Insights

Newborns with ankyloglossia (tongue-tie) exhibit longer suction bursts during feeding. This objective measurement may help evaluate infant feeding difficulties and breastfeeding pain.

Area of Science:

  • Pediatric Medicine
  • Neonatology
  • Biomedical Engineering

Background:

  • Ankyloglossia, commonly known as tongue-tie, can affect infant feeding.
  • Objective methods are needed to quantify infant suction patterns.
  • Previous studies have not objectively measured suction in infants with ankyloglossia.

Purpose of the Study:

  • To compare infant suction patterns in babies with and without ankyloglossia.
  • To utilize a microprocessor-controlled pressure sensor for objective suction measurement.
  • To evaluate the utility of this method in assessing ankyloglossia.

Main Methods:

  • Fifty-five infants (0-2 months) were clinically assessed for ankyloglossia.
  • A silicone pacifier connected to a pressure sensor recorded suction activity.
  • Key parameters analyzed included burst duration, suck frequency, and inter-burst interval.

Main Results:

  • Infants with ankyloglossia demonstrated significantly longer bursts of suction activity compared to controls.
  • No other significant differences in suction parameters were noted between groups.
  • Longer burst durations suggest a potential compensatory mechanism.

Conclusions:

  • Longer suction burst durations in ankyloglossia may be a compensatory strategy.
  • These feeding pattern differences could contribute to breastfeeding pain reported by mothers.
  • The developed method offers objective quantification of infant suction capacity for ankyloglossia evaluation.

Suctioning the Nasopharyngeal Airway01:29

Suctioning the Nasopharyngeal Airway

Nasopharyngeal suctioning is a procedure to remove secretions from the upper part of the respiratory tract that the patient cannot clear independently. It helps maintain airway patency and prevents complications such as aspiration pneumonia.

Suctioning the Oropharyngeal Airway

In preparing for oropharyngeal airway suctioning, a nurse must gather all necessary equipment, including a suction unit with tubing, a prepackaged suction kit, sterile gloves, water or saline for irrigation, a water-soluble lubricant, and additional personal protective equipment (such as a gown, mask, and goggles) to control infections.
After assembling the equipment, the nurse should practice hand hygiene and don appropriate PPE according to infection control guidelines to avoid the...

Tracheostomy Suctioning II: Procedure

Tracheostomy suctioning is a vital nursing procedure that involves removing secretions from the tracheostomy tube to maintain airway patency and prevent respiratory complications. Nurses need to understand the proper technique for tracheostomy suctioning to ensure patient safety and comfort. In this guide, we will outline the step-by-step process for performing tracheostomy suctioning, including preparing the sterile field, donning personal protective equipment (PPE), lubricating and connecting...

Psychosexual Stages of Personality: Oral01:16

Psychosexual Stages of Personality: Oral

The oral stage is the initial phase of Sigmund Freud's theory of psychosexual development, occurring from birth to approximately 12 to 18 months. During this period, the infant's mouth serves as the primary source of pleasure, with actions such as sucking, chewing, biting, and drinking playing a crucial role in reducing tension. These activities are essential not only for nourishment but also for the infant's psychological and emotional satisfaction.

Breathing01:05

Breathing

The process of breathing, inhaling and exhaling, involves the coordinated movement of the chest wall, the lungs, and the muscles that move them. Two muscle groups with important roles in breathing are the diaphragm, located directly below the lungs, and the intercostal muscles, which lie between the ribs. When the diaphragm contracts, it moves downward, increasing the volume of the thoracic cavity and creating more room for the lungs to expand. When the intercostal muscles contract, the ribs...

Tracheostomy Suctioning I: Pre-Procedural Steps

Tracheostomy suctioning is a critical procedure healthcare professionals perform to maintain a patent airway in patients with a tracheostomy tube. This procedure is necessary when secretions accumulate in the airway, causing respiratory distress. Here is a step-wise procedural guide for performing tracheostomy suctioning using an open system.
Equipment Required
First, gather all necessary equipment: a sterile suction catheter, a sterile disposable container, sterile gloves, a towel or...
