Abstract:
Objective To observe the relationship between the follow-up total carbon dioxide(tCO2) levels and all-cause death in maintenance hemodialysis(MHD) patients.
Methods The follow-up data of MHD patients were collected, and the cardiovascular and all-cause death were observed.
Results Two hundred and seven patients were observed to the end point of follow-up, with a median follow-up time of 29(15, 36) months, and 37 patients had cardiovascular or all-cause death. The results of multivariate COX regression analysis showed that the follow-up tCO2 level ≤21.80 mmol/L, hypertension, and follow-up serum total calcium level were the independent risk factors of all-cause death in MHD patients(P < 0.05 to P < 0.01), the all-cause death in MHD patients with follow-up tCO2 level ≤21.80 mmol/L significantly increased(P < 0.01).
Conclusions The follow-up tCO2 level ≤21.80mmol/L is an independent risk factor of death in MHD patients. Monitoring the follow-up tCO2 level may predict the occurrence of all-cause death in MHD patients. Improving blood tCO2 level can reduce all-cause death in MHD patients.
