Abstract:
Objective To investigate the effect of liquid flushing lines in different temperatures and blood return in heparin-free hemodialysis patients.
Methods A total of 100 heparin-free hemodialysis patients (300 times in total) were selected as study objects, and the 300 times of cases were divided into conventional group and experimental group according to the random number table method, with 150 times in each group. Normal saline at room temperature was used in the conventional group to flush the pipeline and return blood, and normal saline heated to 37 ℃ was used in the experimental group (normal saline was prepared in the 37 ℃ incubator in advance) to flush the pipeline and return blood. The liquid temperature, the number of liquid flushing lines, the coagulation and residual blood volume of dialyzer and blood lines, nursing comfort, physical discomfort and nursing satisfaction of the two groups were compared.
Results Compared with the conventional group, the liquid temperature of the flushing line, the liquid temperature before blood return and the liquid temperature in the venous kettle in the experimental group were significantly increased (P < 0.05). The flushing times of experimental group was less than that of the conventional group, and the coagulation condition of dialyzer and blood pipeline was better, and residual blood volume of dialyzer and blood pipeline was less than that of conventional group (P < 0.05). The patients in the experimental group did not have cold upper limbs, body chills and other phenomena. Nursing comfort and nursing satisfaction in the experimental group were higher than those in the conventional group (P < 0.05).
Conclusion The use of normal saline heated to a suitable temperature(37 ℃) to flush the pipeline and return blood can effectively improve the comfort of patients with heparin-free hemodialysis, reduce the occurrence of low temperature in the upper limb and cold in the body, improve the clotting condition of the pipeline, reduce the number of flushing pipes and residual blood volume, and improve the patient's nursing satisfaction.
