ABSTRACT
OBJECTIVE@#To investigate the effect of continuous renal replacement therapy (CRRT) on patients with emergency and serious diseases.@*METHODS@#The patients were divided into 2 groups: Group A [71 patients with multiple organ dysfunction syndrome (MODS)] were treated by CRRT for 175 times. Group B (30 patients) were treated with common hematodialysis (HD). Blood urea nitrogen (BUN), serum creatinine (Scr), natrem (Na(+)), kalium (K(+)), chlorine (Clj), power of hydrogen (pH), bicarbonate (HCO3-), carbon dioxide partial pressure (PCO(2)), and oxygen pressure (PO(2)) were measured before and after the treatment.@*RESULTS@#After the treatment, all patients' general state of health, water-electrolyte and acid base disorder were improved. The levels of BUN, Scr, K(+) (All P(s)<0.01), and Na(+) (P<0.05 in Group A, P<0.01 in Group B) were all lower and the levels of CO(2)CP (P<0.01 in Group A, P<0.05 in Group B) were higher than that before the pretherapy in both Group A and Group B. There was significant difference on the levels of BUN, Scr, K(+)(All P(s)<0.01), Cl(-) and CO(2)CP (All P(s)<0.05) between Group A and Group B, which indicated the therapeutic effect in Group A was better than that in Group B. Furthermore, the levels of pH, PO(2) and HCO(3)(-) were higher (P<0.01) and PCO(2) was lower (P<0.05) obviously than that before the CRRT in 30 patients with acute respiratory distress syndrome (ARDS) in Group A. Among the 9 patients with poisoning, 7 were alleviated completely and 2 died after the CRRT plus hemoperfusion (HP). The survival time of patients was lengthened in Group A. No blood or bleed aggravation occurred in patients with bleeding inclination or 48 h before the operation after using the method of heparin soaking the blood filter.@*CONCLUSION@#CRRT has better curative effect on removing the toxin effectively, rapidly correcting the turbulence of water electrolyte and sour-alkali balance for patients compare with HD. At the same time, it can increase the level of PO(2) and reduce CO(2) retention, improve the lung function and brain edema, and increase the patient's survival rate. Using CRRT as early as possible is very important and it can improve the prognosis of the patients who had MODS or other dangers because the death rate of MODS patients is very high.
