Causes and Prevention of Failure in Varicose Vein Operations

One hundred and one patients with poor results from the operative treatment of varicose veins were studied in an effort to determine the cause of the surgical failure. In a large majority, reoperation revealed that the primary cause of the poor result was the improper performance of the original operation. A smaller number of failures were due to errors in selecting the operative procedure. Relatively few poor results in long-term follow-up were attributable to the congenital predisposition to varicosity. When operation is properly planned and executed, it produces better long-term results than the injection compression therapy of varicose veins.     

股动脉及股静脉血气在烧伤脓毒症患者早期诊断价值

目的:探索股动脉及股静脉血气对烧伤脓毒症患者早期诊断价值。方法:选择自2009年7月至2014年12月我院收治的特重烧伤患者80例,根据是否患有脓毒症,将35例脓毒症患者作为观察组,45例非脓毒症患者作为对照组。在所有患者左侧股动脉、股静脉置管,并抽血,进行血气分析。结果:动脉血气分析中观察组患者股动脉血中HCO3-水平明显低于对照组,且差异具有统计学意义(P0.05);静脉血气分析中观察组患者股静脉血中Pv CO2显著高于对照组,Pv O2、Sv O2、HCO3-水平明显低于对照组,且差异均具有统计学意义(P0.05)。观察组患者的△PO2、△PCO2、△SO2、△HCO3-、△p H水平均显著高于对照组,且差异均具有统计学差异(P0.05)。结论:股动脉和股静脉血气分析可反映出机体组织的血流灌注情况及氧的供需状态,对烧伤脓毒症患者早期诊断具有重要价值。
