BACKGROUND: Portable blood glucose meters are the main method for detecting the blood glucose status of clinical patients. OBJECTIVE: To investigate the accuracy of detecting blood glucose in haemodialysis patients by sampling two blood glucose meters through the haemodialysis line. METHODS: Convenient sampling was used to select 80 patients with maintenance haemodialysis. The patients were sampled through the arterial end of the haemodialysis line within three minutes of being put on the machine. One specimen was tested by glycemeter1, which can identify the type of blood in the arteries and veins, and glycemeter2, which can only detect blood glucose in the capillaries for bedside blood glucose testing. The other specimen was sent to the laboratory biochemical analyser for blood glucose testing. RESULTS: When the blood glucose value of the first blood glucose meter (No. 1) was compared with the laboratory biochemical analyser, the correlation coefficient was r = 0.805 (p < 0.05), the out of value of the first blood glucose meter accounted for 4.4%, and the consistency reached 95% (p < 0.05). When the blood glucose value of the second blood glucose meter (No. 2) was compared with the laboratory biochemical analyser, the correlation coefficient was r = 0.800 (p < 0.05), the out of value of the second blood glucose meter accounted for 4.4%, and the consistency reached 95% (p < 0.05). CONCLUSIONS: For patients with maintenance haemodialysis, the blood glucose values detected by the two bedside blood glucose meters using arteriovenous mixed blood in the pipeline do not affect the accuracy and can respond more realistically.
OBJECTIVE:The aims of this study were to observe the regularity of blood glucose changes in hemodialysis patients with diabetes, time of onset of hypoglycemia and blood glucose level during dialysis, and to explore the sensitive early warning indicators of hypoglycemia in dialysis patients.BACKGROUND: Diabetes patients have a high incidence of hypoglycemia during hemodialysis.METHODS: A total of 124 maintenance hemodialysis patients with diabetes were selected for this study. Before dialysis, one, two, and three h after dialysis, and when hypoglycemia symptoms occurred, the blood glucose changes were monitored, the blood glucose drop range was observed when hypoglycemia symptoms occurred, and the correlation between the two was analyzed.
RESULTS:After the start of the dialysis, the patient's blood glucose showed a downward trend. The symptoms of hypoglycemia were most obvious within one-two hours, with an incidence rate of 57.9%. When the blood glucose drop percentage reached 37.7%, the specificity and sensitivity of early warning hypoglycemia symptoms were 84.6 and 73%, respectively. CONCLUSIONS: For hemodialysis patients with diabetes, attention should be paid to the symptoms of hypoglycemia during dialysis, and blood glucose should be monitored before dialysis and after 1-2 h of dialysis. If the blood glucose drop percentage is greater than 37.7%, the timely measures should be taken.
