Acute Inflammation III: Local and Systemic Effects

Acute 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...

Acute Inflammation I: Inflammatory Response

Acute Inflammation I: Inflammatory Response

Acute inflammation is a rapid, short-lived physiological response to tissue injury or infection, designed to eliminate harmful agents and initiate repair. This tightly regulated process typically lasts from minutes to several days and is triggered by factors such as microbial invasion, physical trauma, or chemical injury.Recognition and Mediator ReleaseThe inflammatory response begins when resident immune cells—such as mast cells, macrophages, and dendritic cells—detect damage-associated...

Inflammatory Response

Inflammatory Response

An inflammatory response is a localized, nonspecific immune reaction that occurs when a tissue is injured. It is characterized by redness, swelling, heat, and pain, which are commonly called the cardinal signs and symptoms of inflammation. Inflammation can sometimes result in a loss of function.
Inflammation can be triggered by various stimuli, such as impact, abrasion, chemical irritation, infections, and extreme hot or cold temperatures. These can damage cells and connective tissue fibers,...

Appendicitis-II: Diagnostic Studies and Management

Appendicitis-II: Diagnostic Studies and Management

Diagnosing and managing appendicitis requires a structured and comprehensive approach that spans from initial assessment to postoperative care. Here is an overview of the process:
Diagnosing Appendicitis
It requires a multifaceted approach, starting with a detailed physical examination to pinpoint the location and nature of the pain and identify any associated symptoms. Laboratory tests play a crucial role. A complete Blood Count (CBC) typically reveals leukocytosis (an increased number of...

Complement System

Complement System

The complement system is a group of approximately 20 plasma proteins that strengthen the body's defenses against infections through opsonization, inflammation, and cell lysis. Opsonization involves coating pathogens with complement proteins, making them more recognizable and facilitating phagocyte engulfment. Certain complement proteins induce inflammation that attracts immune cells to the site of infection. Cell lysis involves the destruction of pathogens through the formation of a membrane...

Summary

This summary is machine-generated.

Major abdominal surgery activates the complement system and releases interleukins. Both total intravenous anaesthesia (TIVA) and inhalational anaesthesia resulted in similar complement activation and cytokine release during colorectal surgery.

Area of Science:

Surgical oncology
Anesthesiology
Immunology

Background:

Major abdominal surgery, particularly colorectal procedures, can trigger systemic inflammatory responses.
The role of anesthesia type in modulating these responses remains an area of investigation.

Purpose of the Study:

To investigate complement activation and interleukin release following major abdominal surgery.
To compare the effects of total intravenous anaesthesia (TIVA) versus inhalational anaesthesia on these inflammatory markers.

Main Methods:

Prospective, randomized study of 50 patients undergoing open major colorectal surgery.
Patients received either TIVA (propofol/remifentanil) or inhalational anaesthesia (sevoflurane/fentanyl).
Blood samples analyzed for complement activation (C3a, SC5b-9) and cytokines (TNF-a, IL-1b, IL-6, IL-8, IL-4, IL-10) preoperatively and at multiple postoperative time points.

Main Results:

Major colorectal surgery led to complement activation and release of pro-inflammatory (IL-6, IL-8) and anti-inflammatory (IL-10) interleukins.
No significant differences in complement activation or cytokine release were observed between TIVA and inhalational anaesthesia groups.

Conclusions:

Major colorectal surgery activates the complement cascade and modulates both pro- and anti-inflammatory cytokine profiles.
The choice between TIVA and inhalational anaesthesia did not significantly impact complement activation or interleukin release in this study.
