Intensive care medicine, often known as critical care medicine, is a medical specialty that treats seriously or critically ill patients who are suffering from, are at danger of, or are recovering from life-threatening diseases. Life support, invasive monitoring procedures, resuscitation, and end-of-life care are all part of it. Intensive care physicians, critical care physicians, and intensivists are all terms used to describe doctors who specialize in this field.
Intensive care relies on interdisciplinary teams made up of a variety of medical specialists. Doctors, nurses, physical therapists, respiratory therapists, and pharmacists are often members of such teams. They generally collaborate in hospital critical care units or Intensive Care Units (ICUs).
If a patient's medical requirements are more than what a standard hospital ward can give, they are admitted to the critical care unit. Blood pressure support for cardiovascular instability (hypertension/hypotension), sepsis, post-cardiac arrest syndrome, or specific cardiac arrhythmias are all indications for the ICU. Due to respiratory impairment, other ICU requirements include airway or ventilator assistance. The cumulative consequences of multiple organ failure, also known as multiple organ dysfunction syndromes, necessitate sophisticated medical attention. After such operation, patients may be brought to the ICU for careful monitoring or acute requirements.
Closed and open ICUs are the two most frequent ICU structures. In a closed unit, the intensivist is the primary caretaker for all of the patients. Each patient's primary physician, who may or may not be an intensivist, might vary in an open ICU. Closed units have a growing body of data showing they improve patient outcomes. The way patients are managed in critical care varies by country. In the United States, open units are the most prevalent arrangement, while closed units are popular in big academic centers. There are also intermediate structures that occur between open and closed units.
Intensive care units exist in a variety of forms; Intensive care is often administered in a hospital's specialist Intensive Care Unit (ICU) or Critical Care Unit (CCU). Many hospitals also offer dedicated critical care units for certain medical specialties. The nomenclature of units is not strictly standardized, and the sorts of units are determined by the requirements and resources available at each hospital. Here are a few of them:
• For heart illness, a Coronary Intensive Care Unit (CCU or CICU)
• Medical Critical Care Unit (MICU)
• Surgical Intensive Care Unit for surgeons (SICU)
• Pediatric Intensive Care Unit for children (PICU)
• Neuroscience Critical Care Unit for neurology (NCCU)
• Intensive-Recovery-Overnight (OIR)
• Intensive-Care Unit for Shock and Trauma (STICU)
• ICU in the Emergency department (E-ICU)
• Neonatal Intensive Care Unit (NICU)
Medical research reveals a connection between ICU volume and mechanically ventilated patients quality of treatment. Higher ICU volume was substantially related with reduced ICU and hospital death rates after adjusting for severity of illness, demographic covariates, and ICU features. In hospitals with 87 to 150 mechanically ventilated patients yearly, adjusted ICU mortality was 21.2% and 14.5 % in hospitals with 401 to 617 mechanically ventilated patients annually.
Hospitals with a moderate number of patients had results that were distance between these two extremes. ICU delirium, historically and incorrectly referred to as ICU psychosis, is a phenomenon that occurs in critical care and cardiac units when patients experience delirium as a result of being in strange, monotonous conditions. This might involve interpreting mechanical noises for human voices, seeing walls shake, or having the sensation of someone tapping them on the shoulder. There have been systematic evaluations that show that sleep promotion-related therapies in the ICU have a positive influence on the overall health of ICU patients.
The term "monitoring" refers to the use of a variety of instruments and technology to collect information on a patient's status. These can include tests to measure the function of organs like the heart and lungs, as well as blood flow and gas exchange throughout the body. In the ICU, there are two forms of monitoring that are commonly used: Invasive and non-invasive techniques.
Noninvasive monitoring does not require rupturing the skin and is typically painless. These tools are less costly, easier to use, and produce faster results. Invasive monitoring provides more accurate measurements, but it may include samples of blood or skin punctures, which can be painful or uncomfortable.
