Topical Airway Anesthesia for Awake-endoscopic Intubation Using the Spray-as-you-go Technique with High Oxygen Flow

2017
The topical anesthetic lidocaine was atomized using a high oxygen flow through the working channel of a flexible intubating endoscope to achieve topical airway anesthesia for awake endotracheal intubation. We prefer this modified spray-as-you-go technique for endoscopic intubation to classical bolus application because of higher patient satisfaction and better compliance.

Cardiopulmonary Resuscitation V: Advanced Airway Management Techniques
0 Views •
2025
Airway management is essential in emergency and surgical medicine, ensuring ventilation and oxygenation in patients who cannot maintain their own airway. Clinicians use a range of techniques and devices to secure the airway, depending on the patient’s condition and the clinical context. Key methods include endotracheal intubation, rapid sequence intubation (RSI), supraglottic airway devices, and advanced visualization aids. In cases where these approaches fail, surgical airway interventions are...

Hepatic Drug Clearance: Restrictive and Nonrestrictive Clearance
0 Views •
2025
Hepatic clearance refers to the volume of blood cleared of a drug by the liver per unit of time. It plays a crucial role in drug metabolism and elimination. While hepatic clearance is commonly estimated by subtracting renal clearance from total body clearance, other pathways, such as pulmonary or biliary clearance, may also contribute. However, these pathways are generally less significant than hepatic and renal clearance. Most drugs undergo restrictive clearance, which is proportional to the...

This paper describes different methods of growing Pseudomonas aeruginosa biofilms on cultured human airway epithelial cells. These protocols can be adapted to study different aspects of biofilm formation, including visualization of the biofilm, staining of the biofilm, measuring the colony forming units (CFU) of the biofilm, and studying biofilm cytotoxicity.

Here we describe an effective method for studying dynamics of apoptotic cell clearance in vivo. This method employs live Drosophila embryos as a powerful model for monitoring phagocytosis of apoptotic cells using specific labeling of apoptotic cells and phagocytes.
FAQs
Controlled coughing supports expectoration, whereas chest percussion and postural drainage help loosen and reposition mucus. As secretions move toward larger airways, they become more accessible for removal. These complementary physical actions can therefore support airway patency and effective breathing without treating every technique as interchangeable.
Positive expiratory pressure alters airflow in a way that can help mobilize mucus and direct it toward larger airways. Its value lies in complementing secretion-removal actions rather than replacing expectoration: once mucus has been repositioned, controlled coughing can help clear it. This makes airflow manipulation an important component of Airway Clearance Techniques.
Bronchodilators and mucolytics can serve as pharmacological adjuncts to physical clearance methods. The overview identifies both medication groups as treatments that may enhance airway clearance effects, while physical techniques mobilize and remove secretions. Their relevance is therefore complementary: medication can accompany coughing, percussion, postural drainage, or positive expiratory pressure rather than replace these approaches.
At a general level, the process links mucus mobilization with subsequent removal. Percussion, postural drainage, or positive expiratory pressure can help loosen or reposition secretions, while controlled coughing supports expectoration. Pharmacological adjuncts may also be included when they enhance these effects. This progression connects altered airflow and secretion movement with the practical goal of clearing the airways.
These approaches are particularly relevant in cystic fibrosis, bronchiectasis, and chronic obstructive pulmonary disease, where secretion retention and impaired airway clearance are important concerns. Applying them in these settings aims to improve ventilation, reduce retained secretions, and limit complications associated with obstructed airways. The combination may include physical methods, pharmacological adjuncts, or both.
Expected outcomes from Airway Clearance Techniques include improved ventilation, more effective removal of retained mucus, and better maintenance of airway patency. The overview also links these goals with limiting complications associated with obstructed airways. Outcomes are therefore judged by functional respiratory benefit and secretion management rather than by the use of one technique alone.
The pharmacological perspective focuses on how bronchodilators and mucolytics can support a broader clearance strategy. Rather than isolating drug action from respiratory care, this framework considers medication alongside controlled coughing, percussion, postural drainage, and positive expiratory pressure. That integration connects drug use with maintaining airway patency, supporting breathing, and reducing secretion retention.
