- Peripheral Intravenous Catheter (PIVC): This is the most common and least invasive method of IV access. Anesthesiologists carefully select an appropriate peripheral vein in the patient’s arm or hand and insert a small plastic catheter into the vein. PIVC is relatively quick to insert and causes minimal discomfort. Newer options, such as smaller-gauge catheters and devices with improved insertion techniques, make the process more comfortable for patients.
- Midline Catheter: A midline catheter is a longer catheter that extends from the peripheral vein to a larger, more central vein. It provides a more stable and durable IV access option for patients requiring repeated or prolonged chemotherapy. Anesthesiologists can place midline catheters under ultrasound guidance, ensuring accurate positioning and minimizing discomfort for the patient.
- Central Venous Catheter (CVC): CVCs are inserted into large veins near the heart, such as the subclavian or jugular veins. These catheters offer long-term access and can accommodate higher flow rates for chemotherapy infusion. Anesthesiologists, often in collaboration with interventional radiologists, use imaging guidance to safely place CVCs. Newer CVC technologies, such as ultrasound-guided placement and tunneled catheters, enhance patient comfort and reduce the risk of complications.
- Peripherally Inserted Central Catheter (PICC): A PICC line is a long catheter that is inserted into a peripheral vein and advanced to a central vein, usually terminating near the superior vena cava. PICC lines offer a convenient and less invasive alternative to CVCs for patients requiring extended IV access. Anesthesiologists can place PICC lines under ultrasound guidance, minimizing patient discomfort and ensuring accurate tip positioning.
- Port-a-Cath: A Port-a-Cath, also known as an implanted port, is a small device that is placed beneath the skin. It consists of a reservoir connected to a catheter that is inserted into a central vein. Anesthesiologists, along with interventional radiologists or surgeons, can implant Port-a-Caths using local anesthesia. The device provides long-term, discreet IV access, and patients can receive chemotherapy and other medications by simply accessing the port with a special needle.
Anesthesiologists work closely with the oncology team to determine the most appropriate IV access option for each patient based on their treatment needs, expected duration of therapy, and individual circumstances. The goal is to ensure effective and comfortable IV access while minimizing the potential for complications and maximizing patient comfort during their cancer treatment journey.
