During critical illness the gut does not pass the acid test
Critical Care (London, England)
|September 26, 2012
Summary
Fecal pH can predict patient outcomes during critical illness. This simple measurement reflects the health of the gut microbiota, which is often disrupted in critically ill patients.
Area of Science:
- Gastroenterology
- Microbiology
- Critical Care Medicine
Background:
- Intestinal microflora plays a crucial role in health and disease.
- Critical illness disrupts the gut microbiota, leading to pathogenic species overgrowth.
- Antibiotic use and physiological stress contribute to microbiota dysbiosis.
Purpose of the Study:
- To evaluate fecal pH as a predictive marker for patient outcomes in critical illness.
- To assess the relationship between fecal pH and the functional output of the intestinal microflora.
Main Methods:
- Utilized fecal pH as a surrogate marker.
- Analyzed the predictive value of fecal pH in critically ill patients.
Main Results:
- Fecal pH demonstrated high predictive value for patient outcomes.
- Fecal pH may indicate the production of key organic acids by gut microflora.
Conclusions:
- Fecal pH is a valuable, non-invasive tool for assessing gut microbiota function in critical illness.
- Monitoring fecal pH could aid in predicting outcomes and managing critically ill patients.

01:27Microbiota of the Stomach and Small Intestine
The human gastrointestinal (GI) tract is characterized by distinct physicochemical conditions that shape its microbial communities. Among these, the stomach presents a particularly challenging environment for microbial colonization due to its highly acidic pH, ranging from 1 to 3. This extreme acidity effectively limits microbial density. However, certain acid-tolerant microorganisms are capable of surviving in this niche. Notably, Helicobacter pylori can colonize the gastric mucosa,...
01:07Intestinal Obstruction II: Pathophysiology
Intestinal obstruction triggers a series of physiological responses, starting with gas and fluid accumulation in the bowel segment proximal to the obstruction, leading to distension. This distended intestine compresses the diaphragm, hindering lung expansion and potentially leading to reduced respiratory effort, atelectasis, and pneumonia.To overcome the blockage, the gut intensifies contractions, causing colicky abdominal pain, nausea, and vomiting, which reduces fluid and food intake and...
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.
01:26Gastritis II: Pathophysiology
The pathophysiology of gastritis begins with the colonization of the stomach lining by Helicobacter pylori (H. pylori). This bacterium spreads mainly via the oral-oral route through saliva or shared utensils, and can also be transmitted in overcrowded or unhygienic environments through contaminated water, despite its brief survival outside the body.ColonizationOnce ingested, H. pylori enters the stomach and begins colonization by navigating through the mucus layer lining the stomach wall. It...
01:24Diagnosing Acidosis and Alkalosis
Diagnosing acid-base imbalances involves systematically analyzing arterial blood samples, focusing on three key measurements: pH, bicarbonate (HCO3−) concentration, and carbon dioxide partial pressure (PCO2). This analysis follows a four-step process that helps identify the imbalance's underlying cause and nature.
First, the pH level is assessed to determine whether the blood pH is normal (7.35–7.45), low (acidosis), or high (alkalosis).
Next, the PCO2 and HCO3− values are examined to...

01:17Gastritis-II: Pathophysiology
Gastritis is marked by disruption of the mucosal barrier that usually protects the stomach tissue from digestive juices and manifests in acute and chronic forms.
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...
