Tracheostomy Care I: Pre-procedural Steps01:16

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.
Required Equipment
The equipment necessary for tracheostomy care includes:

Tracheostomy Suctioning I: Pre-Procedural Steps

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...

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...

Kidney Transplant II: Surgical Procedure

Preoperative ManagementThe primary goals of preoperative management in kidney transplantation are to optimize the patient’s metabolic state and prepare them for surgery through diet adjustments, necessary dialysis, and tailored medical treatment. This phase also involves comprehensive infection screening and patient education about the surgical procedure and postoperative care to improve outcomes and adherence.Medical ManagementA comprehensive evaluation is required for both the living donor...

Area of Science:

  • Ophthalmology
  • Surgical Education

Background:

  • Trabeculectomy (glaucoma surgery) rates are declining in the US.
  • Ophthalmology residents have fewer opportunities for surgical practice.
  • A need exists for accessible surgical training models.

Purpose of the Study:

  • To introduce key trabeculectomy surgical steps using a food-based wet laboratory model.
  • To assess the feasibility and efficacy of this novel surgical simulation.

Main Methods:

  • A surgical model using a lime (sclera surrogate) and chicken skin (conjunctiva surrogate) was developed.
  • Trainees practiced trabeculectomy flap creation, suturing, and conjunctival incision repair.
  • A survey evaluated the model's realism, preparation efficacy, and ease of use.

Main Results:

  • Both experienced and novice surgeons rated the model 4/5 for surgical preparation and tissue realism.
  • The model received a 1/5 rating for ease of setup and material acquisition.
  • 93.5% of respondents recommended the model for implementation at teaching hospitals.

Conclusions:

  • The food-based trabeculectomy model is inexpensive, safe, and provides realistic surgical practice.
  • It minimizes biohazard risks and is practical for global use in training.
  • This model offers a viable alternative for glaucoma surgery education.
