Effect of Maternal and Neonatal Oxygenation

July 1, 2013 updated by: Mahidol University

Effects of Neonate and Maternal Oxygenation in Low-dose Oxygen Supplement by Oxygen Cannula or Non- Supplement in Elective Cesarean Section: a Randomized Controlled Trial

Intraoperative supplemental oxygen has been given for most parturients undergoing cesarean section under spinal anesthesia. However, evidences supporting the practice is not clear nowadays, especially for healthy parturients who are monitored continuously with pulse oximeter. Furthermore, hyperoxia may produce free radicles which could harm fetus and newborns.

Changing practice is not that easy. This study has been conducted to prove that supplemental oxygen is not necessary for healthy parturients during cesarean section.

Detailed Description

Supplemental oxygen has been routinely given to parturients because doctors were concerned about desaturation. However, the evidences for giving oxygen was not strong, and the condition nowadays can be detected immediately with pulse oximeter which is a standard monitoring.

After this study finished, we will set a safety guideline for supplemental oxygen for healthy parturients undergoing elective cesarean section.
