Summary
Systemic inflammation in intensive care units can cause liver microcirculation failure. Ketamine, midazolam, and fentanyl show promise for managing sedation in these patients due to potential anti-inflammatory effects.
Area of Science:
- Physiology
- Pharmacology
Context:
- Over 50% of intensive care unit patients develop systemic inflammation, including systemic inflammatory response syndrome (SIRS) and sepsis.
- Systemic inflammation can lead to hepatic microcirculatory failure and subsequent organ damage.
- Liver microcirculation is intricately regulated by cellular components and mediators, including Ito cells, nitric oxide (NO), carbon monoxide (CO), and endothelin.
Purpose:
- To review the regulation of hepatic microcirculation during systemic inflammation.
- To explore the impact of sedatives and analgesics on liver microcirculation in sepsis and SIRS.
- To identify potentially suitable sedatives for patients with systemic inflammation.
Summary:
- Hepatic microcirculation, crucial for liver function, is impaired during systemic inflammation.
- Vasoactive mediators like NO, CO, and endothelin modulate Ito cell tone, affecting sinusoidal perfusion.
- While definitive recommendations are pending, ketamine, midazolam, and fentanyl are suggested for sedation due to potential anti-inflammatory properties.
Impact:
- Highlights the critical role of hepatic microcirculation in critical illness.
- Informs potential therapeutic strategies for managing sedation in inflammatory conditions.
- Underscores the need for further research into optimal sedative choices for sepsis and SIRS patients.

01:24Liver Regeneration
The liver is an important organ in vertebrates that plays an essential role in metabolism. It is also responsible for storing and redistributing nutrients such as carbohydrates, fats, and vitamins in the body. Additionally, the liver releases bile salts which are critical for digesting food and eliminating toxic metabolites from the body.

01:26Effect of Hepatic Disease on Pharmacokinetics: Drug Dosing and Hepatic Blood Flow
Chronic liver disease significantly impacts drug metabolism due to alterations in hepatic blood flow and enzyme accessibility. This disruption affects the body's pharmacokinetics—the movement and processing of drugs within the system. Key enzymes crucial for metabolizing medications become less accessible, changing how drugs are processed and utilized. Furthermore, liver disease influences the synthesis of plasma proteins, such as albumin and globulins, which play critical roles in drug binding...
01:22Effect of Hepatic Disease on Pharmacokinetics: Pathophysiologic Assessment and Liver Function Test
In clinical practice, the direct measurement of hepatic blood flow to evaluate liver function presents significant challenges due to the intricate and specialized nature of the necessary techniques. Consequently, healthcare professionals often rely on empirical estimates derived from thorough patient examinations and liver function tests to gauge liver health. Among the tools at their disposal, the Child–Pugh and MELD scoring systems stand out for their ability to categorize and assess the...
01:25Acute Inflammation III: Local and Systemic Effects
Acute inflammation produces a coordinated set of local and systemic changes that limit injury, eliminate pathogens, and initiate repair. These responses arise within minutes of infection, trauma, or chemical insult and are driven by vascular alterations and leukocyte-derived mediators. When the stimulus resolves, the reaction typically abates within days.Local EffectsAt the site of injury, arteriolar vasodilation increases blood flow, resulting in redness and warmth. Simultaneously, increased...
01:12Chronic Inflammation: Introduction
Chronic inflammation is a prolonged, dysregulated immune response that persists for weeks to years when the inciting stimulus is difficult to eradicate or when self‑antigens drive ongoing reactivity. Morphologically, it is defined by mononuclear cell infiltration, progressive tissue destruction, and concurrent attempts at healing via angiogenesis and fibrosis. Compared with acute inflammation, edema is less prominent while cellular infiltration predominates; triggers include persistent...
01:24Cirrhosis II: Pathophysiology
Cirrhosis is a progressive chronic liver injury caused by prolonged inflammation, excessive fibrotic remodeling, and impaired regeneration. Over time, repeated hepatic insults disrupt the liver’s architecture and function, leading to reduced blood flow, impaired bile drainage, and diminished metabolic capacity.Pathophysiology of cirrhosisCirrhosis arises from three main responses to chronic liver damage: inflammation, immune activation, and hepatocyte death. These processes lead to structural...
