Methods: According to certain screening criteria, 100 outpatient patients in our hospital were included as the research objects, and the screening period ranged from March 2019 to March 2021. The patients were coded by computer and divided into two groups according to the requirement of 1:1 group to implement different nursing modes, namely the control group (routine nursing, n50) and the study group (comprehensive nursing, n50). The puncture success rate was taken as the observation index to analyze the application value of the two nursing modes, compare the quality of blood samples and nursing effect of the two groups, evaluate the nursing risk and summarize the application value of comprehensive nursing. Results: Compared with the puncture success rate of the two groups, the study group had a significant advantage, that is, the success rate was higher (P 0.05). Compared with the standard rate of blood samples in the two groups, the results showed that the study group had more advantages, that is, the standard rate was higher (P 0.05);Comparing the nursing effects of the two groups, the results showed that the study group had obvious advantages in nursing satisfaction and nursing risk incidence compared with the control group (P 0.05). Conclusions: For outpatient blood sampling patients, nursing interventions such as comprehensive nursing have important application value. This nursing model can improve the success rate of blood specimen treatment and puncture, promote nursing satisfaction and improve nursing safety, which is worthy of clinical thinking and reference.展开更多

Methods: 40 blood samples were selected in the completely random manner within the range from July 2019 to December 2020.Conduct statistics and analysis on the inspection of all specimens, clarify the causes of the unqualified specimen inspection, and formulate the solution measures according to the reasons. Results: of 40 blood specimens, 21 specimens failed the inspection, and the unqualified rate was 52.50%. Many reasons caused the unqualified blood specimens, mainly including timely failure, specimen coagulation and poor standardization of blood sampling. Conclusion: during the test of blood samples. Therefore, in order to improve the qualified rate of blood specimen inspection, it must fully clarify the causes of the unqualified inspection phenomenon, and take timely solution measures.展开更多
