动脉血PaCO_2对慢性缺血性脑血管病的意义

Significance of arterial blood PaCO_2 on chronic ischemic cerebrovascular disease

目的探讨PaCO2对于慢性缺血性脑血管病的意义。方法回顾武警总医院神经外科2015-01—2016-12慢性缺血性脑血管病患者80例及同时期不伴有脑血管病人51例,血气分析仪器均采用全自动血气分析仪,利用t检验对动脉血PaCO2进行对照分析。结果慢性缺血性脑血管病患者动脉血PaCO2较正常人水平高(P<0.05),同时此类患者术后PaCO2较术前明显降低(P<0.05)。结论动脉血PaCO2对于慢性缺血性脑血管病的诊断及疗效评估均有参考价值。

Objective To discuss the significance of partial pressure of carbon dioxide to patients With chronic ischemic ce-rebrovaseular disease. Methods We reviewed the patients with chronic ischemic cerebrovascular disease treated by surgical opera- tion （80 cases） and people without chronic isehemic cerebrovascular disease （51 cases） admitted in neurosurgery of Chinese Armed Police General Hospital from January to December in 2016. We collected the partial pressure of carbon dioxide of the subjects by fully automatic blood gas analyzer, then compared the difference of partial pressure of carbon dioxide between normal people and patients with chronic ischemic cerebrovascular disease. We analyzed the preoperative and postoperative partial pressure of carbon dioxide of these patients. Results The carbon dioxide levels of patients with chronic ischemic cerebrovascular disease were higher （P〈0.05） than normal persons,while the postoperative carbon dioxide levels were significantly decreased （P〈0.05）. Conclusion Partial pressure of carbon dioxide has reference value for the diagnosis and curative effect evaluation of chronic ischemic cerebro- vascular disease.
