Venous Access

The goal of this clinical trial is to determine whether shorter periods of immobilization and bed rest after femoral venous interventional procedures can be safely used in adult patients undergoing peripheral venous interventions through femoral venous access. The main questions it aims to answer are: 1. Do shorter periods of immobilization and bed rest increase the risk of femoral venous access-site bleeding-related complications, including bleeding and hematoma? 2. Can shorter periods of immobilization and bed rest improve patient comfort, reduce back pain and anxiety, and allow earlier mobilization? Researchers will compare three postprocedural management strategies: 2 hours, 4 hours, and 8 hours of total immobilization and bed rest, to evaluate their safety and effects on patient recovery and comfort. Participants will be randomly assigned to one of the following three groups: 2-hour group: the puncture-side leg will be kept strictly immobilized for 0.5 hour, followed by 1.5 hours of bed rest. 4-hour group: the puncture-side leg will be kept strictly immobilized for 2 hours, followed by 2 hours of bed rest. 8-hour group: the puncture-side leg will be kept strictly immobilized for 4 hours, followed by 4 hours of bed rest. During strict immobilization, the puncture-side leg must remain extended and still. During the subsequent bed-rest period, small position adjustments and gentle movements in bed are allowed, but participants may not stand or walk. Participants will be monitored for puncture-site bleeding and other complications and will complete assessments of comfort, pain, and anxiety after the procedure.
