Gastrointestinal system
(CRC Press, 2023) Ashish Verma; Sakshi Duggal; Ishan Kumar
Abdominal imaging is commonly performed in the intensive care unit (ICU) in patients with abdominal obstruction, perforation, blunt trauma, bleeding etc. for confirming clinical diagnosis. It is also performed in postoperative patients, after intervention procedures, liver and gall bladder diseases, pancreatitis and suspected poisoning. Among the imaging procedures, USG and plain X-ray can be performed at the bedside while other procedures may require patient transfer to the radiology suite. The findings from USG and X-ray may get obtunded by bowel gas, wounds, catheters, edema etc. The intensivist should know the indications for different procedures and choose the right imaging after weighing the risk-benefit ratio. The chapter highlights the techniques for interpreting the findings after all types of abdominal imaging. © 2024 selection and editorial matter, Anirban Hom Choudhuri and Ashish Verma; individual chapters, the contributors.
Respiratory system
(CRC Press, 2023) Ashish Verma; Bhuvna Ahuja; Sakshi Duggal; Ishan Kumar
Critically ill patients undergo various respiratory imaging while in the ICU. Most of the patients undergo chest X-ray. This is useful to detect lung consolidation, collapse and effusion. It also helps detection of pneumothorax, cavitations and ARDS. Additional information can be obtained from bedside USG of the lung. Besides diagnosis, USG can aid bedside percutaneous dilatational tracheostomy and chest tube drainage. Patients with non-resolving ARDS also undergo chest CT, which also rules out malignancies. CT angiography is also essential for pulmonary embolism. The role of individual imaging modalities, their techniques and interpretation have been outlined in this chapter. © 2024 selection and editorial matter, Anirban Hom Choudhuri and Ashish Verma; individual chapters, the contributors.
