Background: Restoring patient homeostasis after coronary angiography, the gold standard diagnostic test for coronary heart disease is usually achieved by manual compression of the puncture site using a sandbag and prolonged bed rest. However, this process frequently results in patient complaints of back pain and discomfort.Purpose: The aim of study was to assess the effect of positioning on patient outcomes after coronary angiography.Methods: This study used a single-blind randomized control trial approach. The sample consisted of 80 patients who had undergone a nonemergency coronary angiography via the femoral artery. Balanced block randomization was used to allocate participants into intervention and control groups. Routine care for the intervention group (n=40) was adjusted to include the following: (1) intermittent changes to patient body and head position in bed during first 6 hours after catheterization, (2) reduction of sandbag compression time on the puncture site to 1 hour, and (3) regular examination for bleeding during the first 6 hours after catheterization. Intervention group participants were allowed to ambulate without restriction 6 hours after catheterization. Patients in the control group (n=40) received routine care, consisting of (1) 6-24 hours of bed rest in the supine position with the affected leg fixed straight and immobilized and (2) sandbag compression on the puncture site for 6 hours. The main outcomes used in this study were level of back pain, discomfort, foot pain, bleeding, and hematoma.Results: Intervention group patients had significantly less back pain and foot pain and higher comfort than the control group at the second, third, and sixth hour after catheterization (p=.00). There was no significant difference between the two groups in terms of amount of bleeding and hematoma (p＞.05).Conclusions: Findings suggest that changes in patient position may be safer in the early period of postcatheterization bed rest than currently indicated in standard practice protocols. Furthermore, limiting sandbag compression to 1 hour has no measurable effect on the incidence and severity of vascular complications.
