Summary
Severe hypoxemia can occur during cesarean sections due to physiological factors and anesthetic management. Careful monitoring with pulse oximetry is crucial for pregnant patients undergoing cesarean delivery.
Area of Science:
- Anesthesiology
- Obstetrics
Background:
- Pregnant patients are physiologically prone to hypoxemia.
- Short apneic periods during tracheal intubation can exacerbate hypoxemia in parturients.
Purpose of the Study:
- To report three cases of severe hypoxemia during cesarean sections.
- To identify potential contributing factors to hypoxemia in this population.
Main Methods:
- Case series describing three patients undergoing cesarean section with severe hypoxemia.
- Review of physiological factors and potential complications like drug effects and venous air embolism.
Main Results:
- Two patients experienced rapid hypoxemia after anesthesia induction, persisting throughout surgery.
- One patient developed sudden hypoxemia post-delivery, potentially due to venous air embolism.
Conclusions:
- Cesarean sections pose a risk for severe hypoxemia in parturients.
- Factors include physiological changes, anesthetic induction, ritodrine administration, and venous air embolism.
- Continuous pulse oximetry monitoring is recommended during cesarean sections.
