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 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...

Oxygen Delivering System III: Tracheostomy and T-piece

Oxygen delivery is critical in clinical care, especially for patients with respiratory disorders or those undergoing surgical procedures. Various systems, such as tracheostomy and the T-piece, deliver oxygen to the lungs, ensuring adequate arterial oxygenation.
Tracheostomy
A tracheostomy is a surgically created opening (stoma) in the anterior part of the trachea. It is used to establish a patient airway, bypass an upper airway obstruction, simplify the removal of secretions, permit long-term...
Tracheostomy Care II: Procedure01:25

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 and...
Trachea01:22

Trachea

The trachea, commonly known as the windpipe, is a vital part of the human respiratory system. It serves as a passageway for air to travel between the larynx and the bronchi, allowing oxygen to reach the lungs. Let's explore its anatomical features, dimensions, layers of the tracheal wall, associated muscles, and the functions of its parts.
Anatomical Features:
Location: About half of the trachea is situated in the neck, anterior to the esophagus, and extends from the larynx (at the level of the...
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.

Summary

New bedside formulae accurately estimate tracheal tube length in pediatric patients. These calculations improve upon current guidelines for orotracheal and nasotracheal intubation in children, especially those under one year old.

Area of Science:

  • Pediatric Critical Care Medicine
  • Airway Management
  • Clinical Pediatrics

Background:

  • Standard methods for estimating tracheal tube length in children may be inaccurate.
  • Accurate tracheal tube length is crucial for safe and effective intubation in pediatric patients.

Purpose of the Study:

  • To evaluate the precision of current techniques for determining oral and nasal tracheal tube lengths in children.
  • To develop improved predictive formulas for bedside use in pediatric tracheal intubation.

Main Methods:

  • A retrospective analysis of 255 pediatric patients requiring tracheal intubation in a Pediatric Intensive Care Unit.
  • Data collected included patient age, weight, and the final tracheal tube length and internal diameter.
  • Patients with a tracheostomy were excluded.

Main Results:

  • Linear regression analysis yielded predictive formulas for tracheal tube insertion depth.
  • For children over 1 year: orotracheal = age/2 + 13 cm; nasotracheal = age/2 + 15 cm.
  • For children under 1 year: orotracheal = weight/2 + 8 cm; nasotracheal = weight/2 + 9 cm.

Conclusions:

  • Existing Advanced Paediatric Life Support guidelines may underestimate required orotracheal tube lengths in children over 1 year.
  • Novel weight-based formulas for infants under 1 year demonstrated superior accuracy compared to standard charts.
  • Prospective evaluation of the new predictive formulas is recommended.
