Insights

Probiotics supplementation significantly improved postprandial intestinal blood flow velocity in extremely low birth weight neonates. This finding suggests a beneficial effect of probiotics on gut circulation in this vulnerable population.

Area of Science:

  • Neonatal Medicine
  • Gastroenterology
  • Microbiology

Background:

  • Extremely low birth weight (ELBW) neonates are at high risk for gastrointestinal complications.
  • Intestinal blood flow is crucial for gut health and function in neonates.

Purpose of the Study:

  • To investigate the effect of probiotics supplementation on intestinal blood flow velocity in ELBW neonates.
  • To determine if probiotics enhance postprandial intestinal perfusion.

Main Methods:

  • Randomized, double-blind, placebo-controlled trial involving ELBW neonates.
  • Probiotics administered with enteral feeding until discharge or 34 weeks postmenstrual age.
  • Pulsed Doppler used to measure time-averaged mean velocity (TAMV), peak systolic velocity (PSV), and end diastolic velocity (EDV) preprandially and postprandially.

Main Results:

  • A total of 31 infants (15 probiotics, 16 placebo) were analyzed.
  • Significant postprandial increase in TAMV observed in the probiotic group compared to placebo (P=0.035).
  • Trends towards increased PSV and EDV in the probiotic group.

Conclusions:

  • Probiotics administration significantly enhances postprandial intestinal blood flow in ELBW preterm neonates.
  • Findings suggest a positive impact of probiotics on intestinal hemodynamics in this population.

Blood Flow01:29

Blood Flow

Blood is pumped by the heart into the aorta, the largest artery in the body, and then into increasingly smaller arteries, arterioles, and capillaries. The velocity of blood flow decreases with increased cross-sectional blood vessel area. As blood returns to the heart through venules and veins, its velocity increases. The movement of blood is encouraged by smooth muscle in the vessel walls, the movement of skeletal muscle surrounding the vessels, and one-way valves that prevent backflow.
Development of Human Microbiota01:30

Development of Human Microbiota

The human microbiota begins developing at birth and undergoes continual change as we age. Infancy marks a critical period of microbial sensitivity, offering a “window of opportunity” during which beneficial microbes help mature the immune system. By age three, children typically develop a more stable and diverse microbial community. Newborns acquire microbes from their immediate environment; vaginal delivery favors maternal vaginal microbes, while cesarean births favor microbes from the skin...
Anatomy of the Intestines01:23

Anatomy of the Intestines

Although digestion of proteins, carbohydrates, and lipids may begin in the stomach, it is completed in the intestine. The absorption of nutrients, water, and electrolytes from food and drink also occurs in the intestine. The intestines can be divided into two structurally distinct organs—the small and large intestines.
Small Intestines
The small intestine is an ~7 meter-long tube with an inner diameter of just 2.5 cm. Since most nutrients are absorbed here, the inner lining of the small...

Pharmacokinetics in Pediatric Patients: Overview and Drug Absorption

Understanding the physiological differences in the pediatric population is crucial for effective pharmacotherapy. Neonates, infants, and children exhibit significant variations in gastric pH, gastric emptying time, intestinal transit time, and biliary function. These variations profoundly affect oral drug absorption, necessitating a nuanced approach to pediatric dosing.Neonates present with a unique physiological profile, having a gastric pH greater than 4 and faster and more irregular gastric...
Probiotics01:22

Probiotics

Probiotics are live, non-pathogenic microorganisms that confer health benefits by modulating the gut microbiota. The human gastrointestinal tract harbors a complex microbial ecosystem, and the balance of this microbiota is crucial for digestive and systemic health. Among the most extensively studied and utilized probiotics are species formerly classified within the genera Lactobacillus and Bifidobacterium. These organisms not only naturally colonize the human gut but are also consumed through...
Blood Supply to the Digestive System01:16

Blood Supply to the Digestive System

Splanchnic circulation refers to the network of blood vessels that supply and drain blood from the abdominal organs involved in digestion, including the stomach, liver, pancreas, intestines, and spleen. This circulation delivers essential nutrients and oxygen while removing waste products from these organs.
Blood Supply to the Digestive System: The splanchnic circulation involves three main arteries: the celiac artery (also known as the celiac trunk) and the superior and inferior mesenteric...
