Effects of time of bed rest on vascular complications after cardiac catheterization in pediatric patients with congenital heart disease: A randomized controlled trial

Background: Pediatric cardiac catheterization, which is performed by accessing the femoral vessel, requires immobilization and bed rest for 4-6 h to prevent vascular complications. Studies in adults suggest that the immobilization time for the same access can be safely reduced to approximately 2 h after catheterization. However, it is unclear whether bed-rest time can be safely decreased after catheterization in children. Objective: To assess the effects of bed-rest duration on bleeding, vascular complications, pain level, and the use of additional sedatives after transfemoral cardiac catheterization in children with congenital heart disease. Methods: This study was an open-label, randomized, controlled, posttest-only design, including 86 children who underwent cardiac catheterization. Children were allocated to receive either 2 h of bed rest (n = 42) in the experimental group or 4 h of bed rest (n = 42) in the control group following catheterization. Results: The mean age of children was 3.93 (+/- 3.82) years in the experimental group and 5.63 (+/- 3.97) years in the control group. There was no difference in site bleeding incidence (P = 0.214), vascular complication score (P = 0.082), pain level (P = 0.445), or additional sedation use (P =1.000) between the two groups. Conclusions: There were no significant hemostatic complications after 2 h of bed rest following pediatric cath-eterization; therefore, 2 h of bed rest was as safe as 4 h of bed rest.
