ge-related Influence of Propofol or Isoflurane on PaCO2 Varied with SjvO2 in Neurosurgical Patients |

| Abstract: | Objective: To investigate age-related influence of propofol or isoflurane on SjvO2 during hypercapnia and hypocapnia in neurosurgical patients. Methods: Anesthesia in propofol group was induced with propofol 2mg/kg, fentanyl 2μg/kg and atracurium 0.5mg/kg and maintained with propofol 6-10mg compared with paired patients with thiopental 5mg/kg for anesthesia induction and isoflurane (1.0-1.3MAC) for anesthesia maintenance. Arterial pressure through radial artery and SjvO2 through internal jugular catheterization were assessed. Measurements were made in normocapnia, hypocapnia and hypercapnia. Results: Hypocapnia resulted in a significant SjvO2 decrease in the ≥50 years old patients anesthetized with propofol compared with other patients, and SjvO2 obvious increased in the < 50 years old patients administered with propofol in contrast to other patients. Conclusion: Care should be taken during anesthesia with propofol associated with hypocarbia inneurosurgical patients great than 50 years old. |
