Insights

A novel technique using scalp vein tubing with Crawford silicone tubes significantly reduced extrusion rates in children with congenital nasolacrimal duct obstruction. This simple method prevents common complications, ensuring successful intubation and removal.

Area of Science:

  • Ophthalmology
  • Pediatric Surgery

Background:

  • Congenital nasolacrimal duct (NLD) obstruction is common in children.
  • Silicone tube intubation is a standard treatment, but tube extrusion is a frequent complication.

Purpose of the Study:

  • To evaluate a simple technique for reducing silicone tube extrusion after NLD intubation.
  • To assess the efficacy of using scalp vein tubing with Crawford tubes in pediatric NLD surgery.

Main Methods:

  • Retrospective review of medical records for children over 2 years undergoing NLD intubation with Crawford silicone tubes.
  • A modified technique involved passing one end of the tube through scalp vein tubing before knotting.
  • Complications including tube extrusion, nasal discharge, crusting, and granuloma formation were monitored.

Main Results:

  • Fifty-seven patients (49 unilateral, 8 bilateral) were included.
  • No instances of tube dislodgement, significant nasal discharge, crusting, or pyogenic granuloma occurred before planned removal.
  • All silicone tubes were successfully removed after 3 months.

Conclusions:

  • The described technique of using scalp vein tubing with Crawford silicone tubes appears to effectively decrease the rate of tube extrusion.
  • This method offers a simple solution to a common complication in pediatric NLD intubation.

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.

Endotracheal Intubation I: Procedure01:15

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...

Endotracheal 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...
Tracheostomy: Procedure and Tubes01:28

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...
Endotracheal Tube Extubation01:24

Endotracheal 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.

Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen

Oxygen therapy is a pivotal aspect of medical care, particularly for patients with respiratory ailments. Two prominent oxygen-delivering systems include the Venturi mask and the transtracheal oxygen catheter.
Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...
