Summary
Simulation training significantly improves ophthalmology residents' trabeculectomy surgical skills. These gains are immediate, sustained for a year, and support integrating simulation into surgical education.
Area of Science:
- Ophthalmology
- Surgical Education
- Medical Simulation
Background:
- Trabeculectomy is a critical glaucoma surgery.
- Developing surgical competency requires effective training methods.
- Simulation-based education offers a controlled environment for skill acquisition.
Purpose of the Study:
- To assess the impact of trabeculectomy surgical simulation training on resident ophthalmologists' core surgical skill competency.
- To measure the immediate and sustained effects of simulation on trabeculectomy skills.
Main Methods:
- A post hoc analysis of a randomized controlled trial involving 49 resident ophthalmologists across 6 African training centers.
- Participants were randomized to an intensive 1-week trabeculectomy simulation course or a control group.
- Surgical competency was evaluated using a validated tool assessing 8 key trabeculectomy skills.
Main Results:
- Simulation training led to a significant increase in median surgical competency scores from baseline (2.88-3.25/16) to post-intervention (11.67/16).
- The observed skill improvement was maintained at 3 months and 1 year post-intervention (P=0.0001).
- Highest competency gains were noted in releasable suturing, scleral flap formation, and scleral incision.
Conclusions:
- Intensive simulation-based surgical education positively impacts core trabeculectomy skill development in resident ophthalmologists.
- The rapid and sustained improvement in skills supports the formal integration of simulation into ophthalmic surgical training curricula.

Procedures for Kidney StonesMedical intervention is necessary when kidney stones or renal calculi are too large to pass spontaneously (typically greater than 5 millimeters) when stones are accompanied by symptomatic infection (such as fever or pyelonephritis), when they impair kidney function, or when they cause persistent symptoms like severe pain, nausea, or urinary retention. Additionally, patients with only one kidney or those who cannot be treated with medical management also require...

924
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.

Tracheostomy suctioning is a vital nursing procedure that involves removing secretions from the tracheostomy tube to maintain airway patency and prevent respiratory complications. Nurses need to understand the proper technique for tracheostomy suctioning to ensure patient safety and comfort. In this guide, we will outline the step-by-step process for performing tracheostomy suctioning, including preparing the sterile field, donning personal protective equipment (PPE), lubricating and connecting...

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.

Thoracentesis(Thoracocentesis), commonly known as pleural tap, is a medical procedure where a 22 gauge needle is inserted into the pleural space, the area between the lung and chest wall. This procedure is commonly performed to diagnose or treat various respiratory disorders.
Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...

53
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...
