Summary
Postoperative trachomatous trichiasis (PTT) affects 19% of patients in endemic regions. Factors like age, treatment type, and trichiasis severity influence PTT outcomes, necessitating improved surgical and follow-up care.
Area of Science:
- Ophthalmology
- Public Health
- Infectious Diseases
Background:
- Trachomatous trichiasis (TT) is a leading cause of preventable blindness, characterized by eyelashes damaging the cornea.
- Postoperative trachomatous trichiasis (PTT) represents a significant challenge in trachoma-endemic regions, impacting visual health.
- Understanding the prevalence and risk factors of PTT is crucial for effective trachoma control strategies.
Approach:
- A systematic review and meta-analysis was conducted, searching major scientific databases for relevant studies.
- Included studies were analyzed for heterogeneity and publication bias using I2 statistics and funnel plots.
- A random effects model estimated the pooled prevalence and associated factors of PTT, with results reported using RevMan 5.4 software.
Key Points:
- The pooled prevalence of PTT was found to be 19% across the included studies.
- PTT incidence exceeded World Health Organization (WHO) recommendations, highlighting a need for improved management.
- Factors associated with lower PTT included younger age, single-dose oral azithromycin use, and minor trichiasis pre-surgery.
Conclusions:
- Postoperative trachomatous trichiasis (PTT) presents a significant public health concern in trachoma-endemic areas.
- Interventions such as post-operative azithromycin, surgeon training, and diligent follow-up are vital for reducing PTT recurrence.
- Enhanced patient education and surgical best practices are essential for minimizing the long-term impact of PTT.

01:21Tracheostomy Decannulation
303
Tracheostomy decannulation is a significant milestone in the liberation of mechanically ventilated patients. Despite its importance, there is no universally accepted protocol for this procedure. This demands an evidence-based, individualized approach.
Description of the Procedure
Decannulation refers to the permanent removal of the tracheostomy tube, signaling the resolution of the condition that initially necessitated the tracheostomy. The process requires a well-coordinated interplay between...

297
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.

01:26Tracheostomy Suctioning I: Pre-Procedural Steps
810
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...

301
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.

01:28Tracheostomy: Procedure and Tubes
852
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...
