Antiasthma Drugs: β2-Adrenoceptor Agonists01:25

Antiasthma Drugs: β2-Adrenoceptor Agonists

Bronchodilators are critical in managing asthma, a chronic respiratory condition characterized by airway constriction due to inflammation and hyper-reactivity. Specifically, bronchodilators ease this constriction by relaxing the bronchial muscles, facilitating easier breathing.
One class of bronchodilators includes β2-adrenoceptor agonists. These agents target the β2-adrenoceptors located on bronchial smooth muscle cells. By stimulating these receptors, β2-agonists induce relaxation in these...
Antiasthma Drugs: Muscarinic Receptor Antagonists01:20

Antiasthma Drugs: Muscarinic Receptor Antagonists

Muscarinic receptor antagonists, also known as antimuscarinic agents, are a class of bronchodilators used to treat asthma, although they are more commonly used to treat COPD. They work by inhibiting the action of acetylcholine (ACh), a neurotransmitter, on muscarinic receptors found in the airways.
Antimuscarinic agents compete with ACh for the same binding site on the muscarinic receptors. By binding to these receptors, they inhibit the downstream effects of ACh and block the parasympathetic...

COPD: Management Using Bronchodilators and Corticosteroids

Chronic obstructive pulmonary isease (COPD) involves a group of progressive lung disorders characterized by persistent airflow limitation and chronic respiratory symptoms. Asthma-COPD Overlap Syndrome (ACOS), encompassing features of both asthma and Chronic obstructive pulmonary disease (COPD), is a group of progressive lung disorders that includes chronic bronchitis, emphysema, and refractory (non-reversible) asthma. ACOS leads to complex clinical presentations that combine the inflammatory...

Asthma-IV: Diagnostic and Management

The diagnosis and management of asthma are comprehensive, encompassing clinical assessments, lung function tests, and pharmacological interventions. Here's an overview:

Inhaled Medications01:23

Inhaled Medications

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...

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...

Area of Science:

  • Pediatric Anesthesiology
  • Respiratory Medicine
  • Medical Device Technology

Background:

  • Previous methods for pediatric single lung ventilation have lacked consistency and reliability.
  • Effective single lung ventilation is crucial for specific pediatric surgical procedures.

Purpose of the Study:

  • To evaluate the efficacy and safety of the Arndt 5 French (Fr) paediatric endobronchial blocker for single lung ventilation in children.
  • To assess the ease and reliability of device placement and function.

Main Methods:

  • A series of 24 pediatric patients (aged 2-16 years) underwent single lung ventilation using the Arndt paediatric endobronchial blocker.
  • Procedure time for placement was recorded, and success rates were documented.

Main Results:

  • Successful single lung ventilation was achieved in 23 out of 24 patients.
  • Device placement took approximately 5-15 minutes.
  • Placement was aborted in one patient due to underlying lung pathology causing intolerance to apnea.

Conclusions:

  • The Arndt 5 French paediatric endobronchial blocker is a consistent and safe method for achieving single lung ventilation in most young children.
  • While the device has limitations, it represents a significant improvement over previously reported techniques.
