The Effect of Dexmedetomidine on Oxygen During One Lung Ventilation in Pediatric Surgery.

Summary

The children who will undergo OLV (one lung ventilation) through general anesthesia will be divided into two groups: The first will be intravenous infusion of dexmedetomidine at 0.4 mcg / kg / hour, and the second will be intravenous infusion of normal saline. We will take three samples of arterial blood gas (ABG) during the surgery at certain times. We record the hemodynamic values, PaO2, and calculate the value of the shunt Qs / Qt.
