RESUMO
PURPOSE: To report and discuss a case of fetal bradycardia in a parturient under anesthesia for cholecystectomy despite normal maternal oxygenation and arterial blood pressure. CLINICAL FEATURES: A 27-yr-old woman (gravida 2 para 1), with a fetus of 34 weeks gestation, received general anesthesia for cholecystectomy. After anesthesia induction and tracheal intubation, anesthesia was maintained with oxygen, sevoflurane and iv remifentanil infusion. While preparing for surgery, the fetal heart rate decreased within about half a minute to 70 beats x min(-1) and remained at that level. The maternal blood pressure, heart rate and oxygen saturation were normal. An emergency Cesarean delivery was performed. The infant had Apgar scores of 1 at one minute, 5 at five minutes, 7 at ten minutes and required resuscitation after birth. CONCLUSION: Ideally, women having non-obstetric surgery during the third trimester of pregnancy will have intraoperative fetal heart rate monitoring.
