RESUMO
OBJECTIVE: To evaluate the effects of epidural, spinal, and general anesthesia on pain after lower-limb amputation. DESIGN: Cross-sectional survey. SETTING: Postamputation clinic. PATIENTS: 150 patients who were evaluated one to 24 months after their lower-limb amputation. INTERVENTIONS: Patients received epidural, spinal, or general anesthesia for their amputation. MEASUREMENTS: Standardized questions were used to assess stump pain, phantom sensation, or phantom limb pain preoperatively and postoperatively. Pain intensity was assessed on a verbal rating scale of 0 to 10. After the interview, each patient's medical history and anesthetic record were assessed. RESULTS: Patients who had received epidural anesthesia and those who had received spinal anesthesia recalled significantly less pain in the week after their surgery (P < 0.05). After an average of 14 months, there was no difference in stump pain, phantom limb sensation, or phantom limb pain between patients who received epidural anesthesia, those who received spinal anesthesia, and those who received general anesthesia for their amputation. Phantom limb pain continued to be frequent and severe despite patients' use of opioid analgesics, amitriptyline, and gabapentin. CONCLUSIONS: Patients who received epidural anesthesia and those who received spinal anesthesia recalled better analgesia in the first week after their amputation than did patients who received general anesthesia. Anesthetic technique had no effect on stump pain, phantom limb sensation, or phantom limb pain at 14 months after lower-limb amputation.

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.
