Chapter 61 Peripheral Venous Catheterization
• There are four primary catheter types: winged, over-the-needle, through-the-needle, and multilumen.
• Catheter insertion site selection depends on several factors, including vessel availability and the intended purpose of catheterization.
CATHETER TYPES
A variety of catheters are commercially available (Figure 61-1). The length and gauge (diameter) of the catheter to be used are dependent on the species and size of the patient, the veins available and their condition, and the needs of the patient.
