The Effect of Heparin Concentration of 1000 units per ml in Blood Samples on the Results of Venous Blood Gases intensive care unit patients

Determining the effect of heparin concentration of 1000 units per ml in blood sample on venous blood gas results of patients admitted to intensive care unit

clinical trial with control group, with parallel groups, one-way blind, on 282 samples by non-random sampling method and available

Intravenous blood samples are taken from 282 (n = 141 intervention group and n = 141 control groups) patients admitted to the intensive care unit of 22 Bahman Hospital in Neishabour. Syringes are placed in two groups of heparin 1000 units and heparin 5000 units. An equal number of insulin syringes will be heparinized by the researcher in one group (A) with 1000 units of heparin solution (0.5 cc) and the other group (B) with 5000 units of heparin with the same amount (0.5 cc) of heparin. (50 units per syringe) will be divided into two insulin syringes heparinized with codes A (heparin 1000 units) and B (heparin 5000 units) that only the researcher knows the nature of. Not given to the analyzer and the answers are compared with each other.

Satisfaction to participate in the study Patients admitted to the cardiac intensive care unit Age 60-18 years Hemoglobin level more than 10 mg per deciliter There coagulopathy or anticoagulant treatment of moderate to high dose Death or discharge from the ward

An equal number of insulin syringes were heparinized in one group (intervention group) with 1000 units of heparin solution at a rate of 0.1 cc. In the control group, based on the current situation, an injection of 5000 units of heparin in the amount of 0.1 ml will be used to impregnate the insulin syringes used for blood sampling to perform venous blood gas tests.

First, all participants will be explained how to implement the project. The syringes will then be placed in two groups of heparin 1000 units (heparinized syringes with 1000 units) and heparin 5000 units (the common method of heparinized syringes with heparin is 5000 units). An equal number of insulin syringes will be heparinized by the researcher in one group (A) with 1000 units of heparin solution (0.05 cc) and the other group (B) with 5000 units of heparin with the same amount (0.05 cc). They will be divided equally by the researcher (0.5 cc or 50 units per syringe) into two insulin syringes heparinized with codes A (heparin 1000 units) and B (heparin 5000 units) that only the researcher knew about. It is then placed on ice and sent to the laboratory within 10 minutes, along with a test sheet that lists the necessary parameters (patient biography, body temperature, hemoglobin level, oxygen intake). A laboratory that does not know the amount of heparin in the syringes is given to the analyzer.
