Cardiopulmonary Resuscitation V: Advanced Airway Management Techniques

Cardiopulmonary Resuscitation V: Advanced Airway Management Techniques

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...

Cardiopulmonary Resuscitation II: ACLS Airway Management

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...

Tracheostomy Suctioning II: Procedure

Tracheostomy Suctioning II: Procedure

Tracheostomy suctioning is a vital nursing procedure that involves removing secretions from the tracheostomy tube to maintain airway patency and prevent respiratory complications. Nurses need to understand the proper technique for tracheostomy suctioning to ensure patient safety and comfort. In this guide, we will outline the step-by-step process for performing tracheostomy suctioning, including preparing the sterile field, donning personal protective equipment (PPE), lubricating and connecting...

Tracheostomy Suctioning I: Pre-Procedural Steps

Tracheostomy Suctioning I: Pre-Procedural Steps

Tracheostomy suctioning is a critical procedure healthcare professionals perform to maintain a patent airway in patients with a tracheostomy tube. This procedure is necessary when secretions accumulate in the airway, causing respiratory distress. Here is a step-wise procedural guide for performing tracheostomy suctioning using an open system.
Equipment Required
First, gather all necessary equipment: a sterile suction catheter, a sterile disposable container, sterile gloves, a towel or...

Endotracheal Intubation I: Procedure

Endotracheal Intubation I: Procedure

Endotracheal or ET intubation is a critical medical procedure used to secure a patient's airway, often in acute respiratory distress, apnea, upper airway obstruction, ineffective clearance of secretions, high risk for aspiration, or during general anesthesia.
The ET tube comprises various components, including a standard adaptor to attach a bag-valve-mask (BVM) or ventilator, a cuff, a pilot balloon, and radiopaque markings along its length to measure the insertion distance. The tube sizes...

Endoscopic Procedures I: Esophagogastroduodenoscopy

Endoscopic Procedures I: Esophagogastroduodenoscopy

An Esophagogastroduodenoscopy (EGD) is a diagnostic procedure in which an endoscopist uses a flexible, lighted endoscope to visualize the upper gastrointestinal (GI) tract. The procedure includes visualizing the oropharynx, esophagus, stomach, and the first part of the small intestine, the duodenum.
During an EGD, the endoscope can be used to:

Summary

A novel epiglottic repositioning technique successfully corrected supraglottic stenosis/collapse in patients with failed decannulation. This procedure enabled successful decannulation in all treated cases, offering a solution for this uncommon condition.

Area of Science:

Otolaryngology
Surgical Innovation

Background:

Supraglottic stenosis/collapse is an uncommon cause of failed decannulation after tracheostomy.
Accurate diagnosis can be challenging.

Observation:

A retrospective analysis identified 3 cases of supraglottic stenosis/collapse with posterior epiglottic displacement among 8 decannulation failures.
These cases were treated with a novel epiglottic repositioning procedure.

Findings:

The epiglottic repositioning technique involved an external incision to divide and reattach the epiglottis.
Successful decannulation was achieved in all 3 patients who underwent the procedure.

Implications:

This technique offers a viable solution for supraglottic stenosis/collapse.
Diagnosis-directed laryngoscopy is crucial for identifying this condition.
Further research may validate this surgical approach for decannulation failures.
