[Anesthesia for brain tumor surgery during pregnancy: presentation of a case]

We report the case of a 26th-week pregnant woman undergoing craniotomy for excision of brain tumor. Main considerations for anesthetic management of pregnant women undergoing surgical operations are the following: Each pregnant women patient should be considered as "full stomach" regardless fasting period. All measures should be taken to ensure fetal oxigenation by maintaining an optimal placental blood flow. There is no evidence of teratogenesis of anesthesic agents except for nitrous oxide which should be avoided during first and second trimesters. Fetal monitoring should be instituted from week 16 on as well as uterine dynamics periods whenever possible because of the greater frequency of premature labor or abortion. In Neurosurgery, an exhaustive control of blood pressure and PaCO2 of the mother should be carried out and osmotic diuretic agents should be cautiously administered.
