Tracheostomy Care I: Pre-procedural Steps

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 Decannulation

Tracheostomy Decannulation

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...

Tracheostomy Care II: Procedure

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...

Esophageal Perforation-II: Clinical Manifestations and Management

Esophageal Perforation-II: Clinical Manifestations and Management

Esophageal perforations manifest in various clinical forms, influenced by factors such as the perforation's cause and location (cervical, intrathoracic, or intra-abdominal), the extent of contamination, and potential injury to adjacent mediastinal structures. The timing between the perforation occurrence and treatment initiation also affects the clinical presentation.
Clinical Manifestations:

Mitral Stenosis IV: Nursing Management

Mitral Stenosis IV: Nursing Management

A comprehensive nursing assessment is essential for patients with valvular heart disease, which involves any dysfunction of the heart valves that could impact blood flow and overall heart function.Subjective Data Collection:Chief Complaint and Present Illness: Start with the patient's primary concerns, focusing on the onset, duration, and progression of cardiac symptoms such as dyspnea, fatigue, chest pain, and palpitations.Past Medical History: Collect detailed information on any previous...

Cardiomyopathy VII: Pre and Post Operative Nursing Management

Cardiomyopathy VII: Pre and Post Operative Nursing Management

Patients with hypertrophic cardiomyopathy (HCM) and left ventricular outflow tract (LVOT) obstruction who remain symptomatic despite optimal medical therapy may undergo a septal myectomy (Morrow procedure). This procedure involves excising a portion of the hypertrophied septum below the aortic valve using a heart-lung machine to improve blood flow through the LVOT. Effective preoperative and postoperative nursing management ensures successful patient outcomes, minimizes complications, and...

Summary

Vocal cord dysfunction is an overlooked complication after open heart surgery, causing respiratory issues and requiring reintubation. While often resolving, it can lead to permanent vocal cord problems.

Area of Science:

Cardiothoracic Surgery
Otolaryngology
Critical Care Medicine

Background:

Vocal cord dysfunction (VCD) is a potential complication following open heart surgery.
Early recognition and management are crucial for patient outcomes.

Purpose of the Study:

To evaluate the incidence and effects of vocal cord dysfunction after open heart surgery.
To highlight the diagnostic challenges and management strategies for this complication.

Main Methods:

A retrospective analysis of 270 adult open heart surgery cases.
Identification of five cases (1.9%) diagnosed with vocal cord dysfunction between February 1993 and May 1995.

Main Results:

All five patients experienced respiratory insufficiency post-extubation, necessitating reintubation and ventilation.
Diagnosis was delayed in three cases due to lack of awareness.
Three patients required tracheostomy, and two required minitracheostomy; one case of persistent shortness of breath led to arytenoidectomy.

Conclusions:

Vocal cord dysfunction is an easily missed complication post-open heart surgery, potentially causing significant respiratory distress.
Causes may include direct vocal cord trauma, recurrent laryngeal nerve injury from endotracheal tube cuffs, or less commonly, central venous cannulation or cold exposure.
While VCD may resolve, it can result in permanent morbidity in some cases.
