Nipple position is believed to influence breastfeeding success. To investigate this belief, submental ultrasound images were obtained during breastfeeding of normal term infants. This study measured nipple to hard-soft palate distance (NHSPD) in 18 mother-infant pairs during the first and fourth weeks of life. Median NHSPD was 5 mm (interquartile: 4, 6 mm). There were no significant differences in median NHSPD between first, second, and fifth minutes of feeding (P = .675) or between week 1 and week 4 (P = .320). The nipple was not stationary during feeding, with mean nipple movement of 4.0 -/+ 1.3 mm. Further research is required with more infants to confirm the boundaries of normality for ultrasound measurements of nipple position during successful breastfeeding.

Ultrasound I: Abdominal Ultrasonography

Introduction:
Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...

Anatomical Positions

In anatomy, several standard anatomical positions are used as references for describing the position and orientation of different body parts. These positions help provide a common frame of reference when discussing anatomical structures. The anatomical position is the standard reference point for describing the body's position and orientation. In this position:
The body is upright, facing forward, and standing erect.
The feet are parallel and flat on the floor.
The arms are hanging by the...
Temperature Measurement Sites01:14

Temperature Measurement Sites

A thermometer measures body temperature. The common sites for measuring body temperature are the oral cavity, axillary region, temporal artery, and skin surface, such as the forehead, abdomen, and axilla. True core body temperature is assessed in the rectum, tympanic membrane, pulmonary artery, esophagus, and urinary bladder.
Oral: When assessing oral temperature, the thermometer tip should be placed under the tongue in the posterior sublingual pocket. It offers accurate readings and can be...
