ICU procedures of the critically ill.

Intensive Care Unit (ICU) patients often require urgent, high-risk diagnostic and therapeutic procedures. However, they are particularly vulnerable to procedural complications due to the severity and instability of their illnesses. We discuss the complications associated with bronchoscopy, percutaneous dilatational tracheostomy, pleural interventions for example thoracentesis and chest tube placement, central venous catheterization and pulmonary artery catheterization. Invasive procedures are frequently performed in critically ill patients. It is important for the operator to be familiar with the specific complications of each procedure, as well as steps to take in order to enhance safety and reduce adverse events. High standards of training and credentialing are crucial to ensure that the ICU physicians are proficient in performing these procedures.
