消化系疾病患者检验性失血量调查218例

Blood loss from tests in patients with gastrointestinal diseases:An analysis of 218 cases

目的:调查消化系疾病患者的检验性失血量,从临床检验学的角度分析失血原因,寻找对策.方法:从医院LIS系统调取患者资料,回顾性调查2011-01/09住院消化系疾病患者218例的检验性失血量,统计住院日、总失血量、日均失血量、各检验项目的失血比例、血气分析的平均采血量等数据.结果:消化系疾病患者平均日失血量为7.63mL,血培养组日均失血量为8.57mL,非血培养组为5.58mL,两者差异显著,有统计学意义(P<0.01).结论:应重视有血培养检验患者的检验性失血问题,完善LIS系统功能、正确规范操作、合理使用普通注射器采血等措施有助于减少检验性失血.

AIM：To investigate the reasons for blood loss from tests in patients with gastrointestinal diseases and to explore countermeasures against such condition.METHODS：Data were obtained from hospital LIS,including hospital stay,total blood loss,average daily blood loss,blood loss ratio between different tests,average volume collected for blood gas analysis.RESULTS：The average daily blood loss in our patients was 7.63 mL.The average daily blood loss was 8.57 mL in the blood culture group and 5.58 mL in the non-blood culture group,with a significant difference between the two groups.CONCLUSION：Attention should be paid to blood loss in patients undergoing a blood culture test.Improvement of the functions of LIS,standard operation,and reasonable use of ordinary syringe for blood collection could help reduce blood loss from tests.
