一次性采血针在糖尿病患者采血中的临床应用

目的观察采用一次性采血针给糖尿病患者采集动脉血兼做静脉血标本的应用效果。方法将符合标准的240例糖尿病患者分为两组,观察组与对照组各120例。观察组采用一次性采血针直接行动脉穿刺,采血成功后把采血针的刺塞端依次刺入需要采集静脉血液标本的各个真空采血管中,直至最后剩下血气分析时,拧下刺塞端的同时反折头皮针,迅速与经肝素润滑后的2mL注射器的乳头衔接,用注射器抽吸所需血量,采集完毕后立即送检。对照组先用一次性采血针配合真空采血管采集静脉血标本,再用经肝素润滑后的一次性5mL注射器采集动脉血,二者采集完毕后立即送检。分别比较两组的穿刺次数、采血时间、疼痛程度、皮下血肿及皮肤淤斑例数、标本合格率。结果观察组穿刺次数、采血时间、疼痛程度及皮下血肿例数差异有统计学意义（P〈0.05）;观察组皮肤淤斑例数明显低于对照组,差异有统计学意义（P〈0.01）;两组标本合格率差异无统计学意义（P＞0.05）。结论采用一次性采血针采动脉血兼做静脉血标本的方法,既可提高工作效率,又可减少患者的痛苦和采血的并发症,是一种理想的采血方法。

Clinical application of disposable blood sampling needle in diabetic patients

Objective To investigate the effect of disposable blood sampling needle for collection artery and venous blood samples in patients with diabetes.Methods A total of 240patients were divided into observation group and control group,with 120cases for each group.In observation group,disposable puncture needle was used to perform arteriopuncture,then the piercing plug of blood sampling needle was stabbed into vacuum venous blood collection tubes,and until only blood gas analysis was remained,the plug end of the spine was unscrewed and the scalp needle was reflexed,and rapidly linked up with the papilla of 2mL syringe that lubricated with heparin to collect artery blood sample for blood gas analysis.In control group,disposable blood sampling needle was used to collect venous blood samples into vacuum tubes,then the arterial blood was collected into 5mL disposable syringe that lubricated with 2mL heparin.Number of puncture,sampling time,the degree of pain,subcutaneous hematoma and ecchymosis cases,and the rate of qualified sample were compared between the two groups separately.Results The number of puncture,blood sampling time,the degree of pain and subcutaneous hematoma cases of the observation group were lower than control group（P〈0.05）.The skin ecchymosis cases of observation group observation was significantly lower than control group（P〈0.01）.The rate of qualified sample of the two groups was not statistically different（P〉0.05）.Conclusion Application of disposable blood sampling needle to collect arterial and venous blood samples could be an ideal method for collecting blood samples,which could improve the work efficiency,and reduce the pain of patients and complications related with blood collecting.
