Description
Vacutainer or butterfly needle systems used for venous blood collection provide secure venous access for diagnostic testing, transfusion sampling, and therapeutic phlebotomy, with selection based on vein size, patient age, and sample volume. Proper technique includes site selection, antiseptic skin preparation, correct angle of insertion, and gentle handling to avoid hemolysis or patient discomfort, followed by appropriate labeling and transport of specimens. Special considerations apply for pediatric, geriatric, and difficult venous access patients, where smaller gauge needles or ultrasound guidance may be used. Adherence to infection control practices, sharps disposal, and documentation ensures safety for patients and staff.
