Abstract

Arterial blood samples were taken from adult healthy patients before and 24 hours after bilateral nasal packing. The blood samples were investigated for PO2, PCO2, HCO3, pH and Hb. It was found that there is (i) an increase of high significance of PCO2 and HCO3-, (ii)) a significant increase of percentage of Hb., (iii) a highly significant decrease of PO2 in patients after nasal packing; (iv) as regards the pH, no significant difference was found. What we suggest is that bilateral anterior nasal pack results in hypoxia and hypercapnia due to hypoventilation.

摘要

对成年健康患者在双侧鼻腔填塞术前及术后24小时采集动脉血样本。对血样进行了氧分压（PO2）、二氧化碳分压（PCO2）、碳酸氢根（HCO3）、酸碱度（pH）和血红蛋白（Hb）检测。结果发现，（i）鼻腔填塞术后患者的PCO2和HCO3-显著升高，（ii）Hb百分比显著升高，（iii）PO2显著降低；（iv）关于pH，未发现显著差异。我们认为双侧前鼻孔填塞由于通气不足导致缺氧和高碳酸血症。
