ABSTRACT
【Objective】 To investigate the resource allocation status of blood testing laboratories in 14 blood stations in Gansu Province, explore the impact of differences in basic conditions on the comprehensive testing ability of laboratories, so as to promote the homogenization and standardization of blood screening capacity in blood stations in Gansu and improve blood safety and effectivenes. 【Methods】 An evaluation index system of laboratory resource allocation was constructed and a question-naire was designed. The data of human resources, infrastructure and key equipment of 14 blood stations were collected. The entropy weight -TOPSIS method was used to evaluate and rank the resource allocation of 14 blood stations. 【Results】 In the comprehensive evaluation of blood testing laboratory resource allocation in 14 blood stations in Gansu, the top three were laboratories A, B and I, and the last three were laboratories G, M and J. On the whole, the main issue was unreasonable structure of human resources: most laboratories had unreasonable age structure; except for Laboratory A, there was no personnel with bachelor's degree or above in laboratories; most laboratories had not established a team with intermediate professional titles. In terms of infrastructure, the size of seven laboratories could not meet the needs of modern laboratory testing, and all eight blood stations had no spare nucleic acid laboratories nor a mutual spare laboratory with other blood stations As for the key equipment, 5 laboratories had no automatic blood grouping diagnostic instrument, 5 laboratories only had one set of enzyme immunoassay detection system, 3 laboratories had no spare equipment for the key equipment, which means if the equipment failure could not be repaired in time, the release of results would be affected. 【Conclusion】 There were significant differences in human resources, infrastructure and key equipment of blood testing laboratories in 14 blood stations in Gansu, which had a great impact on laboratory testing capacity and subsequent development. It is suggested that governments at all levels and health administrative departments optimize the input of laboratory resource allocation according to the blood collection volume of blood stations to gradually narrow the differences in resource distribution between different regions, improve the degree of laboratory automation and optimize the personnel structure, so as to build high-quality and efficient blood testing laboratories and ensure the safety of clinical blood use.
ABSTRACT
【Objective】 To evaluate the anti-HCV detection ability of our laboratory, and explore the factors that may affect anti-HCV detection, so as to provide data and basis for the evaluation of laboratory ability. 【Methods】 The number of initial reactive (IR) and repeated reactive(RR)samples and the reagent utilization rate in anti-HCV from 2019 to 2020 were compared with the national reagents of the same group. 【Results】 1)The average unqualified rate of anti-HCV detection was 0.25%, with the lowest rate at 0.19%, 33/17 774, and the highest rate at 0.37%, 44/11 940; 2)The retest rates of reagent 1 and reagent 2 were significantly different (P 0.05), while the RR/IR rates of reagent 1 and reagent 2 showed a slow upward trend; 4)The solo reagent unqualified rate of reagent 1 and reagent 2 showed statistically significant difference (P < 0.05); 5)The reagent utilization rate was basically the same as the national average level of reagents in the same group. 【Conclusion】 The anti-HCV detection indicators of our laboratory are relatively stable, but other factors such as personnel training, equipment performance and environment also have an impact on the detection ability of laboratories. Fine management of various element should be carried out, and external quality assessment reports of blood testing laboratory should be analyzed to further improve the anti-HCV detection ability of the laboratory.
ABSTRACT
Objective To study the effect of shortening the time of initial oral intake and fluid intake after general anesthesia in patients receiving oral and maxillofacial surgery on promotion of postoperative recovery. Methods A total of 116 patients were divided into the control group and the observation group with 58 cases in each group by random digit table from January 2014 to December 2015. Patients in the control group were allowed to take food orally 6 h after they regain analepsia from anesthesia;while those in the observation group were allowed to drink water after 2 h upon analepsia from anesthesia and take liquid food after 4 h. The mis-aspiration, the fasting glucose, blood pressure, heart rate and the rate of hunger, thirst, nausea, vomiting as well as blood pressure and heart rate were observed. Results The rates of hunger, thirst, nausea, vomiting in the observation group were 17.2%(10/58), 5.2%(3/58), 12.1%(7/58), 1.7%(1/58), which were significantly lower than those in the control group, which were 94.8%(55/58), 91.4%(53/58), 36.2%(21/58), 10.3%(6/58), and there were significant differences(χ2=7.484-54.772, all P<0.05). The fasting plasma glucose level in the observation group [(4.93 ± 0.85)mmol/L] was higher than that in the control group [(4.05 ± 0.51)mmol/L],and there was significant difference(t=-7.152, P<0.05). There were significant differences in blood pressure 3 h and 5 h after operation compared with those of the control group(P<0.05). Conclusions Shortening the time of taking food for patients undergoing oral and maxillofacial surgery can relieve uncomfortable symptoms , prevent hypoglycemia and the hemodynamic disturbance after anesthesia and promote recovery,early postoperative feeding should be suggested on the premise that they are fully awake.
