Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The pneumoperitoneum during laparoscopic surgery in pediatrics has the potential to cause an increase of intracranial pressure (ICP). Previous studies have proposed that ultrasonographic measurements of the optic nerve sheath diameter (ONSD) correlate with signs of increased ICP. Therefore, this study aims to confirm the increased ICP by ultrasonographic measurement of ONSD during laparoscopic surgery in pediatric patients.

Intervention Type DEVICE

A thick layer of gel is applied on the upper closed eyelid. The linear 13- to 6-MHz ultrasound probe is then placed in the gel, without exerting pressure on the eye. Two measurements are taken for each optic nerve: one in the transverse plane, with the probe being horizontal, and one in the sagittal plane, with the probe being vertical. The final ONSD is the mean of these measurements.
