Too fast administration of a solution for parenteral nutrition (PP), including Oliklinomel N4-550E, can lead to severe consequences and death.
When there are objective or subjective manifestations of an allergic reaction(eg, sweating, fever, chills, headache, skin rash, dyspnea, bronchospasm) at the beginning of the drug, its administration should be stopped immediately. This medication contains soybean oil and egg phosphatides. Soy and egg proteins can cause hypersensitivity reactions. Cross-allergic reactions between soy and peanut proteins are described.
At the beginning of intravenous infusion, careful monitoring of the patient's condition is necessary. Before the start of infusion should be done correction of violations of water and electrolyte balance, conditions of severe volume overload and severe metabolic disorders.
Do not inject other drugs and substances into separate chambers and into the finished emulsion, without having data on the compatibility of these components and their effect on drug stability (in particular, on the stability of the lipid emulsion). Excessive addition of calcium and phosphorus can lead to the formation of calcium phosphorus precipitates. These precipitates, as well as the destabilization of the lipid emulsion, can cause the vessel to occlude.
In patients receiving PP, complications such as infection at the site of injection and sepsis are possible,which arise, in particular, with insufficient care of the catheter, due to the immunosuppressive effect of the disease or drugs. Recognize the infection at an early stage will help close monitoring of symptoms and laboratory tests for the onset of fever and chills, leukocytosis, technical problems with medical devices used for input, as well as hyperglycemia. Patients who require PP are often prone to infectious complications due to nutritional deficiencies and / or due to a condition caused by the underlying disease. The frequency of septic complications can be reduced by strictly observing aseptic measures during catheter placement, in the care of it, and also when preparing the drug for PP.
In the course of therapy necessary to control fluid and electrolyte balance, serum osmolarity, concentration of serum triglycerides, acid-base balance, the concentration of glucose in the blood, liver and kidney samples, the sample and coagulation of the blood, including the number of platelets.
If the supply of nutrients is not adapted to the needs of the patient or metabolicthe capacity of any component of the diet is not accurately determined, complications from the metabolism are possible. Unwanted metabolic phenomena may occur when an inadequate or excessive amount of nutrients is introduced, or when the composition of the finished mixture does not match the needs of a particular patient.
In the case of hyperglycemia, the rate of infusion of the drug and / or the introduction of insulin should be adjusted.
Despite the fact that the drug is allowed to enter the peripheral vein (due to low osmolarity), the development of thrombophlebitis is possible. It is necessary to examine the site of the catheter every day for signs of thrombophlebitis. The concentration of triglycerides in plasma and the ability to remove lipids from the bloodstream should be regularly assessed.
The concentration of serum triglycerides during infusion should not exceed 3 mmol / l. Their concentration should be measured no earlier than 3 hours after the start of the infusion.
If you suspect a disorder of lipid metabolism, it is recommended to repeat the same tests 5-6 hours after stopping the administration of the emulsion.In adults, the "cleansing" of serum (elimination of lipids) should occur less than 6 hours after stopping the infusion of the lipid emulsion. The next infusion should be performed only after the concentration of triglycerides in the plasma is normalized.
With the introduction of additional nutrients, the osmolarity of the resulting mixture should be measured before the infusion begins. The resulting mixture must be administered through a central or peripheral venous catheter, depending on the final osmolarity. If the finished mixture is a hypertonic solution, when injected into the peripheral vein, it can cause irritation of the vein walls.
Although the composition of the drug includes vitamins and trace elements in the usual concentration, their content is still not enough to meet the needs of the body, so they should be added to prevent deficient conditions. The resumption of feeding of patients with severe depletion can cause a renewal syndrome, which is characterized by an intense intake of potassium, phosphorus and magnesium ions into the intracellular space, in patients the processes of anabolism improve.Possible development of thiamine deficiency and fluid retention. These complications can be avoided through careful dynamic observation and a gradual, but not excessive, increase in the intake of nutrients. This syndrome is described for similar drugs.
Liver failure
It should be used with caution in patients with hepatic insufficiency because of the risk of developing or exacerbating neurological disorders associated with hyperammonemia. It is necessary to conduct regular clinical and laboratory tests, in particular on the concentration of glucose and triglycerides in the blood, the content of electrolytes and check the biochemical parameters of liver function.
Renal insufficiency
It should be used with caution in patients with renal insufficiency, especially in the presence of hyperkalemia, because of the risk of developing or exacerbating metabolic acidosis and hyperaemiaemia, if there is no adrenal cleansing. These patients need to carefully monitor the water-electrolyte balance and the concentration of triglycerides.
Blood disorders
It should be used with caution in patients with coagulation disorder blood and anemia. Careful monitor hemogram and indicators coagulation.
Disorders from the endocrine system and metabolism
It should be used with caution in patients with the following conditions:
- metabolic acidosis. In the case of lactic acidosis, the use of carbohydrates is not recommended. Clinical and laboratory tests should be performed regularly;
- diabetes. It is necessary to control the concentration of glucose, glucosuria and ketonuria and, if necessary, adjust the doses of insulin;
- hyperlipidemia due to the lipid content of the emulsion for infusion. Clinical and laboratory tests should be performed regularly;
- disturbances in the metabolism of amino acids.
Special instructions for use in pediatrics
Studies of the drug in children have not been conducted. When choosing a dose should focus on the age of the child, protein and energy needs, attacks on the disease. If necessary, enterally proteins and / or "energy" components (carbohydrates, lipids) should be added.
With parenteral nutrition in children older than 2 years, it is advisable to choose the volume of the container in accordance with the daily dose.
It is necessary to add vitamins and trace elements in doses, always used in pediatrics.
