Summary
This study introduces an electronic device to assist in nasolacrimal duct intubation (NLDI) by providing audible feedback for stent retrieval. The device safely and effectively located the lacrimal probe in all patients, potentially improving NLDI procedure safety and efficacy.
Area of Science:
- Ophthalmology
- Otolaryngology
- Medical Devices
Background:
- Nasolacrimal duct intubation (NLDI) is a common procedure for treating nasolacrimal duct obstruction.
- Teaching and mastering NLDI can be challenging due to the complexity of endonasal stent retrieval.
Purpose of the Study:
- To investigate the utility and safety of an electronic device designed to aid in the endonasal retrieval of lacrimal stents during NLDI.
- To evaluate the device's effectiveness in localizing the intranasal portion of the lacrimal probe.
Main Methods:
- A prospective interventional case series involving 12 adult patients undergoing NLDI.
- An electronic device with an audible alarm was used for endonasal probe retrieval in all participants.
- Intraoperative rigid nasal endoscopy was performed post-procedure to assess for injury.
Main Results:
- The electronic device successfully localized the endonasal lacrimal probe in all 12 patients.
- Nasal endoscopy confirmed healthy nasal mucosa without any signs of thermal or electrical injury.
- The technique demonstrated safety and efficacy in locating the intranasal stent component.
Conclusions:
- Electronically assisted NLDI, utilizing audible feedback, represents a technological advancement for enhancing NLDI safety and effectiveness.
- The described technique is safe and effective for localizing the intranasal lacrimal probe.
- Further research is warranted to explore its utility in complex cases and as a pedagogical tool for training.

01:15Endotracheal 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...

01:29Suctioning the Nasopharyngeal Airway
Nasopharyngeal suctioning is a procedure to remove secretions from the upper part of the respiratory tract that the patient cannot clear independently. It helps maintain airway patency and prevents complications such as aspiration pneumonia.

01:30Cardiopulmonary 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...
01:17Endotracheal Intubation II: Nursing Management
Endotracheal intubation is a critical procedure that can be lifesaving for many patients with respiratory distress or failure. The role of nursing in managing endotracheal tubes is pivotal, as it involves pre-intubation preparation, assisting during the procedure, and post-extubation care.
1. Nursing Care of Patients Before Intubation
Before the endotracheal intubation procedure, nurses play an essential role in ensuring the process goes smoothly. The nurses must be familiar with intubation...

01:23Tracheostomy 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...
01:24Endotracheal Tube Extubation
Endotracheal tube extubation is a critical procedure in weaning patients from mechanical ventilation. It involves physically removing the oral or nasal endotracheal (ET) tube, marking the final step in liberating a patient from ventilatory support.
Procedure
Extubation removes the endotracheal tube (ETT) from the patient on mechanical ventilation. It requires a well-coordinated, multidisciplinary approach involving physicians, nurses, respiratory therapists, and other healthcare professionals.
