Abstract:
Objective:To compare the effects of two different calcium supplementation pathways in hemofiltration patients treated with citrate anticoagulation.Methods:Totally 30 critical patients undergoing hemofiltration in Peking University Third Hospital from April 2018 to March 2019 were selected using convenient sampling, and randomly divided into peripheral vein group ( n=15) and central vein group ( n=15) according to the random number table. Patients in the peripheral vein group received calcium supplements through the peripheral vein, while patients in the central vein group received calcium supplements through the central venous hemofiltration catheter. Blood gas analysis was used to monitor the control rate of serum ion calcium concentration of the patients at 2, 4, 6 and 8 hours after the hemofiltration machine was started, and the incidence of adverse reactions was compared between the two groups. Results:Blood gas analysis showed that there was a statistically significant difference in the control rate of serum calcium ion concentration between the two groups at 2 hours after the hemofiltration machine was started ( P<0.05) , and the rate of calcium supplementation through the central venous hemofiltration catheter was faster. At 4, 6 and 8 hours after the hemofiltration machine was started, there was no significant difference in the control rate between the two groups ( P> 0.05) . During hemofiltration, phlebitis or catheter obstruction did not occur in either group. Conclusions:Both calcium supplementation pathways are safe. When citrate anticoagulation is used in hemofiltration patients, the efficiency of calcium supplementation through the central vein is higher. The patients' blood calcium should be monitored when the hemofiltration machine is used for either pathway to prevent hypocalcemia.
