Can Modern Infusion Solutions Cause Serious Disruption of Inner Environment of an Organism?

The article brings a description of a patient case when an application of mineral balanced infusion solutions led to a disruption of inner environment, beginning of a combined failure of the acid- base balance with a serious metabolic acidosis. Patient J. was artificially respirated after a CPR. During the therapy the patient was given basically without any changes a combination of mineral solution Plasma-Lyte 148, amino-acid and 20% glucose. During 8 days a serious metabolic alkalosis had developed (caused by a lack of chlorides, phosphates and other reasons), combined with respirational acidosis. Hydrogencarbonate level was increased to 47.2 mmo/l (at norm of 24 mmol/l), base excess level to 21.4 mmol/l (at norm of 0 mmol/l). Metabolic acidosis led to reduction of sensibility of the respiratory centers and therefore it was not possible to restore spontaneous respiration. After the therapy change and reduction of metabolic acidosis the state of the patient got better. Application of acidifying solutions, supplementation of phosphate and potassium levels and replenishment of actual losses of phosphates led to regulation of the inner environment. Together with the application of sufficient amount of basic nutrients was the improvement of acid-base balance the key factor which enabled the restoration of spontaneous respiration and disconnection of the patient from the ventilator. In short summary you can see reasons which cause different effect of identical infusions to acid-base balance of the inmates in different situations. The article points to a necessity of controlling groovy medical procedures according to actual patient’s needs.
