title: Neonatal acid-base status following general anesthesia for emergency abdominal delivery with halothane or isoflurane.
abstract: OBJECTIVE
  To determine whether halothane or isoflurane as anesthesia for emergency abdominal delivery is associated with better fetal acid-base parameters.
  
  
  METHODS
  Randomized study.
  
  
  METHODS
  Inpatient Level III perinatal referral center in a university hospital.
  
  
  METHODS
  Sixty-six gravidas undergoing emergency abdominal delivery under general anesthesia for fetal distress.
  
  
  METHODS
  Randomization to receive halothane or isoflurane at 0.7 minimum alveolar concentration as part of a standard anesthetic technique.
  
  
  RESULTS
  Umbilical artery and vein blood gases were obtained and compared for hydrogen ion concentration, partial pressure of carbon dioxide, partial pressure of oxygen, and base deficit. There were no significant differences between the isoflurane and halothane groups.
  
  
  CONCLUSIONS
  There is no difference in the frequency or severity of acidosis associated with isoflurane or halothane when used for general anesthesia for emergency abdominal delivery of a distressed fetus.
