Insights

Pushed stent intubation successfully treated complex congenital nasolacrimal duct obstruction (CNLDO) in 59.1% of cases. This method offers reduced operating time and easy placement for pediatric patients.

Area of Science:

  • Ophthalmology
  • Pediatric Surgery

Background:

  • Congenital nasolacrimal duct obstruction (CNLDO) is a common condition in infants.
  • Complex cases of CNLDO may require surgical intervention.

Purpose of the Study:

  • To evaluate the success rate of pushed stent intubation for complex CNLDO in children.
  • To assess clinical outcomes and parental-reported symptoms post-procedure.

Main Methods:

  • Prospective study at a single academic center.
  • 44 eyes with complex CNLDO underwent pushed stent intubation.
  • Outcomes assessed at 6 months, including clinical signs and residual symptoms.

Main Results:

  • Complete resolution in 59.1% (26/44 eyes) of cases.
  • Mean follow-up was 9.0 months.
  • Factors like sex, age, prior probing, and discharge did not significantly impact failure rates.

Conclusions:

  • Pushed stent intubation is an effective treatment for complex CNLDO in children.
  • The procedure is associated with shorter operating times and simpler placement.
  • Clinical signs and symptoms were alleviated post-treatment.

Suctioning the Nasopharyngeal Airway01:29

Suctioning 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.

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...

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...

Tracheostomy: Procedure and Tubes

A tracheostomy is a surgical procedure that creates an artificial opening into the trachea, typically at the second or third cartilaginous ring level. This opening allows the insertion of a tracheostomy tube, which can replace an endotracheal tube, provide mechanical ventilation, bypass an upper airway obstruction, or remove accumulated tracheobronchial secretions.
Tracheostomy tubes can be made of semiflexible plastic (polyurethane or silicone), rigid plastic, or metal, and they come in...

Tracheostomy Care II: Procedure

Tracheostomy care is an essential nursing skill that involves cleaning and maintaining a tracheostomy tube to prevent infection and other complications. Here's a step-by-step guide explaining each procedure with its rationale. Note that disposable gloves are to be worn at all times and changed as often as needed to maintain a sterile work environment, and to protect both patient and healthcare worker.
Step 1: Perform hand hygiene, and put on personal protective equipment: gown, gloves, mask...

Tracheostomy Care I: Pre-procedural Steps

A tracheostomy is a surgical technique that involves making an incision in the neck to provide access to the trachea. It is frequently used in medical conditions such as airway obstruction and prolonged mechanical ventilation. Effective nursing management is crucial for the long-term success of a tracheostomy.
