Survey the effect of bed-rest and sandbag on hematoma and hemorrhage after ‎coronary angiography

Introduction: Cardiovascular disease is one of the leading major causes of death in the world. ‎Coronary angiography is the most important routine diagnostic procedure for coronary artery ‎disease.‎ Objective: The aim of this study is to assess the effect of bed-rest duration time and sandbag ‎time on hematoma and hemorrhage after coronary angiography.‎ Methods: This study is a randomized clinical trial. Patients undergoing nonemergency ‎angiography via the femoral artery are randomly assigned into intervention (‎‏65‏‎ patients) or ‎control group (‎‏65‏patients). The patients in the intervention group are allowed to be out of bed ‎after ‎‏4‏‎ hours. The sand bags are taken off two hours later. The patients in the control group ‎received routine care. Hematoma and hemorrhage were measured at regular intervals after the ‎procedure.‎  Results: In intervention group bleeding occurred in one patient in four hour and one patient ‎immediately after coming to ward in control group. In intervention group hematoma occurred ‎in one patient in two hour and in control group one patient in one and two hours and two ‎patients in four hours. The Chi square test showed no statistically significant difference ‎between groups.‎  Conclusion: This study showed no relationship between increased chance of hematoma and ‎hemorrhage and bed-rest for four hours and sandbag applied for two hours in patients ‎undergoing angiography. ‎
