Summary
Selective digestive decontamination (SDD) reduces infections and mortality in intensive care units (ICUs). Treating 5 ICU patients with SDD prevents pneumonia, and 12 prevent a death, with strong evidence supporting its use.
Area of Science:
- Critical care medicine
- Infectious disease prevention
- Microbiology
Context:
- Intensive care units (ICUs) face high rates of infection, particularly ventilator-associated pneumonia.
- Selective digestive decontamination (SDD) aims to prevent infections by targeting pathogenic microorganisms in the digestive tract.
- SDD is a prophylactic strategy for critically ill patients requiring intensive care.
Purpose:
- To review the efficacy and adverse effects of Selective Digestive Decontamination (SDD).
- To analyze evidence supporting SDD in reducing infections and mortality in intensive care.
- To discuss expert opinions regarding the use of SDD despite its recognized benefits.
Summary:
- Fifty-four randomized clinical trials (RCTs) and 9 meta-analyses evaluated SDD.
- Thirty-eight RCTs and all meta-analyses show significant infection reduction; 4 RCTs and 5 meta-analyses report reduced mortality.
- Evidence for SDD's mortality benefit is Grade 1/Recommendation A, requiring treatment of 5 ICU patients for pneumonia prevention and 12 for mortality prevention.
Impact:
- SDD is recognized as a highly effective intervention for reducing morbidity and mortality from infections in intensive care settings.
- Strong evidence supports SDD in preventing ventilator-associated pneumonia and reducing overall mortality.
- Further discussion is needed on expert concerns despite SDD's proven benefits in critical care infections.

01:50What is Monogastric Digestion?
The human body contains a monogastric digestive system. In a monogastric digestive system, the stomach only contains one chamber in which it digests food. Several other animal species also have monogastric digestive systems, including pigs, horses, dogs, and birds. This chapter, however, focuses on the human digestive system.
01:14Prevention of Further Absorption of Poison
In cases of acute poisoning, the primary objective is to prevent further absorption of the toxic substance into the body. Immediate interventions using various decontamination techniques targeting the gastrointestinal (GI) tract can achieve this. Decontamination is crucial to prevent poison from entering the systemic circulation, which involves washing affected areas with water and mild soap and removing contaminated clothing. Once external decontamination is done, attention must be turned to...
01:26Enhanced Elimination of Poison
Poison can be effectively removed from the gastrointestinal (GI) tract through various decontamination procedures.
Antidotes serve a crucial role in counteracting the effects of poison by inhibiting enzymes responsible for producing harmful drug metabolites. In some cases, these toxic metabolites can be neutralized by endogenous cosubstrates, which are maintained at specific concentrations to prevent interaction with cellular macromolecules and subsequent cell death.

01:26Pharmaceutical Poisoning: Treatment Strategies
Treatment strategies for poisoning are a critical aspect of emergency medicine, focusing on preventing the absorption of toxins and enhancing their elimination. When a poisoning incident occurs, the first response is to halt exposure and decontaminate the patient, particularly through gastrointestinal (GI) methods if the poison was ingested.Gastrointestinal Decontamination Techniques:Activated charcoal is the cornerstone of GI decontamination. It works through adsorption, binding the toxin to...
01:30Cleaning, Sterilization, and Disinfection
Cleaning, disinfection, and sterilization are the methods that help to break the infection chain and prevent disease.
Cleaning
The cleaning process usually involves using water with detergents or enzymatic cleaner and removing foreign material from objects and surfaces, including organic material such as body fluids or inorganic material like soil. Cleaning is performed before high-level disinfection and sterilization because foreign materials on the cover of the devices interfere with process...
