Preoperative hypoxemia in conscious patients after subarachnoid hemorrhage.

摘要: We retrospectively examined partial arterial pressure of oxygen (Pao2) afer subarachnoid hemorrhage (SAH), adjusted for patient-related risk factors hypoxemia in 51 adult patients with no disturbance consciousness undergoing surgery clipping intracranial aneurysms. A control group 174 other operations were used comparison. Arterial blood gas analysis was performed while spontaneously breathing room air the supine position before induction anesthesia. The Pao2 SAH significantly lower (p<0.0001) than that after adjustment age, obesity, and smoking status. In three group, less 60 mmHg. Close monitoring oxygenation pulse oximetry is desirable, supplemental should be considered during transfer from patients' to operating suite, even conscious without cardiopulmonary disease.
