Background: Acute kidney injury (AKI) requires continuous renal replacement therapy (CRRT), which is one of the most important problems in medical and surgical patients. Therefore, it is very important to identify the influencing factors to reduce the dimensions of the problem. This study was conducted to investigate the mortality rate in medical and surgical patients with AKI requiring CRRT treatment.
Materials and Methods: In this observational study, which was conducted as a cross-sectional analytical study, 100 patients with AKI requiring CRRT treatment, including medical and surgical patients, were selected from 2018 to 2021 at Masih Daneshvari Hospital. The mortality rate was estimated. Also, the effective factors were investigated and compared between the dead and surviving patients.
Results: 85 cases (85%) of the patients died. Most underlying and demographic variables had no statistically significant difference between the dead and surviving patients (P>0.05). However, in the cases of primary calcium (P=0.001), primary leukocyte (P=0.037), bicarbonate during hospitalization (P=0.025), bicarbonate during AKI (P=0.028), magnesium during hospitalization (P=0.038), and magnesium at the end of CRRT (P=0.019), the differences were statistically significant.
Conclusion: In conclusion, mortality is observed in 5 out of 6 patients with acute kidney failure who need CRRT treatment, which is related to risk factors such as bicarbonate, magnesium, leukocyte, and calcium levels. Therefore, multifaceted planning is needed to reduce its dimensions to improve the prognosis of this group of patients.
