Bedside echocardiography in critically ill patients

Understanding the principles and aims of intravenous fluid therapy

A balance between the volume of fluid taken in by the human body, and the volume of fluid excreted, is essential for life. Body fluid balance, which is maintained via various homeostatic mechanisms, can be disrupted by injury or disease. Prompt action is usually required to replenish fluid volumes and restore homeostasis, which is achieved via intravenous (IV) fluid therapy. Nurses will often encounter patients with a disrupted fluid balance, particularly in critical care. They will be involved in assessing patients' fluid status and administering and monitoring therapy. Therefore, nurses have an important role in ensuring the safety and effectiveness of IV fluid therapy. This article provides an overview of the principles and aims of IV fluid therapy. It also explains the physiology of body fluid and mechanisms of fluid balance regulation, outlines the principles of patient assessment and indications for IV fluid therapy, and details its potential risks and complications.

[Recommendations for education in ultrasound in medical intensive care and emergency medicine: position paper of DGIIN, DEGUM and DGK]

Point-of-care ultrasound in acute care medicine is a prerequisite for diagnosis and therapy monitoring of critically ill patients. There is currently no uniform education strategy for medical intensive care and emergency medicine. As part of the basic level, the trainee takes theoretical and clinical training covering abdominal and thoracic ultrasonography and focused cardiovascular ultrasound. In a second step, special knowledge and skills can be acquired at an expert level. This two-stage concept is intended to guarantee quality assurance in ultrasound education in medical intensive care and emergency medicine.
