Antithrombin III Prevents Early Bacterial Translocation in Burn Injury
Annals of Burns and Fire Disasters
|October 13, 2011
Summary
Antithrombin III (AT III) significantly reduced bacterial translocation and intestinal damage in early burn injury. This study in rats shows AT III offers protection against post-burn complications, highlighting its therapeutic potential.
Area of Science:
- Biomedical research
- Surgical research
- Gastroenterology
Background:
- Burn injuries can lead to bacterial translocation (BT) and intestinal damage.
- Early intervention is crucial for managing post-burn complications.
Purpose of the Study:
- To investigate the effect of antithrombin III (AT III) on bacterial translocation and intestinal morphology in the early stages of burn injury.
- To evaluate AT III as a potential therapeutic agent for burn-induced gastrointestinal complications.
Main Methods:
- A rat model of full-thickness burn injury (30% total body surface area) was established.
- Groups included sham burn, burn injury, and burn injury with AT III treatment (250 U/kg).
- Bacterial translocation was assessed via cultures, and intestinal morphology was evaluated histopathologically.
Main Results:
- Burn injury significantly increased bacterial translocation (70% vs 10% in sham).
- AT III treatment markedly reduced bacterial translocation (10%) and villus degeneration (30% vs 90% in burn group).
- While AT III reduced neutrophil infiltration, the decrease was not statistically significant compared to the burn group.
Conclusions:
- Burn injury enhances bacterial translocation and causes intestinal mucosal damage.
- AT III administration effectively mitigates bacterial translocation and protects intestinal morphology in the early post-burn period.
- AT III demonstrates therapeutic potential for preventing intestinal injury and bacterial translocation following burns.

Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...

Infective endocarditis management involves a multifaceted approach encompassing infection prevention, lifestyle modifications, pharmacological therapy, and surgical management.Infection Prevention:Hand Hygiene: Thorough handwashing is crucial to prevent the spread of infection. Hand hygiene should be performed regularly, especially before and after using the restroom.Oral Hygiene: Good oral hygiene is essential. It includes brushing teeth immediately after waking up and before bed, flossing...
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...

Hemostasis is a crucial process that prevents excessive blood loss from damaged blood vessels. It involves various mechanisms such as vasoconstriction, platelet adhesion and activation, and fibrin formation. The importance of each mechanism depends on the type of vessel injury. In contrast, thrombosis is the abnormal formation of a blood clot within the blood vessels, leading to potential complications if the clot obstructs blood flow. Thrombosis can be caused by increased coagulability of the...

A pulmonary embolism occurs when a thrombus, amniotic fluid, tumor tissue, fat, or air embolus blocks one or more pulmonary arteries. Effective nursing management and patient education are crucial for improving outcomes and preventing recurrence.Nursing management starts with obtaining a comprehensive patient history, particularly noting any history of deep vein thrombosis (DVT). Assess for clinical manifestations, including dyspnea, chest pain, crackles, heart murmurs, and signs of right-sided...

Venous thrombosis, the most common disorder of the veins, involves the formation of a thrombus or blood clot associated with vein inflammation. It can be classified as either superficial vein thrombosis or deep vein thrombosis.Superficial Vein Thrombosis: This involves the formation of a thrombus in a superficial vein, usually the greater or lesser saphenous vein. Though less severe than deep vein thrombosis (DVT), SVT can lead to complications if untreated.Deep Vein Thrombosis (DVT): This...
