  • Title: Arterial access in infants and children.
    Author: Cilley RE.
    Journal: Semin Pediatr Surg; 1992 Aug; 1(3):174-80. PubMed ID: 1345485.
    Abstract:
    Intraarterial access is used to provide continuous monitoring of systemic arterial blood pressure and to provide access to sample arterial blood. The use of chronic indwelling arterial catheters became commonplace in the 1970s and was rapidly adapted to the care of infants and children. The placement of intraarterial catheters can be technically challenging for even the most experienced surgeon, especially in small infants. Arterial catheters can directly injure vessels, resulting in thrombosis or occlusion. Distal embolization or ischemia can also occur. Catheter flushing may cause retrograde flow with the potential for embolization at remote sites. Local insertion site complications, such as hematoma, hemorrhage, and infection, can occur. Arterial catheters can also be a source of systemic sepsis. Although the risks and complication rates are low, the potential for devastating injury exists and deserves the greatest respect whenever placement of an arterial catheter is contemplated.
