Alternative techniques for gaining venous access. What to do when peripheral intravenous catheterization is not...

There are a number of therapeutic options for fluid administration in patients who lack usual venous access. Ways to establish this access include limb elevation and wrapping, the application of nitroglycerin ointment to dilate veins, and blood pressure cuff inflation. Ultrasonography can also be used to delineate vascular structures. Cutdown procedures are the oldest, most direct method to reach uncommon venous sites, such as the inferior epigastric, intercostal, iliac, and lateral thoracic veins. Today, cutdown procedures are regarded as the method of last resort, and they should be performed in operating suites or similar settings. Possible complications include inadvertent arterial puncture and hemorrhage.
