Abstract:
Objective:To study difference in arterial oxygen(PO 2) pressure between the carotid artery and the femoral artery and its relation with hypoxia of brain after head injury.Methods:Forty patients with acute head injury were divided into four groups according to the GCS(Ⅰ:6 patients for GCS 3-5score;Ⅱ:16 patients for GCS 6-8 score;Ⅲ:8 patients for GCS 9-12 score;Ⅳ:10 patients for GCS 13-15score).The PO 2 of the carotid artery and the femoral artery was monitored for every patient.At the same time,26 patients from all groups were monitored using transcranial dopplergraphy.Additional,22 patients with severe head injury were continuously monitored on PO 2 of the carotid artery and the femoral artery for 5 days.Results:(1)The difference in PO 2 between the carotid artery and the femoral artery was identified in Ⅰ and Ⅱ groups.The PO 2 of carotid artery is much less than that of femoral artery(P
