Tracheostomy Care II: Procedure

555
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: Procedure and Tubes

1.6K
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 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...

Area of Science:

  • Cardiovascular Surgery
  • Biomedical Engineering
  • Neurosurgery

Background:

  • The Jarvik 2000 left ventricular assist device (LVAD) utilizes a postauricular cable and pedestal, similar to cochlear implants.
  • Current placement leads to mechanical cable stress from neck movements and cosmetic concerns due to apparatus visibility.
  • These issues can impact patient quality of life and device longevity.

Purpose of the Study:

  • To optimize the placement of the Jarvik 2000 LVAD pedestal.
  • To mitigate mechanical cable stress and improve the aesthetic outcome.
  • To enhance patient comfort and device durability.

Main Methods:

  • The pedestal's location was adjusted from the lower parietal bone to a position superior to the transverse sinus, near the mastoid process.
  • The internal cable was rerouted through the retromastoid pathway, a standard neurosurgical approach.
  • Preoperative computed tomography (CT) scans were used to assess skull thickness for safe fixation.

Main Results:

  • The revised pedestal position aims to reduce continuous mechanical stress on the driveline cable caused by neck rotations.
  • The new location offers improved cosmetic concealment of the device apparatus.
  • Skull thickness at the adjusted site is adequate for secure device fixation.

Conclusions:

  • Repositioning the Jarvik 2000 LVAD pedestal superior to the transverse sinus offers a viable solution to mechanical and cosmetic drawbacks.
  • The retromastoid pathway provides a safe route for internal cable management.
  • Careful preoperative neurosurgical evaluation is essential to ensure patient safety and optimal device implantation.
