Risk of Procedural Hemorrhage

Critically ill and hospitalized patients often require invasive procedures as a part of their medical care. Each procedure carries a unique set of risks and associated complications, but common to all of them is the risk of hemorrhage. Central venous catheterization, arterial catheterization, paracentesis, thoracentesis, tube thoracostomy and lumbar puncture constitute a majority of the procedures performed in hospitalized patients. We will discuss the risk factors for bleeding complications from each of these procedures and methods to minimize risk. The correction of coagulopathy prior to procedures is often employed by clinicians to decrease bleeding risk, but there is minimal evidence to support this practice.
