Prone Fluid Responsiveness in Children

Study on the Prediction of Fluid Responsiveness in Pediatric Patients Undergoing General Anesthesia With Prone Position

In pediatric patients in the prone position, the reliability of pulse pressure variation and stroke volume variation, and pleth variability index to predict fluid responsiveness have not previously been established. Perioperatively, in this setting, optimizing fluid management can be challenging, and fluid overload is associated with both intraoperative and postoperative complications. The investigator designed this study to assess the sensitivity and specificity of baseline PPV, SVV, and PVI the tidal volume (VT) challenge (VTC) and in predicting fluid responsiveness during elective neurosurgery.

Inclusion Criteria:

• elective neurosurgery and requiring prone positioning

Exclusion Criteria:

• (1) chronic cardiac arrhythmia; (2) depressed left (<30% of ejection fraction) (3) patients with pulmonary disease
