Testify patient's blood electrolyte concentration a tendency to approach that of replacement-fluid in continuous renal replacement therapy / 中华危重病急救医学

Objective To prove with mathematical formula that the patient's blood electrolyte concentration shows a tendency to approach that of replacement-fluid after continuous renal replacement therapy (CRRT).Methods Electrolyte concentration of plasma,replacement-fluid and returning fluid were compared,and they were labeled as Cblood,Cnom,and Creturn respectively.The Creturn was calculated,and the relationship among them was demonstrated with comparison by mathematical formula.At last,according to their relationship,plasma change towards to the replacement fluid was analyzed.Results It was showed that Cblood＜Creturn＜Cnom or Cblood＞Creturn＞ Cnom,and according the relationship,it was derive that the trend of change in Cblood after circulation for m unit time was Cblood1 ＞Cblood2 ＞Cblood3 ＞ … ＞Cbloodm ＞Cblood or Cblood1 ＜ Cblood2 ＜Cblood3 ＜ … ＜Cbloodm ＜Cnom.The plasma electrolyte concentration would close to that of replacement fluid infinitely with the continue of CRRT.Conclusions With mathematical model,it is proved that the replacement fluid electrolyte concentration is the final target of the plasma.We must make up the replacement fluid correctly.And this results provide the basis for CRRT treatment of electrolyte disorder.

Electrolyte disorder in heart failure patients

At Cho Ray Hospital – Ho Chi Minh city from Dec 2001 to Dec 2002, 228 heart failure cases (96 males, 130 females, aged 58.4317.45) were studied. Their associated conditions were: 14 with diabetes, 5 brain blood infactus, 5 hyperthyroidies, 19 kidney failures. Among 162 patients with electrolyte disorders, 25 were died, the rate of hyponatremia and hyperkalemia was significantly higher in fatal group than in survival group. Hyponatremia was fatal risk factor and it should pay great attention to treat this condition with hypertonic natrium solution

Analysis of Electrolyte Disorders of Fifty Infants with Severe Pneumonia / 中国医师杂志

Objective To study the electrolyte status of 50 infants with severe pneumonia. Method By means of retrospective way to analyze the electrolyte level of blood sample from 50 young children. Results The sequences of electrolyte disturbances in the 50 young children with severe pneumonia were hyponatremia(34%), hypokalemia(30%),hypocalcemia(18%),hypochloremia(16%),hypernatremia(12%),and heperkalemia(10%). Conclusion Young children with severe pneumonia often have electrolyte disturbances of various kinds at the same time; electrolyte evaluations of blood samples from such young children should be done routinely, so that problems can be found early, and correcting measures be taken in time.
