Insights

Abdominal distension is a common concern in preterm infants receiving enteral nutrition. This study found that the abdominal circumference to weight ratio increases as infant weight decreases, which may be misinterpreted clinically.

Area of Science:

  • Neonatal Medicine
  • Pediatric Gastroenterology

Background:

  • Abdominal distension is a key clinical sign leading to feeding cessation in preterm infants.
  • Accurate assessment of abdominal circumference is crucial for monitoring infant health.

Purpose of the Study:

  • To establish reference values for abdominal circumference (AC) in preterm infants receiving full enteral nutrition.
  • To investigate the relationship between AC, infant weight, and the AC to weight ratio.

Main Methods:

  • Measurement of abdominal circumference in 42 preterm infants.
  • Analysis of AC in relation to infant weight during full enteral nutrition.

Main Results:

  • Abdominal circumference showed a linear decrease with decreasing infant weight (r² = 0.83).
  • The AC to weight ratio demonstrated a hyperbolic increase as infant weight decreased.

Conclusions:

  • The increasing AC to weight ratio in lower-weight preterm infants may be misidentified as pathological abdominal distension.
  • This finding has implications for the clinical assessment and management of feeding in preterm neonates.

z Scores and Area Under the Curve01:17

z Scores and Area Under the Curve

z scores are the standardized values obtained after converting a normal distribution into a standard normal distribution. A z score is measured in units of the standard deviation. The z score tells you how many standard deviations the value x is above (to the right of) or below (to the left of) the mean, μ. Values of x that are larger than the mean have positive z scores, and values of x that are smaller than the mean have negative z scores. If x equals the mean, then x has a z score of zero.

Assessment of the Abdomen I: Inspection and Auscultation

Introduction
The abdominal examination is a cornerstone of clinical medicine, serving as a critical tool in diagnosing various gastrointestinal (GI) diseases. It involves a systematic approach that includes inspection and auscultation, each with distinct yet complementary roles in assessing the abdomen. This article will delve into these two primary methods healthcare professionals use to examine the abdomen.
Inspection of the Abdomen
The first step in any abdominal examination is inspection.
Assessment of the Abdomen II: Percussion01:18

Assessment of the Abdomen II: Percussion

Percussion is a fundamental technique used to assess the liver, spleen, and abdominal organs by tapping the abdomen and interpreting the resulting sounds. This method helps identify fluid, distention, and masses through variations in sound, such as the high-pitched tympany of air-filled areas and the dullness of solid masses. Understanding how to percuss these organs provides valuable information for healthcare professionals in diagnosing conditions early.

Obesity01:24

Obesity

The Body Mass Index (BMI) is a numerical value derived from a person's weight and height, used to categorize individuals into weight ranges. It is calculated using the formula: weight in kilograms divided by height in meters squared. Obesity is a health condition characterized by excessive accumulation of adipose tissue that poses health risks, often diagnosed with a BMI ≥ 30. This excess fat storage occurs when surplus dietary calories are converted into triglycerides and stored in adipocytes...
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...
Abdominal Regions and Quadrants01:19

Abdominal Regions and Quadrants

To promote clear communication, for instance, about the location of a patient's abdominal pain or a suspicious mass, anatomists and clinicians typically use imaginary lines to categorize the abdominopelvic cavity into either four quadrants or nine regions to identify organs in the cavity.
The simpler quadrants approach, which is more commonly used in medicine, subdivides the cavity with one horizontal and one vertical line that intersects at the patient's umbilicus (navel). The four quadrants...
