midlines

Midlines are a type of intravenous (IV) access line used primarily in medical settings to provide fluids, medications, or blood products to patients. They are typically inserted into a vein located in the midline of the body, which refers to the central line running down the middle of the torso. This placement helps ensure that the catheter remains in a stable position, reducing the risk of displacement or complications such as infection or thrombosis.

Midlines are commonly used in pediatric and neonatal care, as well as in surgical and critical care settings. They are often preferred over peripheral IV catheters for patients requiring long-term IV therapy, as they allow for easier access and maintenance. The catheter is usually inserted into a vein in the upper arm, forearm, or thigh, with the tip positioned near the heart to facilitate efficient delivery of fluids and medications.

Advantages of midlines include their ability to provide reliable access for multiple medications and fluids, their lower risk of complications compared to central lines, and their relative ease of insertion. However, they are not suitable for all patients, particularly those with certain vascular conditions or those requiring immediate, high-volume fluid resuscitation. Proper insertion techniques and ongoing monitoring are essential to minimize risks and ensure effective use.
