About

Coronary Artery Disease (CAD) is the most common cardiovascular system disease. According to the World Health Organization data, CAD ranks first among the top 10 causes of death. According to the 2014 data of the Turkish Statistical Institute (TUIK), deaths due to circulatory system diseases are in the first place with 40.4%, and 39.6% of this is ischemic heart diseases. The prevalence of CAD in Turkey is 12% in women and 14% in men. The diagnosis of CAD is largely made on non-invasive tests. Coronary angiography (CAG) is recommended for definitive diagnosis and detection of coronary stenosis. CAG is defined as the manual delivery of contrast material through a catheter sent to the coronary arteries under fluoroscopy and recording the resulting image on a CD. With special catheters advanced through a plastic sheath called a sheath placed in the access tract, contrast agents are administered separately to the left main coronary (LDA) and right main coronary arteries (RCA), and images of the coronary arteries are taken in multiple positions.

Complications related to diagnostic and therapeutic CAG are rare, but vary according to the patient's condition, operator's experience, and the type of procedure. The most common vascular complications are bleeding, hematoma, ecchymosis, pseudoaneurysm, retroperitoneal hemorrhage, arteriovenous fistula. Preventing complications before they develop is actually shown as the most successful treatment. For this reason, it is recommended to use a small-diameter catheter during CAG, to enter the main femoral artery carefully, to interrupt anticoagulant treatment before the procedure, to apply manual compression to the area for at least 20 minutes after the procedure, and to use percutaneous closure devices, which is another method. After the procedure, pressure is applied with a sandbag, manual compression, and a pneumatic compression device. In the sandbag method, a 3-4.5 kg sandbag is placed after the bleeding is controlled by manual pressure on the femoral region where the intervention is made. During this period, the patient's movements are restricted and he is asked to lie flat on his back. In the use of the pneumatic compression device, a pneumatic compression device (closepad) with a transparent window and balloon incision is placed to maintain the compression on the femoral artery after a short period of manual compression. However, it is not preferred because of the risk of embolism and high cost.

In addition to pressure applications, local cold application is effective in preventing perivascular complications. Cold application controls bleeding by reducing capillary blood flow and capillary permeability by vasoconstriction of arterioles. In addition, it reduces the flow rate of the blood and increases its viscosity, thereby making it coagulate. It controls bleeding by blood coagulation, reduced capillary permeability and metabolic requirements. This situation reduces the development of ecchymosis and hematoma. Considering this information, cold application can be preferred for the prevention of hematoma and ecchymosis, which are the most common complications after CAG, because it is practical, inexpensive and comfort-enhancing. The number of studies in the literature in which cold application and pressure application are used together is limited. Based on this information, the current study was planned to evaluate the effectiveness of cold pressure application for the prevention of hematoma and ecchymosis in the CAG intervention area. The hypotheses of the research; H0: Cold pressure application has no effect on the prevention of hematoma and ecchymosis in the CAG intervention area.

H1: Cold pressure application has an effect on the prevention of hematoma and ecchymosis in the CAG intervention area.

IU/kg) Place and time of research The research will be carried out in Eskişehir City Hospital Cardiology and Coronary Intensive Care 1,2 services between Nowember 01, 2021 and June 01, 2022.

Eskişehir City Hospital Cardiology Service: It started to serve in October 2018. In the 24-bed cardiology service, patients with diagnoses such as heart failure, rhythm disorder, and chest pain are generally hospitalized. The number of physicians is 10. The number of nurses is 11.

Eskişehir City Hospital Coronary ICU 1 Service: It started to serve in October 2019. In the 8-bed Coronary Intensive Care 1 Service, patients with diagnoses such as heart failure, arrhythmia, chest pain are generally hospitalized. The number of physicians is 10. The number of nurses is 10.

Eskişehir City Hospital Coronary ICU and 2 Service: It started to serve in November 2018. In the 10-bed cardiology service, patients with diagnoses such as heart failure, arrhythmia, chest pain are generally hospitalized. The number of physicians is 10. The number of nurses is 15.

