Less invasive surfactant administration methods: Who, what and how
1Department of Pediatrics, Division of Neonatology, Vanderbilt University School of Medicine, Nashville, TN, USA.
Summary
New methods deliver surfactant without endotracheal tubes (ETT) for respiratory distress syndrome. These techniques, including thin catheter and laryngeal airway methods, offer alternatives to traditional ETT surfactant administration in neonatal intensive care units (NICUs).
Area of Science:
- Neonatal Medicine
- Respiratory Physiology
- Medical Device Technology
Background:
- Endotracheal tube (ETT) surfactant administration is standard for infant respiratory distress syndrome.
- Non-invasive ventilation is increasingly used in neonatal intensive care units (NICUs).
- This necessitates alternative surfactant delivery methods avoiding ETTs.
Purpose of the Study:
- To review non-ETT surfactant administration techniques.
- To discuss clinical implementation considerations for these methods.
- To provide an overview of emerging surfactant delivery strategies.
Main Methods:
- Literature review of surfactant administration techniques.
- Description of minimally invasive surfactant administration (MIST) and laryngeal mask airway (LMA) methods.
- Discussion of aerosolization and supraglottic airway (SALSA) approaches.
Main Results:
- Several ETT-free surfactant delivery methods exist.
- Techniques include thin catheter (LISA, MIST), aerosolization, and LMA/SALSA.
- These methods aim to reduce invasiveness and improve outcomes.
Conclusions:
- Non-ETT surfactant administration is evolving.
- Clinical adoption requires careful consideration of technique and patient factors.
- These advancements offer promising alternatives for neonatal respiratory support.

01:18Additional Routes of Drug Administration

Choosing the appropriate route of drug administration is significantly influenced by two key factors: the therapeutic objectives and the inherent properties of the drug being used.
Administering drugs via inhalation allows for the direct delivery of gaseous, volatile substances or droplets to different parts of the respiratory tract. One of the advantages of the inhalation route is the rapid absorption of drugs into the circulatory system, which is possible because of the large surface area of...

302
Inhaled medications are crucial for managing chronic obstructive pulmonary disease (COPD) and asthma. They are essential for effective treatment and control, ensuring optimal respiratory health and well-being. Inhaled medication delivers drugs directly to the lungs, providing a rapid onset of action and reducing systemic side effects compared to oral or injectable medications. Three primary types of inhalation devices are used to administer these medications: nebulizers, metered-dose inhalers...

Drug delivery methods like oral inhalation, nasal sprays, transdermal patches, eye drops, intravitreal injection, and rectal administration provide localized effects with reduced toxicity.
Oral inhalation and nasal sprays swiftly transfer drugs across the respiratory epithelium's mucosal layer. Inhaled glucocorticoids and bronchodilators directly target lung conditions such as asthma, while fluticasone nasal spray mitigates allergic rhinitis.

59.5K
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...

Noninvasive positive-pressure ventilation (NIPPV), continuous positive airway pressure (CPAP), and bilevel positive airway pressure (BiPAP) are essential methods in respiratory care. These ventilation techniques offer unique benefits for patients with various respiratory conditions, providing adequate support without requiring intubation. Let's explore how each method is crucial in improving patient outcomes and enhancing respiratory therapy.

Mechanical ventilators are life-saving devices that support or replace spontaneous breathing. They deliver breaths to patients through varying methods known as ventilator modes. Understanding these modes is critical for healthcare providers managing patients with respiratory failure.
There are three ventilatory modes: full support, partial support, and spontaneous. These are described below.
Full Support Modes
Full support modes include controlled mechanical ventilation, continuous mandatory...
