      <study_design>Randomization: Randomized, Blinding: Triple blinded, Placebo: Not used, Assignment: Parallel, Purpose: Prevention, Randomization description: The selection of the research samples is such that all the people hospitalized in special care units, who have the conditions to enter the study, are selected as the research sample. A table was prepared for the order of patients entering the study.
At first, 30 numbers from one to three, 30 numbers from four to six, and 30 numbers from seven to nine were selected from random.org/integers. Then, to randomize this list of 90 numbers, the part related to randomization of lists, website random.org/lists was used. In this way, the patients entering the study are assigned a random number that determines the relevant group. Numbers 1 to 3 are for the normal saline group (group A) and numbers 4 to 6 are grouped for the heparin group with a concentration of 30 units (group B) and numbers 7 to 9 are grouped for the heparin group with a concentration of 50 units (group C), Blinding description: Patients are not aware of their treatment method.
Based on the drug preparation protocol, the researcher prepares the studied solutions and codes them as A, B, C.
The interventionist (patient-specific nurse), without knowing the identity of these codes, injects solution A to patient A, and in the same way, the rest of the codes are also injected to the patient corresponding to their code.
The evaluator (patient-specific nurse) records the opening of the catheter with the corresponding specific code in the patient-specific form.</study_design>

      <i_freetext>Intervention 1: The first intervention group: In patients whose central venous catheter has been in place for less than 24 hours and who meet the conditions for entering the study, before clamping the central venous catheter, a solution of 30 units of heparin (Alborz Daru Company) in a volume of 2 cc every 8 hours inside Each duct is injected and locked, and then the duct is clamped.The central vein catheter channel is checked every 8 hours for the opening or blockage of the catheter by aspirating with a 10 cc syringe and observing the return of blood and fluids, as well as the presence of signs of infection and bleeding, and the result of the intervention is recorded. Intervention 2: The second intervention group: In patients whose central venous catheter has been in place for less than 24 hours and who meet the conditions for entering the study, before clamping the central venous catheter, a solution of 50 units of heparin (Alborz Daru Company) in a volume of 2 cc every 8 hours inside Each duct is injected and locked, and then the duct is clamped.The central vein catheter channel is checked every 8 hours for the opening or blockage of the catheter by aspirating with a 10 cc syringe and observing the return of blood and fluids, as well as the presence of signs of infection and bleeding, and the result of the intervention is recorded. Intervention 3: Control group: In patients whose central venous catheter has been in place for less than 24 hours and who meet the conditions for entering the study, before clamping the central venous catheter, they are flushed with a volume of 10 cc of normal saline every 8 hours and then The conduit is clamped. The central vein catheter channel is checked every 8 hours for the opening or blockage of the catheter by aspirating with a 10 cc syringe and observing the return of blood and fluids, as well as the presence of signs of infection and bleeding, and the result of the intervention is recorded.</i_freetext>