The standard CAG procedure treatment and follow-up process applied to all patients in Eskişehir City Hospital Cardiology and Coronary Intensive Care 1,2 services are as follows; Standard monitoring and care;

It is questioned whether the patient has antiplatelet and anticoagulant use.
The patient who comes to the Angio laboratory is monitored by the nurse. Vital signs are recorded. At the same time, the patient is connected to a defibrillator and defibrillation is provided in case of fatal rhythm.
Under local anesthesia, an incision is made in the intervention area by the physician, sheath is advanced to the femoral artery, and the coronary arteries are visualized by means of radiopaque material.
When occlusion or stenosis in the coronary arteries is seen by the physician, balloon and/or stent operation is performed. During these procedures, clarification is provided by using drugs such as heparin, perliganit, clotinab. Sheat extraction is done at the time prescribed by the physician.
If the coronary arteries are seen as open, sheath is removed and the patient is brought to the service or intensive care unit.
After sheat extraction, manual compression is done for a minimum of 15 minutes.
Rolled gauze with a diameter of 5 cm is placed on the intervention area.
A sandbag is placed on the patient's intervention area and immobilized. The sandbag is kept in the intervention area for 4 hours.
The patient, whose CAG procedure is completed, is taken to the bed in the ICU or the ward by the nurse, his vital signs are evaluated, an EKG is taken, and the rhythm is followed.
The intervention area is checked hourly by the nurse in terms of vascular complications, pulse, temperature, color change.
The time of sheat extraction and sandbag removal, vascular complications in the intervention area and vital signs are recorded by the nurse.
The treatment ordered by the doctor is applied. The universe and sample of the research The population of the study is the patients who were followed up after CAG in Eskişehir City Hospital Cardiology Service and Coronary Intensive Care 1,2 Services. The sample is the patients who meet the sample selection criteria within the specified population. Sample selection criteria;
over 18 years old
Conscious
Patients who underwent CAG for the first time and/or did not undergo CAG in the last 1 year (it is stated that the recovery period in the femoral intervention area after CAG is completed in 3 months (54). Based on this information, in the study, patients who had CAG before had at least 1 year from CAG. criteria have been determined),
Platelet values within normal limits,
Patients treated with 10,000 units or less of heparin during angiography. Exclusion criteria from the study;

Those with peripheral vascular disease. In determining the number of samples in the study, the sample number was calculated as 210 units, 105 units in the SBG group and 105 units in the NBG, based on the results of the study conducted by Güleser (2011)(55) Data collection method The patients who meet the sampling criteria within the scope of the study will be informed verbally and in writing by the researcher before the CAG procedure and the "Voluntary Consent Form" prepared by the researcher will be signed (Appendix-1). The Individual Identification Form will be filled in by using face-to-face interview technique for all patients. Within the scope of the study, the randomization of the patients who meet the sample selection criteria will be made by an expert independent of the research, using the random numbers method obtained on the computer into two groups [cold pressure group (SBG) and normal pressure group (NBG)]. The specialist will deliver the registration order and the group numbers of the patients in a sealed envelope to the researcher who performed the application.

Procedure In addition to the standard treatment, follow-up and care applied for CAG in Eskişehir City Hospital Cardiology and Coronary Intensive Care services, the steps to be applied for SBG and NBG patients during the research are as follows; Cold pressure application: The following procedures will be applied to the patients in the cold pressure application group;

The temperature of the cold sandbag to be applied to SBG patients will be kept at 18-20 °C. For this, a sandbag will be placed in the freezer of the refrigerator in the clinic at least 2 hours in advance.
The surface temperature measurement of the cold sandbag taken out of the freezer will be checked with the surface mode of the thermometer and processed into the KAG follow-up form. In the preliminary application made by us regarding this process, the temperature of the sandbag remaining in the freezer for 2 hours and then removed is 18.1 °C in the 0th minute; 10. 19.3 °C per minute; It was determined that it was 19.5 °C in the 20th minute.
Cold pressure will be applied for 20 minutes by placing a cold sandbag on the patient's intervention area (56.57),
After 20 minutes, a cold ice pack will be removed and a room temperature sand bag will be placed. The sandbag at room temperature will be kept in the intervention area for 3 hours and 40 minutes.

Normal pressure application: The following steps will be applied to the patients in the normal pressure application group;

The sandbag to be used for NBG patients will be kept at room temperature and the surface temperature measurement of the sandbag will be evaluated with the surface mode of the thermometer. The detected heat will be recorded on the KAG tracking form.
Pressure will be applied to the intervention area of the patients by placing a sand bag at room temperature for 4 hours.

During the study, the treatment plan determined by the doctor will be applied to both groups of patients as specified, and no changes will be made in the treatment plan. Pressure will be applied to both groups of patients for 4 hours, and cold pressure will be applied only to SBG patients for the first 20 minutes. The CAG intervention area of all groups will be monitored and recorded for 24 hours with the CAG follow-up form. According to the CAG follow-up form, in both groups of patients;
