Brief summary

This study aimed to evaluate the effect of different durations of a specific pressure applied after blood collection on the development of ecchymosis in geriatric patients using oral and subcutaneous anticoagulants.

Detailed description

The research sample consisted of patients hospitalized in the Geriatrics Clinic of a city hospital. This study aimed to evaluate the effect of different durations of a specific pressure applied after blood collection on the development of ecchymosis in geriatric patients using oral and subcutaneous anticoagulants. In this study, whether ecchymosis developed at the 24th, 48th and 72nd hours after the blood collection procedure was evaluated.
