Insights

Expiratory flow increase technique (EFIT) does not worsen acid reflux in preterm infants with bronchopulmonary dysplasia (BPD). Studies show EFIT, when used 2-3 hours post-feeding, is safe for managing BPD in these vulnerable infants.

Area of Science:

  • Pediatrics
  • Neonatology
  • Respiratory Medicine

Background:

  • Bronchopulmonary dysplasia (BPD) is a chronic lung disease common in preterm infants.
  • Acid reflux is a frequent complication in infants with BPD, potentially impacting respiratory outcomes.
  • The expiratory flow increase technique (EFIT) is used to aid airway clearance in infants with BPD.

Purpose of the Study:

  • To investigate the association between the expiratory flow increase technique (EFIT) and gastroesophageal acid reflux episodes.
  • To assess the safety of EFIT in preterm infants diagnosed with bronchopulmonary dysplasia (BPD).

Main Methods:

  • A randomized crossover study involving 18 preterm infants with BPD.
  • Infants were assigned to two groups, receiving EFIT sessions at 2 or 3 hours postprandial.
  • Esophageal pH monitoring assessed the reflux index (RI) before and during EFIT.

Main Results:

  • A significant reduction in the reflux index (RI) was observed when EFIT was performed 2 hours after feeding (Group 1).
  • No significant difference in RI was found before and during EFIT in infants tested 3 hours after feeding (Group 2).
  • EFIT was not associated with an increase in acid reflux episodes in either group.

Conclusions:

  • The expiratory flow increase technique (EFIT) is not associated with an increase in acid reflux episodes.
  • Performing EFIT 2 to 3 hours after feeding appears safe for preterm infants with BPD regarding acid reflux.

Pulmonary Cycle: Exhalation01:17

Pulmonary Cycle: Exhalation

In terms of human respiration, the act of expelling air, known as exhalation (or expiration), operates on the principle of pressure gradients. During expiration, the pressure within the lungs exceeds that of the surrounding atmosphere. Under normal conditions, quiet breathing involves passive exhalation and is free of muscular contractions. This is because the exhalation process is driven by the natural elastic recoil of the lungs and chest wall, both of which have an inherent tendency to...

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...

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...
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,...
Acute Respiratory Failure-V01:29

Acute Respiratory Failure-V

The treatment for acute respiratory failure varies based on factors like the underlying cause, overall health, and severity. A collaborative healthcare team is essential for early detection, often through arterial blood gas analysis. Identifying the cause is the primary goal, with treatment strategies adjusted for ventilation/perfusion (V/Q) mismatch, shunting, or diffusion impairment.
Ensure that patients are monitored continuously for their response to therapy, including changes in...

Endoscopic Studies II: Thoracocentesis

Thoracentesis(Thoracocentesis), commonly known as pleural tap, is a medical procedure where a 22 gauge needle is inserted into the pleural space, the area between the lung and chest wall. This procedure is commonly performed to diagnose or treat various respiratory disorders.
Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...
