Emergency vascular access.

Abstract

Establishing and maintaining vascular access is often vital to the preoperative, intraoperative, and postoperative management of the small animal emergency surgical patient. Vascular access may be used for the delivery of crystalloids, colloids, blood components, medications, and anesthetic or sedative agents. It can also facilitate venous and arterial blood sampling and allow direct measurement of arterial and venous pressures. The small animal emergency and critical care veterinarian should have a thorough knowledge of vascular access techniques, including peripheral and central venous catheterization, intraosseous, and arterial access. Competence in percutaneous, percutaneous facilitative, and surgical cutdown approaches should ensure that vascular access can always be established in the critically ill patient.
