Abstract
Placement and maintenance of vascular access comprise an important adjunct in the care of the critically ill obstetric patient. Arterial and venous access affords the clinician several diagnostic and therapeutic advantages. This requires knowledge of catheter types, access routes, insertion techniques, and maintenance. Three catheterization techniques are available to obtain vascular access: direct and either modified or classic Seldinger techniques. A wide range of immediate and delayed complications can be associated with central venous and arterial catheters. Catheter malposition can be a complication of any vascular cannulation. The radial artery is a favored site for arterial cannulation due to its superficial location medial to the styloid process. The brachial artery is the continuation of the axillary artery. Use of the brachial artery entails greater risks than use of the radial artery.
