Pleth Variability Index Monitoring in Pediatric Craniosynostosis Surgery (PVI-CRANIO)
13 juin 2026 mis à jour par: Muzaffer GENCER
Association of Pleth Variability Index Monitoring With Intraoperative Hemodynamic Control in Pediatric Craniosynostosis Surgery
This prospective observational study aims to evaluate the role of pleth variability index (PVI) and perfusion index (PI) monitoring in intraoperative hemodynamic control among pediatric patients undergoing craniosynostosis surgery.
Patients aged 0-6 years will be monitored intraoperatively using standard anesthesia monitoring together with PVI and PI measurements.
Hemodynamic parameters, including systolic, diastolic and mean arterial pressure, heart rate, central venous pressure, oxygen saturation, body temperature, urine output, blood loss, fluid replacement, blood product requirement, serum lactate level, blood gas parameters and intraoperative complications will be recorded.
The study will assess the association between PVI/PI changes and intraoperative hemodynamic status, bleeding and transfusion requirements.

Description détaillée
Craniosynostosis surgery in pediatric patients is associated with a high risk of intraoperative blood loss and hemodynamic instability. Because children have a relatively low circulating blood volume, early detection of intravascular volume changes is essential for maintaining adequate perfusion and preventing hypotension. Goal-directed fluid management may improve oxygen delivery and overall hemodynamic stability during major surgical procedures.
Pleth variability index (PVI) is a noninvasive dynamic parameter derived from pulse oximetry waveform analysis and reflects respiratory variations in the perfusion index (PI). PI and PVI may provide useful information regarding peripheral perfusion, volume status and fluid responsiveness during mechanical ventilation. However, data regarding the utility of these parameters in pediatric craniosynostosis surgery are limited.
In this prospective observational study, pediatric patients aged 0-6 years undergoing craniosynostosis surgery will be followed intraoperatively. PVI and PI values will be recorded at predefined time points during surgery together with standard hemodynamic and perioperative parameters. Systolic, diastolic and mean arterial pressure, heart rate, central venous pressure, oxygen saturation, body temperature, urine output, estimated blood loss, amount of fluid replacement, blood product requirement, serum lactate level, blood gas parameters and intraoperative complications will be documented. The relationship between PVI/PI measurements and intraoperative hemodynamic changes, bleeding, fluid administration and transfusion requirements will be analyzed.
