Insights

Gastroesophageal reflux (GER) does not appear to cause or prolong apnea in preterm infants. This study found no temporal link between GER and apnea, nor did it affect apnea duration or severity.

Area of Science:

  • Neonatal physiology
  • Pediatric gastroenterology
  • Respiratory control

Background:

  • Gastroesophageal reflux (GER) is common in preterm infants.
  • The relationship between GER and apnea, a frequent concern in neonates, requires further clarification.

Purpose of the Study:

  • To investigate the temporal association between GER and apnea in preterm infants.
  • To determine if GER influences the duration or severity of apnea.

Main Methods:

  • 119 preterm infants underwent 12-hour cardiorespiratory monitoring.
  • Respiratory inductance plethysmography, heart rate, SaO2, and esophageal pH were recorded.
  • GER and apnea events were scored and analyzed for temporal relationships and duration.

Main Results:

  • Over 6000 GER episodes were recorded, with only 1% associated with significant apnea.
  • No increase in apnea rate was observed before, during, or after GER.
  • GER did not prolong apnea duration or worsen associated drops in SaO2 or heart rate.

Conclusions:

  • No evidence supports a temporal relationship between acid reflux and apnea in preterm infants.
  • GER does not appear to prolong apnea or negatively impact cardiorespiratory parameters during apnea.

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...
Gastroesophageal Reflux Disease01:25

Gastroesophageal Reflux Disease

Gastroesophageal reflux disease (GERD) is the backward flow of stomach contents (acid, pepsin, or bile) into the esophagus, causing mucosal inflammation known as esophagitis. It results from failure of antireflux mechanisms, mainly the lower esophageal sphincter (LES), influenced by mechanical and physiological factors.Etiology and Risk FactorsGERD develops when LES function is weakened or when intra-abdominal pressure increases. Risk factors include aging, obesity, and sliding hiatal hernia,...

Respiratory Volumes and Capacities I

Assessing the respiratory rate and rhythm for a complete minute is crucial for evaluating the breathing pattern. Even a minor increase in the patient's average respiratory rate, by as little as three to five breaths per minute, is an early and vital indicator of respiratory distress. Patients with a respiratory rate exceeding twenty-four breaths per minute require close monitoring to determine the physiological alterations. This careful observation is essential for prompt recognition and...
Endotracheal Tube Extubation01:24

Endotracheal Tube Extubation

Endotracheal tube extubation is a critical procedure in weaning patients from mechanical ventilation. It involves physically removing the oral or nasal endotracheal (ET) tube, marking the final step in liberating a patient from ventilatory support.
Procedure
Extubation removes the endotracheal tube (ETT) from the patient on mechanical ventilation. It requires a well-coordinated, multidisciplinary approach involving physicians, nurses, respiratory therapists, and other healthcare professionals.

Cardiopulmonary Resuscitation II: ACLS Airway Management

Airway management is a key skill in emergency and critical care settings, as maintaining a clear airway is essential for adequate oxygenation and ventilation.Head Tilt-Chin Lift TechniqueThe head tilt-chin lift maneuver is an essential technique primarily used in patients without suspected cervical spine injuries. To perform this maneuver, one hand is placed on the patient’s forehead, and gentle pressure is applied backward to tilt the head. The fingertips of the other hand are positioned under...
Acute Respiratory Failure-IV01:23

Acute Respiratory Failure-IV

Respiratory failure can manifest suddenly or gradually, characterized by a rapid decline in PaO2 and a rapid rise in PaCO2. This situation indicates a severe respiratory problem that may quickly become a life-threatening emergency. One of the early signs of hypoxemic Acute Respiratory Failure (ARF) is a change in mental status due to the brain's sensitivity to oxygen levels and changes in acid-base balance. Symptoms such as restlessness, confusion, and agitation suggest inadequate oxygen...
