Insights

Vocal fold immobility (VFI) occurred in 8% of pediatric patients after cardiothoracic surgery. While some surgical factors appeared linked in initial analysis, further research is needed to confirm these associations.

Area of Science:

  • Pediatric surgery
  • Otolaryngology
  • Cardiothoracic surgery

Background:

  • Vocal fold immobility (VFI) is a potential complication following cardiothoracic procedures in children.
  • Identifying risk factors for VFI is crucial for improving patient outcomes and surgical techniques.

Purpose of the Study:

  • To determine the incidence of VFI in pediatric patients undergoing cardiothoracic surgery.
  • To investigate potential associations between surgical factors and the development of VFI.

Main Methods:

  • Flexible laryngoscopy was used to assess vocal fold mobility pre- and post-operatively in 100 pediatric patients.
  • Surgical techniques, potential recurrent laryngeal nerve injury, and post-extubation laryngeal symptoms were documented.

Main Results:

  • The incidence of VFI was 8.0% (8 of 100 children).
  • Univariate analysis suggested associations between VFI and younger age, lower weight, monopolar cautery use, circulatory arrest, and specific vessel ligations.
  • Multivariate analyses did not confirm these associations, possibly due to the limited number of VFI cases.

Conclusions:

  • The incidence of VFI after pediatric cardiothoracic surgery is 8.0%.
  • No factors were definitively associated with VFI in multivariate analysis, highlighting the need for larger studies.
  • Further multicenter prospective research is required to identify definitive risk factors for VFI in this population.

Assessment of Airway, Skin Color, and Use of Accessory Muscles

A thorough assessment of respiratory health is paramount in clinical settings to identify and manage respiratory distress and ensure adequate oxygenation. This article elaborates on the critical aspects of respiratory evaluation, including airway assessment, skin color examination, and the observation of accessory muscle use, which are integral to effectively diagnosing and managing patients with respiratory conditions.

Physical Assessment of the Respiratory Tract II: Palpation01:24

Physical Assessment of the Respiratory Tract II: Palpation

Physical assessment of the respiratory tract is critical in identifying potential health issues. One key component of this assessment is palpation, a technique healthcare providers use to assess the body for abnormalities. This content explores the method of palpation in evaluating the respiratory tract, focusing on thoracic palpation and tactile fremitus.
Thoracic Palpation
Thoracic palpation detects tenderness, masses, lesions, respiratory excursions, and vocal fremitus. The nurse assesses...
Endoscopic Studies II: Thoracocentesis01:26

Endoscopic Studies II: Thoracocentesis

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...

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:

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...
