haemofiltration fluid
What Duosol Potassium Free is and what it is used for
Duosol Potassium-free is a haemofiltration fluid. It is used for patients with acute renal failure, ie. as the kidneys can no longer eliminate waste products from the blood. Continuous haemofiltration is a method of eliminating the waste products that are normally excreted via the kidneys into the urine. The fluid corrects the fluid balance and replaces salts ( electrolytes ) lost in connection with the treatment.
2. What you need to know before you are given Duosol Potassium Free
You will not be given Duosol Potassium Free
- if you have an abnormally low level of potassium in your blood ( hypokalaemia )
- if you have an abnormally low level of acid in your blood ( metabolic alkalosis ).
Hemofiltration should not be used:
- if you have kidney failure in combination with very high metabolic turnover (hypercatabolism) where haemofiltration can no longer eliminate slag products that accumulate in the blood
- if you have poor blood circulation around the venous cannula
- if you have a high risk of bleeding due to the use of drugs that prevent the blood from clotting (systemic anticoagulation).
Warnings and cautions
Talk to your doctor or pharmacist before taking Duosol Potassium Free.
Before and during hemofiltration, your blood pressure, fluid, salt ( electrolyte ) and acid-base balance, and kidney function are checked. Blood glucose and phosphate levels are monitored regularly.
Also, the concentration of potassium in serum is checked before and during hemofiltration.
Other medicines and Duosol Potassium-free
Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines.
Your doctor will consider that the concentration of other drugs in your blood may decrease during hemofiltration.
Effects on other and other drugs ( interactions ) can be avoided with proper dosing of haemofiltration fluid and close monitoring of treatment.
The following interactions should be considered:
- Infusion given in intensive care can change the composition of your blood and fluid balance.
- The toxic effects of certain medicines used to treat heart failure (medicines containing digitalis ) may not be detected if the potassium or magnesium levels in your blood are too high or the calcium levels in your blood are too low. If these levels are corrected by hemofiltration, toxic effects can appear and cause, for example, abnormal heart rhythms. If you have low levels of potassium or high levels of calcium in your blood, digitalis can cause toxic effects at lower doses than those commonly used for treatment.
- D vitamins and medicines containing calcium may increase the risk of abnormally high blood calcium ( hypercalcemia ).
- Additional use of sodium bicarbonate may increase the risk of abnormally low levels of acid in the blood ( metabolic alkalosis ).
Pregnancy, breastfeeding, and fertility
If you are pregnant or breast-feeding, think you may be pregnant, or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.
At present, there is no information on the use of haemofiltration fluids during pregnancy. However, as all the ingredients in this medicine are naturally occurring substances that only replace substances lost by the body during haemofiltration, no risks to the baby during pregnancy and breastfeeding or any effects on fertility are expected.
Driving and using machines
This medicine is usually given to patients in a hospital/dialysis unit and this excludes the possibility of driving and using machines.
3. How to use Duosol Potassium Free
You will only be given this medicine under the guidance of a doctor who has experience in haemofiltration treatment.
Your doctor will prescribe the appropriate dose for you based on your clinical condition, your weight, and your metabolic condition. Unless otherwise specified, the recommended filtration rate is 20-25 ml/kg body weight/hour for patients of all ages to remove slag products normally excreted in the urine.
The ready-to-use liquid is given to you via a tubing system and with an infusion pump that belongs to the haemofiltration device (so-called extracorporeal circulation).
Acute renal failure is treated for a limited time and treatment is stopped when normal renal function has been restored.
If you take more Duosol than you should Potassium-free
No life-threatening events have been reported with the use of prescribed doses. Administration can be discontinued immediately if necessary.
Too much or too little can lead to too much or too little fluid in the body (hyperhydration or dehydration ). This can be detected by changes in blood pressure or heart rate.
Hydrocarbonate overdose may occur if too much hemofiltration fluid is given.
This can lead to abnormally low levels of acid in the blood ( metabolic alkalosis ), decreased amount of dissolved calcium in the blood (decrease in ionized calcium ), or muscle cramps.
Overdose can cause heart failure and/or blood clotting in the lungs and lead to changes in the salt balance (electrolyte balance) and acid-base balance.
The doctor prescribes appropriate treatment.
If you have any further questions on the use of this product, ask your doctor or pharmacist.
4. Possible side effects
Like all medicines, this medicine can cause side effects, although not everybody gets them
