534例呼吸系统疾病患者艾伦试验结果分析

Allen's test in 534 patients with respiratory diseases

目的了解呼吸内科住院患者艾伦试验阳性率以及可能影响因素。方法2007年11月至2008年5月对在呼吸内科住院的患者,入院当天进行及住院后接受桡动脉穿刺采血7d后进行艾伦试验。结果534例进行了919次艾伦试验,其中3例单侧艾伦试验阳性,分别占534例的0.6%和919次艾伦试验的0.3%。结论呼吸系统疾病患者桡动脉穿刺前艾伦试验是有益的。

Objective This study was designed to evaluate Allen＇s test in patients with respiratory diseases. Methods The subjects with various respiratory diseases from December of 2007 to May of 2008 were recruited. A nurse performed the first Allen＇s test on patient＇s left and right hands prior to or without radial artery puncture. Another nurse repeated Allen＇s test if the test outcome was positive. Patients who had radial artery puncture would receive another Allen＇s test 7 days later. The inadequate collateral blood circulation of arm was diagnosed as positive Allen＇s test. Results Five hundred and thirty-four patients with a median age of 67 years received Allen＇s tests. Totally 534 patients were performed Allen＇s tests 919 times. Three patients without any radial artery puncture had positive Allen＇s tests,which accounted for 0.6% of 534 patients and 0.3% of 919 Allen＇s tests respectively. Conclusions The positive rate of Allen＇s test is very low in patients with respiratory diseases. It keeps uncertain that Allen＇s test should be used routinely prior to radial arterial puncture in patient with respiratory disease.
