: Hemodynamic and electrolyte changes in patients undergoing neuroendoscopic procedures.
abstract: OBJECTIVE
  Intraoperative hemodynamic alterations and postoperative electrolyte disturbances related to endoscopic third ventriculostomy (E3V) have been reported. We aimed to evaluate prospectively those changes in patients undergoing neuroendoscopic procedures.
  
  
  METHODS
  This study was carried out in 24 patients who underwent neuroendoscopic intervention. Sevoflurane was used for the induction and maintenance of anesthesia. Heart rate (HR), mean arterial pressure (MAP), peripheral oxygen saturation, end-tidal CO2, and body temperature values were recorded according to the stages of the operation. Blood gas and blood chemistry analyses were performed before and after endoscopic procedure and were repeated on the third postoperative day.
  
  
  CONCLUSIONS
  There were no significant differences in intraoperative HR and MAP. Bradycardia occurred only in 1 of the 24 patients during the dilatation. In conclusion, we suggest the use of 0.9% NaCl for intravenous fluid replacement and a warm lactated ringer solution for ventricular irrigation during E3V to prevent intraoperative hemodynamic changes and postoperative electrolyte disturbances.
