Intravenous (IV) cannulation is one of the most essential clinical skills in healthcare, providing access for fluid therapy, medications, and blood sampling. While it may appear straightforward, mastering IV cannulation requires both technical proficiency and clinical judgment. For many students and practitioners, the skill can initially feel challenging due to patient variability, vein accessibility, and the fine motor coordination required. However, with focused effort and the right approach, it is a technique that can be consistently and confidently performed. Two key strategies stand out in developing expertise: regular, deliberate practice and the ability to identify and select the right vein. Together, these form the foundation of competence in IV cannulation.
