Abstract
Introduction: Management of critically ill patients requires imaging techniques, which are essential for optimizing diagnostic and therapeutic procedures, the diagnosis and management of pneumothorax, pleural effusion and lung consolidation all require direct visualization of the lungs. To date, chest imaging has relied on bedside chest radiography and lung computed tomography (CT).
In the Intensive Care Unit (ICU), bedside chest radiography is routinely performed on a daily basis and is considered as a reference for assessing lung status in critically ill patients, limited diagnostic performance and efficacy of bedside portable chest radiography have been reported in several previous studies.
Although lung CT is now considered as the gold standard for the diagnosis and guiding therapeutic procedures in critically ill patients but to perform a lung CT scan requires transportation to the department of radiology, a risky procedure necessitating the presence of trained physicians and sophisticated cardio-respiratory monitoring. In addition helical multi-detector row CT exposes the patient to asubstantial radiation dose, which limits the repeatability of the procedure.
Recently, chest ultrasound can be used easily at the bedside to assess initial lung morphology in critically ill patients.
US guidance has emerged as an adjunct tool that can achieve successful placement of CVCs with fewer attempts and fewer complications. This methodology is now supported by a large body of evidence and will likely gain more acceptance among physicians as they acquire the necessary skills and realize its potential. Further research is necessary to weigh the effect of this technology on a patient’s quality of life and mortality and to discover the circumstances where the benefit from its use is maximal.
Objectives: This review aims to assess the value of chest ultrasonography in Respiratory Intensive Care Unit (R.I.C.U).
Data Sources: Medline databases (PubMed, Medscape, Science Direct) and all materials available in the internet till 2017.
Conclusions: Ultrasonography is an easily learned procedure that not only enhances the physical examination but also has the distinct advantages of being a portable tool that can provide real-time evaluation of the lung and pleural space, Its use has been associated with an improved yield and reduced complication rate for diagnosis and management of chest diseases, also it is quickly becoming the standard for procedural guidance.
As Intensivest physicians, we need to embrace ultrasounds broad clinical applications in chest diseases especially in R.I.C.U, with advantages of ultrasonography over plain chest radiography and CT that include the absence of radiation and the ability to perform dynamic evaluations.
